INVESTIGATION OF EQUIPMENT OF DUAL-LEADING OUT PROCESS FOR GALVANIZED STEEL TUBES

The current situation of the equipment of the dual-leading out process for steel tube galvanization in the country is investigated and a comparison between features of the star-wheel/toothed disc type line and those of the screw type line is made, pointing out that the dual-row screw type line is better in terms of comprehensive indexes.In addition, measures for improving the magnetic roller table and after-galvanization processing equipment of the toothed disc type dual-leading out line are proposed.
