On-line measuring device for length of bar steel to be finished

Abstract

The invention provides an on-line measuring device for length of bar steel to be finished. The on-line measuring device comprises a storage rack, a first distance measuring sensor and a second distance measuring sensor; the storage rack is provided with a positioning groove for adjusting the length direction of the bar steel; the first distance measuring sensor and the second distance measuring sensor are oppositely arranged at the two ends of the positioning groove, and the first distance measuring sensor, the first end of the strip steel in the positioning groove, the second distance measuring sensor and the second end of the strip steel in the positioning groove are located on the same straight line. The first distance measuring sensor is used for measuring the distance to the first end of the bar steel, and the second distance measuring sensor is used for measuring the distance to the second end of the bar steel; the first distance measuring sensor and the second distance measuring sensor are both connected to a controller, and a man-machine interaction device is arranged on the controller; the length direction of the bar steep is adjusted through the positioning groove in the storage rack of a shot blasting machine and / or a sharpening machine, the distance between the distance measuring sensors and the corresponding ends of the bar steel is obtained in cooperation with the two distance measuring sensors, the length of the bar steel is obtained, the measuring cost is low, and the measuring result is rapid and accurate.

Description

technical field [0001] The invention belongs to the technical field of length measurement, and in particular relates to an on-line measuring device for the length of a steel bar to be finished in a finishing area. Background technique [0002] Bar steel, that is, bar billet, including continuous casting billet and blooming billet, is mainly used to produce bars, wire rods, plates, etc. The production process is as follows: first use shot blasting machine and / or grinding machine to finish the surface defects of the bar steel, and then send the finished bar steel to different sub-factories for rolling according to the length. Get rods, wires, plates and more. Before rolling, the bar steel must be heated in the heating furnace in the corresponding sub-factory. Since the size of the hearth of the heating furnace and the pad iron of the trolley in the heating furnace in each sub-factory are fixed, only the The steel bar within the corresponding length range shall be heated. If ...

AI Technical Summary

Problems solved by technology

In order to send strips with appropriate lengths to the corresponding sub-factory for rolling; the general method of measuring the length of strips is to measure manually with a tape measure, but there are a large number of strips to be measured (about 16,000 pieces / month), It greatly increases the labor intensity of the staff, and it is very easy to make mistakes during manual measurement, resulting in too long or too short steel bars flowing into the next branch factory, causing unnecessary losses
