Abstract

The invention relates to the technical field of metallurgy, and particularly discloses a casting residual slag recovery and charging system. The casting residual slag recovery and charging system comprises a frame, and further comprises a primary fixed grid for receiving and filtering casting residual slag, a secondary movable grid for receiving and filtering the casting residual slag from the primary fixed grid, a slag collecting bin for receiving the casting residual slag from the secondary movable grid, a valve connected to a vertical pipe at the bottom outlet end of the slag collecting binand used for the on-off state of the vertical pipe, a movable feeder installed at the bottom output end of the vertical pipe and with a telescopic discharging port and a charging assembly arranged below the movable feeder and used for receiving materials from the movable feeder which are correspondingly and sequentially arranged on the inner side of the frame, and under the extension of the bottom discharging end of the movable feeder, the movable feeder can be inserted into a charging cavity of the charging assembly. According to the casting residual slag recovery and charging system, the difficult problem of recovery of the casting residual slag is effectively solved, and meanwhile the energy conservation and emission reduction and benefit improvement of enterprises can further be promoted.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a system for recovering and charging excess powder slag. Background technique [0002] The remaining top slag poured into the ladle after refining in the steelmaking process is equivalent to a kind of refining slag premixed in the steelmaking process. It has high alkalinity, good metallurgical properties, reasonable composition, and fast slag melting. Except for some furnaces with high S content, the S in the slag of most furnaces is not saturated, and it can be reused in the refining process for the second or even third use to save lime, save auxiliary materials such as slag fluorite, and increase slag Quantity, promote slagging, improve submerged arc, protect ladle refractory, save power consumption and shorten refining cycle, so as to promote the cost reduction and efficiency increase of enterprises. [0003] At present, many iron and steel enterprises equipped with refini...
