The Steam Oven is a multiblock structure from the Railcraft mod. This machine is used to smelt items, using Steam as a fuel. The steam oven is built out of Steam Oven blocks in a 2x2x2 cube. The Steam Oven has nine input slots, and nine output slots. It costs 8000mB per operation, but smelts the entire first set of items in all input slots per operation. Each operation takes 12.8 seconds.
Containers of steam cannot be directly put into the machine; some form of automatic liquid transporting device, such as the Liquid Unloader, must be used.
