During real hot galvanizing production, surplus molten zinc and zinc accretions on the workpiece from molten zinc are unavoidable because of different shapes. Influencing the appearance quality of the galvanized workpiece as well as increasing the zinc consumption notably, they raise the after-galvanizing treatment work amount. In order to solve this difficult problem, our company organized technical personnel to cooperate with some galvanizing factories, and has developed “special vibrator for hot galvanizing”. Long-term operation and experiment indicate that the vibrator has stable work property, excellent accretion-eliminating results and low repair rate. It is warmly welcomed and well received by hot galvanizing factories.
Using method:
1、Hang the lifting ring of the vibrator on the hook of traveling crane; hang slings on the hook of the vibrator;
2、Insert the fixed end of the steel-wire rope of the crane hook into the spiral cable of the vibrator from the top to the bottom, fix the end and the top end of the cable on a proper location of the motor hoist, connect electric source with the cable using rubber cable and control switch is set on its outside. Weld a support plate on the shell of the hook pulley to move the spiral cable. (See photo)
3、Adjust the top lifting limit of the hook to proper location.
4、After the workpiece is completely immersed into molten zinc, switch on the vibrator and make it oscillate. Owing to high oscillating frequency and proper amplitude, vibrating force can be transferred to the workpiece through steel-wire rope, keep it high frequency vibration in molten zinc, and so “ash and slag” are floated rapidly, galvanizing time is decreased and coating becomes thinner. After “ash and slag” is completely floated, switch off vibrator and use skimming knife to eliminate floated “ash and slag”. Finally the crane lifts the workpiece from molten zinc at 1.2~1.5 m / min speed. 
5、After the whole workpiece leaves molten zinc surface, switch on the vibrator and so the surplus zinc accretions on it fall into the zinc pot.
