Heat insulation coating material for permanent layer of torpedo ladle
The invention discloses a heat insulation coating material for a permanent layer of a torpedo ladle, and mainly solves the technical problems of high heat conductivity coefficient, large temperature drop of molten iron in a molten iron transportation process and poor adhesion performance with the steel shell of the torpedo ladle in the existing torpedo ladle. The heat insulation coating material for the permanent layer of the torpedo ladle comprises the following raw material components in percentage by weight: 35-44% of lightweight alumina, 25-35% of hollow micro-particles, 16-25% of silicon micro-powder, 6-10% of mullite micro powder, 3-5% of magnesia and 2-8% of nano aluminum powder, wherein the sum of the weight percentages of the raw material components is 100%, the hollow micro-particles are sodium aluminosilicate hollow microspheres, and the volume density of the lightweight alumina is 1.7 to 1.9 g/cm<3>. According to the invention, the heat conductivity coefficient of a torpedo ladle permanent layer prepared from the coating material is 0.022-0.035 W/(m.K) at a temperature of 600 DEG C.
本发明公开了一种鱼雷罐永久层用隔热涂抹料，主要解决现有鱼雷罐的导热系数高、运输铁水过程铁水温降大、与鱼雷罐罐钢壳体附着性能差的技术问题。本发明提供的鱼雷罐永久层用隔热涂抹料，其原料组分的重量百分比为：轻量化矾土35～44％，中空微粒25～35％，硅微粉16～25％，莫来石微粉6‑10％，菱苦土3‑5％，纳米铝粉2～8％，所述原料组分的重量百分比之和为100％；所述中空微粒为硅铝酸钠空心微珠；所述轻量化矾土的体积密度为1.7‑1.9g/cm3。本发明涂抹料制成的鱼雷罐永久层在600℃导热系数为0.022‑0.035W/(m·K)。
