摘　　要：为了提高再生耐火材料的利用率,制订了出铁沟用再生浇注料和捣打料的行业标准。对出铁沟用再生浇注料和捣打料的组成与性能数据进行了收集和分析,对相关产品的技术条件进行了讨论,对出铁沟用再生浇注料和捣打料行业标准的内容及制订要求进行了介绍。出铁沟用再生浇注料和捣打料应通过成分要求来控制材质;通过对强度、加热永久线变化等重要物理指标的控制来保证炉衬品质。建立适宜的出铁沟用再生浇注料和捣打料行业标准有利于提高再生耐火材料的利用率,降低环境污染。In order to increase the utilization rate of recycled refractory,the industry standard of the recycled castable and ramming refractory used in blast furnace trough has been established.The composition and performance data of the recycled castable and ramming refractory are collected and analyzed,the technical conditions of related products are discussed,and the content and formulation requirements of the industry standard are introduced.It is concluded that the performances of recycled castable and ramming refractory should be controlled through composition requirements and the lining quality should be ensured by controlling the physical index such as strength and permanent change in dimension on heating etc.The establishment of appropriate industry standards for recycled castable and ramming refractory used in blast furnace trough is conducive to improving the utilization rate of recycled refractory materials and reducing environmental pollution.
