Description

A hanger for batch hot-dip galvanizing

technical field

The utility model relates to a galvanized hanger, more specifically, the utility model relates to a hanger for hot-dip galvanizing, especially a hanger for batch hot-dip galvanizing of steel components.

Background technique

During batch hot-dip galvanizing, the galvanizing of workpieces is intermittent. Before galvanizing, the zinc ash on the liquid surface in the zinc pot is cleaned by hand with ash rake. The workpiece is completely immersed in the zinc bath, and the driving stops falling; at this time, the rack of the hanger is above the surface of the zinc bath, the workpiece on the hook is below the surface of the zinc bath, the upper part of the hook is exposed above the zinc bath, and the lower part of the hook is immersed Below the surface of the zinc bath. After the scheduled immersion time is reached, the vehicle drags the hanger to move forward and backward several times along the width direction of the zinc pot. In the gap between the forward and backward movements, part of the liquid surface of the zinc bath is exposed, and the worker holds the ash rake to expose the The zinc ash on the liquid surface is cleaned, and then the hanger rises under the traction of the crane, and the workpiece is moved out of the zinc bath and transferred to the next process. Adopt this traditional hanger immersion plating, because there are many hooks distributed on the surface of the zinc bath, the exposed liquid surface is discontinuous, the dusting operation is loaded down with trivial details, and the zinc dust is difficult to clean up. In addition, during batch hot-dip galvanizing production, the liquid surface of the zinc pot is an open system, and the zinc bath is in direct contact with the atmosphere. At the moment of dipping, the ammonium zinc chloride on the surface of the workpiece is heated and decomposed to produce part of the scum and a large amount of smoke. , Seriously endanger the physical and mental health of the operator.

In the practice of batch hot-dip galvanizing, there is no uniform standard or specification requirement for the hanger. It generally consists of a rack plate with two lifting lugs above the rack plate and multiple rows of hooks connected to the bottom of the rack plate. Workpieces are hung on the hooks during production operations. , this hanger is simple in structure, and cost is low, but is difficult to adapt to the requirement of mechanized ashing. Chinese patent (patent number: ZL 201020223710.8) discloses a device for cleaning impurities on the surface of the galvanized liquid surface. It consists of two sets of heat preservation devices and impurity scrapers. Together, the width of the scraper is the same as the width of the liquid surface in the zinc pot. The scraper is fixed on the heat preservation device and can rotate around a pin to 1 cm below the zinc liquid surface; when the heat preservation device is driven by the hoist along the zinc pot When the guide rails on both sides move, the scraper scrapes the zinc ash into the impurity receiving tank at the end of the zinc pot. With this patented technology, the zinc ash on the surface of the zinc bath in the zinc pot can be cleaned before immersion plating; however, the hooks distributed on the surface of the zinc bath liquid hinder the movement of the scraper during immersion plating. And with the increase of the processing volume of hot-dip galvanized workpieces in batches, the total zinc consumption continues to increase, causing the zinc bath liquid level in the zinc pot to drop. If zinc ingots are not added to the zinc pot in time, the scraper will run suspended and the Zinc dust cannot be scratched. However, due to the complexity of the size and shape of the workpiece to be plated, the limitation of the operating space, and the discontinuity of the batch hot-dip galvanizing process, since the invention of hot-dip galvanizing in 1742, the field of batch hot-dip galvanizing has remained Continue to use manual dusting. For this reason, it will be an urgent problem to be solved by technicians in the field of batch hot-dip galvanizing to study a new structure of hanger to adapt to the future mechanization or even automatic dusting operation to replace the current manual dusting operation method and improve the operating environment.
