Hegang Hangang: seizing the opportunity to make excellent electrical steel
Since the beginning of this year, Hegang Handan Iron and Steel Co
, Ltd
has seized market opportunities, continuously optimized the product structure of Hanbao production line, took the development of electrical steel as a new efficiency growth pole, actively promoted the coordination of production, marketing and research, quickly opened the domestic electrical steel market, and won the recognition of well-known electrical steel deep-processing enterprises
In the first seven months, the electrical steel of Hanbao production line has grown from scratch, 10 electrical steel customers have been developed, the monthly production and sales volume has increased from the initial 1000 tons to 22000 tons, and the cumulative supply is 58000 tons

At the beginning of this year, the market price of domestic electrical steel rose all the way, and the market demand and profit margin increased
The company accurately caught the market demand, quickly adjusted the product structure of Hanbao production line, established an electrical steel production and marketing research team, and actively carried out electrical steel R & D and market expansion
It took half a year from the monthly production and marketing of 1000 tons in February to the maximum monthly production and marketing of 22000 tons, which made the company's electrical steel recognized in the domestic market and won a reputation

Accurate connection and successful development of well-known electrical steel customers
“ The electrical steel produced by your company has excellent properties and fully meets our needs for processing silicon steel sheets
Using your products, we can rest assured that we will continue to increase the order quantity in the next step& rdquo; On August 9, when Zhang Junli, the customer manager of electrical steel products of the automotive home appliance board division, paid a telephone return visit to Zhongsheng metal plate and strip Technology Co
, Ltd
, the customer representative highly recognized the company's electrical steel products

The customer is the largest private electrical steel plate manufacturer in China and the first electrical steel customer developed by the company this year& ldquo; The reason why we choose to develop Zhongsheng metal first is that we pay attention to its popularity, which is convenient for us to quickly open the domestic electrical steel market& rdquo; Zhang Junli said

Everything is difficult at the beginning
Zhang Junli clearly remembers the arduous process of visiting and docking Zhongsheng metal
At the beginning of the year, Zhang Junli closed the door for his first visit to customers
As a new force in the electrical steel market, customers do not understand or trust the company's products
After listening to Zhang Junli's introduction, they politely refused cooperation
However, Zhang Junli was not discouraged
After that, he visited twice
Moved by patience and sincerity, the customer finally agreed to try it out

Subsequently, Zhongsheng metal officially issued a trial contract of 500 tons of hbw800 and hbw1300 non oriented electrical steel to the company for the manufacture of silicon steel sheets
Due to the large order quantity of customers and the tight delivery time, it has brought great challenges to the production organization of Hanbao production line

Contracts are orders! Led by the automotive appliance board business department, the production plan is jointly agreed with the production, technology and quality departments of the company
The hot plate R & D team of the technology center quickly strengthened the technical connection with the technical personnel of the customer through telephone, network, video conference and other online methods, understood in detail the performance requirements of the electrical steel required by the customer, and optimized and designed a new process scheme from the aspects of establishing continuous casting solidification model, optimizing slab sizing, slab heating strategy, rolling specification transition and so on, And detailed production guarantee measures

Hanbao production line stepped up the production under the contract
Technicians focused on the production line throughout the whole process, and cooperated efficiently in production, shipping and other links
The overall steelmaking and hot rolling production was smooth, ensuring that the products were offline with high quality and delivered on schedule, and the indicators such as iron loss, magnetic properties and plate shape fully meet the needs of customers
After the trial of the first batch of products, the customer was very satisfied with the quality, and an additional contract of 2000 tons was added

“ Zhongsheng metal is a subsidiary of Guangdong Yima
Through deepening cooperation with Zhongsheng metal, we have successfully introduced electrical steel into Guangdong Yima& rdquo; Zhang Junli said excitedly
At present, the company has supplied 7500 tons of Guangdong Yima and Zhongsheng metal non oriented electrical steel

In the first seven months, the electrical steel marketing personnel of the automotive home appliance board division actively promoted the company's non oriented electrical steel products by strengthening market visits, successively developed 10 electrical steel customers such as Midea Group, Huangshi Shanli, Jiangxi juhuang and Zhejiang Jindian, with a cumulative supply of 58000 tons

System tackling key problems to promote double improvement of product output and quality
“ The qualified rate of 175 rolls of non oriented electrical steel hbw800 produced today reached 98
9%
This is the fifth time in a row that the qualified rate of the surface has exceeded 98%
The problem of foreign matters on the surface has been effectively solved
Relevant measures should be solidified into subsequent production& rdquo; At 17:00 on August 6, in the quality inspection operation room of Hanbao hot rolling plant, Zhang Zhiqiang, leader of the electrical steel R & D team of the technical center, told Li Aimin, a technician of Hanbao hot rolling plant, after recording the surface inspection data of the electrical steel produced this time

Since the beginning of this year, aiming at the growth opportunity of electrical steel market demand, the company has quickly established an electrical steel R & D team
Through in-depth connection with customers, combined with the actual situation of Hanbao production line, the company has innovatively designed the process scheme and organized the production of the whole process in a fine manner, and completed the non directional electrical steel hbw600 & mdash in just two months; Development, trial production and mass production of hbw1300

Due to the special composition system of electrical steel and the significant differences in high-temperature physical properties between electrical steel and other products, the pressing of foreign matters on the surface during hot rolling has always been a common problem in the electrical steel industry& ldquo; It has a serious impact on the post process cold rolling, which is prone to surface holes, rolling breakage and other defects, increases the risk of belt breakage, not only increases the production cost, but also affects the product delivery speed, which gives us a headache& rdquo; Zhang Zhiqiang said

In order to completely solve the problem of foreign matter pressing into the surface, the electrical steel R & D team of the technical center carried out special research
Zhang Zhiqiang led the delegation members Li Bin and Liu Fenglin to take root in the production line every day, record the morphology, size and distribution position of each defect in the leveling process volume by volume *, then take samples for microstructure observation, carefully arrange the on-site equipment that may lead to the defect, and finally find out the cause of the defect

Subsequently, the R & D team and Hanbao hot rolling plant analyzed and formulated a series of key improvement measures from finish rolling to coiling process, so that the foreign matter pressing defects were effectively controlled, and the genuine product rate of electrical steel was increased from the initial 75
9% to more than 98
3% at present

Starting from the production of electrical steel in Hanbao production line, high-quality and efficient production process has been regarded as the key research topic of electrical steel R & D team
The R & D team, together with Hanbao hot rolling plant and cold rolling plant, aimed at the problems existing in production, such as poor molten steel castability, large fluctuation in rolling crown control, various surface defects and complex causes, carried out systematic research, developed perfect research measures, and promoted the production of non leveling process of hot rolled non oriented electrical steel by finding gaps in standard advanced enterprises, * production problems, research and analysis, The production efficiency and product quality of electrical steel are effectively improved

 
“ In production, we have gradually formed and improved a series of technical schemes for electrical steel process, such as high cleanliness smelting of molten steel, high quality control of strip surface, high-precision regulation of cold rolling thickness, etc
At present, the magnetic properties, surface quality and dimensional tolerance of the products have reached the advanced level of the same industry in China& rdquo; Li Bin, a member of the electrical steel R & D team of the technology center, said proudly
