轧钢加热炉对耐火材料的要求是高温结构性能要好,(指造型性、整体性、气密性和保温性等),绝热效果明显、造价低廉便于施工。 由于传统的砖砌炉衬的高温性能和结构性能比较差,能耗也较高。因此,正逐步被复合材质和不烧制品——不定型的耐火材料炉衬所代替。早在五十年代末,我国有不少加热炉开始采用水泥结合耐火混凝土浇注炉衬来代替砖砌炉衬并取得了一定效果。但是,这种耐火材料的性能仍不够理想。到七十年代就已应用了高温性能和结构性能较好而又省能的耐火可塑 Steel rolling furnace refractory requirements of high temperature structural properties better, (refers to the modeling, integrity, airtightness and insulation, etc.), thermal insulation effect is obvious, low cost and easy construction. As the traditional brick lining high temperature performance and structural performance is relatively poor, high energy consumption. Therefore, it is gradually being replaced by composite materials and unfired refractory linings. As early as the late fifties, many furnaces in China began to use cement combined with refractory concrete pouring lining instead of brick lining and achieved some results. However, the performance of this refractory is still not satisfactory. By the seventies have been applied to the high temperature performance and structural performance is better and energy-saving fire-resistant plastic
