Production Details
Our Magnesia Chrome Bricks are manufactured through a combination of dry pressing and high-temperature sintering. Premium-grade magnesite and chrome ore are selected to ensure optimal purity and consistency. We use advanced mixing and pressing equipment, followed by kilning at temperatures over 1700°C to achieve high density and low porosity. All bricks are subject to rigorous quality control in accordance with international refractory standards.
