Products Description
Hot rolled steel is steel that has been roll-pressed at very high temperatures—over 1,700, which is above the re-crystallization temperature for most steels. This makes the steel easier to form, and resulting in products that are easier to work with. To process hot rolled steel, manufacturers first start with a large, rectangular length of metal, called a billet. The billet is heated and then sent for pre-processing, where it is flattened into a large roll. From there, it is kept at a high temperature and run through a series of rollers to achieve its finished dimensions. Steel shrinks slightly as it cools. Since hot rolled steel is cooled after processing, there is less control over its final shape, making it less suitable for precision applications. Hot rolled steel is often used in applications where minutely specific dimensions aren't crucial.
It is a flat sheet of steel made by pouring molten steel, cooling and pressing.
The steel plate is divided according to thickness, the steel plate <4 mm (the thinnest 0.2mm), medium thick steel plate 4-60 mm, extra thick steel plate 60-115 mm.
The steel plate is divided into rolling, hot rolling and cold rolling.
The width of the sheet is 500~3000 mm;
The thick width is 600~3000 mm.
There are common steel, high quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet.
According to professional use, there are oil barrel board, enamel board, bulletproof board and so on;
According to the surface coating layer, galvanized sheet, tin plate, lead plate, plastic composite plate.

Mechanical Properties
Carbon steel manufacturing process:
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.
Application of carbon steel:
Carbon steel, carbon tool steel, spring steel and all kinds of waste materials with carbon content of 0.1%-1.2% can be used as metallurgical steel carbon and carburizing steel materials. The following points should be noted when choosing carbon steel return material.
1. Steel ingot riser, hot rolling forging cutting head, etc., in which the content of phosphorus and sulfur is higher. The dosage should be controlled when smelting low phosphorus and sulfur alloy steel.
2. The components of scrap, waste wire and strip, waste steel and so on are not accurate. The selection should be careful, and it is best to use after remelting (washing furnace).
3.The use of carbon steel scrap steel should be carried out spark identification, classification use.
