Magnesia Chrome Brick with Different Manufacturing Process
Common Magnesia Chrome Bricks
This product uses ordinary chrome ore and magnesia. The sintering temperature is about 1550℃. The other name is silicate bonded magnesia chrome brick because its chrome ore contains SiO2 and CaO. Compared with ordinary magnesia brick, the overall performance is improved.
Direct Bonded Magnesia Chrome Bricks
The raw materials of this magnesite chrome refractory bricks for sale are chromium concentrate with low impurity content and high-purity magnesia. Besides, the sintering temperature is about 1700°C. Its structural feature is that the product grains are mostly in direct contact.
Rebonded Chrome Magnesite Bricks
Recombination means that magnesia and chromium raw materials are processed by electrofusion and then used as raw materials to make fused magnesia chrome bricks. The rebounded magnesia chrome brick have higher purity. Therefore, the overall performance has improvements in many aspects.
Sintered Magnesium Chromium Bricks
Sintered magnesia bricks are made from top-notch sintered magnesia sand and binders. First, these materials are mixed and pressed together under high pressure. Then, it comes to the sintering process in a tunnel kiln at temperatures over 1550℃. Overall, the siontering process results in a dense structure. Here are more information on Kerui YouTube.
