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