Abstract

The invention belongs to the technical field of spray coating, and particularly relates to thermal-state repair spray coating for quickly repairing a working lining in a thermal state and a preparation method of the thermal-state repair spray coating. The thermal-state repair spray coating is prepared from the following components in percentage by weight: 70-76% of brown aluminium oxide, 4.5-5.5%of Guangxi white mud, 4.5-5.5% of pure calcium aluminate 70 cement, 1.5-2.5% of boric acid, 4.5-5.5% of silicon metal, 1.5-2.5% of aluminum metal and 7-9% of silicon carbide. According to the thermal-state repair spray coating, in the thermal state, the conditions of severe local erosion, peeling or local damage occurring in the use process of the working lining are quickly repaired, a prepared finished product is good in bonding, high in strength and long in service life.

Description

technical field [0001] The invention belongs to the technical field of spray coatings, and in particular relates to a thermal repair spray coating capable of quickly repairing partial damage of a working lining in a thermal state and a preparation method thereof. Background technique [0002] The lining of continuous casting tundish is generally composed of permanent lining and working lining. The permanent lining is generally made of castable as a whole, and the working lining is generally constructed of magnesium spread material or dry material. During the use of the working lining, there will be serious local erosion, peeling or local damage, which will affect the normal use, and the furnace needs to be shut down for maintenance or dismantling, resulting in large losses and waste. In the prior art, it needs to be cooled to normal temperature before repairing , lacking a kind of spray coating that repairs rapidly under the thermal state and the preparation method of this s...
