MAGNESITE ORE

The mining of raw magnesite is mechanized combining with operation of down hole drills, electric shovels, and

heavy-duty tippers. The annual capacity of mining and stripping is more than 6 million tons. Magnesite ores up to the grade,

after being crushed, screened, and selected according to different specifications required, are fed to following processes

of calcining, dead burning, electric fusing or directly sold to customers.

LARGE CRYSTAL FUSED MAGNESITE

Large Crystal Fused Magnesite is produced in electric arc furnace by fusing 91%-92% MgO with 0mm-3mm size, which is featured with high

purity, big crystalline, dense structure, good slag resistance, and good stability against thermal chocks. It is a good high-temperature

electrical insulating material as well as major raw material in making high grade magnesia brick, magnesia carbon brick,

and magnesia monolithic refractories.

FUSED MAGNESITE

Fused Magnesite is produced in electric arc furnace by fusing >47% raw magnesite, which is featured with

high purity, big crystalline, dense structure,good slag resistance, and good stability against thermal chocks. It is a good high-temperature

electrical insulating material as well as major raw material in making high grade magnesia brick, magnesia carbon brick,

and magnesia monolithic refractories.

MIDDLE-GRADE DEAD BURNED MAGNESITE

Middle-Grade Dead Burned Magnesite is produced from Caustic Calcined Magnesite with 95% MgO content by pressing

briquette and calcining in high temperature shaft kiln. The products are sintered well and crystallized.

HIGH-PURITY DEAD BURNED MAGNESITE

High-Purity Dead Burned Magnesite is made from finely selected super grade-A raw magnesite through processes of floatation concentration,

calcination, milling, briquetting, and sintering in ultra-high temperature oil shaft kilns. It is the

excellent material for making magnesia brick and magnesia monolithic refractories.

CAUSTIC CALCINED MAGNESITE BRIQUETTE

Caustic Calcined Magnesite Briquette is made available through briquetting calcined magnesite powder. It is the proper material to support the Nitrogen Converter

Lining Protection Technology by Slag Splashing so as to enhance the service life of steel converters.

FIRE CLAY

Fire Clay is a mixture of refractory clay and clay clinker (or waste clay brick). It is also knowned as refractory fire clay.

Clinker can be substituted partly or entirely by sand, silica, lime mudstone and so on. Sometimes a small amount of sodium silicate is

added to form an adhesive.Building kilns are used as cementing materials for laying clay refractory bricks.

REPAIRING MIX FOR CONVERTER

The main raw material is high quality magnesite．By adding the modified

pitch, flowing agent, sintered agent and other special additives，

the product has good ductility，fast sintering under high-temperature. And

it is suitable for repairing large area in the front and back of converter. It is also suitable for repairing the steel-tapping hole.
