Foundry refractory production process introduction

Foundry refractory refers to the products that are cast into certain shapes after the raw materials and batch materials are melted at high temperature. There are two melting methods: electrofusion and thermite. The electrofusion method is to melt the batch material in an electric arc furnace or a resistance furnace. The aluminothermic method uses the heat released by the aluminothermic reaction to melt the batch material. The electrofusion method is the main method for producing fused cast refractories.

The production process of foundry refractory:
Production process: Raw material preparation-processing-coordinated processing-melting-casting molding-heat treatment-mechanical processing. There are many types of fused cast refractory products, the most widely used is fused cast zirconia jade bricks. Other fused cast products include: fused cast mullite bricks, fused cast zirconium mullite bricks, and fused cast products made of quartz, magnesia, spinel and forsterite. Compared with sintered products, foundry refractory products have the following characteristics: very dense products, less air cells L, high density, high mechanical strength, high temperature structural strength, high thermal conductivity, and good slag resistance.
