What is the use of carbon steel coil

Compared with ordinary building boards, carbon steel coils have stronger scratch resistance, and are not easy to leave scratches after being scratched by sharp objects, so they are often used to make home appliances and rolling shutter doors and windows. It is flexible and easy to form, and is often used as a substitute for wood.

How to polish carbon steel coil

1. When polishing carbon steel coils, you can use mechanical polishing. This method is generally manual, which is to flatten the concave and convex positions of the steel coils. In the process, props such as sandpaper and whetstone bars will be used. Mechanical polishing of the coil can improve the surface quality of the steel coil.
2. When polishing carbon steel coils, chemical polishing can also be used. This polishing method uses chemical reactions to flatten the convex position of the steel coils. The biggest advantage is that there is no need to use too much in the process. Overly complex equipment, and the polishing effect is good.

3. Electrolytic polishing can also be used for carbon steel coil polishing. Although the principle is very similar to that of chemical polishing, the polishing effect of electrolytic polishing will be better, because this polishing method is the point of use. The solution will flatten the raised position on the surface of the steel coil.

What should be paid attention to when transporting color-coated rolls

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.
