Micro-powder combined smearing repair material for steel ladle lining and preparation method and application thereof
A micro-powder combined smearing repair material is prepared from a raw material A and a raw material B in parts by weight, wherein the raw material A comprises 20-35 parts of recycled corundum aggregate, 45-60 parts of tabular corundum, 6-7 parts of magnesia, 2-6 parts of a micro-powder binding agent and 8-11 parts of other micro-powder; the raw material B is prepared from the following components; the explosion-proof fibers account for 0.1% of the total weight of the raw material A. The micro-powder combined smearing repair material provided by the invention has relatively good cohesiveness,easy construction and high intensity, the sintering of the material is promoted at high temperature, the steel ladle lining material can be firmly permeated and bonded with the surface of the steel ladle lining material, the slag resistance is good, the scour and corrosion resistance of molten steel and steel slag is good, the effect of protecting a working lining is achieved, the use effect is good, and meanwhile, the aggregate part of the steel ladle lining material is used as a used corundum recycled material to realize the recycling of resources.
本发明涉及其由如下重量份A原料和B原料制成：A原料包括：回收刚玉骨料20～35份、板状刚玉45～60份、镁砂6～7份、微粉结合剂2～6份、其它微粉8～11份；B原料包括：相当于所述A原料总重量0.1％的防爆纤维，本发明所提供的微粉结合涂抹修补料具备较好的粘结性，易于施工，强度高，高温促进材料烧结，能较好的与钢包内衬材料表面形成牢固的渗透粘结，抗渣性能好，抵抗钢水及钢渣的冲刷和侵蚀的性能，起到保护工作衬的作用，具有较好的使用效果,同时该产品骨料部分使用用后刚玉回收料，以实现资源的回收利用。
