Carbon-free steel ladle wall repairing material produced by adding waste reinforcing material and preparation method of carbon-free steel ladle wall repairing material
The invention relates to a carbon-free steel ladle wall repairing material produced by adding waste reinforcing materials and a preparation method thereof. The repairing material is prepared from the following raw materials in parts by weight: 10-30 parts of 6-3mm sintered corundum granules, 10-30 parts of 3-1mm sintered corundum granules, 10-30 parts of fused white corundum granules less than or equal to 1mm, 1-10 parts of 97 fused magnesia granules less than or equal to 1mm, 10-20 parts of 240-mesh fused white corundum powder, 1-10 parts of 240-mesh 97 fused magnesia powder, 3-10 parts of aluminate cement, 3-10 parts of calcined alumina micro powder, 1-5 parts of silicon dioxide superfine powder and 1-5 parts of Guangxi white mud. 0.1-0.5 part of polypropylene fiber, 2-8 parts of waste ceramic powder and 2-8 parts of vanadium-titanium slag powder. According to the invention, solid wastes, namely the waste ceramic powder material and the vanadium-titanium slag material, are introduced into the steel ladle wall repairing material, and a ceramic phase and a high-temperature liquid phase are formed at medium and high temperatures to reinforce and toughen, so that the medium and high-temperature strength of the repairing material is remarkably improved, and the matrix bonding performance of the repairing material is improved.
本发明涉及一种添加固废材料生产的无碳钢包包壁修补料及制备方法，所述修补料是由下列重量份数的原料制备而成：6～3mm烧结刚玉颗粒料10～30份、3～1mm烧结刚玉颗粒料10～30份、≤1mm电熔白刚玉颗粒料10～30份、≤1mm的97电熔镁砂颗粒料1～10份、电熔白刚玉粉240目10～20份、97电熔镁砂粉240目1～10份、铝酸盐水泥3～10份、煅烧氧化铝微粉3～10份、二氧化硅超微粉1～5份、广西白泥1～5份、聚丙烯纤维0.1～0.5份、废弃陶瓷粉2～8份、钒钛矿渣粉2～8份。本发明在钢包包壁修补料中，引入固体废弃物—废弃陶瓷粉材料、钒钛矿渣材料，通过中高温形成陶瓷相与高温液相，补强增韧，显著改善修补料的中高温强度，改善其基质粘结性能。
