摘    要:分析了304不锈钢电炉冶炼流程的传搁时间和传搁过程温降情况,建立各个工序冶炼温度制度与连浇炉数的关系,得知已有温度制度下的连浇炉数仅为2炉,并以6炉连浇为例给出不同连浇炉数情况下温度制度.通过计算流程中传搁能耗,讨论了连浇炉数与浇次总传搁能耗和平均传搁能耗的关系.提出了一种考虑传搁能耗确定最优连浇炉数的方法.对比发现,当增加连浇炉数的传搁能耗小于开浇一次耗材消耗的能耗时,最大连浇炉数为最为合理的连浇炉数.

Abstract:Both transport time and temperature drop in transport processes were analyzed for the 304 stainless steel smelting flow in an electric arc furnace (EAF). The relationship between the temperature schedule in each process and continuous casting heats was established. In the existing temperature schedule the number of continuous casting heats was two. The temperature schedule with different continuous casting heats was presented by taking the process of six continuous casting heats for example. The transport energy during transport processes was calculated so as to analyze the relationship between continuous casting heats and different types of transport energy. A method for determining the optimum number of continuous casting heats was proposed which takes the transport energy into account. When the transport energy of increasing the continuous casting heats is less than the consumables' energy consumption of a new casting, the most number of continuous casting heats is the optimum.
