Usage: Mainly used for desulphurization pretreatment in molten iron Appearance: Silver-gray spherical granules, with 0.5-1.6mm diameter (can be changed according to user's request ) Rests angle (IC): Smaller than 26° Density of relax stack: 1.0g/cm3 Burning point: In average, not lower than 600 ° C. Burning-resistant time at high temperature: Not less than 15---18 second at 1000° C Production technology characteristic: Machine-cutting processed, then sphericizing and coating processed Package: Double layer sealed package. The inner layer of the package is a polyethylene film and the outer one is a flexible collecting bag. Each bag is with net weight of 1, 000 kilograms. According to the user's request, packaging materials may also be provided by users Transportation cautions: Water-proof and moisture-proof are needed, but fire-proof and explosion-proof are not necessary. When road or railway transportations are implemented, trays are needed under the packing sacks and covers too, on the top of them as shelters from rain, snow etc. Containers must be used for marine transportation Storage: Should be separately put on trays, in dry and well ventilated storehouse with roof to avoid water contact Warranty time: Six months after delivery.
Physics and chemistry targe Chemical composition % ( Weight ) Size composition % ( Weight ) Magnesium content ( mg ) Coating 0.5 __ 1.6mm Irregular granularity ≥ 92 ≤ 5 92% ≤ 8 Notice: Granules should not stick with each other and with other mechanical impurities. Irregular granularity indicates: In length more than 3mm acicular granules or granules with long tails Rest angle (IC): Smaller than 26° Density of relax stack: 1.0g /cm3 Burning point: Not lower than 600 ° C in average Burning-resistant time at high temperature: Not less than 15-18 second at 1, 000 ° C. Magnesium content in granules before coating: 99.95%. Content of magnesium after the coating: 92-98% according to user's request.
