Roll body hardness analysis method for roller

Abstract

The invention relates to a roll body hardness analysis method for a roller, and belongs to the technical field of roller hardness detection. The roll body hardness analysis method for the roller comprises the following analysis steps: uniformly drawing up a plurality of generatrices around the roll body circumference of the roller, wherein the roll body circumference of the roller is averagely divided into a plurality of areas according to the total length of the roll body of the roller; detecting the hardness values of all the generatrices in each area and recording the hardness values; usingthe recorded hardness values of the generatrices to calculate the average hardness value of the generatrices of the roll body of the roller, the average hardness value of the area and the average hardness value of the whole body; and analyzing the overall hardness level of the roll body of the roller and judging whether the roll body is of male and female faces according to the average hardness values of the areas and the average hardness value of the generatrices. According to the method, the overall hardness level of the roll body of the roller, the hardness distribution type and whether the roll body is of male and female faces can be analyzed, so that the basis is provided for the improvement of manufacturing technique.

Description

technical field [0001] The invention relates to a method for analyzing the hardness of a roll body, belonging to the technical field of rolling roll hardness detection. Background technique [0002] The roll is an important part of the rolling mill in the rolling mill. It uses the pressure generated by a pair or a group of rolls to roll the steel. It is subjected to strong rolling force, severe wear and high temperature conditions during work, which affects the roll body. There are high requirements for hardness and tolerance, and only when a certain hardness requirement is met can it be put into the production process. Therefore, an accurate roll body hardness testing method is very necessary. [0003] At present, the hardness test of the roll body is generally carried out according to the roll Shore and Leeb hardness test methods. The test results only use the maximum and minimum values ​​to compare with the technical conditions, and then judge whether the roll hardness i...
