Description:
It is made with sintered magnesia and refractory level chrome ore as raw materials. The space between refractory grains is bonded with silicate. The domestic so called magnesia –Chrome bricks .
The refractoriness of magnesia chrome bricks are more than 2000°C,and the refractory under load is a above 1550°C.Good steady volume in high temperature , the performance of meeting sudden cold and sudden hot is better than magnesia bricks
Specifications:
Direct-Bonded Magnesia-Chrome Brick
Main Application:It’s mainly applied to line the sintering zone of the new dry-processing of cement kilns and glass tank furnaces as checkers and the other industrial furnaces.

- Q: Process for producing magnesia chrome brick
- The fine powder compacts after calcination produced by magnesia - chrome ore grinding method, brick with magnesia coarse particles, are effective measures to eliminate the effect of loose. Compared with the common magnesia chrome brick, the magnesia chrome brick made by this method has lower porosity, higher compressive strength, higher softening temperature and higher flexural strength. Compacts with chrome magnesite powder, magnesia chrome brick by synthetic magnesia chrome sand made of high-temperature calcination, slag resistance and high temperature strength are better than other magnesite chrome brick.In addition, magnesite brick and electric arc furnace melting magnesium chromium material by direct casting (see Figure microstructure, color), fused magnesia chrome brick material produced by the process of melting particles combined with magnesia chrome brick etc..

- Q: What are the types of magnesia chrome bricks for industrial use?
- 1. burned magnesia chrome bricks 2. magnesia chrome bricks 3. semi bonded magnesia chrome brick and magnesia chrome brick generally is the three
- Q: What is a half combination of magnesia chrome bricks?
- Direct binding for magnesium magnesium rock stone or periclase spinel crystals, silicate phases were isolated in the grain asked. Half combined with thermal shock resistance than magnesia chrome brick direct bonded magnesia chrome brick, and about half combined with the characteristics of magnesia chrome brick, some physical and chemical indicators. I don't understand, I know there is a production of magnesia chrome brick factory technicians understand this, is known as gold refractory material factory.
- Q: With different capacitance magnesia brick brick
- Hello, the magnesium chromium brick into common magnesia chrome brick, magnesia chrome bricks, half magnesia chrome brick, magnesia chrome brick, semi fused magnesia chrome brick, unburned magnesia chrome brick, magnesia chrome brick and magnesia chrome brick and directly combined with the distinction lies in 1: containing magnesia (raw material) the purity of 2: the sintering temperature of common magnesia chrome brick sintering temperature at 1550 DEG ~1600 DEG, direct the magnesium chromium brick sintering temperature is over 1700 DEG C, because of its more than 1700 DEG C, magnesia chrome brick, microstructure change and periclase chromium ore directly combined, so called direct bonded magnesia chrome brick. The performance of direct bonding magnesia chrome brick is better than that of common magnesia chrome brick
- Q: What is the difference between magnesia chrome brick and direct bonded magnesia chrome brick?
- The magnesia chrome bricks are divided into ordinary magnesia chrome bricks, direct bonding magnesia chrome bricks, half bonded magnesia chromite bricks, fused magnesia chrome bricks, fused magnesia semi bonded magnesia bricks, and unburned magnesia chrome bricks
