Repairing material for tapping hole of converter and preparation method of repairing material
The invention relates to a converter tapping hole repairing material and a preparation method thereof, the converter tapping hole repairing material comprises a repairing layer and an enamel layer, the repairing layer comprises the following raw materials: pretreated high-purity magnesia, carboxymethyl cellulose and a binding agent; pretreatment of high-purity magnesia: soaking the high-purity magnesia in an aqueous solution of magnesium sulfate heptahydrate for more than 24 hours, taking out the high-purity magnesia, and drying the high-purity magnesia at the temperature of 100-110 DEG C; the glaze layer is prepared from the following raw materials: glass powder, potassium feldspar powder, quartz powder, SiC fine powder, chromium oxide green and water. The converter tapping hole repairing material has the advantages that the converter tapping hole repairing material uses the high-purity magnesia soaked in the magnesium sulfate heptahydrate aqueous solution as the main raw material according to the use position and the requirement characteristics of a steel mill, so that the disintegration property of the material is improved, and the tapping hole replacement time is shortened. The repairing layer is excellent in disintegration, and the volume stability of the repairing agent is effectively improved at high temperature due to the added carboxymethyl cellulose or clay and the binding agent.
本发明涉及一种转炉出钢口修补料及制备方法，包括修补层、釉层，所述的修补层由以下原料组成：经预处理的高纯镁砂、羧甲基纤维素、结合剂；高纯镁砂的预处理：将高纯镁砂浸泡在七水硫酸镁的水溶液中24小时以上，取出在100～110℃温度下烘干；釉层由以下原料组成：玻璃粉、钾长石粉、石英粉、SiC细粉、氧化铬绿、水。优点是：转炉出钢口修补料根据使用位置及钢厂的需要特性，使用浸过七水硫酸镁水溶液的高纯镁砂为主要原料，提高了物料的解体性，缩短了更换出钢口时间。修补层解体性优良，添加的羧甲基纤维素或粘土及结合剂，在高温时有效地改善了修补剂的体积稳定性。
