When researching electric smelting zirconium corundum brick moulding production, should pay special attention to the study of fused corundum brick gating processes of crystallization kinetics and the creation theory. Casting of fused bricks production process can be divided into three phases: melts of advance preparation and model; melt casting and molding the oven; heat treatment of castings. Electric smelting zirconium corundum brick is the main difficulty of heat treatment process of its crystallization, this is a complex physical properties of different kinds of complexes, and in terms of physical, chemical, and thermal phenomena linked to each other. Crystallization and structure formation of casting material through the detailed analysis of the process of identifying, "casting-model" system that fully describes the process of thermal phenomena in substance. Models in the cast when the electric smelting zirconium corundum brick melts, heat near the surface due to the fused bricks, visible in some sections to a low temperature. Cast when the electric smelting zirconium corundum brick to a model of cooling speed indicated by a temperature gradient. In the case of no external factors, temperature gradient depends on the size of Thermophysical properties of fused bricks. Fused bricks melt cold start on a model surface; supercooled layer thickness too hot, and the speed is determined by the temperature gradient, with the model surface gradually fused bricks melt crystallization, starting down a layer of cold. The layers melt gradually cooled, cold level starting from the fused brick surface, according to the temperature gradient is accordingly reduced. Electric smelting zirconium corundum brick can be seen as combination of many thin layers, each layer of the cold can be considered fixed.
