▎ 摘  要

NOVELTY - Steel ladle casting material comprises 75-82 pts. wt. white corundum or plate corundum, 8-12 pts. wt. alpha -active aluminum oxide micro-powder, 3-7 pts. wt. magnesium sand powder, 3-6 pts. wt. pure calcium aluminate cement, 0.20-0.30 pts. wt. additive, 0.05-0.1 pts. wt. graphene, where graphene is introduced into the material in the form of slurry, where the slurry with water as solvent, the graphene in the slurry is 3-5 pts. wt., 93-95 pts. wt. water, 1-2 pts. wt. dispersing agent and the viscosity of the slurry is less than or equal to 2500mpa s. USE - Used as steel ladle casting material. ADVANTAGE - The material improves the anti-erosion of the refractory material properties and thermal stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing steel ladle casting material comprising taking all the raw materials, stirring uniformly and then packaging, on-site stirring, adding graphite alkene aqueous slurry, fully stirring and mixing uniformly, casting and molding.
