Hard Burned Magnesite

Introduction

It is produced by sintering 46%-46.5% content magnesite in iron shaft kiln.

It has high MgO content,usually between 90-93%, can be used as raw material to produce ordinary magnesia bricks and amorphous refractory materials. Heavy burnt magnesite is mainly made of magnesite with 46% content, which is calcined at 1600 -1800 ℃ by one layer of coal and one layer of magnesite in iron sheet kiln. Two tons of ore produce a ton of heavy burnt magnesia products in the production process. The main color of re-burned magnesia products is hard reddish brown, the characteristics of re-burned magnesia products featured with very high fire resistance.

It can be used for magnesia bricks, magnesia-alumina bricks, magnesia-chrome bricks, spraying materials, castables, dry materials, smear materials, furnace filler, asphalt, casting, fire and insulation materials, flux accessories, electrical steelmaking furnace, heating furnace, rotary furnace, steelmaking, furnace bottom and lining.
