S355jr hot rolled steel coil plate sheet
Introduction
Steel plate delivery state is hot rolled, grade decomposition S is a structural steel, 355 is the yield strength of the steel plate is not less than 355MPa, JR represents the delivery quality of the steel plate, JR does not do the impact, corresponding to the national standard B, B does not do the impact, and later changed to the impact of the ambient temperature, 20 degrees of impact.S355JR by the converter or the electric furnace refining of the steel belongs to the sedentary steel.
S355JR steel plate production process and procedure
The production process of S355JR steel plate mainly includes steps of steelmaking, continuous casting and rolling.
Steelmaking is carried out through converter or electric furnace, adding appropriate amount of alloying elements to adjust the chemical composition of steel to meet the performance requirements of S355JR. Then, the refined steel is continuously cast to form steel plate or billet. Finally, the continuous casting steel plate or billet will be rolled, through multiple rolling passes and temperature control, to obtain the required thickness, width and length of S355JR steel plate.
S355JR steel plate is widely used in construction, machinery, ships, bridges, chemical industry, petroleum, electric power and other fields because of its excellent performance.
In the field of construction, S355JR steel plate is commonly used in the production of structural parts such as high-rise buildings and large industrial plants.
In the field of machinery, it is used to make various equipment shells, brackets and other structural parts.
In bridge engineering, S355JR steel plate is widely used because of its high strength and good durability.
In addition, S355JR steel plate can be used in chemical, petroleum, electric power and other industries to make various storage tanks, pipelines, reactors and other equipment to withstand high temperature, high pressure, strong corrosion and other harsh conditions.
