Continuous casting nozzle inner wall coating
The invention belongs to the technical field of continuous-casting functional refractory materials, and provides a continuous casting nozzle inner wall coating. The continuous casting nozzle inner wall coating is prepared from, by mass, 20%-40% of Bonite of which the particle size is larger than 0 mm and smaller than or equal to 1 mm, 40%-60% of a light porous material of which the particle size is larger than 0 mm and smaller than or equal to 1 mm, 5%-20% of alpha-Al2O3 of which the particle size is 325 meshes, 5%-20% of silica of which the particle size is 80 meshes, 5%-15% of a binding agent, 1%-5% of a thickening agent of which the particle size is 325 meshes and water, wherein the adding amount of the water accounts for 50%-100% of the total weight of the raw materials. A lining prepared from the coating has the lower size density and the reasonable pore structure, therefore, the heat conductivity of the lining is lower, the heat-insulating property is more excellent, the problem of matrix damage caused by mismatch of the thermal and mechanical properties does not exist, and the better social benefit and economic benefit are achieved.
