电炉,配以炉外精炼炉,使电炉成为熔化钢水的手段。精炼炉完成电炉还原期各项任务,再加上真空脱气,钢包吹氩;后步工序再配以直读光谱分析合金元素,以代替常规的湿法与比色法的化学分析,使冶炼含20～30种合金元素的高温、耐热合金钢如履平地,简易可行。这个方法是六十年代初期在国外兴起,如今已风瀰世界。我国炉外精炉是七十年代后期从国外引进的,到而今已
Electric furnace, together with the furnace outside the furnace, the electric furnace as a means of melting molten steel. Refining furnace to complete the reduction task of the furnace, coupled with vacuum degassing, ladle argon; step-by-step process coupled with direct reading spectroscopy of alloying elements to replace the conventional wet and colorimetric chemical analysis, so smelting Containing 20 to 30 kinds of alloying elements of high temperature, heat-resistant alloy steel such as leveling, simple and feasible. This method was started in a foreign country in the early 1960s, and now it has been used by the world. China’s furnace outside the fine furnace is imported from abroad in the late seventies, and now has
