Cement-free combined gunning mix for carbon-free steel ladle and preparation method of gunning mix
The invention discloses a cement-free combined gunning mix for a carbon-free steel ladle and a preparation method of the cement-free combined gunning mix. The cement-free combined gunning mix comprises the following raw materials: magnesia, corundum, spinel, alpha-Al2O3 micro powder, a binding agent, an anti-explosion agent and a plasticizer. The beneficial effects comprise that the magnesium powder is arranged, the tackifying property is improved, and the magnesium powder has the advantages of good adhesion, good high-temperature performance and no introduction of carbon impurities and calcium oxide impurities. According to the non-cement combined gunning mix for the carbon-free steel ladle, gunning repair can be directly carried out on the part, which is too fast in local melting loss and insufficient in residual thickness, of the steel ladle during cold repair, and the service life of the carbon-free steel ladle is effectively prolonged; integral gunning and lining making can be performed on the steel ladle, and the implementation mode of re-building of carbon-free precast blocks or pouring treatment during overhaul is changed; and in the using process, the non-cement-bonded gunning mix shows excellent molten steel corrosion resistance and scouring resistance, the refractory consumption of steel per ton can be remarkably reduced, the labor intensity of workers is reduced, and the economic benefits and market competitiveness of enterprises are improved.
本发明公开了一种无碳钢包用无水泥结合喷补料及其制备方法，其原料组成包括镁砂、刚玉、尖晶石、α‑Al2O3微粉、结合剂、防爆剂和塑性剂混合组成。本发明有益效果：本发明设置有镁粉，提高增粘的性，具有粘附性好、高温性能好，不会引入碳杂质和氧化钙杂质的优点；本发明无碳钢包用无水泥结合喷补料，可以在冷修时对钢包局部熔损过快、残厚不足的部位直接进行喷补修复，有效延长无碳钢包的使用寿命；并可以对钢包进行整体喷补造衬，改变大修时重新砌筑无碳预制块或套浇处理的实施模式；在使用过程中，无水泥结合喷补料表现出优异的抗钢水侵蚀性能和抗冲刷性能，可以显著降低吨钢的耐材消耗，降低工人的劳动强度，提高企业的经济效益和市场竞争力。
