Car Bottom Furnaces for Tempering
Precision Heat Treatment for Large Components
Product Introduction
Our Car Bottom Furnaces for Tempering are engineered to provide precise and uniform heat treatment for large, heavy, or irregularly shaped components after hardening. Tempering is a critical secondary heat treatment process that reduces the brittleness of hardened materials, relieves internal stresses, and improves ductility and toughness. These furnaces feature a robust movable hearth (or 'car') that facilitates easy loading and unloading of substantial workloads, minimizing thermal shock and ensuring consistent temperature distribution throughout the tempering cycle. Ideal for industries processing large castings, forgings, or fabricated structures, our car bottom tempering furnaces offer exceptional temperature control and uniformity, crucial for achieving the desired mechanical properties and structural integrity of the treated parts.

Working Principle
Car bottom furnaces for tempering operate by reheating hardened steel or other alloys to a specific temperature below the critical point, holding it at that temperature for a set period, and then cooling it, typically in air. The process begins with loading the pre-hardened workpiece onto the movable car outside the furnace. The car is then rolled into the heating chamber, which is sealed. The furnace gradually heats the components to the precise tempering temperature, allowing for the transformation of brittle martensite into a tougher, more ductile microstructure. The uniform temperature distribution within the furnace is crucial to ensure consistent tempering throughout the large or heavy load. After the soaking period, the car can be rolled out, and the tempered material is typically air-cooled, though other cooling methods can be employed depending on the desired properties. This controlled reheating and cooling process reduces internal stresses, improves toughness, and adjusts the hardness to the required level for the final application.
Process Flow
Material Loading
Hardened workpiece is loaded onto the movable car outside the furnace.
Heating & Soaking
Car is rolled into the furnace, and material is heated to target tempering temperature and held for a specified time.
Controlled Cooling
After soaking, the material is typically air-cooled to room temperature.
Unloading
Tempered material is removed from the car for inspection or further processing.
