Ding Quankun began to introduce the current progress of gun research at Tsingshan Machinery Factory.

"Because the production of guns is extremely difficult, especially the steel barrel and the steel barrel has extremely high requirements for steel technology, we have not been able to find a qualified steel gun barrel material."

"However, our laboratory has already mobilized a large number of capable forces, and at the same time, we have also invited a large number of technical backbones from state towns and county towns to carry out technical research!"

Everyone actually didn't understand the technical difficulty mentioned by Ding Quankun, the steel barrel and cannon barrel?

They know about steel barrels, but this thing doesn't seem to be so difficult, many large-scale arsenals can basically produce steel barrels, at most the quality is good.

As for the steel barrels, they don't understand them at all, and now the guns are either bronze or iron, but there are no steel barrels.

It is normal for them not to know, because the steel barrels and barrels studied by the Aoyama Machinery Factory are not prepared for front-loading weapons, but for rear-loading rifled weapons.

Breez-loading rifled weapons, on the other hand, have extremely high requirements for steel barrels.

Taking the barrel as an example, the worst must be the barrel quality of the Fuyuan musket.

However, it is not without reason that the Fuyuan musket has been bought in several surrounding states and has become the favorite weapon of large and small feudal towns and even bandits.

You must know that there are many other large arsenals in Nanhai Prefecture that can produce muskets, and they are basically all steel barrels, and the Luo'an Arsenal is one of them.

However, the muskets they produced competed with Fuyuan muskets in the market.

The reason is very simple, it is because the steel barrel of other people is of good quality and reliable.

Simple and reliable, convenient and practical, excellent performance, and not expensive, this is the Fuyuan musket, which almost represents the highest level of contemporary smoothbore guns.

But why can't other arsenals make muskets of the same high quality as Fuyuan muskets?

Naturally, because they can't make a good barrel.

The goal of the Aoyama Machinery Factory today is to create a barrel of comparable quality to the Fuyuan musket, even if it is worse, but not too bad.

At least, it must also reach the barrel quality of steel smoothbore guns produced by other ordinary arsenals, otherwise after carving out the rifling, the rifling will have to be polished after a few shots.

Not to mention the barrel of the artillery, the steel barrel, which is also extremely technically difficult.

Ding Quankun didn't care about everyone's doubts, and he continued to talk about the project results of Tsingshan Machinery Factory.

"In order to accumulate experience and train technicians and workers, during this period of time, we began to organize people to produce bronze artillery and iron-cast artillery on our own, especially the new nine-pound field artillery in service of our army!"

"However, limited to our finishing ability and the technical level of the workers, the new nine-pound field gun we imitated is much worse than that of the Nanzhou Machinery Bureau in terms of performance, although we have thickened the barrel to ensure the range and accuracy, so that the imitation of the product exceeds expectations in weight, and the weight of the whole gun has reached 1,350 kilograms, but the accuracy has decreased slightly!"

As soon as he heard this, Kong Deyi directly expressed his support: "It's okay to be heavier, it's okay to be almost accurate, it's good to be able to produce it ourselves, otherwise, when the life of the barrel of this batch of new guns on hand expires, there will be no use for artillery!" ”

When Ding Quankun heard this, his face was a little embarrassed: "We only imitated one for testing, and there is no way to mass produce it for the time being. ”

When Comte heard this, his face was disappointed.

Now the situation is so tense, although it is only a few months away from next year, but what will happen in a few months is something that no one can say, in case of a few large-scale battles in these months, the existing artillery will have to be wiped out in minutes!

But Ding Quankun said that there was no way to mass produce it for the time being, so he could only not speak.

Today's meeting is a report meeting, not a free discussion meeting, and no one other than the speaker is allowed to intervene without authorization, otherwise it will become a vegetable market.

Perhaps feeling a little embarrassed that he couldn't get the artillery, Ding Quankun took the initiative to speak: "However, we can't mass produce the new bronze cannon, but some iron-cast artillery cannons can already be mass-produced. ”

However, as soon as Kong De heard this, he directly ignored Ding Quankun.

What is that nine-pound light mortar cannon, can he, an old artilleryman, still know it?

It was a toy at best, the firing range was not even four hundred meters, and this was still the maximum firing range, as for the effective firing range, Daheng's artillerymen did not formulate the concept of effective firing range for this light mortar at all.

Because this thing has a maximum range of 400 meters, and the landing point error can reach 30 meters, what is the effective range with this accuracy......

This accuracy and range are basically useless for contemporary artillery units.

The nine-kilogram light mortar newly produced by the Qingshan Machinery Factory can be regarded as the first self-produced artillery product of the Qingshan Machinery Factory, and the technical content is actually very low.

The reason why Qingshan Machinery Factory chose a light mortar gun as the first mass-produced artillery is actually because this thing has the lowest technical content, and there are basically no technical problems.

In fact, at first, Lin Ziran wanted to make mortars, but later found that this idea was not realistic, and the current technology could not make the mortars he wanted at all.

The biggest feature of the mortar is that it is lightweight, followed by a good range when firing at a large angle, and then it has an ultra-high rate of fire, and the combination of the three is a mortar.

The combination of these three, the requirements for manufacturing technology are actually very high, first of all, the quality of the barrel is very high, otherwise it is impossible to use a thin barrel to fire shells, and ensure the chamber pressure, and with the chamber pressure there is a range, which means that the seamless steel tube is needed as the barrel.

If there is no seamless steel pipe, then the weight cannot be controlled, and if the existing steel barrel technology is used, if you want to ensure the chamber pressure, then the barrel needs to be made very thick, and the weight will be greatly exceeded.

Secondly, if you want to have an ultra-high rate of fire, you need to use a metal fixed ammunition that combines copper shells, warheads, propellants, and primers, and use a reliable primer firing method.

It is a pity that Tsingshan Machinery Factory has not been able to complete the design and development of metal fixed ammunition.

Don't look at the mortar is very rudimentary, but it lacks key technology, in fact, it can't be made at all.

If it can be made, it is not a mortar, but a light mortar made by the Aoyama Machinery Factory.

The light mortar cannon is also not the first initiative of Lin Ziran or Qingshan Machinery Factory, the Daheng Army has long been equipped with this thing, and now many feudal towns also use it, but this thing has never been the main artillery, so the sense of presence has always been very low.

This is mainly due to the fact that they all position these small mortars as artillery and belong to artillery equipment.

As for Lin Ziran, he actually didn't plan to let the artillery unit belong to this thing.

He directly positioned this nine-pound light mortar gun as an infantry weapon, and directly assigned it to the infantry regiment......

Because there are only more than 30 kilograms in the barrel of this thing, and the base is only more than 30 kilograms, and the whole gun weighs less than 70 kilograms.

This thing can be carried and run by two soldiers on the battlefield!

For the artillery troops, this thing is rubbish, but Lin Ziran thought, since the artillery can't be used, throw it to the infantry troops. It's a cannon!
