Chapter 324 (2/2)

For this kind of high hardness carbon steel, Addison is naturally very interested. After more than half a year's test in his metallurgical laboratory, he finally produced a high hardness carbon steel with properties close to T13 steel.

Although this kind of steel can't be compared with the real T13 steel, it can be used to process other steels in this era.

Of course, Shi Xiong also told him that adding some other metal elements to the raw materials can also greatly change the performance indicators of steel.

Anyway, as long as it's something the stone bear knows, he will tell edian. Although stone bear does not know the specific performance values of most metal materials, he only needs to tell Addison what elements need to be added to smelt these alloy steels.

As for whether he can experiment, it depends on the skill of this French alchemist.

And Jack Williams got a lot of high-performance steel with the help of dean. With the steel, Williams can try all kinds of processing equipment.

With the joint efforts of the two people, the first deep hole drilling machine of gaoshu tribe was finally successfully made when it came to the full moon (December).

This kind of simple machine tool is driven by water, driven by gear and made of high hardness carbon steel. It can be said that it is the most advanced machine tool in the world.

This kind of machine tool can drill holes up to 90cm in depth. If the depth exceeds 90cm, the workpiece needs to be rotated twice.

Now the barrel length of Ferguson's rifle is 1.4 meters, so if you want to process the barrel of a Ferguson's rifle, you need to drill from both ends.

Before the production of Ferguson rifle barrel is cast, but in the case of using black powder as propellant, it is not a problem. However, in the future, the guns of gaoshu tribe must be fired with non flooded gunpowder (homophonic), so the cast barrel can not be used.

Compared with black powder, the power of non flooded powder is much greater. If the cast barrel is used again, it is easy to explode.

However, for now, the rifles used by the expeditionary army still use black powder as propellant.

But production of new barrels has begun. With specific data, the second, the third and the N drilling machines can be produced continuously.

As for the new broaching machine for rifling, Williams has developed it for a long time. This kind of broaching machine, which also uses water as power, is more efficient than manual broaching machine. If the broach is replaced by the newly developed carbon tool steel, the efficiency of broaching machine will become higher.

In any case, in the past five months, the weapon making of gaoshu tribe has never stopped.

Not only the rifle, but also the barrel. However, compared with the processing difficulty of rifle barrel, the processing difficulty of casting barrel is much lower.

Therefore, the production speed of the catapult is very fast. If it wasn't for the hard casting of the grenade, the stone bear would like to have a catapult by hand.

It's much more difficult to cast a grenade for a catapult than for a barrel for a catapult. From modeling to pouring, even a highly efficient skilled worker can only cast seven or eight grenades a day. The main limitation of casting speed is modeling.

Otherwise, the number of grenades will always be the bottleneck of the large-scale promotion of the catapult.
