refractory, k and π are constant. Therefore, magnesia-chrome brick has a better slag permeation resistance performance than alumina-chrome brick. Although MgO in magnesia-chrome brick could form the substitution solid solution with FeO to prevent slag permeation, the magnesia-chrome brick is hardly to resist the corrosion of ferronickel slag with
Magnesia chrome brick mainly used in metallurgical industry like furnace top of open hearth furnace, electric kiln and other ferrous furnace. Uhp electric arc furnace's wall which part that touch high temperature uses fused magnesia chrome brick, high erosion area of refining furnace adopts magnesia chrome brick made by composite materials, non-ferrous fasting melting furnace's high erosion
201836The performance of any refractory always depends on the working environment. As far as Mg-Cr bricks are concerned, they are mostly used in converters and furnaces of non-ferrous industries like copper, zinc etc. and also in some areas of secondary
Refractory Brick for sale, an excellent kiln refractory material, is briefly called fire brick that has certain shapes and sizes. Refractory brick includes different types of burnt brick, unburned brick, fused cast brick and refractory insulating brick according to different manufacturing processes.

Magnesia chrome brick Firebrick contains magnesia clinker and chromium ore, and its chemical component has more than 50 vol% of MgO. Used for rotary kiln furnace, AOD furnace, VOD ladle, RH, etc. Magnesia dolomite brick
2015728Refractories in different areas of a glass furnace suffer different operating environment. So different types of refractory are used in the different parts of the glass furnaces. Crown Refractories. Crown of glass furnaces are subjected to long-term thermal attack and chemical corrosion due to alkali vapor.
The application of dense magnesia bricks contributes to increased durability of the lining in metal manganese and manganese slag producing furnaces. The life of magnesia brick linings with an 11 to 13% porosity amounts to 45 days. The employment of large-size bricks hightens the resistance of the furnace bottom.
The forging furnace is used for preheating billets and ingots to attain a 'forge' temperature. The furnace temperature is maintained at around 1200 to 1250 oC. Forging furnaces use an open fireplace system and most of the heat is transmitted by radiation. The typical load is 5 to 6 ton with the furnace operating for 16 to 18 hours daily.
There are 428 sintered magnesia suppliers, mainly located in Asia. The top supplying countries or regions are China, Singapore, and South Korea, which supply 99%, 1%, and 1% of sintered magnesia respectively. Sintered magnesia products are most popular in Netherlands, Pakistan, and Turkey.
Fire Clay & High Alumina Bricks. We manufacture and export Fire Clay & High Alumina Bricks. Alumina is an excellent engineering ceramic, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.
High Alumina Bricks Insulation Higher Thermal Load Low Thermal Conductivity, good mechanical strength. Silica Insulating bricks Repair Alkali Vapor Corrosion. Good Thermal Shock & Corrosion resistance Fused Silica bricks, Zircon based Ramming &Patching masses Refractories for Different Parts of Glass Tank Furnace
for various furnaces and kilns due to their superior properties. Magnesia bricks when compared to other type of refractories, there exists a great concern regarding their vulnerability during exposure with water vapour. Hydration of Magnesia (magnesium oxide or periclase Magnesia) in refractory material occurs when the material comes into
They are used for instance for building cooking chamber in wood fired ovens, for creating fireplaces, all sorts of fire boxes and wood heaters' lining, linings in a small or the hugest industrial furnaces, you name it. Fire clay bricks are very heavy/dense having low porosity and even on various re-heating, and under continuous heat, they
What Is Magnesia Alumina Spinel Brick Used For. Magnesia-spinel bricks are widely used in refractory materials, steel smelting, transition zone of cement rotary kilns, glass industrial furnaces and lime kilns. The service life of magnesia-spinel bricks in the cooling zone and transition zone of the kilns is twice that of magnesia chrome bricks.

Refractory Products and Applications. Because of their high temperature stability, refractory products serve as essential parts of heating furnaces, reactors and transport vessels that are often exposed to temperatures well above 1,000°C and environments that are corrosive, erosive, abrasive and/or thermal-mechanically stressed.
However, a magnesia-MK brick would be extremely expensive to manufacture and, furthermore, undesirable for environmental reasons.17, 18 A workable and realistic alternative for the investigated top-grade magnesia-chromite brick in the slag line of VOD ladle linings is not straightforward, due to the extremely harsh conditions imposed on the lining.
