Raw material preparation: Raw materials are mainly hot metal and scrap steel, which are sent to the smelting furnace after pretreatment.
Smelting: smelting in the converter or open furnace, by adjusting the furnace temperature and adding the appropriate amount of alloying elements, to obtain the requirements of the molten steel.
Continuous casting: molten steel is continuously cast into billets through a continuous casting machine, which ensures the dimensional accuracy and surface quality of the billets.
Hot rolling: The billet is heated in the heating furnace to about 1200°C to 1300°C, and after obtaining the required plasticity, it is rolled into the hot mill. In the process of hot rolling, the billet goes through rough rolling and fine rolling, gradually reducing the thickness and improving the shape and dimensional accuracy. At the same time, by controlling the cooling rate, the appropriate microstructure is obtained, which affects the hardness and toughness of the steel strip.
Winding: the hot rolled steel strip is rolled into a coil, which is convenient for subsequent processing, storage and transportation.
Inspection: Strict quality inspection of the Q235 carbon steel strip is carried out, including chemical composition analysis, mechanical property testing and surface quality inspection, to ensure that the product meets the national standard.
Construction field: In the construction field, Q235 carbon steel strip is often used to make steel structure projects, such as Bridges, towers, components, etc. Its high strength and excellent corrosion resistance can effectively improve the wind pressure resistance and service life of buildings.
Machinery manufacturing: In the field of machinery manufacturing, it is widely used in the manufacture of various parts and structural parts, such as welded structures, bolted structures, etc. Its good plasticity and weldability make it the material of choice for the manufacturing industry.
Vehicle manufacturing: In the field of vehicles, this steel belt can also manufacture the body, frame, chassis and other components of cars, trains, ships and other vehicles. Its high strength and wear resistance help to improve the service life and safety performance of vehicles.
Other fields: In addition, it can also manufacture pipes, containers, storage tanks, etc., and as a raw material for welded steel pipes.
