Privilege Metallurgical Technology provides cutting-edge technology for carbon reduction and carbon neutrality in the steel industry!
Today, the metallurgical industry is focusing on green, low-carbon, intelligent and safe production, and metallurgical technology companies continue to move in the same direction, as Italian steelmaker Avedi has achieved a major milestone by achieving net-zero CO2 emissions at its Italian plant, 28 years ahead of the European Commission's decarbonization target of 2050.
1500mm wide strip successfully rolled at one time by Bayuquan Branch of Angang Steel
Faced with the severe situation of the current steel market, the hot rolling department of Bayuquan Branch of Angang Iron and Steel Co., Ltd. can not rely on each other. While implementing the deep limit cost reduction, it has also explored the internal potential and explored the research and development of limit specification products. After breaking the design limit of 1430mm wide strip, it has recently refreshed the product width limit again, achieving a successful rolling of 1500mm wide strip at one time, making new breakthroughs in product specifications and leading the similar production lines in the same industry in China.
Three Hot Aluminizing Processes for Steel Wire
According to the different ways of wire surface purification and activation, there are three hot aluminizing processes for steel wire.
What material does manganese steel belong to? Which is better, manganese steel or stainless steel?
High manganese steel is a common steel in industry. The hardness of high manganese steel is very high. It is often compared with high manganese steel and high carbon steel. Some people doubt that high manganese steel knife can cut iron. What is the difference between high manganese steel and 304 steel?
North China galvanized strip steel is steadily rising. Tangshan Shengfang is at a standstill
Today, the galvanized strip steel market in North China is steadily rising. Tianjin Haigang was up 50 yuan to 5700 yuan/ton compared with yesterday, Shengfang Jinghua was stable at 5560 yuan/ton compared with yesterday, and Tangshan Xifeng was stable at 5490 yuan/ton compared with yesterday. According to the monitoring feedback of Lange Iron and Steel Network, the galvanized strip steel market in Tangshan is currently at a standstill due to the impact of epidemic prevention and control. The galvanized strip steel processing enterprises in Tangshan have been fully closed down, and employees have conducted closed management and cooperated with nucleic acid detection in the community. In addition to the order inventory in the factory and warehouse, the remaining inventory of the seven galvanized strip steel processing enterprises participating in the survey is about 120000 tons, and the daily output is about 12300 tons, which is significantly lower than last week. At the same time, because Shengfang is still under the control of the whole region, the supply of main galvanized strip steel producing areas in North China has decreased significantly. Although some upstream Tangshan strip steel traders have quoted prices, few deals have been concluded. Shengfang area is still closed. In Tianjin, due to the control of Tang and Sheng, part of the demand has shifted, and the turnover of orders and transactions is better. It is expected that the market for galvanized strip steel in North China will be dominated by narrow shocks tomorrow. (Lange Steel)
Strip C warpage adjustment method
In the rolling process, the compression deformation of the strip steel along the width direction is uneven, which will produce problems such as waveform, buckling, C-shaped warping, etc., making the strip steel lose its straightness. Among them, the c-type warping is caused by the different extension of the upper and lower surfaces of the strip steel in the width direction. The upper surface has a larger extension, and the lower surface has a smaller extension, which is downward c-shaped warping; Otherwise, it is upward c-warping.
The first 850mm full continuous rolling strip production line in Ningxia has entered trial production
On January 26, the first roll of strip steel was successfully rolled off the line at the 850mm full continuous hot strip production site of Ningxia Jianlong Steel Rolling Plant, marking that the first 850mm full continuous hot strip production line in Ningxia officially entered the trial production stage, and moved forward to achieve production and efficiency.
The working environment and material selection of continuous annealing furnace for strip steel
For the tower furnace heating chamber lining generally with lightweight clay brick 230mm and adiabatic brick 70116mm masonry. That is, high temperature resistance, adiabatic effect and good. In order to ensure its stability, along the height direction should be segmented with metal beams to hold, and in each segment between the expansion interval. The lining of the conservatory is the same as that of the heating room. Slow cooling room cooling method, rely on radiation tube in the non-heating air to fast cooling, some rely only on the brick layer cooling to cooling, some set up a special cooling duct, slow cooling room lining with 12015Omm adiabatic brick.
"5G+machine vision" helps Angang steel strip inspection
Wang Xianfeng, a reporter from China Economic Herald, China Development Network, reported that recently, the "5G based machine vision strip surface inspection platform" project was applied in the cold rolling plant of Angang Steel, which not only realized distributed, long-term, stable, online identification and storage of strip surface defect information, but also realized subsystem data sharing. Each system can bring more than 1.8 million yuan of economic benefits to users every year.
