Castables for trough cover/High strength, excellent thermal shock resistance and spalling resistance
Product description:
The castables are developed by Xinyu Refractory according to the service condition of iron and slag trough cover,and are characterized with high strength, excellent thermal shock resistance and spalling resistance. They are widely applied as the cover for large blast furnace iron trough, slag through,and play the roles of insulation,preventing hot metal and slag from splashing.
