Embodiment 1
[0036] A steelmaking refractory recycling process, the steps comprising:
[0037] (1) Dust removal: Collect the discarded steel-making refractories and wash them with water to remove the dust on the surface of the discarded steel-making refractories;
[0038] (2) Remove slag layer and permeable layer: use manual knocking method and tangential method to remove slag layer and permeable layer of discarded steelmaking refractory materials;
[0039] (3) Crushing processing:
[0040] aCoarse crushing: use jaw crusher to roughly crush the waste steelmaking refractory materials that have removed the slag layer and the permeable layer;
[0041] b Fine crushing: the waste steelmaking refractory materials after coarse crushing are finely crushed with a hammer crusher;
[0042] (4) Powder sieve: sieve the finely crushed waste steelmaking refractory particles into three specifications, namely 2-7mm, 0.5-2mm, and 0-0.5mm;
[0043] (5) Roasting: According to the three specifications of th...
