Reductor slag-removing device

Abstract

The invention discloses a slag-off device for a reductor (a kettle or a pot). The device comprises an insulator holding section (1) obliquely arranged, an end cover (2) arranged at the bottom of the insulator holding section (1), a movable sealing opening (3) arranged at the top of the insulator holding section (1), and a slag leading pipe (4) connected with the lower part of the insulator holding section (1). Because the slag-off process of the invention is based on sealing condition, the invention can reduce the heat loss in the reductor and also reduce the energy consumption, during discharging off, only a slag-off valve is needed to open, the insulator in the heat insulation section of the reductor automatically slides into the insulator holding section of the invention, reducing slagautomatically flows out from the redactor, and then directly flows into a slag leading groove. The slag-off device for a reductor (a kettle or a pot) improves work efficiency, reduces slag-off time and also reduces heat emission, thus labor environment and labor condition of workers are significantly improved.

Description

Reducer slag guide device technical field The invention relates to a slag guide device, in particular to a slag guide device for a reducer (kettle or tank). Background technique Metal vacuum smelting requires the reduction reaction temperature to be between 1000 and 1300°C, and the internal pressure of the reduction tank to be less than 10Pa to 13Pa. If the reduction reaction is carried out by charging the reducer, a large amount of reduction slag will inevitably be discharged from the reducer after the reduction reaction is completed. In order to improve the sealing degree of the slag discharge port of the reducer and reduce the heat loss in the reducer caused by slagging, the diameter of the slag discharge port should not be too large. Due to the small diameter of the slag discharge port and the high temperature of the slag discharge port, the temperature of the slag discharge port is very high during slag discharge. The workers work at high temperature, the labor inten...

AI Technical Summary

Problems solved by technology

Due to the small diameter of the slag discharge port and the high temperature of the slag discharge port, the temperature of the slag discharge port is very high during slag discharge. The workers work at high temperature, the labor intensity is high, and the working environment is harsh, which greatly affects the slag discharge. High working efficiency, prolonging the time of slagging, causing heat loss in the reducer, and increasing production costs

Due to frequent disassembly and assembly, it will also affect the reliability of the seal of the slag outlet of the reducer
