目前,国外在连铸连轧线上采用的铸坯轧机有森吉米尔行星轧机、Krupp/Platzer行星轧机和摆式锻轧机等。虽然摆式锻轧机是近几年才出现的新设备,但它显示出了较大的技术经济意义。其优点如下:1.水平轧辊(或锻轧头)和垂直轧辊(或锻轧头)设有孔型,其压下量可以不同,因而能生产方坯、扁坯、矩形坯、椭圆坯、近似的圆坯;2.可代替一般初轧机或坯料轧机,操作维护简单容易,换辊迅速,约20分钟;3.综合了锻压和轧制的工艺特点,锻轧出来的坯料的金相组织比较致密,从而提高了
At present, there are Sendzimir Planetary Rolling Mill, Krupp / Platzer Planetary Rolling Mill and Tilting Forging Rolling Mill adopted in foreign continuous casting and rolling line. Although the pendulum type forging mill is a new device that has appeared in recent years, it shows great technical and economic significance. The advantages are as follows: 1. The horizontal rolls (or forging heads) and the vertical rolls (or forging heads) are provided with a hole pattern of which the reduction amount can be different so that billets, slabs, rectangular billets, oval billets, Approximate round billet; 2. can replace the general initial mill or billet mill, easy operation and maintenance, rapid roll change, about 20 minutes; 3. Forging and rolling process characteristics, forging out of the blank microstructure More dense, thereby improving
