The hot rolling technolodge of welding of nm400 steel sheet
The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the welding of NM400 steel sheet steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of welding of NM400 steel sheet extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.
Wear resistant steel plate welding of NM400 steel sheet is widely used in engineering, mining, construction, agriculture, cement production, port, electric power, metallurgy and other mechanical products, which require high strength and wear resistance. Such as bulldozers, loaders, excavators, dump trucks and various mining machinery, grab, stacker reclaimer, conveying bending structure, etc. The wear resistant steel plate welding of NM400 steel sheet can obtain good combination of strength and toughness through scientific quenching and tempering process, which can also improve the steel hardness to achieve the purpose of wear resistantance.
The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.
If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
