What is the purpose of reburning magnesia

Magnesite in heavy firing means that when magnesite is calcined at 1800℃, carbon dioxide completely escapes and magnesite forms a compact block of calcined magnesite, which is weighed and fired (also known as sintered magnesite). This magnesite in heavy firing has high refractoriness. Its main component is magnesium oxide, which is made of natural extra-grade magnesite by flotation purification, light burning, fine grinding, high-pressure pressure ball and ultra-high temperature oil calcined in vertical kiln.

Magnesium oxide is a basic oxide, has the basic oxide common, belongs to the cementing material. White powder (pale yellow is magnesium nitrided), odorless, tasteless and non-toxic, is a typical alkaline earth metal oxide magnesite. When calcined at 1800℃, carbon dioxide completely escapes and magnesium oxide forms a dense block of calcined magnesite, weighing magnesia (also known as sintered magnesite), which has a very high refractoriness. Its main component is magnesium oxide, which is made of natural extra-grade magnesite by flotation purification, light burning, fine grinding, high-pressure pressure ball and ultra-high temperature oil calcined in vertical kiln.

Mix magnesium oxide with magnesium chloride solution, add a little talc powder, quartz sand, glass wire, knot to form. It has a fire resistance of 400 degrees Celsius and a high energy of 1700 degrees. Heavy - fired magnesium, good sintering degree, uniform chemical composition, stable quality. Mainly used for steelmaking open hearth furnace, electric furnace sintering furnace bottom and ramming lining.

Magnesite is a kind of chemical substance, which means that when magnesite is calcined at 1800℃, carbon dioxide completely escapes and magnesium oxide forms a magnesite compact block.

This heavy - fired magnesium has a high fire resistance. Its main component is magnesium oxide, which is made of natural extra-grade magnesite by flotation purification, light burning, fine grinding, high-pressure pressure ball and ultra-high temperature oil calcined in vertical kiln.
