Invincible Zhengde

Chapter 267 Iron Heart Second Update

The original steelmaking level of Daming was not good, and the furnace temperature was not high, which made the forged pig iron too brittle, wrought iron too soft, and it was difficult to control the melting point. There were many bubbles, the structure was simple, and the strength was not as good as copper cannons, and it was far less convenient to use copper.However, with the establishment of the steel factory, Daming's steel output soared, and the quality was good enough to try to use it to cast cannons.

It's just that what kind of material is needed needs to be tried again and again, and the proportion of the alloy is difficult to grasp.

Zhang Yong pulled the cannon and fired the cannon. It seemed that there was real progress. How could Zhu Houzhao be unhappy? He had been waiting for a day for a long time.

"Going back to Your Highness, it's still not good!" Zhang Yong said with a little embarrassment: "Two of our cannons have just exploded, and the rest are also distorted and deformed." For fear of Zhu Houzhao's disappointment, Zhang Yong quickly added: "But our The iron-core copper cannon has been successfully cast, and the effect is very good, even if it is loaded with granular gunpowder, there will be no problem."

Zhu Houzhao laughed immediately, nodded and said, "That's very good, hurry up and take Bengong to have a look."

Steel cannons won’t work, so it’s good to use iron-core copper cannons first. It’s also cheaper than copper cannons. Technology is something that needs to be improved slowly, and it’s definitely not something that will happen overnight.

Seeing that Zhu Houzhao was interested, Zhang Yong immediately showed a smile on his face, and quickly said: "His Royal Highness, please!" He made a gesture of invitation to Zhu Houzhao, and then hurriedly led the way, which is to show himself to His Royal Highness Zhang Yong didn't dare to be negligent when it came to meritorious deeds. You must know that this is a fatal matter.

If you do well, after such a thing, you will naturally be rewarded. If you do not do well, at least you will not be punished.But if His Royal Highness is dissatisfied, then things will be difficult to handle.

Zhu Houzhao didn't say anything. You don't need to forgive at this time. Your forgiveness will only make the people below bolder and less concerned about you. Make them feel awe, otherwise they will not be obedient.

A group of people soon arrived at the test site, where the cannons had been arranged. Zhu Houzhao walked over and stroked the barrel of the cannon. The cold touch made Zhu Houzhao nodded in satisfaction, and turned to look at Zhang Yong. Zhu Houzhao He smiled and asked, "Tell me!"

"Yes, Your Highness!" Zhang Yong quickly came up and explained to Zhu Houzhao: "This cannon is made of cast copper, with iron inside, slightly curved at the front and rear, with a mouth like a spiral. Carved inscriptions on flowers, with six bulges, two or four coins for medicine, four or eight coins for iron, carried on a four-wheeled cart, the shaft is one zhang, two chi and one inch long, and can be pushed by horses or manpower."

Zhu Houzhao nodded lightly after listening to Zhang Yong's words. Obviously this is a light muzzle-loading smoothbore gun.

It is loaded with shotguns, and the iron is sprayed out, and a dozen can be a large piece. Its function is basically the same as that of the tiger squatting gun, but its power is much greater than that of the tiger squatting gun.The tiger crouching cannon is 2 feet long from the head to the tail, with 7 iron hoops added to the whole body. The cannon head is supported by two iron claws, and there are iron trippers. The total weight is 36 catties.Before firing, the gun body must be fixed on the ground with big iron nails. Each shot can be filled with 5 small lead or pebbles weighing 100 yuan, and a large lead bullet or stone bullet weighing 30 taels is used to press the top. Bullets big and small flew out together, making a thunderous sound, with great lethality and radiation range.

The shooting distance of the tiger squatting gun is not far, only about 500 meters. In Zhu Houzhao's view, the tiger squatting gun is the mortar of this era.

The iron-core copper cannon in front of him is basically in line with Zhu Houzhao's idea of ​​a field cannon. Under the current transportation conditions, the field cannon requires convenient and quick mobility, like the Hongyi cannon made in the late Ming Dynasty. The road as a whole went astray. Most of the Hongyi cannons are about 3 meters long, have a caliber of 110-130 mm, and weigh more than 1 ton.

This kind of artillery is obviously the heavy artillery used by warships. It cannot be used in field battles at all when it is moved to land. There are two situations in which it can play a role, that is, defending the city and attacking the city. Field battles are absolutely not acceptable.The first is to defend the city. Some equipment can indeed achieve the purpose of defending the city very well.When besieging the city, the opponent is huddled in the city and cannot come out, so we can calmly mobilize artillery to bombard.

However, there are actually very few such extreme battles. Most of the time, the two sides fight each other, so field artillery is very important.

Of course, Zhu Houzhao also made cannons. Various types of cannons form a series and form the Ming Dynasty's tactical system, but it is not now.Turning back to look at Zhang Yong with a smile, Zhu Houzhao said appreciatively: "It looks pretty good, but I don't know how to fight. Let me try a few shots and let Ben Gong see the power."

"Yes, His Royal Highness!" Zhang Yong bowed quickly, although he was still sure about the Iron Heart Bronze Cannon he made, but at this moment Zhang Yong was still very nervous.

It's okay if it's done well, but if something goes wrong, I really can't explain it clearly.

Although he was very nervous and worried, Zhang Yong hurriedly called people to prepare. The people below were playing with the cannon all day long. Naturally, they were very familiar with it. They quickly placed the cannon, and then began to load the gunpowder and iron. Afterwards, the torch was also picked up, and then stood quietly waiting for Zhu Houzhao's order.

"His Royal Highness, get ready." Zhang Yong came to Zhu Houzhao's side and said cautiously.

Zhu Houzhao nodded, and said expressionlessly: "Okay, let's start!" Zhu Houzhao looked at the scarecrow target in the distance, not knowing what effect it would have.

Accompanied by Zhu Houzhao's order, the flame ignited the fuse, and after a burst of squeaks, the artillery made a loud bang and a bang, and there was a feeling of shaking the earth, and a puff of white smoke rose instantly When he got up, Zhu Houzhao could see the irons flying out like rain. Although the scarecrows were wearing armor, this blow directly caused a lot of damage to the scarecrows.

Needless to say, some scarecrows were directly blown out when the iron iron hit them, and some armors were directly smashed.

Although the armor used here is not Da Ming's new plate armor, but the previous armor, but this is enough to show the power.Seeing this scene, Zhu Houzhao nodded in satisfaction, which is very good. With a weight of 110 catties, it is convenient for transportation. When encountering difficult roads, it can be carried over, and basically there will be no major problems.

"Zhang Yong, you did a good job. Some good Shu brocade and tea came from the womb a few days ago. I will ask Liu Jin to bring you some later." Zhu Houzhao said with a smile, and at the same time did not forget to provoke discord.This is called public and private convenience, and Zhu Houzhao has long been accustomed to this kind of operation, and it can be said that he is familiar with it.
