Abstract

The invention belongs to the technical field of metallurgy, and discloses a converter auxiliary lance lifting control system, comprising: a programmable controller PLC, a lifting relay, a first frequency converter, a first frequency converter running state relay, a first frequency converter fault state relay, The second frequency converter, lifting motor and limit switch; the programmable controller PLC is connected with the lifting relay, the first frequency converter running state relay, the first frequency converter fault state relay, the lifting relay respectively connected to the first frequency converter and the second frequency converter, the first frequency converter and the second frequency converter are respectively connected to the lifting motor; the first frequency converter is connected to the programmable control The device is connected; the limit switch is connected with the programmable controller PLC and the second frequency converter. The lifting control system for the sub-lance of the converter provided by the present invention can efficiently deal with the failure of lifting the gun and realize the rapid operation of lifting the gun.

Description

technical field [0001] The invention relates to the technical field of automatic control of converter equipment, in particular to a converter sublance lifting control system and method. Background technique [0002] In the steelmaking converter sub-lance system, the lifting operation is performed by controlling the lifting motor through the normal lifting frequency converter and the emergency lifting frequency converter; the normal control mode and the emergency control mode are respectively implemented. However, in actual production operations, the switching and selection of control modes largely depend on the operator. When a component failure occurs in the normal control mode and the operator does not deal with it in time, it often leads to damage to the sub-gun. Contents of the invention [0003] The invention provides a converter sub-lance lifting control system and method, which achieves the technical problems of improving the efficiency of sub-lance lifting fault h...
