Starting from the bright sword to engage in military industry

Chapter 696 Chapter 705, it is difficult to expand production capacity
Imagine, if it is really the same as what these regiment leaders applied for, each regiment has hundreds of long artillery grenades in their hands, and then uses 82 to bomb the devils... so the devils can stay in North China?At least the devils dare not build gun towers and bunkers, right?

But here lies the problem. As far as the current production capacity of the arsenal is concerned, it is impossible to manufacture so many long artillery shells within two or three years.

Others may not know that, as the director and technical leader of the arsenal, Hu Changyi knows how difficult it is to produce long artillery grenades.

Compared with the 82-force artillery shells, which can be directly cast with gray iron or ductile iron and then rough-turned and fine-turned, the production of long artillery shells is not a little bit more difficult.

Long artillery grenade, it seems that the structure is very simple, a steel pipe with a fin, the tail is a propellant package, the steel pipe is an explosive, and there is a threaded joint in front of the steel pipe, which can be screwed to a 110mm or 150mm warhead.very simple, right?

But where did the steel pipe come from?It is good to know that the smelter can guarantee the supply of gun barrel steel and gun barrel steel. After all, there are many gun barrels, mortar barrels, and rocket launcher tubes.

Up to now, grenade launchers are still made of forged steel rails by drilling holes, and the launch tube of the fireworks cannon can also be cast with pig iron.

Why casting molding should be simple?Because when casting and then lathe, the processing amount will be very small, it is only necessary to leave enough finishing processing amount for rough turning, and then finish turning to the number, and then turn out the threaded interface of the fuze.

As for the processing of long cannon grenades... First of all, the smelter does not have the ability to manufacture seamless steel pipes. The steel pipe projectiles used to manufacture long cannon grenades can only be made by forging and roughing the outer circle of rough turning and then drilling.Drilling requires a large number of drill bits, which are consumable tools and are not easy to come by.

The key point is that even if there are a large number of drill bits, the time consumption and material consumption of drilling will be very large, which in turn involves the consumption of electricity, steam power, and water power... The projectile body after drilling requires precision turning One inner hole and outer circle to ensure the accuracy of the weight.

In short, this is a very complicated production process. Just the steel shell of a long artillery grenade needs to use four basic procedures: forging, rough turning, drilling, and finishing turning.Later, programs such as empennage and stabilizer need to be added.

As for the fine car here, it doesn't mean that anyone can do it, it needs a master craftsman with high craftsmanship.

Therefore, although Hu Changyi very much hoped to satisfy the requests of the regiment leaders and political commissars, he was unable to do so.In other words, if this has the mechanical industry level of Mao Xiong's family, this will not be a problem at all.

"So, what did you do in the golden decade of the Republic of China? The compradors made their own fortunes, but the country fell further and further behind..."

Hu Changyi put away these application documents and carefully put them into the system space.Well, Hu Changyi can handle these documents by himself. Are these handwritten documents also commemorative?

Jiuzhai in winter is still hot. The hot reason is that men, women and children from all villages have gathered in the sand-making workshop to warm up their bodies by the heat of the sand-making and produce a lot of strength for the sand-making.

Oh, even those literacy teachers teach in the finished workshops that have been turned into sand.The warm grenade shells were piled up in the shed one by one, dispelling the winter cold, and the children's hands were not cold when they wrote with a talc pen.

You said someone was burning cow dung and braised sweet potatoes in a corner of the shed?That was definitely a good thing done by the naughtiest boys in the village.In other words, the taste of stewed sweet potatoes with dried cow dung... Ahem, people of the older generation should still have memories, right?

Compared with the outside world, Jiuzhai is a paradise during the war years.In addition to having to hand over part of the grain received as military rations every year, the people's families are still very rich.The point is that the military rations handed in are earned back after working for a period of time in the workshop of the arsenal.

It's not a big deal, it's not that the little chick who followed the trend and learned to raise with the Ninth Team this year, has already been fully fledged and able to lay eggs.The little roosters have long since turned into big roosters. Every morning, the big roosters in the village crow non-stop, making it difficult to sleep soundly.

However, as the end of the new year was approaching, and as the wounded in the headquarters hospital needed to be supplemented with nutrition, the cadres of the Eighth Road had already bought an unknown number of big roosters from the common people.Uh... Old hens are always reluctant to sell. If they are not raised for a few years, they will not lay eggs until they are old, so they will never be sold.

The key is to learn to use rice bran and chicken manure to raise maggots this year. The chickens that grow up after eating these maggots grow extra fat, lay more eggs, and the eggs are also oily.

No, Mrs. Hu from Hujia Village woke up early as usual, and came to her chicken coop. Looking at the thirty or so fat hens in the pen, she felt so beautiful.Huh?Another pullet laying eggs?The little Kunzi at home is a bit impatient, and it happens that eggs in the head are the most filling, so give him more food!
"Hehehehehe... Oh, it's too cold today, and I don't have any bugs for you to eat. Let's eat some feed with Lao Huang... Feed... Is that the way to say it?" Mrs. Hu picked up the eggs, while Mumbling, while feeding some finely chopped silage feed to the hens, he also kicked the big rooster next to him.

"You can't just eat eggs, if it wasn't for you to step on eggs, I would have given you a knife..." Aunt Hu muttered and left the chicken coop, ignoring the big rooster who was hurt in her heart, and turned her head to feed the rooster at home. The old cattle are fed with silage.

"Boss, call the boss to wake up... The militiamen are about to gather... The second family, get up quickly, and follow the old family to mill rice today, Xiaocui, wake up, the Women's Rescue Association is meeting today... "Ms. Hu has a very loud voice, which is much stronger than the big rooster in the village every morning.

Mrs. Hu's shout woke up the Hujia Village, and people's voices began to appear in each house. Soon the smoke rose, the chickens and dogs started to make noise, and the children also got up.Not long after, loud slogans began to sound on the roads between the villages, and the soldiers of the Ninth Detachment began to cross-country 5 kilometers early every day.

Hu Changyi naturally wants to take part in running, on the one hand to ensure physical fitness, and on the other hand to be more energetic for this day.

After participating in the morning jog and having breakfast in the cafeteria of the Hujia Village Detachment, Hu Changyi first went to the various stations of the Ninth Detachment to look around, and then went to the arsenal.

"Changyi, are the technicians and backbone workers you have prepared ready? They will leave early in the morning the day after tomorrow." The first thing Minister Zhang said when he saw Hu Changyi was to arrange for the workers.
