[0002] Common stretching straightening machines in continuous hot-dip galvanizing lines for strip steel have three forms: two-bending two-straightening, two-bending one-straightening, and one-bending one-straightening. Among them, the two-bending one-straightening form is the most widely used. The two-bending one-straightening stretching straightening machine (tension leveling machine) mainly consists of two groups of bending roll groups, one group of straightening roll groups, several turning rolls, a roll changing device, a roll group lifting system, etc. A wet spray system is configured inside the frame on some production lines to achieve the function of wet tension leveling. During the working process of the tension leveling machine, due to the gap between the steel coil and the roller at the discharging end, intermediate rolls are required as supports to cooperate to achieve the purpose of straightening the coil. The intermediate rolls are also called support rolls or extrusion rolls.

[0003] When the existing tension leveling roll for a tension leveling machine is in use, it is generally connected to the drive seat by screwing and fixing with screws. Since there is no guiding and limiting structure during assembly, it is difficult to accurately align the screw holes. Moreover, tools are required for disassembly and assembly, resulting in troublesome assembly work. Therefore, we propose a tension leveling roll for a tension leveling machine.
