Liquid casting residue treatment process

The invention discloses a liquid casting residue treatment process, and belongs to the technical field of metallurgical residue treatment. The method comprises the following steps: adding an improver into molten liquid casting residues, carrying out heat preservation treatment, carrying out oxygen blowing standing treatment, carrying out air quenching quenching treatment on the liquid casting residues by adopting high-speed airflow, atomizing the liquid casting residues into small liquid drops, and naturally cooling in the air to form atomized steel slag balls. According to the air quenching process for the liquid casting residues, the liquid casting residues are rapidly treated through high-speed airflow, the air quenching process has the advantages of being short in flow, short in time and low in cost, the finished product can be obtained after preliminary screening, and the whole air quenching utilization rate is high. The method is not only suitable for high-temperature liquid casting residues which are j
