Correct using method make refractories have anti damage ability

Supporting the development of refractories for the clinker rotary kiln each work with the different mining conditions, targeted to different anti damage of refractory materials, andconsidering the basic matching problem with various working lining life, reduce maintenance times to stop the kiln, each work with lining, the anti damage of independent and phase the purpose of matching cycle. Lining material preheating with good chemical stability, alkali erosion leaf wax stone brick and strong, the pyrophyllite using low alkali and high alkali bricks siliceous raw material, the raw material made of, whether or not to burn the Chengdu firing with anti alkaline strong, but the strength is high, nearly doubled than clay brick life.

The industrial trials in Xinmi Changxing Refractories Co., and recommended for coke oven chamber wall three hot repair methods: flame spraying; ceramic welding using oxygen; theexothermic material (heating material) to repair. The process is: with the help of the principle of common heat generated to form a protective layer on the surface of masonry of refractory material to repair the surface.

Flame gunning method of flame gunning refractory products, powder particles melt in the liquid or gaseous fuel to the flame, and was sent to the surface to be repaired. The masonry is nozzle flame of heating, so using this method without special restrictions on the temperature, but also can be used to refractory powder cheaper to obtain high quality spraying layer. The principle of the ceramic welding method is added to the material of strong oxidant (exothermic material: aluminum, silicon etc.). Wind transport by means of oxygen jet flames, oxidant and refractory powder to the surface to be repaired.
