Corundum mullite brick It is the ability of refractories to resist friction, impact and grinding of hard materials. Therefore, the higher the wear resistance is, the better the performance of refractories. We can analyze the practicability of corundum bricks in wear and erosion environment through wear resistance.
1. according to the structure, working characteristics and movement conditions of the furnace cellar, and analyzing the causes of the material damage, the suitable refractory material is selected. Accurately understand and grasp the temperature changes of various parts of the material, carefully observe the material to prevent all kinds of destructive effects.
2. be familiar with the chemical composition and physical and working properties of materials, so as to give full play to the characteristics of materials.
3., make the materials of various parts of the furnace properly cooperate, so as to avoid the mutual damage of materials, and take measures to ensure the overall life span.
4., to meet the above basic principles, we should solve the resources and costs as much as possible. We can choose materials with low price and transport costs, and vigorously develop recycling to reduce costs.
The use of corundum rate is very low, it is difficult to meet the requirements, and the overall strength and poor construction capacity, can not meet the industry's diversified environmental steel. In the future, we should vigorously strengthen our own fire resistance, use high quality and serve the most.
Corundum mullite brick The casket is used for loading materials and sintered materials at high temperature. The thermal shock is higher than 99 ceramic crucible, and can be used at 1700 degree high temperature.
Corundum mullite brick Casket is a powder sintered material made of phosphorus, lithium and rare earth. It has high refractoriness, thermal shock resistance, high temperature resistance, good corrosion resistance, low slag permeability, low permeability, low creeping, no milk, no cracking, and high stability. All these are high temperatures for oven tools, so as to adapt to many kinds of atmospheric conditions used in high temperature furnaces. Applied to alumina ceramics and zirconia ceramics and fluorescent materials, powder metallurgy, electronic ceramics, magnetic materials, high temperature sintered ceramic powder.
