Dry magnesia carbon material
The invention discloses a dry magnesia carbon material which consists of waste magnesia carbon brick particles with the particle size ranges of 0.3-1 mm and 1-3 mm, magnesia matrix, phenolic resin powder, boric acid powder and so on, wherein the weight of the waste magnesia carbon brick particles with the particle size range of 0.3-1 mm accounts for 25-35% of the total weight of the raw materials; the weight of the waste magnesia carbon brick particles with the particle size range of 1-3 mm accounts for 40-50% of the total weight of the raw materials; the weight of the magnesia matrix accounts for 13-30% of the total weight of the raw materials; the weight of the phenolic resin powder accounts for 1-4% of the total weight of the raw materials; the weight of the boric acid powder accounts for 0.5-1.5% of the total weight of the raw materials. The dry magnesia-carbon material has the advantages that remaining waste magnesia carbon bricks after steel ladle using are used to replace magnesia aggregate, so that not only can waste and old materials be reused, but also the enterprise production cost is greatly reduced; in addition, the produced continuous casting tundish working layer lining is excellent in anti-scouring and anti-erosion properties, so that the production safety is improved.
