Partitioned step-by-step debugging method for electrical systems of fan-shaped sections of slab continuous-casting machine

Abstract

The invention relates to a partitioned step-by-step debugging method for electrical systems of fan-shaped sections of a slab continuous-casting machine. The partitioned step-by-step debugging method comprises the following steps: step 1, carrying out offline inspection on the fan-shaped section in a maintenance area; step 2, carrying out online decoupling testing on the fan-shaped section in a casting flow area; step 3, carrying out online action testing on the fan-shaped section in the casting flow area; and repeating steps 1 to 3 so as to complete the debugging of the electrical systems of other fan-shaped sections. The reasonable partitioning is achieved according to the composition and characteristics of the slab continuous-casting machine; the debugging operation is divided by areas into an offline maintenance operation area and an online casting flow operation area; meanwhile, the procedure, the main content and the mode of the debugging of the electrical systems of the fan-shaped sections of the slab continuous-casting machine are scientifically and reasonably arranged; therefore, the safety risk of the debugging operation on the electrical systems is reduced while the debugging quality is ensured and the debugging period is shortened; the partitioned step-by-step debugging method is convenient to organize and implement; in the debugging process of the electrical systems of all the fan-shaped sections, the execution can be organized in a line-production manner; and the execution on several fan-shaped sections can be organized in a parallel-operation manner according to site conditions.

Description

technical field [0001] The invention relates to the field of large-scale equipment installation and debugging, in particular to a divisional and step-by-step debugging method for an electrical system of a slab continuous casting machine segment. Background technique [0002] The sector section is the key equipment of the slab continuous casting machine. In addition to guiding and conveying the dummy bar, it is also used for supporting, cooling, pulling out and straightening the slab, and preventing the slab from bulging under the hydrostatic pressure. The belly is deformed. Whether the electrical system of each sector of the slab continuous casting machine can be put into operation early and run normally is directly related to the construction progress of the entire continuous casting production line and the quality of the final slab. After the production line is put into operation, in addition to the normal online work, each segment body also needs to carry out offline mai...

Problems solved by technology

The commissioning of the electrical system is greatly affected by the construction progress of on-site electrical, mechanical equipment installation and hydraulic pressure, and there are hidden dangers in the normal operation of the PLC system and personal safety; A large number of high-altitude operations; after the hydraulic system in the casting area is put into operation, the online operation environment of the sector body becomes poor, which makes the above operations have many potential safety hazards
