Chapter 283 Xihuashan Tungsten Mine!
However, the content of this northern emergency telegram that brought the ultimate shock is far more than that.

The main information of the emergency power in the north is divided into four points, one is about oxygen top-blown converter technology, the other is vertical deep hole drilling machine, the third is the base area machinery manufacturing plan proposed by Professor Zhuang Qianding, and the fourth is that Professor Yu Hua and Zhuang are going to Site investigation based on location.

If the oxygen top-blown converter technology brings shock and unimaginability, then a single vertical deep hole drilling machine with a daily processing of 35 pieces breaks the cognition.

The total smelting time for a single time is 30 minutes, and the production of 96 tons of steel per day sounds too far away. closest.

Making guns has always been the team's goal.

On the technical requirements and difficulty of making guns, it is obvious to all. Nowadays, there are only three arsenals with gun manufacturing capabilities in the country, Taiyuan Arsenal, Hanyang Arsenal, and Gongxian Arsenal.

If it is placed in 1931, Shenyang can be added.

The core of making a gun is the barrel.

One is the gun hole and the other is the rifling.

What is the concept of a single vertical deep hole drilling machine that processes 35 pieces a day?
Take Yan Xishan’s Taiyuan Arsenal as an example. The peak scale of the Taiyuan Arsenal was during the Central Plains War, with 1.5 employees and [-] pieces of machinery and equipment. With such a huge scale, the monthly production of rifles was [-]. The number reaches about three thousand.

Now, only three of these vertical deep hole drilling machines are needed, and the monthly output of processed barrel blanks can be as high as [-] pieces.

It is true that the monthly output of barrel blanks is not equal to the actual output of rifles. After all, it is still limited by the efficiency of rifling marking, but this does not mean that the importance and value of vertical deep hole drilling machines can be ignored.

Once the efficiency of rifling marking reaches the same level, it is not easy to reach the scale of thousands of rifles per month.

The boss clearly understands the importance of the vertical deep hole drilling machine. His heart beats faster and his breath trembles. However, this is not over yet. With the rollout of the blueprint for the mechanical manufacturing industry in the base area described by Professor Zhuang, it has reached the world's third-class machinery manufacturing level in six and a half years. The goal, like a red-hot brand, fell in his heart.

He doesn't know what the world's third-rate machinery manufacturing level means, but he understands that if this goal is achieved, the organization will definitely be stronger than it is now.

"It's unbelievable, it's really unbelievable. The annual output can reach 3.5 tons of oxygen top-blown converter, a single vertical deep hole drilling machine with a daily processing of 35 pieces, independent research and development of machinery manufacturing equipment, and construction of machinery manufacturing. These technologies are connected in series. An industrial chain covering iron and steel, machinery manufacturing and ordnance production has been constructed, plus the sulfuric acid industry and explosives industry... I suddenly have an illusory feeling, as if this is a dream."

"It's not a dream, it's reality, what should we do now?"

"Naturally... Seize this precious opportunity and call back to the North. First, the organization will immediately raise the remaining funding gap, assist in purchasing materials and machines, and fully support the steel plant plan. Second, the vertical deep hole drilling machine needs to be protected and shipped as soon as possible. Arrive at the base area, three, agree to implement the independent research and development of mechanical equipment and machinery manufacturing plan, four, agree to Yu Hua and Professor Zhuang's request to visit the base area for site selection, let them do their best to protect the safety of Yu Hua and Professor Zhuang Qianding, and do not publicize it until Arrive at the base. After that, in principle, the identities of the two of them are required to be kept highly confidential, but their safety must be ensured.”

"I agree."

"I agree."

"In addition, the Japanese army has already started the war. Our title of 'mass production before the war' is a bit inappropriate. I think it can be renamed as mass production during wartime, which is more appropriate."

"Wartime mass production...good."

……

With the order from the decision-making level, the telegrams were sent to all parts of the country, and the highly disciplined and coordinated organizational machine entered a state of full operation, carrying out organized purchasing activities.

materials and equipment.

In terms of materials, in addition to the parts owned by the base, it is necessary to purchase important industrial raw materials such as copper, silicon steel sheets, chromium, tungsten, molybdenum, and vanadium.

Among them, red copper, silicon steel and tungsten are in the first place. Red copper is used for oxygen gun nozzles and heat-dissipating copper pipes, silicon steel is used for high-power DC motors, and tungsten, as a rare element, is used as an additive metal to smelt and produce hard materials for machine tools. Quality alloy - tungsten steel.

In terms of equipment, there are basically no bases. It is necessary to purchase high-power DC motors, diesel generators and other industrial production auxiliary equipment. There are as many as [-] types, and the number of each type is as large as possible.

High-power DC motors are mainly used for equipment drive, starting with five kilowatts of power, involving a variety of different power specifications, and the upper limit of power specifications depends on the limit that can be purchased.

Whether it is the tilting device of the oxygen converter, or the turbocharger and turbo compressor of the air separation plant compressor, it is inseparable from the power support of the DC motor.

If you can buy it in the early stage, you can buy it. No matter how high the price is, you should use it first, and then carry out imitation or independent research and development in the middle and late stage.

Benefiting from the original 298 million silver dollars and gold, the organization in the most difficult period has an original capital that can barely support the operation of the entire plan.

Not much money, but enough.

Southern region, Gannan, Dayu County.

A hazy light rain fell in the sky, which lowered the temperature a little in southern Jiangxi, which was in full swing in July, and took away the feeling of burning like a fire.

Dayu, also known as Nan'an, is located in the southwest of Ganzhou, where the three places of Ganzhou, Guangdong and Hunan meet. This county was originally ordinary in Chinese history, but it is famous all over the world because of a mine.

The world lacks tungsten, but China does not lack it. The tungsten mine in China is headed by Dayu Xihua Mountain. - This sentence is a common cognition worldwide.

Xihuashan Tungsten Mine, the earliest tungsten resource mined in China, has the highest reserves and excellent quality. Its tungsten output accounts for more than 99% of the total national tungsten output and more than 80% of the global tungsten output.

Today, [-]% of the tungsten sand produced by the Xihuashan Tungsten Mine is sold to Europe. It is one of the few export goods that has achieved a 'trade surplus' in the Chinese export commodity catalog.

As for these buyers of tungsten sand...

Naturally, it is Desan who is extremely deficient in tungsten.

Tungsten has extremely high application value and role in the military. Armor-piercing projectiles using tungsten alloys as materials have significantly improved penetration performance and lethality. This is simply the most ideal armor-piercing projectile material, no one.

In addition to the military application of armor-piercing projectile materials, in the civilian field, tungsten alloy-based carbide machine tools are simply perfect tool materials, with extremely high hardness and wear resistance, giving tungsten alloys unprecedented performance.

The most interesting thing is... Dayu County, which owns the Xihuashan Tungsten Mine, was once the old Soviet area.

Yes, the old Soviet area.

Today, Dayu County welcomed a guest from Ganzhou City, a special guest with an unusual identity and a batch of gold bars.
