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…
