Strengthen the heat, on the other hand reduces the round with the heat conduction from the lime kiln body, making the round with the outer edge of the temperature difference is smaller. When the lime kiln thermal changes in the system, its temperature change is not large, thus reducing the tire temperature stress. Blank casting. Rotary kiln spherical tile material is used mostly HT200. Our country most factory production blank in ordinary sand mold casting, such low cost, easy to operate; But the casting defects, such as sand holes, porosity, shrinkage and crack, etc. In order to improve casting quality, adopt the resin sand molding effect is remarkable. The casting of the blister, porosity, shrinkage and crack defects of castings have greatly reduced the risk, but the cost is high. When casting raw materials of good quality, the proper casting process, the resin sand molding processing finished spherical tile structure compact, the surface roughness is low, the appearance is bright and clean, the coloring deep inspection, and the percent of pass is 95%. In addition, the blank resin sand modelling of another advantage: spherical tile lumen sand cleaning is convenient and feasible.
lime kiln operation, the wheel with a lime kiln to produce relative sliding along the weeks to will cause wear and tear, when the plate play a role in the protection of the lime kiln. In order to ensure the outer circle of the tire and lime kiln design gap, and their mutual good
