Method for increasing cutting fixed length yield of casting machine

Abstract

The invention discloses a method for increasing the cutting fixed length yield of a casting machine. The method for increasing the cutting fixed length yield of the casting machine comprises the stepsthat the count of a drive roller of a sector-shaped segment serves as a basis, the data is sent to a casting flow control system and a casting machine cutter control system through communication to be subjected to data and logic processing, blank length measuring calculation is carried out, and the method serves as a cutting fixed length measuring manner. By means of the method for increasing thecutting fixed length yield of the casting machine, the cutting fixed length yield of the casting machine is increased, the steelmaking production cost is reduced, the normal production rhythm is notaffected while the cost is reduced, meanwhile, no extra requirement is mentioned for equipment precision, and good popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of metallurgical control, in particular to a method for improving the qualified rate of casting machine cutting to length. Background technique [0002] Cutting to length is an important indicator for the pass rate of slabs. Once the pass rate of cut to length is low, it will not only cause serious slab quality accidents and waste of steel materials, but also cause serious economic losses. The normal production of the continuous casting machine is adversely affected, and the cost of steelmaking production is raised due to high consumption. Therefore, how to improve the qualified rate of fixed length has become an important production indicator of the casting machine section. [0003] At present, when the casting machine cutting machine is cutting to length, there are many problems in using the measuring roller to measure the length of the slab, including thermal expansion and contraction of the measuring ro...

AI Technical Summary

Problems solved by technology

[0003] At present, when the casting machine cutting machine is cutting to length, there are many problems in using the measuring roller to measure the length of the slab, including thermal expansion and contraction of the measuring roller, poor coaxiality of the encoder, insufficient compression of the measuring roller, encoder signal Quantitative errors caused by interference, periodic wear of measuring rollers, etc., lead to inaccurate measurement of measuring rollers, low pass rate and non-cut slabs, resulting in serious slab quality accidents and economic losses

In addition, the thermal expansion and contraction of the measuring roller during production, and at the same time, once the pressing force is not enough during production, the cooling is not good, etc., which will easily lead to large errors in the measuring roller.

Moreover, due to the long-term contact between the slab and the measuring roller during production, there is wear and tear. If the bearing of the measuring roller is not well lubricated, severe friction will occur, resulting in equipment failure and increased maintenance costs.
