These workers use small furnaces to melt their metal. They read temperature gauges and make adjustments to the heat in order to melt the metal at the proper temperature. They use ladles to transfer the metal to the ingot. Next, ingot headers stencil identifying marks on the ingots. When the ingots are cool, ingot headers open the molds and remove the ingots.
Casters are similar to steel pourers in that they pour metal into molds.
However, they have additional duties. Casters skim impurities off the surface of the metal once it is in the molds. They use a dross hoe, metal rake, or carbon stick for this purpose. They stamp identifying stencils on the cooled metal. Next, casters remove the cooled metal from the mold and use a forklift to move it to a storage area.
