Performance optimization and future application prospects of chrome corundum bricks

Performance Optimization

Raw material optimization: Selecting high-purity, appropriate-size alumina and chromium raw materials can improve the quality and performance of chrome corundum bricks. For example, using high-quality fused white corundum and chromium oxide powder can make the brick body denser and stronger.

Additive improvement: Adding mullite can improve thermal shock resistance, and the appropriate amount is 25%-30%. Too much will reduce the volume density and compressive strength; adding andalusite can also improve thermal shock resistance, and the appropriate amount is no more than 18%. Its mullite reaction can reduce the apparent porosity, and the staggered columnar mullite can enhance the high-temperature flexural strength.

Process improvement: Accurately control the molding process parameters and use isostatic pressing and other methods to improve the density and uniformity of the bricks; optimize the sintering process and reasonably control the sintering temperature, time and atmosphere to make the brick structure denser and the performance better.

Surface treatment: Sandblasting, polishing and other treatments on the surface of chrome corundum bricks can improve surface quality, reduce porosity, enhance its wear resistance and erosion resistance, and meet high-end application requirements.

Application prospects

Deepening of traditional fields: In the metallurgical industry, with the development of metal smelting technology such as steel, the requirements for high temperature resistance and corrosion resistance of furnace lining materials are constantly increasing, and chrome corundum bricks will play a more important role; in the glass manufacturing industry, the trend of large-scale and high-efficiency glass furnaces is obvious. As a high-quality lining material, the market demand for chrome corundum bricks will continue to grow steadily.

Expansion in emerging fields: In the field of new energy, such as the solar photovoltaic industry, it can be used as the lining material of high-temperature sintering furnaces; in the field of nuclear energy, it is expected to become the shielding material and structural material of nuclear reactors. In the field of environmental protection, with the increase of environmental protection projects such as solid waste treatment and flue gas desulfurization, the use of chrome corundum bricks as lining materials for high-temperature incinerators and desulfurization towers will also increase accordingly.

Driven by technological innovation: With the continuous advancement of science and technology, the production technology of chrome corundum bricks will continue to innovate, and the performance will be further improved, thereby expanding its application in more extreme environments and high-precision fields. For example, chrome corundum brick products with higher strength, better thermal shock resistance and lower energy consumption are developed to meet the needs of high-tech industries such as aerospace, electronic information, etc. for high-performance refractory materials.
