Silver White Spherical Passivation Magnesium Granules

Silver White Spherical Passivation Magnesium Granules
Product Detailed
Silver White Spherical Passivation Magnesium Granules: Less consumption , short time processing, fast reaction etc.

As the desulfuration agent for smelting steel and iron, passivation spherical magnesium powder has been widely used in developed countries. It is necessary for steel and iron enterprises to produce qualified and special type steel.

Specification of Silver White Spherical Passivation Magnesium Granules:

2-0.21mm(10-65 meshes), 0.85-0.18mm(20-80 meshes), 0.99-0.21mm(16-65 meshes), 0.85-0.21mm(20-65 meshes), 0.85-0.30mm(20-50 meshes), detailed mixing proportion is according to the requirements of clients.

Physical, Chemical Property and Technique Standard

The passivation magnesium powder looks grey and white, and the granule shape is roundness or unequal roundness.The burning point of passivation magnesium powder is between 560-600°C.The fire retardant time of passivation magnesium powder is not shorter than 15 seconds at 1000°C.The passivation magnesium powder should not contain impurity and agglomeration, but there can be a little passivation layer powder.

Checking Rule of Mg Granules

Using eyes to see the color, shape and other appearance of the passivation magnesium powder.Content of granularity, loose density, Mg, CaO, CaF2, MgO, P, S and H2O is checked according to set standards.The burning point and fire retardant time are checked according to special equipment and method.The sample is batched (2 tons/batch).

Usage and Effect

During production and testing period, spraying and blowing equipment processing of magnesium based desulfuratioin agent must be provided.Mg based desulfuration agent is generally mixed used with CaO based desulfuration agent, the mixing proportion is: 10-25%, 90-75%, a small quantity of carbide powder can also be mixed.Input of Mg based desulfuration agent is 0.6-1.0kg/T rion.Pay attention to sampling and measuring temperature before and after spaying and bellowing. Take slag-off in time when spraying and blowing are complete.The best temperature of magnesium based desulfuration agent is around 1280±30°C.After blowing in Mg based desulfuration agent, temperature of molten iron will drop 10-20°C.Spraying and Bowing Speed: 40-60kg/min.Spraying and Blowing Methods:


The products should be clearly indicated with quality certificate, names of parties, products name, specifications, weight, chemical components, delivery and receiving responsible person names.If there is any splashing powder of the products, then clear it up.Prepare fireproof sand at the storehouse and operation spot; It is not allowed to put off the fire with water and extinguisher.For other items, which are not covered here, some appropriate measures will be taken according to operation procedure.
