老轧机的缺点及其改造方法诺因基尔兴厂于1963年投产了一台连续式三线线材轧机,用来轧制直径为50～25mm的线材和棒材,方钢、六角钢和扁钢。扭转布置的2辊式25机架轧机(其中17个机架作为粗轧机和中间轧机,另8架为精轧机组),以及艾登博恩式、加雷特式卷取机和齿条冷床(如图1所示)均不再适应于当前技术发展水平和用户要求。原来采用的原料为85方坯,不能选用价格合理的连铸坯。因此,在改造方案中考虑采用125方钢。对于许多轧钢厂来说,最大卷重只有66D
The shortcomings of the old rolling mill and its reconstruction method Inkyill plant in 1963 put into operation a three-wire wire rod mill for the rolling diameter of 50 ~ 25mm wire rod and bar, square steel, hexagonal and flat steel . Twisted, two-roller 25-stand mills (17 of which are roughing and intermediate mills and the other 8 are finishing mills), as well as the Aydin-Born, Gallett coiler and rack cold Bed (shown in Figure 1) are no longer adapted to the current state of the art and user requirements. The original raw materials used for the 85 billet, can not choose a reasonable price of slab. Therefore, in the transformation program to consider the 125 square steel. For many rolling mills, the maximum roll weight is only 66D
