冶金工业炉内衬的喷补技术是延长炉寿命,降低耐火材料消耗和减轻工人劳动强度的重要技术措施。目前已广泛应用于国内外黑色冶金工业中。据资料介绍,国外有些炼铜厂也有采用喷补来延长炉寿的报导。国内有的冶炼厂在这方面也曾进行过大量的工作。 所谓“喷补”,实际上就是将散状的耐 Metallurgical furnace lining spray technology is extended furnace life, reduce refractory consumption and reduce labor intensity of the important technical measures. Has been widely used in domestic and international black metallurgical industry. According to the information, some foreign copper smelters also use spray to extend the furnace life report. Some smelters in the country have also done a lot of work in this area. The so-called “gunning”, in fact, is the bulk of the resistance
