Foundry Slag Skimmer for Steel, Iron and Other Molten Metals


Foundry requires a device to assist operators in removing slag from a scrap melt furnace. The process involves skimming the slag, removing it through a door and dumping into a bucket as well as manipulating the scrap in the furnace to complete the melt process. These operations were done manually with the operator standing next to the open furnace door utilizing a long handle ladle. The same process typically applies to melting steel, iron, copper, aluminum scrap and other metals.


A mechanical skimming manipulator device was provided suspended from an articulating arm assembly. The device can be used to skim the slag and deposit it outside the furnace; the device also has rake-like tines providing the operator mechanical advantage while manipulating the scrap inside the furnace. The articulating arm supports the weight of the skimmer as well as providing a fulcrum for the device, offering the operator mechanical advantage while maneuvering the scrap inside the furnace. The length of the device allows the operator to stand away from the door of the furnace, keeping him in a safer position from the heat, fumes and splattering of the molten metal.
