从一九七八年三月以来,在Von Roll股份有限公司的Gerlafingen钢厂就采用钙喷吹冶金工艺(CAB法)制造优质的自由锻锻件。该厂指出,经CAB法处理的钢制成的锻件具有典型特征。低于0.003％的硫含量总是可以保证重现而且价格相宜。锻件重量30吨以下的钢锭没有硫的偏析。低硫将使横向缺口冲击韧性值改善达一倍之多。经CAB法熔炼的钢的各向同性可跟电渣重熔钢相比。经过钢厂的精心操作和保持必要的边界条件,总是可以达到能重现的高的氧化物纯洁程度。最大夹杂物的尺寸符合钢——铁检验说明书1570/71的4级以上。存在的其它夹杂物多数成为球形(OG型)。即使在大锻件中K_0值也可以达到≤10,而K_4值亦可为0。
Since March 1978, Vla Roll GmbH’s Gerlafingen Steel Works has been manufacturing high-quality free-forging forgings using the calcium injection metallurgical process (CAB method). The plant states that forgings made of CAB-treated steel have typical characteristics. Sulfur content below 0.003% is always guaranteed to be reproducible and affordable. Forgings weighing less than 30 tons of steel ingot sulfur segregation. Sulfur will make the lateral notch impact toughness value improved by up to double. The CAB method of steel isotropic with ESR steel compared. After careful operation of the steelworks and the maintenance of the necessary boundary conditions, high oxide reproducibility can always be achieved. The size of the largest inclusions in line with steel - iron test manual 1570/71 Level 4 or more. Most of the other inclusions present are spherical (OG type). Even in large forgings K_0 value can reach ≤ 10, K_4 value can be 0.
