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.
Magnesium alloy is it is with magnesium base the alloy that joins other element composition. Its characteristic is: Density is small (1.8g/cm3 magnesium alloy is controlled) , taller than intensity, stretch model amount is large, medicinal powder heat is good, disappear shake sex is good, bear concussion load ability is greater than aluminium alloy, be able to bear or endure organic matter and it is good to corrode function alkalinely. Main alloying element has aluminous, zinc, manganese, cerium, thorium and a few zirconium or cadmium. Use at present the widest is magnalium alloy, it is magnesian manganese alloy and alloy of magnesian zinc zirconium next. Basically use at aviation, spaceflight, carry, the industrial department such as chemical industry, rocket. The lightest metal is in practical metal, magnesian proportion is aluminous 2/3 about, it is the 1/4 of iron. It is the lightest metal in practical metal, high strenth, tall tigidity.
Magnesian chromic brick is it is bases with MgO and Cr2O3, this kind of brick is fireproof degree tall, high temperature strength is great, fight basic slag aggressivity strong, thermal stability is excellent, to acid slag also certain adaptability is in the application in high temperature industry is wide now, but the meeting when Cr3+ of the part in magnesian chromic brick is used is changed into Cr6+ , generate K2CrO4 to wait virulent with the compound that causes cancer, use in the cement kiln that so the use of magnesian now chromic brick is building an industry especially had been asked to be changed without chromium, cement finished product detects cannot contain chromium.
This product
Environmental temperature
Highest allow 1700 ℃ , in 1500 ℃ ～ the bear condition of 1650 ℃ falls, have high strenth, Gao He to fight the characteristic of shake of alkaline land, high fever softly, high, hang alkalescent kiln skin easily. More chromic than the congener product magnesium that international uses brick has the huge advantage of environmental protection and macrobian life, have powerful
International market
