众所周知,浇铸法是制造用来轧制或锻造成型钢锭的传统方法。就钢材的质量来说,这种工艺方法具有某些缺陷,主要是钢锭的成分和组织会发生变化。虽然熔化状态的钢,其组织十分均匀,但浇铸成钢锭后就不可避免地会产生偏析。这种偏析不仅使钢锭难于轧制和锻造,而且还会影响这种钢制工件的质量、性能和可加工性。 As we all know, casting method is to create the traditional method for rolling or forging forming ingot. In terms of the quality of the steel, this process has certain drawbacks, mainly the composition and organization of the steel ingot. Although the molten state of the steel, the organization is very uniform, but after casting into ingot inevitably produce segregation. This segregation not only makes ingots difficult to roll and forge, but it also affects the quality, performance and workability of such steel workpieces.
