With the record refresh of the slab heating capacity of the No. 3 furnace repair cycle to 7,000 tons, the magnesium oxide-chromium oxide oriented silicon steel protective coating developed by Zhao, Ma and Zhou's research group has a certain patent value.

It's hard to say what the value of this patent will be.

Oriented silicon steel protective coating is used in the firing of oriented silicon steel, if the brother steel mill can not even make oriented silicon steel, then this protective coating is of no value to the brother steel mill for the time being.

That is to say, the patent scope of use of this coating is relatively narrow, and only one brother steel mill in China may need it, and the international iron and steel companies are not sure for the time being.

"Two, no matter what, we should first apply for a patent for our own coating. Zhao Qingshan made a suggestion.

"Yes, the sooner the better. "Ma Hanxing has done so many patent digestion topics, and he understands patent things.

Zhou Tienan is self-aware, he said calmly: "The substantive invention work of self-developed coatings is almost all done by Zhao Qingshan, and the first inventor must have written Zhao Qingshan's name." ”

Ma Hanxing nodded and said, "There is no doubt about it. ”

The most important first inventor was determined in an indisputable way, and Zhao Qingshan was slightly pleased, he said: "The second and third inventors should write the names of Ma Gong and Tie Nan, if there is no problem, then I will start writing the patent application?"

"Write it. ”

Zhao Qingshan worked hard to write the patent application, attached the summary report of the self-developed coating, and submitted it to the stock exchange for approval.

The institute approved all the way, and soon approved the director.

Director Qin praised it greatly: "Ye Guoguo said that you are three stinkers, no, you are three Zhuge Liang! Xiao Zhao, you work hard, and your future is immeasurable." The patent application will be applied for, relying on the big platform of Jianggang, you have unlimited room to play. ”

Director Qin is right, relying on the platform of central enterprises, even if a patent is applied, and there happens to be a company willing to spend money to buy a patent, it is still unknown whether the patent fee can be paid in full to the patent inventor.

The "1.7 meter rolling mill system" began to be installed and commissioned in the 70s, officially put into operation in 1980, and reached the approved design capacity in 1985.

In the past ten years, a large number of experts from West Germany and Dongying went to Jianggang to assist the "1.7 meter rolling mill system" to be put into operation as scheduled and reach the approved design capacity.

The "one-meter-seven rolling mill system" has reached the approved design capacity at the end of 85, and the experts from West Germany and Dongying have returned to China in 86.

A small group of foreign experts remained in China to see how the "1.7 meter rolling mill system" performed in 1986.

There are still a few days left in 1986 to end, and the dust has settled on all aspects of Jianggang.

The approved design capacity of the hot rolling mill is 3 million tons, and the plant has completed 3.09 million tons of hot rolled steel this year, exceeding the approved design capacity.

The equipment for the hot rolling mill is supplied by Nippon Steel Corporation, and the person who designed the equipment knows the equipment better than the person who uses it.

Goro Kinoshita, one of the designers of the No. 3 furnace of the hot rolling mill, saw the firing capacity of the No. 3 furnace increase from the initial few hundred tons to 2,000 tons, and then to 4,000 tons, and after adopting the protective coating developed by Nippon Steel, the capacity of the No. 3 furnace rushed to 5,000 tons in one fell swoop.

To Kinoshita's shock, in the past few months, Jianggang has developed a new silicon steel protective coating on its own, which, according to his investigation, is magnesium oxide-chromium oxide, which is completely different from Nippon Steel's silicon-silicon carbide.

Jianggang's self-developed coating was applied to the oriented silicon steel fired by the No. 3 furnace, which increased the heating capacity of the slab in the No. 3 furnace repair cycle to 7,000 tons!

Unbelievable!

Goro Kinoshita immediately reported to the headquarters: "According to my investigation, three engineers from the research institute of Jiangcheng Iron and Steel Company have recently successfully developed a new oriented silicon steel protective coating, which has increased the capacity of the No. 3 furnace of the hot rolling mill to an astonishing level of 7,000 tons!"

"In contrast, the silicon-silicon carbide series we developed should obviously be phased out. At present, the silicon steel production capacity of Jiangcheng Iron and Steel Company is only 70,000 tons, of which less than 50,000 tons of oriented silicon steel, while the silicon steel production capacity of several plants of our Nippon Steel is ten times that of them. ”

"The furnaces in their hot rolling mill are almost exactly the same as those in our Hikarata. I suggest that you obtain their self-developed coating patents at the lowest cost, please arrange business personnel to negotiate with them immediately, please!"

The next day, Nippon Steel technical expert Goro Kinoshita, business representative Kyosuke Irie, and an interpreter visited the Steel Research Institute.

Kinoshita-kun and Irie-kun are old friends of Jianggang, and they explained their intention to visit the three inventors of magnesium oxide-chromium trioxide coatings.

Director Qin smiled, I understand, I know what you want to do, then let's talk about it and pick up customers.

In the conference room of the Steel Research Institute, Chinese and Japanese personnel had a friendly conversation.

Kinoshita and Irie did not expect that the first inventor of magnesium oxide-chromium trioxide paint would be such a young Zhao Jun.

After some pleasantries, Irie said: "Let's get into the topic, we are eager to obtain the patent right to use the magnesium oxide-chromium trioxide coating developed by your company, and promise to keep it confidential for your company." ”

Before October 25, Jianggang has been using Nippon Steel's oriented silicon steel coatings, and the operation method is that Nippon Steel will license the patent use rights of silicon-silicon carbide protective coatings to Jianggang, charge a certain patent fee, and Jianggang Coking Plant will produce silicon-silicon carbide protective coatings and apply them to the production of hot rolling mills.

Objectively speaking, Irie is an honest business negotiator, and he suggested that China and Japan adopt the same business cooperation method, and that Jianggang would license the patent right to use magnesium oxide-chromium trioxide paint to Nippon Steel, and Nippon Steel would pay a reasonable patent fee.

"No problem. Zhao Qingshan readily agreed to this kind of mutually beneficial and win-win, coming-and-going, and long-term cooperation.

"Agreed. Of course, Director Qin would not object, not only did he not object, but he was even a little excited.

For a long time, patents have been transferred or authorized to us by people from East and West Germany. Now, Dongying people have come to the door and begged us to authorize the patent to them.

A major breakthrough!

Director Qin smiled and said, "Translator Xu, you ask Mr. Irijiang, what kind of price are they willing to offer?"

Mr. Irie said with certainty, "$100,000." ”

$100,000...... Ma Hanxing's palms were dripping with sweat.

Nippon Steel's silicon-silicon carbide patent was licensed to Jianggang for a patent fee of US$70,000.

The self-developed magnesium oxide-chromium trioxide system developed by Jianggang is applied to the same silicon steel and the same furnace, which increases the capacity of the furnace from 5,000 tons to 7,000 tons. This can be roughly understood as a 40% improvement in coating performance.

You get what you pay for, and Mr. Irie quoted a price of $100,000, and he was very sincere.
