In fact, the development of such 76mm mortars and cannons is thanks to Jack Williams and David Adion, the two European alchemists who followed the stone bear first.

The former is an Englishman who is proficient in machinery manufacturing, while the latter, although a Frenchman, has an outstanding talent in metal smelting.

With them, and with the help of the alchemists who were later brought by Hank and the guidance of Stone Bear, Jack Williams finally succeeded in improving the steam engine, and at the same time, he also made a large-caliber Precision boring machine for artillery boring.

The processing technology of artillery is much higher than that of rifles, especially the processing technology of barrels and metal materials, which are extremely demanding.

Shixiong knows very well that although he has produced grenadiers and mortars, these two weapons belong to the category of small calibers. Even if the caliber of the 55 mortar can be regarded as a medium caliber, the range is still limited. The power of this weapon.

Therefore, in order to ensure the homeland security of the future Indian Empire, the research and development of large-caliber artillery must be put on the agenda.

To develop large-caliber artillery, the first thing to solve is the problem of metal materials. The 76mm caliber is only two centimeters larger than the 55mm caliber, but there is a huge gap in the requirements for metal materials.

And whether it is a grenadier or a mortar, the requirements for the barrel are not very high, but if you want to develop a real howitzer or cannon, then the requirements for the metal material of the barrel are raised by more than one grade.

The steel smelting formulas that Shixiong had in his hands before were at best able to make some heavy weapons such as grenades or mortars. It would be a long way from making a more powerful cannon or even a howitzer with a longer range.

Therefore, the smelting of metal materials has become the most critical part.

However, David Adion was there, and the stone bear knew the performance of some metal materials in later generations, so under his guidance, David Adion made countless attempts and finally found a few The smelting formula of a qualified metal material.

After constant elimination and experimentation, David Adion finally determined a steel that can be used to build a 76mm cannon or howitzer barrel.

But even so, the life of a barrel made of this steel is not very long.

Like the 76 mortar barrel made of this kind of steel, it can fire up to three hundred and forty rounds, but when used to make howitzer barrels, the life of this type of barrel is immediately reduced to only 120 rounds. about. And if it is used to make a more powerful cannon barrel, the life of the barrel will be reduced, and it can only fire up to ninety to one hundred rounds.

This type of barrel life is obviously not enough, but Shi Xiong can't help it for the time being.

The material is not something that can be made by just making it. It takes countless attempts to find the best formula. And now there are no electric furnaces, even converters and flat furnaces. It is really good to be able to make such steel with the only earthen blast furnace at hand.

With steel that barely meets the requirements, Jack Williams can cast the corresponding machinery.

While David Adion was thinking about the material formula, Jack Williams started to improve the steam engine under the guidance of Stone Bear and began the development of large-diameter boring machines.

In fact, at this time, Mr. James Watt, who was far away in Europe, had already produced an improved steam engine several years in advance. However, due to the same limitation of materials, Watt's improved steam engine has not been used on a large scale.

In the original historical time and space, the improvement of the Newcomen steam engine was completed in 1765, but because the materials used to make the cylinders did not meet the requirements, and the process for making the cylinders did not meet the requirements, this improved Newcomen The door steam engine has not been widely used.

It was only after Watt and John Wilkinson met in 1774 that the machining process of the steam engine cylinder was solved.

Speaking of this John Wilkinson, I have to mention the world's first boring machine that can precisely boring large-caliber barrels. This type of boring machine was made by John Wilkinson. And he also used this technology of processing artillery barrels to make steam engine cylinders for Watt, which allowed Watt's improved steam engine to be promoted on a large scale.

Shixiong pointed out that the boring machine made by Jack Williams that can accurately boring the barrel of a large-caliber artillery was a technique that was stolen from John Wilkinson.

In this era, the boring machine technology of John Wilkinson is naturally very secret, but the body of the unsupportable stone bear contains a soul from later generations. In later generations, Wilkinson's boring machine technology has no confidentiality at all, and this technology has been backward and indistinguishable from the primitive people.

If it weren't for the nature of Shi Xiong's work in his previous life, he would not have specifically understood this kind of old-fashioned technology.

As a result, I didn't expect that the understanding of the previous life would be used in this life.

Jack Williams had built this boring machine and an improved steam engine model from wood long before the new metal materials were available. Therefore, after David Adion’s new model passed the test, Jack Williams immediately built several boring machines and steam engines in the shortest time.

The 76 mortar was quickly developed and passed the test, and now Jack Williams's focus is on the 76mm cannon.

There are already prototypes of this cannon, and it is also being tested.

Of course, this 76mm cannon was imitated by Stone Bear pointing Jack Williams according to the later French Miss 75.

In the original historical time and space, the French launched a cannon that shocked the world in 1897, the famous M1897 75mm cannon.

When the Armstrong breech gun installed by other European powers in the nineteenth century only had two shots per minute, the French introduced this M1897 75mm cannon equipped with a retreating machine. Reaching an amazing reloading speed of 15 rounds per minute, at the limit, it can even reach a reloading speed of 30 rounds per minute~www.readwn.com~ Such a reloading speed in that era is like the stone bear using grenadiers in this era The barrel is as incredible as the mortar.

Moreover, the total weight of the M1897 75mm cannon is less than 1,200 kilograms, and the effective range is 8.5 kilometers. Therefore, when this artillery was launched, it immediately won the nickname of "Miss France 75"...

The artillery developed by the Cherokee is a fake Miss 75 under the guidance of Shixiong.

As for the shells, Jack Williams has also developed a machine that can make all-metal shell shells under the guidance of Shixiong.

Even the boring machine for precision boring of the barrel has come out, and the machine that makes all-metal shells can’t help Williams.

And now Shixiong has smokeless gunpowder technology, Shaokizha's technology, and even lightning mercury technology. The foundation for making all-metal shell shells is already in place...
