Fused cast AZS block concrete production process is as follows:
1. Preparation of molten zirconia corundum materials
Excellent performance of high purity zirconium corundum materials, weighing mixed together, so that the raw material properties are fully utilized. Materials, weighing mixed together, so that the full use of raw material properties.
2. Molten zirconia corundum
Will be combined with the molten zirconia corundum material into the electric arc furnace with automatic control, under the best conditions of melting. With single-phase or three-phase arc furnace melt temperature should be moderate, bulk low temperature will not form a highly uniform melt, easy to form porous body castings, so that the melt castings produce pores and cracks, shrink a corresponding increase in product formation Of the contraction chamber.
Molten material specially designed injection mold products. Casting the dense structure and the use of good performance of the fused brick. Through the appropriate hot-melt casting, cast zirconium corundum bricks shrink cavity concentration, dense area thickness increases, the product density also increases. However, when the superheat is high, although the melt density increases, the product forms cracks and large shrinkage.
Casting good bricks and slow cooling, the zirconium corundum block from the crystal growth to form the best structure.(http://www.fusedcastazs.com/fused-cast-azs-block/1.html)
5. Surface treatment
The use of precision machining equipment, so that products Fused cast AZS block processing in line with the design requirements of the precise size. Mechanical processing can improve the quality of molten brick, extending its service life.
Each cast AZS block is a strictly visual inspection and shall be carried out in accordance with the contract standard.
7. Physical and chemical analysis
According to the requirements of the contract control engineering, the physical and chemical analysis of the molten brick.
