1.前言陶瓷、耐火材料在我们这个行业占有很重要的位置,但特种耐火材料,其作用还远未达到应有的程度,至少在一部分工序还有待于开发。碳化硅(SiC)是较常见的特种耐火材料。该材料比其它特种耐火材料价格便宜,与普通耐火材料相比有许多特点:导热性好、耐磨、耐高温、硬度高和不被熔融 1. Preface Ceramics, refractory materials occupy a very important position in our industry, but the special refractory material, its role is far from to the extent possible, at least part of the process remains to be developed. Silicon carbide (SiC) is the more common specialty refractory material. The material is cheaper than other specialty refractory materials and has many characteristics compared to ordinary refractory materials: good thermal conductivity, wear resistance, high temperature resistance, high hardness and no melting
