CHROME FLOUR Main uses of chromium ore powder
1. Manufacturing stainless steel and alloy steel: Chromium ore powder is one of the important raw materials for manufacturing stainless steel and alloy steel. The chromium content in stainless steel is usually between 12% and 30%. The addition of chromium ore powder can improve the corrosion resistance and wear resistance of stainless steel.
2. Manufacturing refractory materials: Chromium ore powder can be used to manufacture high-chromium refractory materials, which are mainly used for internal coatings of high-temperature furnaces and furnaces, such as steel, cement and other industries. The addition of chromium ore powder can enhance the high temperature resistance and corrosion resistance of refractory materials.
3. Manufacturing of pigments and coatings: Chromium ore powder is an important mineral pigment, mainly used to manufacture green pigments and chrome yellow pigments. At the same time, chromium ore powder can also be used in the formulation of coatings. Adding an appropriate amount of chromium ore powder to the coating can enhance the color and weather resistance of the coating.
4. Manufacturing plastics and rubber: Chrome ore powder can be used to manufacture plastics and rubber, and is widely used in industrial products such as automobiles, electrical appliances, and building materials. Adding an appropriate amount of chromium ore powder to plastics and rubber can improve the strength, hardness and wear resistance of the materials.
5. Manufacturing electronic materials: Chromium ore powder can be used to manufacture semiconductor materials, magnetic materials, etc. in electronic materials. Adding an appropriate amount of chromium ore powder to electronic materials can improve the material’s conductivity, magnetism and high temperature resistance.
