What does a Core Oven Tender do?
Tends baking oven that hardens and strengthens green sand cores used in casting metal: Loads cores on racks, trays, or carts, and pushes them into oven. Lights gas- or oil-fired furnace and turns valves to obtain specified temperature; or sets thermostat and closes switch to heat element in electric furnace. Closes oven door and allows cores to bake for specified time. Opens oven door and removes cores. May adjust baffle plates that direct flow of heat in oven.
