Quick repairing material for repairing tapping hole of converter and construction method thereof
The invention discloses a quick repairing material for repairing a tapping hole of a converter and a construction method thereof, and the quick repairing material comprises the following raw materials in percentage by weight: 25-35% of electric smelting skin sand particles, 60-70% of electric smelting magnesia, 3-7% of silica powder, 0.05-0.1% of a retarder, 0.5-1% of a suspending agent, 0.1-0.5% of a dispersing agent, 0.1-0.5% of a plasticizer and 0.5-1% of a magnesian self-flow water reducing agent. The quick repairing material for repairing the tapping hole of the converter, provided by the invention, is suitable for maintaining pits around the tapping hole, has the advantages of good fluidity, good slag corrosion resistance, high high-temperature strength, short sintering time, good repairing effect, high repairing speed and long service life, has the service life of more than 20 furnaces, saves the smelting time for a steel mill, and improves the production efficiency. The production cost is effectively reduced, and the method is suitable for industrial popularization and application.
本发明公开了一种用于修补转炉出钢口的速补料及其施工方法，其中，速补料以重量百分比计包括以下原料：25～35％的电熔皮砂颗粒、60～70％的电熔镁砂、3～7％的硅微粉、0.05～0.1％的缓凝剂、0.5～1％的悬浮剂、0.1～0.5％的分散剂、0.1～0.5％的增塑剂和0.5～1％的镁质自流减水剂。本发明提供的用于修补转炉出钢口的速补料，适合维护出钢口周围的凹坑，具有流动性好、抗渣侵蚀性能好、高温强度大、烧结时间短、修补效果好、修补速度快和使用寿命长的优点，本发明速补料的使用寿命达20炉以上，为钢厂节约了冶炼时间，有效地降低生产成本，适合工业化推广应用。
