Main application:
Passivaiton spherical magnesium metal powder is used for desurfuration and deoxidation in the production of high-quality steel ,bring the sufur element of steel to be less than 0.004% . it is inreplaceable compare with other desururation in the usage of getting high-quality steel .to replace fe-si-mg master alloy in the production of ductile cast iron as nodularizer . For the oil industry to recover and accelerate pressure drilling and oil well into the late speed. In the chemical industry, the military industy, are effective dehydrating agent and oxidizer, it is also the magnesium alloy powder metallurgy materials.
Advantage of passivation spherical magnesium powder
As the desurfuration agent in the process of smelting iron ,it had been widely used worldwide ,advantage includes : less consumption ,short time processing ,more quickly reaction , less dropping of liquid fe temperature ,less sinter ,better effects of desurfuration and deep desurfuration
Specification :
Size 0.18-2mm (10-80mesh)
Size distribution :
2mm-0.85mm 10%-25%
0.85mm-0.50mm 40%-50%
0.5mm-0.40mm 15%-25%
0.4mm-0.21mm 5%-10%
Below 0.2mm 0-5%
Chemical composition
It looks dark grey or silver white ,shape is roundness or unequal roundness
Before passivation : mg content 99.95% min
After passivation : mg content 75%-94%
Loose density: more than 0.75 g/cm3
Burning point : 560℃—600℃
Fire retardant time :at 1000-1100℃ ,more than 15 s
