One of the biggest problems in the ore steam plant was that the steam hammer as an alternative to the crusher had not yet been invented.

Chongzhen has personally approved and sent the documents for the civilianization of gunpowder, and with the documents of the imperial court, Zhu Yu, the head of the factory, dispatched some gunpowder craftsmen to start making paper tube gunpowder.

The mills have been remodeled, and the mills, with their gear linkages, and steam engines, have been transported by water to the three ore steam factories.

Zhu Shun returned to the hall of Beijing Normal University, ready to personally lead a group of talented students to conquer the steam hammer.

After more than a month of separation, when he returned to the Jingshi University Hall, what he didn't expect was that the steam hammer had been invented by the sixth disciple Bi Mingjue.

Follow the verandah to the No. 6 experimental courtyard, which is transformed into the No. 2 experimental courtyard, and the whole is roughly a steam plant.

A boiler room was built in the corner of the steam building, where steam was transported through an iron pipe and a steam hammer was placed in the middle.

The steam hammer is about 2 meters high and consists of an impact body, an anvil, a cylinder, a piston rod, and a guide key.

The appearance resembles a combination of a Newcomen steam engine and a Watt steam engine.

Bi Mingjue, who was wearing a plain robe, saw Zhu Shun walk into the No. 6 experimental courtyard, put down the improvement drawings in his hand, and walked over: "Teacher." ”

Zhu Shun picked up Bi Mingqi, who was saluting, and walked straight to the steam hammer in the middle: "Start the steam hammer." ”

There was also a group of genius students in the No. 6 experimental courtyard, and after saluting respectfully, they stood next to them excitedly.

They participated in the design of this steam hammer, and the mountain chief came to watch it himself, and there was a touch of joy and excitement in his heart.

Bi Mingqi motioned for a genius student to burn the boiler, and as puffs of smoke rose from the boiler room, the steam was transported through an iron pipe to the cylinder of the steam hammer.

Driven by steam, the cylinder piston drives the piston rod, and the piston rod drives the impact body and begins to do up and down reciprocating motion.

"Bang!"

The impact body instantly smashed on the anvil, and because it was an anvil made of a hard bluestone disk, there was no harsh metal impact, only a dull sound.

In order to prevent the impact body from rotating, a guide key is designed, and the direction of the steam hammer is controlled by the guide key.

After the demonstration of the use of the steam hammer, Bi Mingqi took out a report and handed it to Zhu Shun.

Zhu Shun took over the report and began to check the data of the steam hammer.

Impact weight: 8 tons.

Stroke: 1.5m.

Speed: 40r/min.

Impact force: 48 tons.

Zhu Shun saw the impact force of 48 tons and was very satisfied with this data, no matter how hard the ore was, under the impact of 48 tons of force, it could only be broken to pieces.

The speed also exceeded Zhu Shun's expectations, reaching 40 beats per minute.

At present, no special steel has been studied, but ordinary steel is used to forge piston connecting rods, which is too fast and can easily cause steel breakage.

For this 40 times, Bi Mingqi should have spent a lot of brains.

The steam hammer had already been invented, and Zhu Shun asked people to send the design drawings to Chen Qu, so that he could build a batch of steam hammers as soon as possible and send them to the ore steam factory.

The steam hammer invented by Bi Mingjue, in addition to this kind of heavy-duty steam hammer specially used for ore steam factories, there is also a light-duty steam hammer.

Bi Mingqi led Zhu Shun to the other side of the factory, where there was also a steam hammer, but the impact body was much smaller, only 0.5 tons.

The supply valve in the boiler room was opened, and the light steam hammer was put into operation.

The lightweight steam hammer allowed Zhu Shun to see the movement of an electric small motor.

The 0.5-ton steam hammer, driven by steam, keeps smashing on the anvil, reaching an astonishing 100r/min.

It was almost equivalent to two hits in a second, and the speed was so fast that Zhu Shun could hardly see the shape of the steam hammer, leaving a series of movement tracks.

This is the real role of the steam hammer as an industrial machine tool.

The Ming Dynasty's workshop forging any armor weapon must be constantly beaten, and this kind of beating can only be beaten by the blacksmith with his own strength, and four or five times a minute is already very fast.

Knock for a while, but also stop and rest.

The steam hammer is tireless and does not need to rest, as long as the boiler room provides steam, it can continue to beat at an astonishing speed of 100r/min.

And the key point, the weight of the hammer.

The hammer in the blacksmith's hand is no more than a few dozen catties at most.

The light steam hammer is said to be light, which is a heavy steam hammer weighing 8 tons, and the weight of the impact body is 0.5 tons, which is converted into catties.

A thousand pounds.

A dozen pounds, four or five times per minute.

One is a thousand pounds, and it is hammered a hundred times per minute.

The revolution that steam hammers have brought to the forging industry is absolutely subversive.

With the invention of the steam hammer, the speed of forging the steam engine and various new machinery of the Beiping Machinery Bureau will be raised to a new level.

Although Zhu Shun has no specific data in his hand, it is conservatively estimated that the second-generation steam engine that can only be forged in three months will only take one month at most.

With the establishment of the ore steam factory, the gap of the steam engine will become larger and larger, and the steam hammer just solves the disadvantage of the slow forging of the steam engine.

Not only the steam engine, but also the first artificially forged steam hammer, through this first steam hammer, the speed of forging the steam hammer in the future will also be greatly improved.

This is the role of industrial machine tools.

Half a month later.

The gypsum steam plant, which was built entirely of cement, was completed.

Supporting water tower transportation system, gunpowder blasting, steam hammer, mill and other facilities have also been installed.

Zhu Shun and three nobles, members of the West French Party, and a large number of talented students from Beijing Normal University, stood on a high slope not far away, watching the first operation of the first ore factory in the Ming Dynasty.

As the steam engine pumped water continuously, water from the water tower poured into the concrete waterway through the first outlet.

Zhu Shun asked the craftsmen of the cement factory to directly use the sand used in the concrete to build a river sand factory by the Chaohe River, using the river sand that was everywhere.

As the river rushes past, a sparkling stream of water makes a beautiful arc from the water tower through the ore factory and finally into the tide river.

After a month and a half of urgent exploration, the blasting team has preliminarily mastered fixed-point blasting, and a large amount of gunpowder has been buried at the blasting point calculated by measurement.

All the craftsmen of the demolition team withdrew to a safe distance, and the steward of the demolition team lit the fuse with his own hands.

"Boom! Rumble! ”

After a burst of explosions, a large amount of dust filled the vicinity of the gypsum mine, and a large piece of ore was obviously missing from the mine's mountain, and a large amount of ore fell under the mountain.

When the ore had almost fallen, hundreds of craftsmen wearing rattan hats began to pick the ore and transport the gypsum ore through the waterway to the crushing group downstream of the waterway.

In the homes of two uncles and one of the marquis, there are also some mines, and they often go to inspect the mining situation of the mines.

Craftsmen generally use human pounding to extract ore little by little, and when have they ever seen such a mining method.

The two words that Zhu Shun had said immediately came to mind.

Simple, brutal.
