Hot-state repairing material for steel ladle and preparation method of hot-state repairing material
The invention relates to a hot-state repairing material for a steel ladle and a preparation method. The hot-state repairing material comprises the following raw materials in parts by weight: 20-40 parts of 0-5mm fused magnesia; 10-30 parts of alumina micro powder with a particle size of 0-50 [ 20 to 40 parts of white corundum powder with a particle size of 0 to 1 mm 5-10 parts of boric acid; 5 to 12 parts of 200-mesh magnesium powder; and 6-12 parts of solid water glass. The method has the advantages that a carbon source is not added, heat generated by the steel ladle lining can cause an exothermic reaction between magnesium powder and oxygen, and high heat released by the exothermic reaction can partially melt and soften a repairing material in a to-be-repaired area before the repairing material is deposited on a substrate of the steel ladle lining; and meanwhile, the released heat can partially soften and melt the surface of the steel ladle lining to be repaired, the other part of the mixture is used for filling, the solid water glass has good adhesion performance and can react with the repairing material on the upper layer while reacting at high temperature, and the steel ladle lining can be repaired within a short time.
本发明涉及一种钢包用热态修补料及制备方法,按重量份包括以下原料:电熔镁砂0~5mm 20~40份;氧化铝微粉0~50μm 10~30份;白刚玉粉0~1mm 20~40份;硼酸5~10份;镁粉200目5~12份;固体水玻璃6~12份。优点是:不增加碳源,钢包内衬产生的热量会使镁粉和氧气之间发生放热反应,放热反应释放出来的高热量能使待修补区域的修补料沉积在钢包内衬基底之前将其部分熔融软化;同时释放出来的热量也会部分软化和熔融欲修补的钢包内衬表面,再由另一份的混合料填补,固体水玻璃具有很好的粘附性能,并在高温下自身反应的同时能够与上一层的修补料反应,短时间内实现修补钢包内衬。
