High Temperature Car Bottom Furnace for Heavy Load Steel Heat Treatment
A high temperature car bottom furnace is a batch-type industrial heat treatment system designed for processing heavy and oversized metal components. The furnace utilizes a motorized car platform to transport workpieces into a sealed heating chamber, enabling controlled thermal processing with uniform temperature distribution. It is widely used for annealing, normalizing, tempering, and stress relieving of large steel structures, castings, and forgings.
Working Principle of Car Bottom Furnace
The furnace operates based on resistance heating or gas combustion, depending on the configuration. Heat is transferred to the workload through a combination of radiation and forced convection. A high-efficiency circulation fan ensures uniform temperature distribution throughout the chamber.
The loading car is driven into the furnace chamber and sealed at the entrance. Temperature is precisely controlled via PID or PLC-based control systems, allowing accurate execution of heat treatment cycles.
Heat Treatment Process Capability
Improves ductility and reduces internal stress in steel components.
Refines grain structure for improved mechanical properties.
Adjusts hardness and toughness after quenching.
Eliminates residual stress in welded or machined components.
