目前提高板材质量的途径有以下几方面。 在完善轧机结构方面,国外一些公司是在现有四辊轧机的基础上改造成新颖的不同结构形式的六辊或五辊轧机,其主要特点是增设液压装置,使其能够借助于轧辊的弯曲或水平移动或二者综合使用,生产出尺寸精度高和必要形貌的钢板,同时还能提高轧机的生产率。实施这些方案,通常是更换老设备 The current ways to improve the quality of sheet metal in the following areas. In improving the mill structure, some foreign companies are based on the existing four-high rolling mill into a novel structure of the six-roller or five-roll mill, the main feature is the addition of hydraulic devices, which can make use of the roll bending Or horizontal movement or a combination of both to produce a steel plate with high dimensional accuracy and the necessary topography while also increasing the mill’s productivity. These programs are usually implemented by replacing old equipment
