The Car Bottom Annealing Furnace, also known as a Bogie Hearth Annealing Furnace or Trolley Type Annealing Furnace, is a heavy-duty industrial heat treatment furnace specially designed for annealing, stress relieving, normalizing, and other thermal processes of large and heavy metal components.

Unlike traditional fixed hearth furnaces, a car bottom annealing furnace features a movable furnace hearth (car/trolley) that allows large workpieces to be loaded and unloaded easily. This design is especially suitable for oversized components that cannot be handled by conventional furnaces.
