... Abstract This article illustrates the basic components of dry and wet hearth reverberatory furnaces. It discusses stack melters that are used for aluminum metal casting, as they are efficient in sealing the furnace and using the flue gases to preheat the charge materials. The article describes...

... and Procedures for Small Operations A major step in scrap processing is size reduction. Large items must be cut to simplify handling, increase density, and to enable them to be charged into a furnace. For small-scale scrap processing, gas-cutting, plasma-arc, or carbon-arc torches are the tools...
