Gao Junshan said: "Yes, that's just an idea." Do you think it's that easy to make a torpedo? Our current conditions are not yet ripe, so don't think about the torpedo problem for the time being, let's take a look at your shell production workshop! ”

Director Wu pointed to a building in front of him: "Chief Shan, look, the factory is in front, let's take a rest in the factory first, and then go down to the workshop for a walk." ”

Gao Junshan said with a smile: "The guest is as good as the host, and the guest is as the host as he pleases." ”

They went up to the factory director's room on the third floor of the factory department, and after Gao Junshan sat down, factory director Wu began to introduce Gao Junshan to the shells produced by their artillery factory.

The shells produced in this artillery factory were mainly supplied to the Zheng He-class battleships, so the model was relatively simple, with only five types of shells, 9 pounds, 18 pounds, 32 pounds, 50 pounds and 70 pounds, with calibers of 4.5 inches, 5.5 inches, 6.5 inches, 7.5 inches, and 8.5 inches respectively.

Although there are only five types of shells, there are several types of warheads, as well as second- and third-stage shells.

The so-called multiple warheads include: ordinary warheads, self-detonating warheads, multiple warheads, and incendiary warheads.

Ordinary warheads are divided into solid iron bullets and solid lead warheads, hollow iron bullets and hollow lead warheads;

The self-detonation warhead is filled with explosives in the hollow warhead, and after the shell is ejected, it will explode within a certain period of time, and it controls the time of explosion through a sealed fuse, which will generally explode within 1-2 minutes after the shell is launched;

A multi-bomb warhead is to place 2-3 small missiles in the warhead, and the warhead will self-detonate after hitting a certain distance, and there are two types of missiles: incendiary and self-detonatory;

The incendiary warhead is filled with aluminum powder and magnesium powder in the hollow warhead, which are filled in proportion, and the warhead will automatically burn after being shot, forming a fire ball.

Gao Junshan was very interested in incendiary bombs, and he said happily: "Even incendiary bombs can be produced, and your contribution to explosives will bring us a greater advantage in naval warfare." ”

Immediately afterwards, he praised all the technicians and craftsmen of the artillery factory.

The use of incendiary bombs in naval warfare in the era of wooden sailing ships will bring a more violent destructive effect, and only a few incendiary bombs can completely disable a first-class battleship of this era.

"Let's go, take me to the workshop now." Gao Junshan stood up.

Director Wu also stood up and asked, "Chief Shan, look at that workshop first?" ”

"The Molotov cocktail workshop, of course."

Director Wu said to a security director surnamed Xiong in their factory: "Director Xiong, you go to the incendiary bomb workshop to arrange it first, and the emperor will go to inspect it." ”

Director Xiong was ordered to leave first.

Director Wu suggested to Gao Junshan: "Chief Mountain, should we go to the technical department first to have a look, and see the internal structure of the incendiary bomb more intuitively from them." ”

Gao Junshan agreed with Director Wu's suggestion: "Okay, go to the technical department to have a look." ”

The technical department is on the second floor of the factory, and when I came to the technical department, I saw that the two rows of desks were full of scientific and technological personnel, about 30 people, and they were all working with their heads down.

Captain Wu said loudly to these scientific and technological personnel: "The mountain chief has come to see you, you should put down the work at hand first and warmly welcome the arrival of the mountain chief!" ”

After Director Wu finished speaking, he applauded first, and these people quickly got up and followed Director Wu to applaud and welcome.

Director Wu said: "The mountain chief came to visit you today, please give us a lecture!" ”

The applause was even more enthusiastic.

Gao Junshan stood in the center of the two rows of tables, saying goodbye, and the entire technical department was silent.

"You've worked hard! As a result of your hard work, you have made great contributions to the research and development of ammunition, and have made great contributions to the development of our navy to the world and to the ocean. Because of your outstanding performance and the achievements of your outstanding work, it will benefit China and mankind, your cause is great, and your cause will be forever beautiful! ”

After Gao Junshan finished speaking, there was another warm applause.

Gao Junshan asked to see the drawings of the incendiary bomb, and the director of the technical department took out a drawing from the safe, came to an empty table, and explained to Gao Junshan while unfolding it: "This is a drawing of an 8.5-inch caliber incendiary bomb warhead, and this incendiary bomb can be arbitrarily assembled on the 8.5-inch projectile body, and through the launch of the gun, it can burn the enemy ship." ”

Gao Junshan could read the drawings, and he interrupted the words of the director of the technical department and asked, "What kind of incendiary agent is filled in the bomb cavity?" ”

The head of the technical department replied: "Aluminum-magnesium mixed powder." ”

Gao Junshan asked again: "How do you do the refining of magnesium?" ”

Director Wu hurriedly replied: "The magnesium powder is not extracted by ourselves, the magnesium powder and aluminum powder we use are provided to us by the smelter, and our scientific and technological personnel have done thousands of proportional matching experiments on these two metal powders to make today's incendiary bombs." ”

"How much do you produce?"

Director Wu replied: "Because the refining of magnesium powder is very difficult, so the production of incendiary bombs is very limited, as far as our factory is concerned, we cannot guarantee that there are raw materials for production every day, about 100 rounds of incendiary bombs can be produced every month, we have three artillery shell factories in the country can produce incendiary bombs, according to this progress, the national average is only 300 rounds per month!" ”

"How is our magnesium powder refined so far?"

"I know that." The director of the technical department hurriedly answered, "We weigh aluminum powder and magnesite and dolomite according to a certain ratio, and then grind magnesite and dolomite into powder, mix them with aluminum powder, and under 1100~1170 °C and vacuum conditions, after 6~8 hours, aluminum powder is used as a reducing agent to produce magnesium. ”

Director Wu added: "Therefore, it is very difficult to refine this magnesium powder, and the raw materials we ration are very limited, so the production volume is limited. ”

Gao Junshan nodded in understanding, and then said, "Let's go to the workshop now!" ”

Director Wu had a smile on his face: "Yes, yes." ”

So, under the guidance of Director Wu, Gao Junshan came to the incendiary bomb workshop.

The entrance of the workshop is also heavily guarded, this workshop is just an assembly workshop, workers transport hollow warheads from the quilt workshop, and there are craftsmen here to carry out careful filling work, and the loaded warheads must be transported to the arsenal from here for safekeeping.

Therefore, this workshop is not very large, only 200 square left behind, compared to other workshops, it is much smaller.

Gao Junshan walked into the workshop, there were two craftsmen who were loading a 9-pound bomb warhead, and Gao Junshan's arrival made them put down their work.

Gao Junshan asked the two craftsmen some relevant knowledge, encouraged them again, and then said, "Don't disturb your work, you continue!" ”
