The furnace bottom refers to the lowest part of a high-temperature industrial furnace, which usually bears the heavy pressure and high-temperature corrosion of fuel and materials. There are several reasons for using high alumina bricks as furnace bottom material:
1. High alumina bricks have excellent fire resistance and high temperature stability, are not easy to soften or melt in high temperature environments, and can withstand the effects of factors such as thermal shock and mechanical impact.
2. High alumina bricks have good corrosion resistance, especially against acidic media, and can effectively prevent the furnace bottom from being corroded by acidic substances and causing damage.
3. High alumina bricks have high mechanical strength and hardness and can withstand the heavy pressure and extrusion of the furnace bottom to avoid cracks or collapse in the furnace bottom.
4. High alumina bricks have excellent insulation properties and can effectively isolate the heat exchange between the furnace bottom and the surrounding environment, improve the thermal efficiency of the furnace and save energy.
In summary, using high alumina bricks as furnace bottom materials can effectively improve the wear resistance, corrosion resistance, mechanical strength and insulation properties of the furnace bottom, thereby extending the service life and stability of the furnace bottom. When selecting high alumina bricks, their physical and chemical properties, mechanical properties, fire resistance and other indicators should be comprehensively considered based on the actual situation to ensure that they can meet the needs of industrial production.
