Problems solved by technology

[0002] Various boilers and other kilns are used in the chemical industry and electric power fields. When these kilns fail and need to be repaired, they need to be shut down, and the production will be suspended for a long time. The shutdown of the equipment will cause a large loss to the equipment. , Suspension of production also brings greater economic losses to manufacturers
In order to reduce the loss, people start from various directions. From the repairing materials, castables and plastics are used for repairing. However, the use of these materials is limited, the construction is inconvenient, and it takes a long time to bake the kiln to restore Production, which greatly occupies the production time of the kiln, increases the maintenance cost and reduces the profit of the enterprise

Embodiment example 1

[0015] Taking the production of 1000kg repair material as an example, the raw materials are 400kg of bauxite particles, 200kg of corundum particles, 80kg of corundum fine powder, 50kg of silicon micropowder, 100kg of alumina micropowder, 140kg of aluminum dihydrogen phosphate micropowder, 20kg of calcium aluminate cement, and active metal aluminum powder 10kg, and the raw materials are mixed evenly to obtain the finished no-bake repair material.

Embodiment example 2

[0017] Taking the production of 1000kg repair material as an example, the raw materials are 450kg of bauxite particles, 200kg of corundum particles, 100kg of corundum fine powder, 20kg of silicon micropowder, 50kg of alumina micropowder, 150kg of aluminum dihydrogen phosphate micropowder, 20kg of calcium aluminate cement, and active metal aluminum powder 10kg, and the raw materials are mixed evenly to obtain the finished no-bake repair material.

Embodiment example 3

[0019] Taking the production of 1000kg repair material as an example, the raw materials are 400kg of bauxite particles, 250kg of corundum particles, 60kg of corundum fine powder, 40kg of silicon micropowder, 90kg of alumina micropowder, 130kg of aluminum dihydrogen phosphate micropowder, 20kg of calcium aluminate cement, and active metal aluminum powder 10kg, and the raw materials are mixed evenly to obtain the finished no-bake repair material.

[0020] When the kiln needs to be repaired, the above-mentioned repairing material is sprayed to the designated position, and then the exterior is maintained. The repairing material is repaired at the high temperature of the kiln itself, and the baking process is left.

[0021] To sum up, the repairing material of the present invention has fast repairing speed, firm structure after repairing, and long service life. It can be used without stopping the furnace, and does not need to be baked after repairing. It effectively increases the s...

Abstract

The invention provides a baking-free repairing material, particularly a repairing material used for rapid repairing of various kilns in the chemical industry. Bauxitic rock and corundum are adopted as main raw materials. A binder that is aluminum dihydrogen phosphate, a coagulant that is calcium aluminate cement, an agglutinant that is alumina micropowder and a quick-drying agent that is metal aluminum powder are added and mixed with the main raw materials to obtain the repairing material. The repairing material includes, by weight, 61-75 parts of the bauxitic rock and the corundum, 12-15 parts of the binder, 2 parts of the coagulant, 5-10 parts of the agglutinant and 1 part of the quick-drying agent. The repairing speed of the repairing material is high. A structure after being repaired by using the repairing material is solid. Service lifetime is long. The repairing material can be used without kiln shutdown, and does not need baking after repairing, thus greatly shortening the maintenance time of kilns and effectively improving kin strength. The repairing material is an optimal material for repairing kilns.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a repair material for quick repair of various kilns in the chemical industry. Background technique [0002] Various boilers and other kilns are used in the chemical industry and electric power fields. When these kilns fail and need to be repaired, they need to be shut down, and the production will be suspended for a long time. The shutdown of the equipment will cause a large loss to the equipment. , Suspension of production also brings greater economic losses to manufacturers. In order to reduce the loss, people start from various directions. From the repairing materials, castables and plastics are used for repairing. However, the use of these materials is limited, the construction is inconvenient, and it takes a long time to bake the kiln to restore Production greatly takes up the production time of the kiln, increases maintenance costs, and reduces corporate profi...
