For QStE260N structural steel sheet, automobile steel sheet materials, it must have excellent pressure-bearing performance. Automobile steel sheets of substandard quality are prone to fracture problems, which also cause waste and consumption of production materials, and directly increase the production cost of automobiles. Generally, the qualified automobile steel sheets used in automobile manufacturing are high-strength steel plates. The high-quality automobile steel sheets are more durable and improve the quality of the entire automobile.
In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and QStE260N structural steel sheet pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
Standing at a new historical starting point, we adapt to the requirements of supply side QStE260N structural steel sheet structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading QStE260N structural steel sheet steel materials supplier.
Application of medium and thick plates: Medium and thick plates are used for construction engineering, machinery manufacturing, shipbuilding, bridge construction, etc. Medium and thick plates QStE260N structural steel sheet can also be used to manufacture various containers, furnace shells, furnace plates, some parts of tractors and welding components. Medium and thick plates are usually in form of bridges and automobile static steel plates, low alloy steel plates, shipbuilding steel plates, boiler steel plates, pressure vessel steel plates, checkered steel plates, automobile girder steel plates, etc.
