▎ 摘  要

NOVELTY - A low carbon magnesium oxide refractory material comprises 65-70 pts. wt., preferably 65 pts. wt. fused magnesia particles, 11-15 pts. wt., preferably 15 pts. wt. fused magnesite fine powder, 6-8 pts. wt., preferably 6 pts. wt. fused magnesite micro powder, 8-12 pts. wt., preferably 12 pts. wt. micro-nano graphene, 2-3 pts. wt., preferably 2 pts. wt. flake graphite, 1.5-2.5 pts. wt., preferably 1.5 pts. wt. silicon carbide powder, 1-2 pts. wt., preferably 2 pts. wt. boron carbide powder, 0.5-1 pt. wt., preferably 0.5 pt. wt. aluminum powder, 1-2 pts. wt., preferably 1 pts. wt. aluminum-magnesium alloy powder, 2-3 pts. wt., preferably 3 pts. wt. silicon powder and 3-5 pts. wt., preferably 3 pts. wt. liquid phenolic resin. USE - Low carbon magnesium oxide refractory material. ADVANTAGE - The material introduces micro-nano graphene into the magnesium carbon refractory material by reasonable proportioning and particle size grading of each raw material component, and partially replaces the flake graphite and uniformly disperses in the refractory material. The material reduces the carbon content and thermal conductivity, and increases the strength of the material and has excellent thermal shock resistance and slag corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of the low carbon magnesium oxide refractory material.
