Advantages

(1) Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation.

(2) Hot rolling can improve the processing performance of metals and alloys, that is, the coarse grains in the casting state are broken, the cracks are healed significantly, the casting defects are reduced or eliminated, the cast structure is transformed into deformed structure, and the processing performance of the alloy is improved.

(3) The hot rolling usually adopts large ingot and large pressure rolling, which not only improves the production efficiency, but also creates conditions for improving the rolling speed and realizing the continuous and automatic rolling process.

Automotive steel is mainly composed of sheet steel and special steel, with high strength, thin specification and corrosion resistance, high production technology. Compared with ordinary steel such as construction steel, automotive steel belongs to high value-added products, mainly reflected in the following aspects:

(1) High technical content. With the continuous improvement of the level of automotive products, the requirements for automotive steel are also increasing day by day. First of all, in order to reduce the weight of automotive products, save materials, reduce fuel consumption, reduce costs, and improve safety standards, it is necessary to use high strength and thin specification steel. Secondly, in order to improve the anti-corrosion performance of automobile products, prolong the service life of the automobile, it is necessary to improve the surface treatment technology of the automobile inside and outside the plate, such as the use of galvanized sheet or alloy galvanized sheet.

(2) Advanced production equipment, high level of production technology. The production of automotive steel requires the use of advanced production equipment, so the scale of investment is relatively large, and from investment construction to completion and production, to fully achieve the design of production capacity generally needs about 5 years. In addition, due to the high requirements for the production process, there are also high requirements on the level and structure of the production personnel.
