Project Description

Product Name MgO Carbon Brick for Ladle Refractories Bricks
Description Magnesia Carbon brick is resin bonded, made from dead-burned or fused magnesia and graphite under proper temperature, finished after heat treatment. Addition of anti-oxidant such as metal and carbide are often being used to improve its oxidation resistance and high temperature strength.

SH Refractories steel ladle refractory solutions are customized based on shop-specific conditions to optimize refractory performance and improve safety, refractory life and yield. We provide high-performance brick and monolithic ladle linings are designed and engineered to withstand any secondary refining, heating, rinsing, and alloying in the slag line, as well as the barrel and bottom of the ladle.
