Great warships

Chapter 20 Steel for Shipbuilding
Hearing Qin Tao's words, Liu Minggang's expression became serious: "Production of steel for shipbuilding? The technology is not low. If the steel is not up to standard and the ship sinks, your Uncle Liu will go in."

The requirements for steel used in ships are very high. As far as the scrap steel they return to the furnace, it is no problem to make floor slabs, but it is difficult to build ships!
"This is originally marine steel." Qin Tao said: "The performance is very good. After you return to the furnace, as long as you strictly control the smelting quality, it will be fine. By the way, you still need to dig an expert from a large steel factory. .It's more sure."

Qin Tao knows how to build ships, but he doesn't know how to make steel. In other words, he only understands the principles and not too many details.However, he can definitely point out a general direction for Liu Minggang.

After finishing speaking, Qin Tao looked at the slipway again: "This is just the beginning for us. We will get more scrapped ships when we arrive. Ship breaking will become a main task of our Mingzhou Shipyard in the past ten years. karma, so..."

Qin Tao is drawing a cake for Liu Minggang.

Liu Minggang is a flexible mind, otherwise he would not have brought Mingzhou Iron and Steel Plant to life. If there is an opportunity to continue to develop, Liu Minggang will definitely not refuse.

However, it is precisely because he is very smart that it is impossible for him to be overwhelmed by Qin Tao's few words and invest huge sums of money in new machinery and equipment. He has to think carefully.

"More hulks?" Liu Minggang looked at Qin Tao.

"Yes, we have a special channel to get more scrapped ships, even scrapped warships. The quality of the steel is very high. After re-smelting, it can be used to build civilian ships. There is no problem at all." Qin Tao said: "Uncle Liu, the price of steel plates for shipbuilding is at least several times that of steel bars for construction?"

Liu Minggang nodded: "Yes, the profit is good, but the purchase of equipment is also a huge sum of money. Although our Mingzhou Iron and Steel Plant is already alive, in fact, there is not much money on the books. We want to purchase The equipment requires a large loan from the bank, which is not a small risk."

"Uncle Liu, there are risks to be rewarded. Didn't you take a lot of risks when you led the steel plant out of the predicament? What about your daring spirit back then? When you start a business, don't just look at the current profits. , It depends on the future development!"

"Director Qin, your son is amazing. He can speak well and almost convinced me." Liu Minggang said, "Let's finalize the matter of scrap steel first. As for the matter of producing steel plates, let's talk about it later!"

Qin Tao smiled. He knew that Liu Minggang was not someone who could do it with a hot head. He just planted a seed for him today, and it will slowly germinate and grow up in the future.

"I think the removed steel plates are almost enough for a car." Liu Mingang continued, "Director Qin, I'll call a tractor and take the removed steel plates away."

"It's easy to say, just pay in cash." Qin Baoshan said.

The contract with the Yellow River Water Bureau has not yet officially come into effect, and the other party's down payment has not yet been made. Now, the oxygen and acetylene used to cut steel plates are all on credit, and the scrap steel for the first car can be paid in cash.

"No problem at all."

Soon, a tractor drove over and stopped at the pier, and the crane beside it directly hoisted the scrap steel onto the tractor.

Qin Tao commanded from the side: "Only the hull steel that has been dismantled, and those flanges and the like, are all good things for me!"

The scrap steel sold for ship breaking is ordinary hull scrap steel. Many things in the ship are of higher value, ranging from small flanges to large engines and propellers. Qin Tao also plans to use these wastes, no Will give it to Liu Minggang.

"Stingy!" Liu Ming just cast a glance at Qin Tao.

A load of scrap steel was pulled away. After arriving at the steel factory, Liu Minggang didn't ask someone to throw them into the steelmaking furnace. Instead, he picked up one of them, put it in a leather-made handbag, and then went straight to Huating No. [-] The steel plant, which is the largest steel plant in the entire region, was restructured a few years later and Baosteel Group Corporation was established.

"Brother Jun, help me test the internal element composition of this scrap iron, and estimate how strong the steel produced after being returned to the furnace and hot-rolled into steel plates can achieve?" Liu Minggang said in the Zhaoji restaurant outside the steel factory. Here, he invited his little boy Wang Jun to eat, and after eating and drinking, he took out a piece of scrap steel the size of a palm.

Liu Minggang and Wang Jun grew up together. Wang Jun had good grades in his studies. Later, he took a technical secondary school. After graduation, he was assigned to Huating No. [-] Iron and Steel Plant. After a few years, he entered the inspection department of the factory.

"Why, I'm not satisfied with making steel bars, but want to make steel plates? It's not easy..." Wang Jun took over the scrap steel while talking.

It was cut with an oxyacetylene flame, so its edges are all iron slippery, the surface is rusty, and it looks very shabby.Wang Jun shook his hand, then took out a folding fruit knife from the key chain around his waist, and then slashed it down.

A scratch appeared on the rusty surface, from shallow to deep.

"Not good!" Wang Jun exclaimed.

"what happened?"

"The tip of my knife!"

Wang Jun looked at his fruit knife made of high-carbon steel in the factory with distress. The tip of the knife was actually blunt. Then he looked at the white metallic luster from the inside of the scratch on the steel plate. He couldn't help but sigh with emotion: " This should be D-grade steel, where did you get it?"

"Scrap steel obtained from ship breaking." Liu Minggang said, "We want to use it to smelt and then hot-roll steel plates, and then use it to build ships..."

"Well." Wang Jun frowned: "In principle, there should be no problem. But, the technology of your factory... Forget it, I will work the night shift today, and I will take time to test the ingredients for you, and tomorrow morning can give you results."

"Thank you very much." Liu Minggang was very happy.

In principle, there is no problem, as long as an old skilled worker is dug from a large iron and steel plant. After all, the workers in the Mingzhou Iron and Steel Plant are all half-way monks, and the probability of producing slag is much higher than that of finished products. Unreliable.

the next day.

"This is not ordinary low-carbon steel, but alloy steel, doped with chromium." Wang Jun handed a list to Liu Minggang: "According to various test data, it is certain that this is the island country's WEL- TEN780C marine steel, the quality is quite good. It is generally used to manufacture high-end civilian ships."

"It seems that it should be no problem to reuse the steel for ships after hot rolling," Liu Mingang said.

"Yes, but on the one hand, you have no technology and on the other hand, you have no funds... By the way, does the Mingzhou Iron and Steel Plant have a large amount of blast furnace slag?" Wang Jun suddenly remembered something: "A few days ago, there was an island country The businessman who came to our steel factory to buy blast furnace slag, the price he gave is not low, I will give you his phone number in Huating Hotel, he should not have left..."
