The invention discloses a heat-resisting spray coating for slag tanks and a preparation method thereof. The raw material mass percentage of the heat-resisting spray coating is composed of: 5-10% of high-alumina cotton; quartz sand or recycled high-alumina brick powder 25-40%; Yixing mud or Suzhou soil 7-12%; liquid binder 5-10%; water-retaining agent 0.05-0.5%; foaming agent 0.01-0.1%; water 40-50%. The heat-resistant spray coating for slag pots disclosed by the invention has good properties, good adhesion, no rebound, high strength, good slag erosion resistance, easy slag turning, low thermal conductivity and good heat preservation effect, and can realize high-temperature liquid slag The slag is processed directly on the drum, which shortens the slag treatment process, effectively increases the tank life, improves the slag treatment efficiency, and reduces dust pollution. |
