Fully Automated Dross Skimming Robot
When aluminum reacts with oxygen and other alloys, it oxidizes and forms a new compound. This resulting compound is known as dross, and it is a type of waste material. It is located at the highest level of molten metal and can block the metal on the launders, resulting in inefficiency.
Rendering human intervention completely unnecessary for the dross elimination process, Sistem Teknik designed skimmers to work with a fully automated control system to provide operational safety while minimizing the time for the furnace door to remain open and the damage to refractory material that results from the skimming process.
The dross removal process has become easier and safer without the need for human intervention thanks to fully automated dross skimming. High-temperature resistant cameras are used to collect visual data on the dross levels inside the furnace. Thus, dross levels are estimated, probability models are extracted, and dross skimming is accomplished by utilizing a telescopic arm with a cooling mechanism.
Preheating chambers heat the aluminum material up to 150-200°C. Since the material enters the melting furnace in a heated state, the melting time is shortened.
