Problems solved by technology

[0004] However, in the actual use process, the inventors found that the existing anti-oxidation enamel layer is only a simple physical connection with the above-mentioned working surface of the continuous casting. Generally, the coating treatment is carried out after the continuous casting is fired. The treatment can only coat the coating layer on the working surface. The service life of the coating layer is not long during continuous casting, and it is easy to cause local rapid consumption due to uneven coating in some areas, which further makes the anti-oxidation enamel The overall failure of the layer makes the service life of the continuous casting unstable and generally short
In addition, the inventor also found that the existing anti-oxidation enamel la

Abstract

The invention discloses a coating glaze, which comprises main materials and auxiliary materials, wherein the main materials comprise, by weight, 15-25% of quartz, 3-10% of boron carbide, 40-60% of boron glass, 3-10% of toner, 5-15% of glaze dissolving powder, and 5-15% of white corundum, and the auxiliary materials comprise a binder accounting for 20-35% of the total weight of the main materials,water glass accounting for 30-50% of the total weight of the main materials, a dispersant accounting for 0.5-1% of the total weight of the main materials, and a suspending agent accounting for 0.2-0.5% of the total weight of the main materials. The invention further discloses a use method of the coating glaze, wherein the use method comprises: 1, mixing the main materials and the auxiliary materials, and carrying out ball milling for 2-3 h to prepare a uniformly-mixed coating glaze composition; and 2, carrying out spray coating at a working area, and carrying out high temperature heating. According to the present invention, quartz, boron carbide, boron glass and white corundum are used as the main materials, have different melting temperatures, and can well react with each other during thehigh temperature firing to generate the dissolving phase, wherein the continuous casting member and the coating glaze can be closely combined through the dissolving phase so as to solve the technicalproblem of the unstable use performance of the physical coating.

Description

technical field [0001] The invention relates to the field of inorganic non-metallic materials, in particular to a glaze and a method for using the glaze. Background technique [0002] Refractories are important basic materials in basic industries such as iron and steel, non-ferrous metals, building materials, and petrochemicals, and are indispensable and important supporting materials for high-temperature industrial thermal equipment. The "three major parts" of continuous casting include the ladle shroud, the tundish stopper and the tundish submerged nozzle. Among them, the working section of the ladle shroud is provided with an anti-oxidation layer to prevent the carbon material from being oxidized; and the lining material It needs to have excellent thermal shock resistance; the tundish stopper rod is mainly used for the opening and closing of the tundish. In addition to automatically controlling the flow of molten steel from the tundish to the crystallizer, it can also flo...
