一、前言由于连轧薄板技术的发展,不但要求钢锭坚壳带不要太厚,以避免在轧制时引起钢板边部浪形,而且要求整张钢板性能一致,即要求减少钢锭中心部位的偏析度。采用瓶口模加压盖封顶(机械封顶)生产的沸腾钢锭,基本上可满足以上两点要求。下面简介一炼钢厂进行的瓶口模的初步试验。二、试验条件 1.钢锭模本次试验采用的瓶口模,是在1982年设计的11.44吨瓶口模的基础上按镀锡板宽度要求重新设计的,其主要尺寸见表1。 2.压盖
I. Introduction Because of the development of continuous rolling thin plate technology, not only requires not too thick steel ingot shell, in order to avoid the edge of the plate caused by rolling steel waves, and require the same performance of the entire plate, which requires the reduction of segregation of the central part of the ingot degree. The use of bottle cap pressure cap closure (mechanical cap) production of ingot ingot, basically to meet the above two requirements. The following is a brief introduction of the first trial of a bottle mill in a steel mill. Second, the test conditions 1 ingot die This test used in the bottle die, designed in 1982 on the basis of 11.44 tons of bottle mold tin plate width required redesign, the main dimensions in Table 1.
