What Are the Differences in the Production Processes of Directly Bonded Magnesia-Chrome Bricks and Ordinary Magnesia-Chrome Bricks?

What Are the Differences in the Production Processes of Directly Bonded Magnesia-Chrome Bricks and Ordinary Magnesia-Chrome Bricks?

Our Blog
The main difference between the production processes of directly bonded magnesia-chrome bricks and ordinary magnesia-chrome bricks lies in the former's use of raw materials with lower impurity content and higher firing temperatures. The raw materials used to produce directly bonded magnesia-chrome bricks typically have an MgO content greater than 95% and a Rongsheng refractory material content greater than 97%. The particle bulk density is around 3.25 g/cm3, and the SiO2 content in the gangue is generally limited to below 3%.…

How Much Does High-temperature Refractory Brick Cost Per Ton?

Our Blog
High-temperature refractory brick refers to a type of refractory material that can withstand high temperatures without being damaged. It is commonly known as firebrick and is widely used as the lining material in high-temperature industrial kilns and furnaces. High-temperature refractory bricks are made by mixing refractory raw materials into a clayey mixture, filling the mixture into molds, and then high-pressure molding with a friction brick press. After drying and removing a portion of the free water, the bricks are fired…

Expansion of Corundum Mullite Bricks in the Refractory Industry

Expansion of Corundum Mullite Bricks in the Refractory Industry

Our Blog
Corundum mullite bricks, known for their exceptional properties and composition of corundum and mullite, are widely recognized as high-alumina refractory bricks. These bricks are fabricated from high-purity or relatively pure raw materials, ensuring their remarkable heat resistance and durability. However, it is crucial to address the impact of low-melting-point oxide impurities on their high-temperature performance. Notably, corundum mullite bricks are more expensive compared to ordinary high-alumina bricks due to their superior physical and chemical characteristics. The distinguishing features of corundum…
