Air-blowing slag-removing device

Abstract

The invention relates to the technical field of molten iron pretreatment, in particular to an air-blowing slag-removing device. The air-blowing slag-removing device increases the angle adjusting effect of an air-blowing rod, increases the molten iron pretreatment effect and improves the practicability. The air-blowing slag-removing device comprises a support, a first rotating seat, an air cylinder, a second rotating seat, a rack, a third rotating seat, a fourth rotating seat, a transmission mechanism, an air blowing mechanism and a guide mechanism, the first rotating seat is fixedly installed on the support, the air cylinder is rotationally connected with the first rotating seat, a piston rod is arranged at the output end of the air cylinder, and the second rotating seat is fixedly installed on the rack. The piston rod is rotationally connected with the second rotating seat, the transmission mechanism is installed on the rack, the air blowing mechanism is installed on the transmission mechanism, the transmission mechanism drives the guide mechanism to move, the air blowing mechanism blows air into molten iron to conduct molten iron pretreatment, the guide mechanism is installed on the transmission mechanism, and the guide mechanism plays a guiding role in the moving process of the transmission mechanism. The third rotating seat is fixedly installed on the support, and the fourth rotating seat is fixedly installed on the rack.

Description

technical field [0001] The invention relates to the technical field of molten iron pretreatment, in particular to an air blowing slag removal device. Background technique [0002] Hot metal pre-desulfurization is one of the indispensable processes for optimizing the metallurgical production process. It can reduce the coke ratio of continuous steel casting|ironmaking, increase productivity, reduce the consumption of lime and slag in steelmaking, thereby reducing production costs; The angle adjustment of the blowing rod of the existing air blowing and slag removing device is manually completed, and there is danger because the temperature is too high. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an air blowing slag removal device which increases the effect of adjusting the angle of the blowing rod, increases the effect of pretreatment of molten iron, and improves the practicability. [0004] An air blowing ...
