Product Description
Description:The main working parts and tools on a rolling mill that cause continuous plastic deformation of metals.The use effect of the roll in the rolling mill depends not only on the material of the roll and its metallurgical quality, but also on the conditions of use, roll design, operation and maintenance. The operating conditions of the rolls of different types of rolling mills are very different, and the factors that cause the difference are:1) rolling Mill conditions. Such as rolling mill type, rolling mill and roll design, pass design, water cooling conditions and bearing types;2) Rolling conditions such as the variety, specification and deformation resistance of the rolled material, reduction system and temperature system, output requirements and operation, etc.;3) Requirements for product quality and surface quality, etc.Our company company is equipped with a complete production process and advanced production and testing equipment, which fundamentally ensures the high quality of the rolls and meets the rolling characteristics and technical requirements of various rolling mills.Application:Various types of metallurgical rolls used for modern hot strip continuous rolling mills, medium and wide plate rolling mills, and various types of steel, bar, high wire, medium and narrow strip millsspecification:Chemical AnalysisDesignation of rolls | Material code | C | Si | Mn | Ni | Cr | Mo |
