Capacitance magnesia brick and magnesia brick are distinguished

Cent of magnesian chromic brick is, common magnesium chromic brick,

Combine magnesian chromic brick directly

, combine magnesian chromic brick partly, chromic brick of electric frit magnesium, electric frit combines magnesian chromic brick partly, avoid brick of the chromium that burn magnesium, and magnesian chromic brick and

Combine magnesian chromic brick directly

distinction depends on 1: Contain magnesia (raw material) purity 2: Firing temperature, firing temperature is in common magnesium chromic brick ℃ of 1550 ℃ ~1600, firing temperature is in direct magnesium chromic brick 1700 ℃ above, because its are when 1700 ℃ above, magnesian chromic brick

Microstructure

Produce change,

Square magnesian stone

Be united in wedlock directly with chromic ore, call so

Combine magnesian chromic brick directly

. Combine magnesian chromic brick directly each respect function all excel is common magnesian chromic brick.

Firing magnesia brick is used high grade

Agglomeration magnesia

For main raw material, serve as bond with pulp. After shaping via mixing refine and high pressure, in the high temperature of 1550 ℃ above

Channel kiln

In firing. Have good

Thermal stability

, fight erode and fight flake function. Use extensively at furnace of converter, electric arc to wait

Industrial kiln furnace

Make lining fireproof material.

Electric frit magnesia brick has bricky system structure compact, mechanical intensity is high,

Matter content is little wait for an advantage, basically use at the accumulation of heat of large glass kiln

The high temperature area of the room.

Magnesia brick (Magnesite Brick) magnesian content is in the 90% above, alkalescent and fireproof material that gives priority to brilliant photograph with Fang Mei stone

Can divide commonly for agglomeration magnesia brick (say again firing magnesia brick) combine magnesia brick with chemistry (say not to burn magnesia brick again) two kinds big. Purity and firing the magnesia brick with high temperature, because grain of square magnesian stone is contacted directly, call direct union magnesia brick; The brick that makes for raw material with electric frit magnesia calls magnesia brick of electric frit recombine.

Magnesia brick has taller fireproof degree, function of very good broken bits of alkali resistance sex, loading bate begins temperature tall, but heatproof shake performance is poor. Agglomeration magnesia brick is raw material with making bricky magnesia brick, via smashing, burden, mix practice, after shaping, in 1550 ～ the high temperature of 1600 ℃ falls firing, high pure of goods firing temperature is in 1750 ℃ above. Irrigating magnesia brick is proper chemical bond is added in magnesia, via mixing refine, shape, dry and make.

Firing magnesia brick uses magnesia of high grade agglomeration to be main raw material, serve as bond with pulp. After shaping via mixing refine and high pressure, firing in the kiln of high temperature channel of 1550 ℃ above. Have good thermal stability, fight erode and fight flake function. Use extensively at the industrial kiln furnace such as furnace of converter, electric arc to make lining fireproof material.

Electric frit magnesia brick has bricky system structure compact, mechanical intensity is high, matter content is little wait for an advantage, basically use at the accumulation of heat of large glass kiln

The high temperature area of the room. Electric frit magnesia is the course fuses and make for raw material with high grade magnesia, english name Fused Magnesite. By magnesium of magnesite, water mine or the oxyhydrogen that extract from inside seawater change magnesium to be become via high temperature to calcine. Fight to hydrate ability strong.
