BMC converter bottom thermal-state repairing material and repairing method
The invention discloses a BMC converter bottom hot-state repairing material and a repairing method. The BMC converter bottom hot-state repairing material comprises the following components in percentage by weight: 36-54% of magnesium-calcium-iron sand, 25-35% of magnesia powder, 3-9% of magnesia micro powder and 16-20% of nano silica sol. After being repaired by the material, the converter has higher strength, can resist erosion and oxidation, prolongs the service life of the converter after one-time repairing, and is short in repairing process time, green and environment-friendly, and low in repairing material cost; in addition, the converter bottom and blowing elements are good in air permeability and not blocked, bottom blowing smoothness of the whole furnace service is achieved, and the service life of the bottom blowing air supply elements is synchronous with the furnace life.
一种BMC转炉炉底热态修补材料及修补方法，其成分重量百分比为：镁钙铁砂36～54％，镁砂粉25～35％，镁砂微粉3～9％，纳米硅溶胶16～20％。用本发明所述材料修补后保证转炉具有较高的强度，可以抗侵蚀、抗氧化，提高了单次补炉后转炉使用寿命，修补过程时间短、绿色环保、修补材料成本低；并且，保证转炉炉底及喷吹元件透气性好不堵塞，实现全炉役底吹畅通、底吹供气元件寿命与炉龄同步。
