三辊开坯机一般按下面的经验公式来选择坯料尺寸: L=0.4×D 式中:L-坯料边长,mm D-轧辊名义直径,mm 据此,适于400轧机的坯料尺寸为115～160mm方坯钢锭,或6″钢锭,最大坯料尺寸为180mm的方坯。但是,能不能用现有的400轧机将28″钢锭轧成58mm的方坯呢?我们进行了探索。 1、试验条件我厂的开坯车间是1970年建成的,车间平面布置如图1所示。用16″钢锭生产50mm的方坯时,道次排列为6-3-1-1,共11道次。如生产58mm的方坯时,则为6-3-0-1,共10道次。第一列为400×2机列,主传动电动机功率为
The three-roll open billet press generally selects the blank size according to the following empirical formula: L = 0.4 × D Where: L-side length of the blank, mm D-D nominal roll diameter mm According to this, the billet size suitable for a 400 mill is 115 ~ 160mm billets, or 6 “ingots, billets with a maximum billet size of 180mm However, is it possible to roll a 28” ingot into 58mm billets using the existing 400 rolling mill? 1, test conditions I plant billet workshop was built in 1970, the workshop layout shown in Figure 1. When a billet of 50 mm is produced using a 16 "ingot, the passes are arranged 6-3-1-1 in total of 11 passes, 6-3-0-1 for 58 mm billet, 10 passes The first column is 400 × 2 machine, the main drive motor power is
