Application of 2500 mesh chromium ore powder in the production of chrome-magnesia bricks:
In the production of chrome-magnesia bricks, 2500 mesh chromium ore powder is mainly used in the following aspects:
1. Improve density
Fine particle filling: 2500 mesh chromium ore powder has fine particles, which can effectively fill the pores in the brick body and improve density.
Reduce porosity: High fineness helps to reduce porosity and enhance the mechanical strength and corrosion resistance of the brick body.
2. Improve sintering performance
Promote sintering: Fine particles increase the specific surface area, help the diffusion of materials during sintering, and promote densification.
Reduce sintering temperature: High fineness particles can achieve good sintering at a lower temperature and save energy.
3. Enhance slag erosion resistance
Uniform distribution: Fine particles of chromium ore powder are evenly distributed in the brick body, improving the ability to resist slag erosion.
Chemical stability: Chromium ore powder has stable chemical properties and can effectively resist slag erosion.
4. Optimize physical properties
Improve strength: Fine particle filling and good sintering significantly improve the mechanical strength of the brick.
Enhance thermal shock stability: Uniform microstructure helps improve thermal shock resistance.
5. Improve process performance
Improve plasticity: Fine particles increase the plasticity of raw materials and facilitate molding.
Reduce cracking: Uniform particle distribution reduces the risk of cracking during drying and sintering.
6. Reduce costs
Reduce dosage: High-fineness chromium ore powder can reduce dosage without affecting performance and reduce raw material costs.
Improve yield rate: Optimizing process performance helps to improve yield rate and reduce scrap.
