The step-by-step debugging method of the electrical system of the ladle turntable of the continuous caster

Abstract

The invention discloses a step-by-step debugging method of a ladle turret electric system of a continuous casting machine. The method is characterized by comprising the following steps: an electric circuit is checked before electrification; in a decoupling state, joint test and position detecting switches of all input / output points of related substations of a ladle turret are primarily positioned; lifting / descending functions of a ladle cantilever are tested; lifting / descending and shifting-in / shifting-out functions of a ladle capping device are tested; a rotating function of a rotary table is tested; a driving motor monomer of the rotary table is in trail operation; the driving motor of the rotary table drives machinery to perform trail operation; and the 0 position of a motor position encoder is determined. The debugging method finishes the checking work of the electric circuit before electrification of all substations of a PLC, finishes input and output interface tests of all the substations in the decoupling state, and finishes most electric system debugging operations before feeding of a ladle hydraulic and lubricating system, so that the electric system debugging operation safety risk is greatly reduced when the debugging quality is guaranteed and the debugging period is shortened.

Description

technical field [0001] The invention relates to the field of installation and maintenance of electrical systems of large equipment, in particular to a step-by-step debugging method for the electrical system of a ladle rotary table of a continuous casting machine. Background technique [0002] The ladle turret is the key equipment for the continuous casting machine to undertake ladle spanning and realize multi-furnace continuous casting. Whether its electrical system can be put into operation early and run normally is directly related to the construction progress and quality of the entire continuous casting production line. At present, the commonly used debugging method is that the electrical system debugging is carried out along with the construction progress of electrical and mechanical equipment installation and hydraulic pressure and lubrication. After the PLC substation is powered on, there are still many wiring and line inspections. There are problems in the normal opera...

Problems solved by technology

At present, the commonly used debugging method is that the electrical system debugging is carried out along with the construction progress of electrical and mechanical equipment installation and hydraulic pressure and lubrication. After the PLC substation is powered on, there are still many wiring and line inspections. There are problems in the normal operation of the PLC system and personal safety. There are hidden dangers; at the same time, the commissioning of the ladle cantilever, the ladle capping device, and the internal electrical substation of the ladle turret involves a lot of high-altitude operations.
