Пассивации spheril порошок магния

Passivation spherical magnesium powder is usedfor desulfuration and deosidetion in production of tine steel, bringing the sulfur element of fine steel to be less than 0.004%, as a dehydrant, it is not replaceable to improve fine steel quality exploitation, in production of ductile cast iron, it is a kind of spheroidizing instead of iron-silicon-magnesium middle alloy. For petroleumextraction, it can resume or accelerate the speed of the pressure drilling hole and oil well. Passivation spherical magnesium alloy powder, meanwhile, it is a kind of metallurgical material. Chemical components: magnesium content is over 99.5% before passivation, the magnesium content is around 75% to 94% after passivation, Specification: 10-80 meshes (granule 2-0.18mm), the mixing propotion could be made according to the demand of the clients. Product shape: roundnessor unequal roundness Product color: dark grey or silver white Loose density: 0.75 to 0.94g/cm2 Average burning point:560-600centigrade Flame retardant time:1000-1100centigrade not shorter than 15 seconds.
