Automatic calling method for roller hearth furnace steel plate quenching process

Abstract

The invention discloses an automatic calling method for a roller hearth furnace steel plate quenching process, relates to the technical field of steel production, and comprises the following steps of debugging a quenching plate shape, recording a debugging and stabilizing process, and calling for production; inputting the debugging and stabilizing process into a secondary system, wherein the input specification is that the interval of the water temperature is set from 0 DEG C to 35 DEG C according to the interval of 5 DEG C, and the interval of the steel plate width is set from 1000 mm to 3250 mm according to the interval of 500 mm; and searching from the secondary system according to a quenching calling rule, executing when the secondary system has a conforming process, and inputting after manual debugging if the secondary system does not have a matching process. The problem that the quenching plate shape is unstable due to changes of water temperature and steel plate specifications is effectively solved, quenching processes with different water temperatures, steel types and specifications are refined, quenching water consumption is reduced, manual calling errors are reduced, and the qualified rate of the quenching plate shape is increased.

Description

technical field [0001] The invention relates to the technical field of iron and steel production, in particular to a method for automatically invoking the quenching process of steel plates in a roller hearth furnace. Background technique [0002] The process call is manually called during the quenching production of the steel plate in the medium and heavy plate coil factory. The process setting mainly takes the water temperature below 25°C and above 25°C as the dividing point. The debugging and tracking process is time-consuming and laborious, and the consumption of quenching water is relatively large. Contents of the invention [0003] The present invention aims at the above technical problems, overcomes the shortcomings of the prior art, and provides a method for automatically invoking the quenching process of steel plates in roller hearth furnaces, including [0004] Debug the quenched plate shape, record the debugging and stable process and call for production; [00...

AI Technical Summary

Problems solved by technology

[0002] The medium and heavy plate coil factory calls for manual process during quenching production of steel plate. The process setting mainly takes the water temperature below 25°C and above 25°C as the dividing point. The shape of the steel plate is very unstable when the water temperature, width, thickness, etc. change. The debugging and tracking process is time-consuming and laborious, and the consumption of quenching water is relatively large
