目前,国内轧钢连续式加热炉大多采用水冷滑轨。水冷滑轨要有一套水冷系统和辅助设备,冷却水带走大量热能,增加燃料消耗;并造成钢坯加热不均匀,影响轧材质量。太湖耐火材料厂在学习外地试制经验后,于七六年一季度试制成功棕刚玉碳化硅滑轨砖一批,交无锡钢铁厂试用。棕刚玉碳化硅滑轨砖,是将电熔棕刚玉和碳化硅粉碎后作为基本原料,以磷酸铝作结合剂,用1400℃至1450℃高温烧成的无水冷滑轨砖,具有强度高,高温耐磨性好,抗氧化铁渣
At present, most domestic continuous rolling furnaces are water-cooled slides. Water-cooled slide rail to have a water-cooled systems and auxiliary equipment, cooling water take away a lot of heat, increasing fuel consumption; and cause uneven heating billet, affecting the quality of rolled material. Taihu Refractory Plant trial in the field of learning experience, trial production in the first quarter of July, a series of brown corundum silicon carbide slide rail, Wuxi steel plant trial. Brown corundum silicon carbide slide rail tile, is fused fused corundum and silicon carbide crushed as a basic raw material, aluminum phosphate as a binding agent, with 1400 ℃ to 1450 ℃ high temperature firing of cold slide rail tile with high strength, High temperature wear resistance, anti-iron oxide slag
