多年来钢铁工业的发展有效支撑了我国国民经济平稳较快发展，热轧板产量和质量的提升也较好地满足了我国建筑、机械制造等行业不断增长的实际需求。

Over the years, the development of iron and steel industry has effectively supported the steady and rapid development of China's national economy, and the improvement of the output and quality of hot rolled plate has also well met the growing actual demand of China's construction, machinery manufacturing and other industries.

板带钢又可称为板带材，它是通过平辑轧机轧制而成的断面为扁矩形具有较大宽厚比的一种轧材，一般采用单张供货或成卷供货。按不同的分类标准，板带材具有多种特定的称谓。

Plate strip steel can also be called plate strip, it is through the rolling mill rolling section for the flat rectangle with a large width and thickness ratio of a rolling material, generally using single supply or volume supply.According to different classification standards, plate and strip materials have a variety of specific titles.

热轧材按断面形状分类，可以分为板带材、管材、型材及特殊断面材等。不同轧材的生产需要不同形式的生产设备及采取不同的工艺，所用轧机各有特点。一般用于生产型材的轧机，轧辊上都有孔型，轧件在经过轧机轧制后，要根据产品的类型、材质和性能要求不同进行不同的轧后冷却控制，以得到符合标准的产品。

Hot rolled materials are classified according to the section shape, and can be divided into strip, pipe, profile and special section materials.The production of different rolling materials requires different forms of production equipment and adopts different processes, and the rolling mill used has its own characteristics.Generally used in the production of profile rolling mill, there are holes on the roll, rolling parts after the rolling mill rolling, according to the product type, material and performance requirements of different post-rolling cooling control, in order to get the products that meet the standards.

热轧板的机械性能虽然不及冷轧钢板，也次于锻造加工，但有较好的韧性和延展性。热轧的终止温度一般为800~900，之后一般在空气中冷却，因而热轧状态相当于正火处理。热轧状态交货的金属材料，由于表面覆盖有一层氧化膜，因而具有一定的耐蚀性。而且热轧精整卷若经酸洗去除氧化皮并涂油后即成热轧酸洗板卷。该产品有局部替代冷轧板的趋向，价格适中，所以深受广大用户喜爱。

Although the mechanical performance of hot rolled plate is not as good as cold rolled steel plate and secondary to forging processing, it has good toughness and ductility.The termination temperature of the hot rolling is generally 800~900, and then it is generally cooled in the air, so the hot rolling state is equivalent to the normal ignition treatment.The metal material delivered in the hot rolled state has an oxide film because the surface is covered, and thus has certain corrosion resistance.And if the hot rolled fine whole coil after pickling to remove the oxide skin and apply oil after the hot rolled acid washing plate coil.The product has a local replacement of cold rolled plate trend, the price is moderate, so loved by the majority of users.
