A weighing device, conveying device and method for steel rolling production

Abstract

The invention relates to a weight measuring device for steel rolling production and a conveying device and method. A length measuring device, an outline scanner and a control system are included. Theoutline scanner is arranged in the middle of a roller way conveying line and can allow a to-be-measured part to get through and scan the section shape of the to-be-measured part. The length measuringdevice comprises a metal detector arranged on one side of the roller way conveying line. The metal detector can detect whether the to-be-measured part reaches a detection position of the metal detector. The length measuring device further comprises a coded disc coaxial with an output shaft of a driving motor. The coded disc can detect the rotation angle of the output shaft of the driving motor. According to the weight measuring device for steel rolling production and the conveying device and method, the arrangement of a conveying roller way equal to the to-be-measured part in length and a weight measuring element can be avoided, the staying time of the to-be-measured part on the roller way is reduced, the influence on rolling quality is avoided, and the weight of the to-be-measured part with a large length numerical value can be measured.

Description

technical field [0001] The invention belongs to the technical field of weighing devices, and in particular relates to a weighing device, a conveying device and a method for steel rolling production. Background technique [0002] In steel rolling production, the finished product rate has always been a key indicator for each production plant to measure and improve economic benefits. However, due to the limitation of the weighing method, generally only the weight measurement of the blank and the finished product is carried out. Billet weighing generally chooses to set a section of roller table suitable for the length of the billet in front of the heating furnace, and set weighing elements at the roller table for weighing. [0003] With the development of bar, wire rod and section steel production technology, direct rolling and endless rolling have begun to be applied to actual production, which has improved the yield of rolling line and become the process adopted by new produc...

Problems solved by technology

[0004] The inventor believes that between each rolling process, especially the continuous rolling production line, due to the large value of the length of the rolled piece, if a weighing element is to be installed, a conveying roller table with the same length as the piece to be measured must be installed, which will make the production line occupy a large area. The area has increased dramatically, so it is difficult to weigh individually; it can only be weighed in bundles after the product is fully rolled and formed

[0005] At the same time, the method of setting the conveying roller table and weighing elements equal to the length of the workpiece will prolong the time for the billet to enter the heating furnace and affect the rolling quality
