一、基本情况这是一项开始于1985年的斯堪的纳维亚合作科研项目,其目的是通过炉子拆炉期间取样和研究,找出炉子生产期内炉衬材料发生了什么变化而最终造成炉衬的损坏。此项目是在3台24—40MW的挪威硅铁电炉于3星期内炉底烧穿之后开始进行的。这是典型的底衬烧穿事故,烧穿总是发生在炉况良好的生产期内,烧穿处正好是在一支电极下面。炉子操作最佳化方面的近期研究以及对工艺过程的认识,通常导致以较低的
First, the basic situation This is a Scandinavian cooperative research project started in 1985, the purpose is through the furnace during sampling and research, to find out the furnace during the production of the lining material what happened and eventually caused Lining damage. The project started after three 24-40 MW Norwegian ferrosilicon furnaces had burned through the hearth in three weeks. This is a typical case of burn-in of a base coat, where burn-through always occurs during a good production phase of the furnace and the burn-through is exactly beneath an electrode. Recent research on furnace operation optimization as well as knowledge of the process often results in lower
