Carbon steel coil is also known as low or high carbon steel plate and HRC coil, characterized by complete specifications,diverse materials; High dimensional accuracy, up to ± 0.1mm;Excellent surface quality, good brightness; Strong corrosion resistance, high tensile strength and fatigue strength;
Stable chemical composition, pure steel, low inclusion content, widely used in construction, shipbuilding, vehicle manufacturing, machinery manufacturing, furniture and household appliances industry, electrical and automation industry.
The smelting of carbon steel is usually carried out in converter and open hearth. Converters generally smelt ordinary carbon steel, while open furnaces smelt all kinds of high-quality steel. The technology of oxygen top blow converter is developing rapidly and it can replace open hearth furnace. The refined liquid steel is injected into the ingot mold to obtain various ingot. After the ingot is forged or rolled, it is processed into plates, strips, bars, and sections of various sectional shapes. Carbon steel is usually used directly in the hot rolled state. When used for manufacturing tools and various machine parts, it needs to be heat treated according to the requirements of use; As for steel castings, most of them are heat-treated.
