Though the ceramic rollers for galvanizing bath has better performance, most companies in the steel wire galvanizing industry use low carbon steel rollers (05F~08F) for galvanizing bath. As important parts for galvanizing line, when the low carbon steel rollers stay in the high temperature melted zinc for a long time, they will get seriously corroded. Accordingly, the galvanizing performance will also decrese.
The service life of a typical low carbon roller is about 3-5 years, and frequent production halts are needed for maintenance. So we decided to develop better rollers for galvanizing. The silicon nitride and silicon carbide are adopted to improve the anti-corrosion performance and service life. By rigid calculation and dynamic simulation designing, our ceramic rollers for galvanizing bath comes in a curved circular sector shape, meeting all the requirements of vertical wire lifting technique and inclined wire lifting technique for bending radius. The advancing resistance to the steel wire is also reduced. The trough design on the circular sector surface can guarantee the the stability during the wire moving.
