Magnesium powder is calcined from natural magnesite by high temperature shaft kiln. It is the raw material for brick making and unshaped refractory production. The finished products are used for steelmaking, bottom of electric furnace and ramming lining.
Magnesium powder for reburning is mainly composed of magnesite ore with a content of more than 46%. Magnesium ore is completely decomposed into periclase when calcined in high temperature shaft kiln to 1400-1800 (?) C. It becomes hard reddish brown magnesia with high refractoriness. It is an ideal raw material for the production of amorphous refractories. Its products are used in open hearth, bottom of electric furnace and ramming lining.
Reburning Magnesium Powder Plant said that sewage treatment plays a role in magnesium oxide. Magnesium oxide can react with sewage to produce magnesium hydroxide. Magnesium hydroxide first reacts with sewage to produce magnesium hydroxide. Magnesium hydroxide reacts with sewage to produce magnesium hydroxide. At the same time, harmful impurities in sewage are treated. Magnesium hydroxide can be used as a neutralizer. Magnesium hydroxide is alkaline. It can be used as neutralizer for acid-containing waste gas, wastewater treatment, heavy metals and organic waste liquor treatment, etc. In recent years, it has been widely used in water treatment system.
Dashiqiao Productivity Promotion Center, in conjunction with universities and scientific research institutes, relying on pilot enterprises such as Liaoning Fenghua Industrial Co., Ltd., has established a demonstration base for energy-saving and emission-reduction technology of heavy-burned magnesia, integrated scientific and technological innovation resources from all sectors of society, jointly developed energy-saving and emission-reduction technology of heavy-burned magnesia powder, and formed a comprehensive, open and multi-functional energy-saving and emission-reduction technology innovation service for Platform. The platform has carried out solid and effective work in technology innovation service, science and technology exchange service, science and technology training service, etc. Organizing enterprises, universities and scientific research institutes to carry out technical research and transformation of scientific and technological achievements, we have developed large dumbbell-shaped magnesium oxide shaft furnace, multi-point continuous rotary distributor, disc rotary teeth strong discharger, small inclined angle column sealed continuous discharger with wind pressure, on-line automatic crushing device for the production of magnesium oxide with high efficiency, and built an annual output of 80,000 tons. Demonstration production line for reburning magnesia.
