Industrial robots provide a safe, cost-effective alternative to manual drossing. When handled manually, drossing can be a tedious and dangerous job. Robotic drossing, on the other hand, offers some serious advantages:
Stay Safe with Robotic Drossing:
Manual dross-skimming can be very hazardous to workers. The process involves galvanizing steel is by dipping it into a bath of molten zinc. This process causes solid impurities (metal oxide), called dross, to form at the surface of the bath. Dross-skimming is the a metal oxide removal method.
The zinc bath is kept at an average of 860 degrees Fahrenheit and the area surrounding the bath can reach temperatures of 100 degrees Fahrenheit and above. There is always the danger of burns, so workers wear protective clothing. This protective gear in turn makes the job even more taxing and warm. The reaching and lifting required with manual skimming can be straining and labor-intensive.
Robotic drossing provides a safe alternative. Robots can withstand high temperatures and splashes of molten zinc. Instead of tiring and endangering workers, robots work consistently without wearying.
Robotic Drossing Conserves Material:
Because manual drossing is so dangerous and so taxing on workers, consistency can be difficult to achieve. Zinc can be unnecessarily wasted. At the same time, product can be marred when the zinc bath isn't thoroughly skimmed. When this happens, metal oxide often adheres to the steel, streaking and marring the finish.
With industrial robots handling the dross-skimming, material can be conserved and the process is consistent. The robot will always remove dross at the same rate.
