High-temperature-resistant and corrosion-resistant stable roller

Abstract

The invention discloses a high-temperature-resistant and corrosion-resistant stable roller, which comprises a roller and a roller shaft connected to both ends of the roller; the end connected to the roller shaft and the roller is a radial plate structure in which more than three radial plates are evenly distributed on the circumference; There is an external thread on the outer circumference of the spoke plate, which is threadedly connected with the internal threaded hole at the end of the roller; more than one anti-loosening screw is provided at the thread connection between the internal threaded hole at the end of the roller and the threaded plate of the roller shaft; further improvement lies in: anti-loosening screw The number is the same as the number of roller shaft webs, and they are evenly distributed in the circumferential direction of the inner threaded hole wall at the end of the roller; the end of the roller shaft away from the roller is provided with a center hole, and plugging is installed in the center hole; the webs of the roller shafts at both ends are in the The central axis of the rollers is staggered in the circumferential direction; the outer wall of the roller is covered with a cobalt-based alloy roller sleeve. The invention effectively prevents the loose connection of the roller and the roller shaft, and at the same time, the assembly or disassembly of the roller and the roller shaft is convenient and fast, and is corrosion-resistant, heat-resistant and high-temperature-resistant.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing, in particular to a stabilizing roll on a hot-dip galvanizing device. Background technique [0002] The stabilizing roll on the existing hot-dip galvanizing device generally includes a roller and a roller shaft connected to both ends of the roller. The roller shaft is inserted into the inner hole at the end of the roller and fixedly connected. It takes time and trouble to assemble or disassemble the shaft; second, the cross-sectional area of ​​the zinc liquid passing through is small, and the zinc liquid cannot pass through the cavity of the roller smoothly; third, after measures are taken to prevent the connection of the roller and the roller shaft from loosening But it takes time and trouble to assemble or disassemble the roller and roller shaft. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art, and provides a method that can signi...
