Product Description:


Magnetic Chrome Brick
ISO9001:2000 Certificate

Burnt magnesia-chrome bricks are made from high quality mag-nesia and chrome concentrate, cr2o3 content can be adjusted according to different requirements. The bricks have good thermal stability and high temperature performance, and are widely used in cement kilns and non-ferrous rnetal metallur-gical furnaces and so on. High temperature burnt directly bonded magnesia-chrome bricks, semi-rebonded magne-sia-chrome bricks and rebonded magnesia-chrome bricks are made from low impurity raw materials. All or part of raw ma-terials are preburnt or electro fused. The best proportioning, high pressure moulding, ultra high temperature and good vol-ume stability. The bricks are widely used in large cement ro-tary kiln, and secondary refining units such as RH, VOD, AOD furnaces, non-ferrous metal met-allurgical furnaces, glass tanks and so on.

Q:What matters should be noticed when using clay refractory bricks in a glass kiln?
There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic
Q:is refractory brick used around the mechanism flue?
Q:What raw materials are used for making refractory bricks
That is silicon aluminum refractory brick/, it can be divided into five types:thermal insulation refractory brick, alkaline series refractory brick, refractory brick containing zirconium, carbonaceous refractory brick/. Refractory bricks are divided according to the ingredient of refractory. Refractory bricks are generally made from refractory clay (kaolin) or other refractory materials.
Q:When the coal-fired steam boiler is built, it is necessary to build a common red brick between the refractory bricks. May I ask what is the requirement for this common red brick?
Q:Do refractory bricks resist corrosion and sulfur?
There are anticorrosion and acid proof refractory bricks
Q:What is the best color of refractory brick
Date red is better.
Q:what kind of refractory brick is suitable for 1300 degrees converter?
The furnace cap tapping shaft part should use MgO-C brick with high slag resistance and thermal shock resistance, the steel side can be slightly thin, bottom carbon content may be appropriate less.
Q:What is the refractory brick in silicious model?
Adding appropriate amount of mineralized agent to promote the transformation of quartz in the body into phosphorus quartz. Smaller coefficient of thermal expansion. Also used in high temperature bearing part of hot blast stove and acid open hearth furnace, refractory materials and ceramic kiln, kiln vault and other load-bearing parts, thermal shock resistance variation. High temperature strength. the glass furnace is burnt in 1430 to 1350 degrees Celsius in the reducing atmosphere. use natural silica as raw materials. True density 2. more than 93% of silica content. generally there is no crystal type transformation above 600 degrees celsius. With acid slag erosion and sediment chamber regenerator performance, soaking furnace, open hearth furnace. there is more crystal type transformation below 600 degrees celsius. mainly used in coking chamer of coke oven and partition of firebox. acid refractory material made of high thermal shock resistance, large volume change, square quartz and a small amount of residual quartz and glass box . Long term use at high temperature without deformation
Q:What are the differences between thermal insulation bricks and refractory bricks?
Thermal insulation brick is thermal insulative; refractory brick is high temperature resistant.
Q:The stove which made of refractory bricks and fireclays will produce cracks after being used. How to solve this problem?
The use of low expansion materials will be better. But as for the stove, the appearance of crack is attributed to the selected materials or the environment. And when the temperature is not high, there still seems to be crack, so through expansion joint reservation, not allowing itself to crack
