Spray coating for blast furnace cast iron cooling wall and blast furnace lining joint and preparation method thereof
The invention discloses a spray coating for a joint of a blast furnace cast iron cooling wall and a blast furnace lining and a preparation method of the spray coating, and solves the technical problemthat a gap is generated between an existing blast furnace lining refractory material and the blast furnace cast iron cooling wall. The invention relates to a spray coating for a joint of a blast furnace cast iron cooling wall and a blast furnace lining. The composition is prepared from the following components: the content of SiC is 70-82%, the content of Al2O3 is 4-9.5%, the content of Ni is 1-9.5%, the content of Cr is 0.55-1.60%, the content of Fe is 0.45-1.30%, the content of CeO2 is 0.5-1.0%, the content of SiO2 is 3.0-5.0%, the content of spherical asphalt is 0.5-2.0%, and the balance is water and other inevitable impurities, all the components adding to 100 wt% in total. The thermal conductivity coefficient of the spray coating is 14-16 W/m*K, and the spray coating can be independently a blast furnace lining refractory material and can also be a transition layer between a blast furnace lining and a cast iron cooling wall.
本发明公开了高炉铸铁冷却壁与高炉炉衬结合部用喷涂料及其制备方法，解决现有高炉炉衬耐材与高炉铸铁冷却壁之间产生缝隙的技术问题。本发明一种高炉铸铁冷却壁与高炉炉衬结合部用喷涂料，其组成组分的重量百分比为：SiC 70～82％,Al2O34～9.5％,NiO 1～9.5％,Cr 0.55～1.60％,Fe 0.45～1.30％,CeO20.5～1.0％,SiO23.0～5.0％,球状沥青0.5～2.0％，其余为水及其他不可避免的杂质，各组成组分的重量百分比之和为100％。本发明喷涂料的导热系数为14～16W/m·K，喷涂料既可单独为高炉炉衬耐材，又可为高炉炉衬与铸铁冷却壁之间的过渡层。
