An online flatness quality evaluation device and method for skin pass unit

Abstract

The invention discloses an online strip shape quality assessment device and method for a temper mill and belongs to the technical field of hot rolling. The online strip shape quality assessment device for the temper mill comprises an online quality inspection platform, an observation ruler, and an operation table, wherein the online quality inspection platform is arranged at an outlet of the temper mill, the observation ruler is arranged on the online quality inspection platform, and the operation table is opposite to the online quality inspection platform. The online strip shape quality assessment device and method for the temper mill can be used for judging the status of the strip shape of flattened strip steel online in real time; measurement is carried out without a halt, the rhythm of production is not influenced, the status of the strip shape of the strip steel can be accurately judged, and operating personnel can organize regulation and control over the strip shape of the strip steel in time; thus, the strip shape quality is improved, the rhythm of production is improved, and the secondary flatting rate of the wave shape is lowered.

Description

technical field [0001] The invention relates to the technical field of hot rolling, in particular to an online flatness quality evaluation device and method for a tempering unit. Background technique [0002] The flatness of hot-rolled strips is an eternal issue that emerges and urgently needs to be solved in the production process of various hot-rolled mills. higher and higher requirements. [0003] In order to meet customer needs and improve the shape quality of products, a shape meter is installed at the exit of rolling mills such as hot rolling and cold rolling lines to perform closed-loop control on the shape of the strip. However, due to the limitation of subjective and objective conditions such as investment cost and equipment space, most hot-rolling skin pass lines are not equipped with flatness meters, which cannot guarantee the closed-loop control of flatness quality, and because the flatness magnitude is extremely small (10 -5 ), and due to the comprehensive inf...
