Research Development on Performance of Industrial Insulation Coating

摘要

Ability to testify effect of carboxymethocel cellulose, use 5000-mesh hollowness particle, carboxymethocel cellulose and sodium silicate to study anti-fatigue nature of coating, examine performance of industrial test, apply metallurgy transmission method to build math model and check test results by comparison of theory value and test value. Carboxymethocel cellulose enhances adhesion performance between coating and steel plate, resolves key matter that coating tends to come off in test. Continuous heating-cooling tests displayed that insulation performance of coating doesn't reduce with reduplicative application, anti-fatigue test has no effect on insulation performance. Insulation coating can play a role in industrial production. After coating was applied in steel ladle, temperature drop of liquid steel notably decreased, energy consumption reduced accordingly in steelmaking, steel plant can obtain direct economic benefit. Thickness of coating is 0.8mm, test value approximates theory value for outer temperature of steel plate.
