绝热板广泛用于镇静钢钢锭模帽部保温,可提高钢锭成坯率。由鞍山钢铁学院、太原钢铁公司、鞍山陶瓷七厂共同研制的“PS”新型绝热板更为突出。它是以电厂粉煤灰空心微珠作骨料,配加适量复合结合剂,采用半干机压成型,尺寸精确,板面平整。经钢厂生产使用表明:该绝热板抗钢水侵蚀能力强;高温条件下保温性能好、使其钢锭头部呈平盘状收缩,在相同条件下,用“PS”板的缩 Insulation panels are widely used in the insulation of steel ingot mold cap insulation, can improve the ingot into billet rate. From “Anshan Iron and Steel Institute, Taiyuan Iron and Steel Company, Anshan ceramics plant jointly developed seven” PS “new insulation panels are more prominent. It is based on fly ash hollow beads for the aggregate, with an appropriate amount of composite binder, the use of semi-dry machine pressure forming, precise size, plate surface formation. The use of steel production shows that: the insulation resistance to molten steel erosion; good performance under high temperature insulation, the head of the ingot showed flat disc contraction, under the same conditions, with ”PS" shrink
