Method for quickly repairing high-temperature kiln

Abstract

The invention discloses a method for quickly repairing a high-temperature kiln. The method comprises the following steps that S1, partially-damaged castable materials are dismantled, an anchoring partis dismantle, and residuals of the anchoring part is polished to be flat; S2, after the damaged castable materials are dismantled, masonry of clay bricks is carried out along a wall of a cylinder, and a new anchoring part is used for fixing during masonry; S3, after the masonry of the clay bricks is completed, the masonry of working layer bricks is carried out on the surfaces of the clay bricks and the surfaces of the original castable materials, and a new anchoring part is used for fixing during masonry; S4, after the masonry of the working layer bricks is completed, the working layer bricksare used as molds, masonry seams outside the cylinder are filled with the castable materials; and S5, after the seams are filled with the castable materials, a hot blast stove is heated and baked after eight hours. According to the method, the maintenance period is short, the time is about 5 days, the maintenance time can be saved, and the blowing out cost is reduced.

Description

technical field [0001] The invention relates to the field of kilns, in particular to a method for quickly repairing high-temperature kilns. Background technique [0002] At present, the horizontal hot blast stoves used by most domestic chemical processing enterprises are all natural gas hot blast stoves, and the high-temperature gas after the burner is used to be directly discharged to the heating workshop through the air duct by the fan. Most of the natural gas hot blast stoves are fired with natural gas in the hot blast stove. After the natural gas burns, most of the flames will directly burn the refractory material on the top of the hot blast stove, which will easily cause damage to the refractory material poured on the top of the hot blast stove. It is soft and easy to fall off. Now the method of overall dismantling is generally used, and the overall removal of the original castable, and then the overall pouring makes the entire maintenance cycle longer, the time is abou...

Problems solved by technology

Most of the natural gas hot blast stoves are fired with natural gas in the hot blast stove. After the natural gas is burned, most of the flames will directly burn the refractory material on the top of the hot blast stove, which will easily cause damage to the refractory material poured on the top of the hot blast stove. It is soft and easy to fall off. Now the method of overall dismantling is generally used, and the overall removal of the original castable, and then the overall pouring makes the entire maintenance cycle longer, the time is about 10 days, and the maintenance cycle is longer, which affects the use of the hot stove and the company.
