Application of Centrifugal Cast Pipe Technology
Abstract
The raw ore of Daguan Diatomite Company, clay accounts for 80% of the reserves in the mining area, and the diatomite products processed and produced have the characteristics of low burning vector, light specific gravity, large specific surface area, uniform particle size distribution, heat insulation, strong adsorption, high melting point, good thermal stability, small gas emission, porous structure, etc. Used in hot mold coating, under the action of high temperature molten iron, it is released from the coating raw materials, and the gas precipitated from the unsolidified molten iron can be stored in the porous coating to prevent the formation of gas pits, pinholes and other defects on the outer surface of the cast pipe, so as to obtain high-quality products.
