Why the fire resistance of light burned magnesia powder is strong

Release date:2017-11-10 Author: Click:

Light burned magnesia powder is made from natural magnesite ore and calcined by high temperature shaft kiln. It is the raw material for brick making and the production of amorphous refractories. The finished products are used for steelmaking, EAF bottom and tamping.


Magnesite is mainly used for magnesite ore of more than 46%. Magnesite ore is calcined by high temperature shaft kiln and heated to 1400 - 1800 C. Mg (CO3) is completely decomposed to produce calfite and become hard reddish brown reburning magnesium. It has high refractoriness. It is an ideal raw material for manufacturing amorphous refractories. The products are used for steel-making open hearth, electric furnace bottom and tamping lining.

The refired magnesia Mill said the effect of sewage treatment in Magnesium Oxide, Magnesium Oxide can react with sewage to produce magnesium hydroxide, the powder form of Magnesium Oxide and sewage reaction first produce magnesium hydroxide, Magnesium Oxide and sewage reaction to produce magnesium hydroxide, while treating the harmful impurities in the sewage, the use of magnesium hydroxide It can be used as neutralizer. Magnesium hydroxide is alkaline and has good adsorption properties. It can be used as neutralizer for acid waste gas, wastewater treatment, heavy metal and organic waste liquid treatment. In recent years, it has been widely used in water treatment system.

When the magnesite is calcined at 1800, the carbon dioxide completely escapes, and the Magnesium Oxide forms a compacted block of the calcinate, weighing the magnesite (also called the sintered magnesium powder), which has a high refractoriness. Its main component is Magnesium Oxide, which is made from natural high-grade magnesite ore by flotation purification, light burning, fine grinding, high-pressure ball pressing and ultra high temperature oil shaft kiln calcining.

Dashiqiao Productivity Promotion Center Joint Universities and scientific research institutes, relying on the pilot enterprises of Liaoning Fenghua Industrial Co., Ltd and other pilot enterprises to set up the demonstration base of energy saving and emission reduction technology of reburning magnesium, integrate the scientific and technological innovation resources in various aspects of society, and jointly develop the energy saving and emission reduction technology of magnesia powder, forming a comprehensive, open and multi-functional function. Reburning magnesium powder industry, energy saving and emission reduction technology innovation service platform. The platform has carried out solid and effective work in the fields of technological innovation service, science and technology exchange service and science and technology training service. In organizing enterprises, universities and scientific research institutes to develop the technical achievements and the transformation of scientific and technological achievements, a large dumbbell shaped structure reburning Magnesium Oxide shaft furnace, multi point continuous rotary cloth machine, disc rotary force discharging machine, small dip angle cylinder seal belt pressure continuous unloader, and automatic crushing device in the furnace are prepared. Magnesium Oxide green production equipment; build an adult production line of 80 thousand tons reburning Magnesium Oxide demonstration.
