Process of hot rolled steel

Continuous hot-dip galvanizing of hot-rolled steel strip is a new process for the production of hot-dip galvanized sheet. The application of this process greatly improves the efficiency of steel strip production and is of great significance for ensuring the quality of steel strip. The production of continuous hot-dip galvanizing of hot-rolled steel strip originated in Japan in the 1970s. This technology is an important innovation to improve the production technology of steel strip. Under the background of people's higher and higher requirements for the quality of hot-dip galvanized sheet, strengthening hot-rolled steel The study of continuous hot-dip galvanizing technology has become an inevitable choice for iron and steel enterprises.

In the decades of development, the production technology of continuous hot-dip galvanizing of hot-rolled steel strip has been developed to varying degrees, but many problems have also accumulated. Solving these problems is to improve the technical level of continuous hot-dip galvanizing of hot-rolled steel strip. inevitable choice. In the increasingly fierce competition in the steel strip market, if iron and steel enterprises want to achieve their own long-term development, they must strengthen the research on the production technology of continuous hot-dip galvanizing of hot-rolled steel strips and realize the innovation of continuous hot-dip galvanizing of hot-rolled steel strips.

What kind of performance does carbon steel coil have

The concept of cold rolling and hot rolling

Although stainless steel plates account for a relatively small proportion of world steel consumption, they are still vital to specific manufacturing industries such as the energy and food processing markets. At present, the global consumption of stainless steel plate materials is continuously increasing.

Production process of welded steel pipe

The development of steel pipe production technology began with the rise of bicycle manufacturing, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry, and The drilling and transportation of oil and natural gas have strongly promoted the development of the steel pipe industry in terms of variety, output and quality.

Steel prices have risen by more than a thousand steel companies generally turn losses into profits

Since the first half of last year, steel prices have begun to recover thanks to a series of measures such as supply-side reforms and elimination of backward production capacity. Taking rebar as an example, the average price on March 9 last year was 2475 yuan/ton, and on March 9 this year, it has risen to 3852 yuan/ton, an increase of 35%.

China Steel Association: Steel prices in the domestic market continued to rise slightly in September

According to data from the China Iron and Steel Association, in September, the domestic steel market demand was strong, and steel prices continued to rise. Affected by the rapid release of steel production capacity, pressure on the supply side has risen, and the price increase of steel has narrowed.
