Abstract

The invention discloses a roller convenient to disassemble and change, which comprises a roller central shaft and a roller body arranged on the roller central shaft, wherein one end of the roller body is provided with a plurality of grooves, the roller central shaft is provided with a plurality of lug bosses matched with the grooves, the roller body is externally provided with a work roller ring, the work roller ring comprises a work region and fastening regions arranged at two ends, the thicknesses of the fastening regions are less than the thickness of the work region, the fastening regions are respectively provided with a fastening bolt, the fastening bolts penetrate through the fastening regions and into the roller body, the lug bosses are respectively provided with a bolt, the bolts penetrate through the lug bosses and enter into the roller body. Due to the mode, the roller is flexible in structure, a work layer can be disassembled and changed, the production schedule can not be influenced, each part is made from different materials, and the roller is less in manufacture cost.

Description

technical field [0001] The invention relates to the technical field of rolls, in particular to a roll that is easy to replace. 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 mainly bears the dynamic and static loads, wear and temperature changes during rolling. In order to meet the needs of steel rolling production, the roll body requires a high-quality working layer with high wear resistance, peeling resistance and surface roughening resistance. Most of the existing rolls adopt an integrated structure, the structure is relatively rigid, the material is single, the manufacturing cost is high, and the repair is cumbersome. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a roll that is easy to dismantle and replace, which can solve the defects in the prior art, has a flexibl...
