Heat-resistant spray coating for slag ladle and preparation method of heat-resistant spray coating
The invention discloses a heat-resistant spray coating for a slag ladle and a preparation method of the heat-resistant spray coating. The heat-resistant spray coating comprises the following raw materials in percentage by mass: 5-10% of high-aluminum wool, 5-10% of silicon carbide, 5-10% of silicon carbide and the balance of water. 25-40% of quartz sand or recycled high-alumina brick powder; 7-12% of Yixing mud or Suzhou soil; 5-10% of a liquid binder; 0.05 to 0.5 percent of a water-retaining agent; 0.01%-0.1% of a foaming agent; and 40-50% of water. The heat-resistant spray coating for the slag ladle disclosed by the invention has the advantages of better properties, good adhesion property, no rebound, high strength, good slag corrosion resistance, easiness in slag turnover, low heat conductivity coefficient and good heat preservation effect, can realize direct treatment of high-temperature liquid slag on a roller, shortens the slag treatment flow, effectively prolongs the tank age, improves the slag treatment efficiency and reduces dust pollution.
本发明公开了一种用于渣罐的阻热喷涂料及其制备方法，所述的阻热喷涂料的原料质量百分组成为：高铝棉5～10％；石英砂或回用高铝砖粉25～40％；宜兴泥或苏州土7～12％；液体结合剂5～10％；保水剂0.05～0.5％；发泡剂0.01～0.1％；水40～50％。本发明公开的渣罐阻热喷涂料的各项性能均较好，附着性能好、不反弹、强度高、抗渣侵蚀性能好、翻渣容易、导热系数低保温效果好，可实现高温液态渣直接上滚筒渣处理，缩短渣处理流程，有效提高罐龄，提高渣处理效率，减少粉尘污染。
