Product introduction:
Corundum mullite brick products are made of imported plate-shaped corundum and high-purity fused corundum as the main raw materials, using advanced super micro-powder addition technology, after mixing, molding, drying, and high-temperature firing in a shuttle kiln. During the production of corundum mullite bricks, a certain thickness of heat insulation layer material was designed and manufactured on its non-working surface according to the use conditions.
Features:
1. Corundum mullite brick has the characteristics of high refractoriness and good thermal shock stability
2. High temperature strength, excellent corrosion resistance and strong slag resistance
3. With the characteristics of small expansion coefficient, low creep, and anti-stripping, corundum mullite bricks are suitable for use in high-temperature kilns under various conditions Product

Usage:
Corundum mullite bricks are widely used in high sintering of zirconia ceramics, fluorescent materials, electronic ceramics, magnetic materials, ceramic powders, gasification furnaces in the petrochemical industry, secondary conversion furnaces for synthetic ammonia, carbon black reaction furnaces and high-temperature kilns in the glass industry. and other equipment.
Zhenjin Company was the first in China to develop a chrome-free and environmentally friendly magnesia-iron spinel brick. This product is based on magnesia and iron-aluminum spinel as the main materials, and by introducing active spinel into the matrix components, The product forms a network-like spinel structure during the sintering process. Our products are widely recognized in the cement industry.What are the characteristics of magnesia-iron spinel bricks?
