Car bottom furnaces represent a special form of batch furnace and are particularly suitable for changing component dimensions. It is possible to move the furnace bottom out of the furnace, usually on rails. The batch is positioned and moved into the furnace. Thus, batches can be changed in short time and residual heat can be used to save energy.
