Abstract
The invention provides a ladle brick and a production method thereof. The method comprises the following steps: adding black regenerated sand particles and powder, fused magnesite particles, magnesite clinker particles, a plurality of antioxidants, metal silicon powder and graphite into a blending machine in sequence, adding a resinoid bond into the mixture to be stirred evenly; press forming the mixed materials on a pressing machine; placing the formed material into an infrared dryer to be dried and maintained for 12 to 24 hours at a temperature ranging from 120 to 200 DEG C to obtain a finished product. The ladle brick and the method have the advantage in using the black regenerated sand as a main raw material to produce magnesia carbon bricks and alumina-magnesite carbon bricks, cost for producing one ton of bricks can be reduced greatly on the premise that conventional physicochemical indexes of the produced magnesia carbon bricks and alumina-magnesite carbon bricks reach required quality level, and service life is improved by 10 to 20 percent compared with similar products, so that self competitive power of enterprises can be improved, resources are saved, and benefits are provided for users in production management and field management, thus achieving mutual benefits.
