热轧酸洗涂油板是汽车业需要的新钢种，其较好的表面质量、厚度公差、加工性能，可以替代车身覆盖件和以往用冷轧板生产的汽车零部件， 由此降低原材料成本10%左右。随着经济的发展，汽车的生产也大幅增加，板材的使用量不断提高， 国内汽车行业许多车型的零部件原设计要求使用热轧酸洗板，如：轿车的副车架、车轮轮辐、前后桥总成、卡车箱板、防护网、 汽车大梁以及零配件等，由于国内热轧酸洗板的供应不足，汽车厂一般用冷板或热板代替或自行酸洗。与热轧板相比， 热轧酸洗板具有许多优点：是表面质量，其表面质量非常好，因为热轧酸洗板去除了热轧板表面的氧化层并提高了钢。 材料的表面质量极大地方便了使用者的涂漆和焊接;第二个是尺寸精度和平整度。热轧酸洗板的尺寸精度非常高，在压平后， 可以对热轧酸洗板进行一些改变，从而减少偏差;第三热轧酸洗板表面外观非常好，外观相对美观;第四，购买者不需要腌制自己以避免对环境进行净化。 Hot-rolled acid washing and coating oil plate is a new steel type needed by the automobile industry. Its good surface quality, thickness tolerance and processing performance can replace the body cover parts and the automobile parts produced by cold rolling plate, thus reducing the raw material cost by about 10%.With the development of economy, the automobile production also increased significantly, the use of plate increasing, the domestic automobile industry many models of parts of the original design requirements use hot rolled pickling plate, such as: car subframe, wheel spoke, front and rear axle assembly, truck box plate, protective net, car girder and parts, due to the domestic hot rolled pickling plate supply, automobile factory generally with cold plate or hot plate instead or self pickling. Compared with the hot rolled plates, the hot rolled pickling plate has many advantages: the surface quality, and its surface quality is very good, because the hot rolled pickling plate removes the oxide layer of the hot rolled plate surface and improves the steel. The surface quality of the material greatly facilitates the user's painting and welding; the second is the size accuracy and flatness. The size accuracy of the hot rolled pickling plate is very high, and the hot rolled pickling plate can be leveled to reduce the deviation; the third hot rolled pickling plate has a very good appearance and relatively beautiful appearance; fourth, the buyer does not need to pickle himself to avoid purifying the environment.
