What's the use of waste magnesia-carbon bricks?

1. A recycling method of waste magnesia-carbon bricks, which is characterized by comprising the following process steps: a, sorting: sorting the recycled waste magnesia-carbon bricks to remove impurities such as residue and dirt, and sorting out bricks such as aluminum, magnesium, carbon, chromium, aluminum and silicon carbide; B, homogenizing and crushing: evenly mixing the selected waste magnesia-carbon bricks, and then crushing into particles of 8-20mm to obtain unfired granular materials; C, decarbonization: putting a small amount of granular materials obtained in the second step into a combustion pool for ignition, then gradually adding the granular materials when the fire is strong, and adding the granular materials while burning until the pool is full, and keeping the temperature in the combustion pool at 1350℃- 1450℃ for 8 hours-12 hours; D, secondary crushing and screening: naturally cooling the carbon-removed granular materials, then crushing the granular materials to particles below 8mm again, and uniformly mixing to obtain the basic raw materials of the refractory materials for the ladle.
