Description

Hot galvanizing drying device

Technical Field

The utility model belongs to the technical field of the hot-galvanize equipment, concretely relates to hot-galvanize drying device.

Background

Hot galvanizing, also called hot dip galvanizing or hot dip galvanizing, is an effective metal anticorrosion mode and is mainly used for metal structure facilities in various industries. In the process flow, the workpiece needs to be dried and preheated before the hot galvanizing procedure, so that the workpiece is prevented from being deformed due to the rapid temperature rise during dip plating, residual moisture is removed, and the zinc explosion is prevented from being generated to cause the zinc liquid explosion and splashing. At present, the following two methods are mostly adopted for drying: firstly, blow with hot-blast, this kind of mode drying efficiency is not high. Secondly, the hot plate is used for drying, but the temperature at the bottom of the drying ridge is easily overhigh, so that the plating assistant agent fails due to overhigh heating of the workpiece close to the bottom. The hot galvanizing pretreatment equipment with uniform temperature distribution is to be further researched and developed.
