高强度高精度高刚度38辊辊系冷轧机

High strength and precision stiff 38 roll system cold rolling mill

Abstract

本实用新型38辊辊系冷轧机,如附图所示38支辊分上下各19支两组分别安装在外形如同常规大型轧机机架的刚性支架盒上;工作辊长度与直径比65—80倍;背衬轴承与工作辊的直径比为15倍;相接触辊的中心连线构成轧制力和力的传递,辊系的弹性变形占总变形的90%以上,其精度刚度大大超过现有各类轧机,可轧制目前难以轧制的超宽薄硬韧如钛类金属,对不锈钢、硅钢、马口铁以及汽车钢板等轧制可大大提高宽度、精度和产量。
The utility model relates to a high strength and precision stiff 38 roll system cold rolling mill, which is shown as the attached figure that the 38 rolls which are divided into each 19 rolls as a group on the upper side and the lower side are arranged on a rigid bracket box, the appearance of which is like the normal large-sized mill; the proportion of the length of the working roll and the diameter is 65 to 80, and the proportion of the diameter of the back lining bearing and the working roll is 15. the central connecting line of the contacted rolls can form the transmission of the rolling force and the force; the elastic deformation of the roll system is over 90% of the total deformation; the precision and the rigidity are greatly higher than all kinds of the existing mills; the high strength and precision stiff 38 roll system cold rolling mill can roll the metal which is difficult to be rolled at present and is provided with super width and thinness, and the toughness is like the titanium type. The high strength and precision stiff 38 roll system cold rolling can be used for rolling the stainless steel, the silicon steel, the tinplate, the vehicle plate materials, etc., and the width, the precision, and the yield can be greatly improved.
