Problems solved by technology

When the ladle is turned over, because the superheat of the molten steel is very small, it must be turned over quickly, and all the casting slag must be poured out within 1-2 minutes, otherwise it will condense due to the temperature drop of the molten steel, espe

Abstract

The invention discloses a hot casting slag treatment system. The hot casting slag treatment system comprises a heating device and further comprises a tundish, a roller device and a conveyor which arearranged in sequence. The tundish is used for receiving casting slag in steel ladles and can pour the casting slag into the roller device. The heating device is used for heating the casting slag in the tundish. The roller device is used for treating the casting slag into slag particles. The roller device is provided with a discharge chute. The slag particles slide onto the conveyor through the discharge chute. The conveyor is used for conveying the slag particles. The hot casting slag treatment system provided by the invention can make slag poured out from the steel ladles quickly, protect thesteel ladles against weight increase, enables feeding of the roller device to be controllable, effectively reduces the phenomenon that molten steel in a roller is solidified into a large cold steel block and achieves online treatment on hot casting slag.

Description

technical field [0001] The invention relates to the technical field of metallurgical slag treatment, in particular to a hot casting residue treatment system. Background technique [0002] Casting slag refers to the general term for steel slag (slag) and residual molten steel in the ladle after steel casting, also known as ladle slag. Generally speaking, 1-3 tons of molten steel or more will remain in the ladle at the end of steel casting, and the temperatures of steel slag and molten steel are around 1500°C and 1550°C respectively. Cast steel has realized continuous casting, but the generation of casting slag is intermittent, and a bag of casting slag is about half an hour. Except for a few steel mills that directly return a small amount of casting slag to the production process for thermal recycling, most of the casting slag needs to be cooled. Due to the high metal content in the casting slag, the solidification point of the residual molten steel is relatively high, and ...
