目前,人们对隔热材料和高强耐高温纤维组成复合材料问题很重视。为了加固热工设备衬体,向衬体材料中掺入一定量高温纤维,就能使其强度和线变化得到明显改善。经研究证明,以冶金和磨料工业的废料——铝钙渣、铬铁渣或锰铁渣、电熔刚玉残渣和液体水玻璃为基础,再掺加高岭土纤维或石英纤维制成的耐火材料其持久强度和冲击韧性分 At present, people attach great importance to the issue of composites made of heat-insulating materials and high-temperature-resistant fibers. In order to reinforce the thermal equipment lining, the lining material into a certain amount of high-temperature fiber, can make its strength and line changes significantly improved. The study proved that the metallurgical and abrasive industry waste - aluminum calcium slag, ferrochrome slag or ferromanganese slag, fused corundum residue and liquid water glass based, and then mixed with kaolin fiber or quartz fiber refractory material Long-lasting strength and impact toughness points
