Abstract

The invention discloses a method and system for separating manganese-silicon casting iron scraps. The method for separating manganese-silicon casting iron scraps comprises the following steps of: putting discharged molten iron into a steel ladle; performing forced air cooling on the surface of the molten iron in the steel ladle to form incrustation on the surface of the molten iron; forming an iron discharging hole on the incrustation to pour the molten iron in the steel ladle into a buffering filtering package; and pouring the molten iron in the buffering filtering package into an iron basin. Due to the adoption of the method for separating manganese-silicon casting iron scraps in the embodiment of the invention, the iron scrap separating effect is greatly improved, the yield is increased, and the sizing workload of operating personnel is lowered.

Description

technical field [0001] The invention relates to the field of manganese-ferroalloy manufacturing, in particular to an improved manganese-silicon casting slag-iron separation method and separation system. Background technique [0002] In the existing manganese silicon casting process, the specific casting process is as follows: [0003] Slag dumping→slag removal→coarse filtration. [0004] In addition, in the existing manganese-silicon pouring process, the method of natural cooling and pouring and filtering is adopted, and the separation effect of slag and iron is not ideal. Specifically, there are the following problems. [0005] First of all, during the furnace tapping process, due to the difference in specific gravity between the slag and the molten iron, the molten iron sinks to the bottom, while the slag floats on the surface of the molten iron. Under the premise of natural cooling, after the slag pouring and slag removal processes, a part of the slag will still remain...
