Imagine if it was really what these regiment leaders applied for, each regiment had hundreds of long artillery grenades in hand, and then used 82 guns to blow up the Japanese...then the Japanese could still stay in North China?

At least the Japanese don’t dare to build turrets and blockhouses anymore, right?

But here's the problem. With the current production capacity of the arsenal, so many long artillery grenades can't be produced for two or three years. This is a good thing.

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

Compared with 82-force artillery shells, which can be directly cast from gray iron or ductile iron and then rough and finely machined, the production of long artillery grenades is much more difficult.

The long artillery grenade seems to have a very simple structure. It is a steel pipe with a tail fin. The tail fin is a propellant package, and the steel pipe is an explosive. There is a threaded joint in front of the steel pipe, which can be connected to a 110mm or 150mm warhead. It is very

Simple right?

But where do the steel pipes come from? It’s good to know that smelters can now guarantee the supply of gun barrel steel and gun barrel steel. After all, there are still many gun barrels, mortar barrels, and rocket launcher tubes to make.

Up to now, grenade tubes are still made of drilled blanks after forging steel rails, and the launch tubes of fireworks cannons are also made of pig iron if they can be cast.

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

.

As for the processing of long artillery grenades... First of all, the smelting plant does not have the ability to manufacture seamless steel pipes. The steel pipe body used to make long artillery grenades can only be manufactured by forging and roughening the outer circle and then drilling. Drilling

, it requires the use of a large number of drill bits. These are consumable tools and are not easy to come by.

The key is that even if there are a large number of drill bits, the drilling time and material consumption will be very large, which in turn involves the consumption of electricity, steam power, and water power... The projectile that has been drilled still needs to be finished.

Check the inner hole and outer circle once to ensure the accuracy of the weight.

In short, this is a very complicated production process. Just a steel tube shell for a long grenade requires the use of four basic procedures: forging, rough turning, drilling, and fine turning. It also needs to be installed later.

Tail, stabilizer and other procedures.

As for the fine work here, not just anyone can do it, it requires a master craftsman with high skills.

Therefore, even though Hu Changyi really hoped to satisfy the requests of these regimental leaders and political commissars, he was still unable to do so. In other words, if he had the mechanical industry level of the Mao Xiong family, this would not be a problem at all.

"So, what did the Republic of China do during these golden ten years? The compradors themselves made a fortune, 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 a souvenir?

Jiuzhai is still hot in winter. This hotness is because men, women and children from all villages gather together in the sand-making workshops. The hot fire of sand-making warms their bodies and can also give them strength for sand-making production.

Oh, even those teachers who are literate hold classes in the finished work shed made of sand. One by one, the warm grenade shells are piled in the work shed to dispel the cold in winter. When the children write with talc pens

The hands are not cold.

You said someone was burning cow dung and stewed sweet potatoes in a corner of the work shed? That must have been the work of the naughtiest boys in the village. By the way, the smell of dried cow dung and stewed sweet potatoes... ahem, the older generation should still return it.

Do you have a memory?

Compared to the outside world, Jiuzhaigou was a paradise during the war years. In addition to handing over part of the grain received as military rations every year, the people's families were still very wealthy. The key is that the military rations turned over were stored in the arsenal.

I worked in his workshop for a period of time and made money again.

This is nothing. The little chickens that followed the trend of the Ninth Detachment and raised them this year have already become full-fledged and can lay eggs. The little roosters have long since turned into big roosters, and they have one egg every day.

Early in the morning, I heard the big roosters in the whole village crow non-stop, making it difficult for people to sleep peacefully.

However, as the new year is approaching, and as they need to supplement nutrition for the wounded in the headquarters hospital, the cadres on the Eighth Route have bought an unknown number of big roosters from the people. Well... the old hens are reluctant to part with them.

Those that are sold will not be sold unless they are raised for a few years until they are no longer able to lay eggs.

The key is to learn to use rice bran and chicken manure to raise maggots this year. The chickens that eat these maggots will grow extraordinarily fat and lay many eggs, which are also oily.

No, Mrs. Hu from Hujiacun got up early as usual and came to her chicken coop. She looked at the more than thirty plump hens in the pen and felt so beautiful. Huh? There is another little one.

Is the hen laying eggs? The little Kunzi at home is a little weak, and the first nest of eggs is the most filling. Give him some vegetables!

"Kick, cluck, cluck... Oh, it's too cold today, and there aren't any bugs for you to eat. Let's eat some feed with Lao Huang... feed... is this the way to say it, right?" Aunt Hu picked up the eggs and said,

While muttering, he fed some finely chopped green silage to the hens and kicked the big rooster next to him.

"You can't lay eggs just by eating them. If it wasn't for you to step on them, I would have stabbed you long ago..." It was you who muttered and left the chicken coop, ignoring the hurt rooster in your heart and turning around to feed your family.

old cattle fed silage feed.

"Boss, please wake up... The militiamen are about to gather... Get up quickly, and follow the boss to grind rice today. Xiaocui, get up, the Women's Rescue Association is having a meeting today..."

Aunt Hu has a very loud voice, which is much stronger than the big rooster in the village every morning.

Aunt Hu's shouts woke up Hujia Village, and voices began to appear in each house. Soon smoke rose from the cooking pots, chickens and dogs began to make noises, and the children also got up. Soon after, loud slogans began to be heard in each village.

The sound rang out on the road, and the soldiers of the ninth detachment began their daily 5-kilometer cross-country tour.

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

After taking part in the morning run and having breakfast in the Hujiacun detachment canteen, Hu Changyi first went to look at various locations of the Ninth Detachment, and then went to the arsenal.
