Chapter 302 Facing the bombing of Japanese aircraft, what should we do?
"Papapa!" Immediately afterwards, the heads of the departments applauded and congratulated the birth of the highest-tech group.

The applause was endless. Professor Zhuang and the others were nothing. After all, they had expected it, but Zhao Zhangcheng, who had just arrived from the Liushugou Arsenal, was stunned.

what's the situation?
How can I even get into this supreme science and technology group that looks so good?
Zhao Zhangcheng's face was full of confusion, looking at Chen Kang with doubts and desires in his eyes.

He wondered why...

Feeling Zhao Zhangcheng's gaze, Chen Kang smiled without giving any explanation. After the applause fell, he continued: "Then each department will introduce itself and report the recent situation."

The words fell, and his eyes turned to the chief of the general affairs section sitting on the left.

"Hello, the expert of the highest technology team. I am Lu Yuan, the chief of the General Affairs Section. I am reporting on the responsibilities and recent status of the General Affairs Section. Currently, the General Affairs Section is responsible for the transportation, road construction, and logistical support of each factory and mine."

Lu Yuan, the head of the General Affairs Section, stood up abruptly and saluted the three people facing him: "As of today, there are 490 registered members of the General Affairs Section, including 5 Dodge trucks, 1 German-made red-headed car, and 1 large convertible. A total of 120 horse-drawn carts, 94 mule carts, and 100 bullock carts are all in transit, with a daily capacity of [-] tons. In terms of roads, a Yushen Highway is being built with a gravel roadbed. This is all the information about the General Affairs Division. Please refer to it .”

"Thank you Comrade Lu." Professor Zhuang got up and took the documents from Lu Yuan.

"Hello, Professor Zhuang, and student Yu. I am Zhuang Qianding, the chief of the Ordnance Engineering Department. I am reporting the responsibilities and recent status of the Ordnance Engineering Department. The Ordnance Engineering Department has jurisdiction over the Liushugou Central Arsenal, Nanyaogou Repairing Institute, and Shuiyangou Repairing Institute. , including administrative, technical cadres and workers, a total of 180 seven people, without an old-fashioned lathe, a vertical deep-hole drilling machine, vises, and some molds for grenade shells."

Bo Huishuang, the head of the ordnance department, stood up, raised his hand in salute, and reported on the situation of the ordnance department: "The Liushugou Arsenal can now produce wooden handle grenades, and the designed daily output has been increased from 200 to 600, and the actual daily output is limited by Limited to gray pig iron supply is sufficient, only 30 pieces."

"The Ordnance Engineering Division is organizing the official rifle project and the [-]mm mortar project. It is expected to complete the imitation task of the [-]mm mortar within eight months, and will return to the stage of small batch production. The imitation of the official rifle will be completed within one year. Production, there is no information about the Ordnance Institute, please check the minimum technology team."

"Thank you, Comrade Hu."

Professor Zhuang thanked again and took over the extremely important military production materials in the base area.

After Zhuang Qianding was seated, the remaining eight departments of the Military Industry Bureau spoke in succession to report the situation.

"The Public Works Division has jurisdiction over the electric furnace steel plant, sulfuric acid plant, petroleum plant, low furnace iron plant, coking plant, and a total of 740 workers and technical cadres in each plant. The electric furnace steel plant produces 240 kilograms of electric furnace steel per day, and the annual output is about 88 tons. The sulfuric acid plant produces 9.5 tons of sulfuric acid per day, the petroleum plant produces 1.2 tons of oil per day, and refines a total of 500 liters of gasoline and diesel.

"The Fire and Explosives Division is under the jurisdiction of the Fire and Explosives Factory, with 47 employees. It can produce single-base propellants, double-base propellants, and heavy explosives. The daily output has increased from 300 kilograms at the beginning of the factory to 450 kilograms now."

"The Mineral Resources Division has jurisdiction over seventeen mines including Shenmu Coal Mine, Shenmu Iron Mine, Yimeng Crystalline Graphite Mine, Jingbian Copper Mine, and Yulin Limestone Mine, which can independently supply iron, copper, coal, oil, natural gas, limestone, Seventy kinds of raw materials such as quartz sand, graphite, alkali, mirabilite, salt, boron, phosphorus, etc., the mining volume and related data of each mine are here, please have a look."

Through the brief information given by the seven departments of the Military Industry Bureau, Zhao Zhangcheng and Bo Hui now basically grasp the overall situation of the entire wartime production plan.

When the person in charge of the Mineral Resources Division finished speaking, Hu Zhigang, who was sitting in the front position, was confused. Looking at the crowd, he knew what to do.

Aware of Hu Zhigang's reaction, Yu Hua did not delay announcing that he would withdraw from the discussion on the site selection of the steel plant, but signaled him to speak: "Comrade Zhao, please tell me about the withdrawal of the 60mm mortar project. Headquarters pays low attention, after all artillery is very important to us."

The 60mm mortar project received little attention from the headquarters, and while the official rifle was important, the artillery was even more important.

Hearing Yu Hua's explanation, Professor Zhao Zhangcheng and Bo Hui nodded to show their understanding.

"Heads, experts from the lowest technology team, the 60mm mortar project has completed the design drawing, and organized workers outside the factory to process and manufacture the prototype gun. We encountered a small problem in the place where the gun barrel was made. We fixed the 60mm seam. Steel pipe." Hu Zhigang stood up without a word, recalled the development experience and learning process in the arsenal during this period, sorted out the wording a little, and reported the current status of the project slowly.

The words fell, and then sat down.

Now, with the help of artillery experience provided by Hu Zhigang, the Liushugou Arsenal 60mm mortar project has completed all the designs and retreated into the actual manufacturing process, and how to manufacture seamless steel pipes has become a stumbling block for the technicians and engineers of the arsenal. The smallest puzzle behind the workers.

How to make a barrel with an inner diameter of 60 mm?
After listening to this situation, Zhao Zhangcheng pondered for a while, turned his head to look at Lu Yuan, and said: "On this issue, Lu Yuan and I will go to the arsenal before the meeting starts. It's hard and hard."

There are no two ways to manufacture mortar tubes, one is the process of rolling seamed steel pipes, and the other is the processing of barrel blanks. Considering economic factors, the latter is usually selected. After all, the gun barrel blanks are boring. The cost of processing is several times less than the latter. Only without the barrels of low-bore pressure artillery such as howitzers, tank guns and cannons, the barrel blank boring process will be used.

The rolling process of seamed steel pipe is divided into cold rolling and hot rolling. The mainstream process is cold rolling, and China basically has a hot rolling process.

Feeling Professor Zhuang's gaze, Lu Yuan understood what he meant, and remembered this matter in his mind.

"Thank you, Professor Zhuang." Hu Zhigang was stunned when he heard these words. He was overjoyed and quickly thanked him.

Zhao Zhangcheng shook his head: "It's thanks."

……

"Okay, now let's end the discussion on the location of the retrograde steel plant. Professor Zhuang, I want to know the suggestion of the minimum technology team first. This is the map of the Shaanxi-Gansu-Ningxia base." After the report on the [-]mm mortar project is completed, Yu Hua announced his retirement from the main topic of today's meeting, then took out a map and placed it on the table, looked at Professor Zhuang and asked.

The heads of various departments in the conference room cheered up and turned their attention to the lowest technology group directly opposite.

"The location of the steel plant is particularly required to be as close as possible to the source of raw materials, with convenient transportation and rugged terrain. Taking into account the factors of war, it should meet the requirements of places that are easy to defend and difficult to attack. After discussions with Lu Yuan, there are no eight places that have been initially determined. , Yulin, Jingbian, Mizhi." Zhao Zhangcheng and Lu Yuan looked at each other, then looked up at the map of the border area behind them, and pointed their fingers at eight identical places.

Yu Hua thoughtlessly, respectfully said, "Professor Zhuang, can you explain in detail?"

When Bai Huishuang heard the words, she turned her eyes to Lu Yuan.

"Director Chen, fellow comrades, Jingbian is located in the northwest of Yancheng, bordering Ikezhao League and backed by Hengshan Mountain. The territory is rich in water resources, and there is no Jingbian copper mine. It is only 200 kilometers away from the raw material supply site of Shenmu. It is very convenient to build roads or build railways in the future.”

Lu Yuan got up and hurriedly gave the reasons and advantages and disadvantages of choosing Jingbian: "Militarily, if the Japanese army wants to retreat and attack Jingbian, they can either choose to cross the Yellow River from the northwest of Shanxi, cross Luliang and Hengshan, or choose Baotou from Suiyuan. Cross the Yellow River, and then Ikezhao League and Yulin."

Hearing Lu Yuan's analysis, everyone present nodded, and Chen Kang and Yu Hua, the heads of the General Affairs Section, who were combat staff officers, gave their affirmative attitudes.

Shaanxi is located in the loess lowland area, with simple terrain, vertical and horizontal mountains, and extremely convenient transportation.

"Compared with Jingbian, Yulin is closer to Ikezhao League. It is backed by Hengshan Mountain. It is rich in water resources and mineral resources. It is about 80 kilometers away from Shenmu. The road and railway construction conditions in the supply area are excellent, similar to Jingbian under the military, relying on Luliang and Hengshan as a natural barrier, but due to the proximity to the Yikzhao League, the danger is slightly higher than that of Jingbian."

Lu Yuan continued, pointing his left hand to Yulin: "Actually, from an industrial point of view, Yulin is the most suitable place for industrial development among the eight locations. In the future, we can rely on Ikezhao League to establish Yuyi Industrial Zone."

The development potential of Yulin is extremely profound. There is no Jingbian copper mine on the right, no Shenmu coal and iron mine on the left, self-produced limestone and quartz sand and other minerals, and there is no super raw material base of Yike Zhaomeng in the north, which can accommodate 700 million tons of steel per year. Industrial area of ​​production.

Hearing the reasons and advantages and disadvantages given by Lu Yuan, no one looked at Yulin at the same time, thinking that this seemingly ordinary place has so few advantages.

"Where's Mizhi?" Yu Hua asked.

Lu Yuan said: "The advantage of Mizhi lies in the fact that it is located in a hill, with the best danger, it is close to Shenmu and Yulin, and has abundant water resources and natural gas resources. A steel plant, and the construction of roads and railways is not difficult. My speech is over, thank you, Xiaojia.”

Mizhi is surrounded by the Hengshan Mountains and is close to the Dinghe River. It is rich in water resources and mineral resources. However, the area of ​​this place is small, and the capacity of the 3.5-ton steel plant is barely enough. It is basically possible to expand it recently.

As Bo Hui dragged out the reasons for the selection of the eight places and their advantages and disadvantages, the conference room fell silent, and everyone present except Professor Zhuang was lost in thought.

Jingbian...

Yulin...

Rice fat...

"Deputy Team Leader Yu, I don't have a problem." At this moment, Bai Hui, the person in charge of the General Affairs Section, suddenly raised her hand and sent a message.

Lu Yuan responded, "Senior Lu, please speak."

"Faced with the bombing of Japanese aircraft, what should we do?"
