Automatic number marking device for continuous casting blanks

Abstract

The invention discloses an automatic number marking device for continuous casting blanks. The automatic number marking device comprises a pneumatic actuator, a hot metal detector, a manipulator proximity switch and a strand PLC control system, wherein the pneumatic actuator is installed on a conveying roller way tail end baffle corresponding to a strand and can mark the casting blanks with corresponding strand numbers, the hot metal detector is arranged above the pneumatic actuator and can detect whether the casting blanks reach the upper part of a manipulator, the manipulator proximity switch is arranged below the pneumatic actuator and can detect whether the manipulator tilts completely, and the strand PLC control system is electrically connected to the pneumatic actuator, the hot metal detector and the manipulator proximity switch. The automatic number marking device has the advantages that the reject selection range of the casting blanks is greatly narrowed by automatically marking the casting blanks with the corresponding strand numbers, and the positive effect on improving the product quality, increasing the yield of the casting blanks and lowering the labor intensity of workers is realized.

Description

technical field [0001] The invention relates to the technical field of continuous casting equipment, in particular to an automatic marking device for continuous casting slabs. Background technique [0002] Most of the continuous casting machines currently in use use multi-strand continuous casting, that is, casting more than two strands of slabs simultaneously on one continuous casting machine. In the continuous casting production process, the slabs produced by each strand pass through the conveying roller table to the end baffle device of the conveying roller table, and then the steel turning machine turns over each slab staying on the end baffle device of the conveying roller table. Send it to the chain hoist, and then enter the next production process from the chain hoist to achieve the purpose of continuous production. During the pouring process of continuous casting molten steel, due to reasons such as liquid level fluctuations, non-rotating roller tables, and abnormal...

AI Technical Summary

Problems solved by technology

When there is a quality problem in the slab of a certain strand, in order to ensure the quality of the product supply, it is necessary to screen out the problem slab. Since the slabs of each strand are mixed together, the operator needs to check the slabs of all the strands one by one. Only after the selection can the problem casting slabs be screened out, not only the labor intensity of the workers is high, but also the problem casting strand cannot be determined in time
