前言过去几年,各种类型的铬合金消耗数量变化很大。首先,不锈钢生产技术的变化对铬合金的品种和消耗影响很大。过去大量使用低炭铬铁,而现在高炭铬铁的利用日趋增加,这是由于不锈钢冶炼技术发生了变化才有可能。目前传统的电弧炉正在被氧气吹炼、真空脱炭和氩氧精炼所代替。把高炭铬铁用于上述冶炼工艺,虽然从原料观点来看不一定是最理想的条件,但是 Preface Over the past few years, the amount of various types of chrome alloys varies widely. First of all, changes in stainless steel production technology have a great impact on the variety and consumption of chromium alloy. In the past, extensive use of low-carbon ferrochrome, and now the use of high-carbon ferrochromium increasing, which is due to changes in stainless steel smelting technology is possible. The traditional electric arc furnace is being oxygen blowing, vacuum carbon off and argon oxygen refining instead. The use of high-carbon ferrochromium for the above smelting process, although not necessarily the best from raw material point of view, but
