MAIN APPLICATIONS
Chrome flour in manufacturing stainless steel and alloy steel
The abrasive resistance and corrosion resistance of stainless steel and alloy steel can be improved through adding certain chrome flour
Chrome flour in refractory industry
Chrome flour usually is used for making high chrominum refactory bricks which are used in internal coating of high temperature furnace and stove.
Chrome flour in pigment and coating
Chrome flour is a main mineral pigment,to produce green pigment and chrome yellow pigment.besides,chrome flour can be added in coating to increase the color and weather ability of coating.
Chrome flour in plastic and rubber
To increase plastic and rubber’s intensity,hardness and abrasive resistance,chrome flour will be added in plastic and rubber.
Chrome flour in electronic material
Chrome flour can be used in electronic material such semiconductor materials and magnetic material,adding maderate chromite powder can enhance electrical conductivity,magnetism and high-temperature resistance.
