Embodiment Construction

[0021] Specific embodiments of the present invention will be described in detail below. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0022] The present invention provides a method of measuring the distance between rolls in a rolling mill, the method comprising:

[0023] (1) Prepare the pre-rolled sample 5, heat the pre-rolled sample 5, and then turn on the rolling mill, so that the heated pre-rolled sample 5 is rolled by the upper roll 1 and the lower roll 4 to obtain a rolled sample;

[0024] (2) Use the caliper 3 to measure the thickness of the rolled sample to obtain the distance between the upper roll 1 and the lower roll 4 . By using the method of pressing small samples before driving through the steel, the steel material during rolling can be simulated, and the size of the small steel sample can be accurately measured, so as to ef...

Abstract

The invention discloses a method for measuring the distance between rollers in a rolling mill. The method comprises the steps of preparing a pre-rolling sample, heating the pre-rolling sample, then starting the rolling mill, and rolling the heated pre-rolling sample through the upper roller and the lower roller to obtain a rolled sample; and measuring the rolled sample through a pair of calipers to obtain the distance between the upper roller and the lower roller. By means of the method, the problem that if the rolling mill adopted has a certain amount of bounce, a traditional measurement method has large errors when used for measuring the distance between the rollers, and consequently the steel stacking accident is easily caused in the subsequent steel feeding process is solved.

Description

technical field [0001] The invention relates to the field of steel rolling production, in particular to a method for measuring the distance between rolls in a rolling mill. Background technique [0002] In steel rolling production, often when changing rolls and slots, steel stacking accidents are caused due to uncertainty about the bounce of the rolling mill used and the steel material passing through the steel. The current method of measuring the distance between the rolls in the rolling mill is: use a caliper to measure the rolling groove between the upper roll and the lower roll before passing the steel, and then use a caliper to measure the size of the opening of the caliper. The disadvantage of this method is: if the rolling mill has good performance , there is no bouncing, so the measured size is relatively accurate; if there is a certain amount of bouncing in the rolling mill used, resulting in a large error in the measured value, then it is impossible to accurately j...
