AI Technical Summary

Technical Problem

Existing passivation devices suffer from uneven distribution of passivation liquid during steel cooling, resulting in variations in passivation film thickness, which affects appearance consistency and corrosion resistance. Furthermore, they have low processing efficiency, with the problem being particularly pronounced in tubular workpieces.

Method used

A steel cooling and passivation device was designed, which uses a lifting component and a vibration motor. Multiple steel materials are suspended by a hanging frame component. The motor drives the horizontal plate to rotate and vibrate alternately, so as to achieve rapid and uniform dripping of passivation liquid and improve processing efficiency.

Benefits of technology

This method enables rapid and uniform dripping of the passivation solution, shortens waiting time, improves processing efficiency, ensures the uniformity and corrosion resistance of the passivation film, and enhances the service life of the material.
