Car Bottom Furnaces for Annealing
Optimized Solutions for Material Softening
Product Introduction
Our Car Bottom Furnaces for Annealing are robust, high-capacity heat treatment systems designed for the precise and uniform annealing of large, heavy, or irregularly shaped components. Annealing is a critical heat treatment process used to soften materials, improve ductility, relieve internal stresses, and refine grain structure, making them more workable and less brittle. These furnaces feature a movable hearth (or 'car') that can be loaded outside the furnace and then rolled into the heating chamber, significantly simplifying the handling of substantial workloads. This design minimizes heat loss during loading and unloading and ensures consistent temperature distribution throughout the annealing cycle. Ideal for industries processing large castings, forgings, or fabricated structures, our car bottom annealing furnaces provide exceptional temperature uniformity and controlled cooling, ensuring optimal material properties for subsequent processing or end-use applications.

Working Principle
Car bottom furnaces for annealing operate by heating large and heavy components to a specific temperature, holding them at that temperature for a set period, and then slowly cooling them to achieve desired metallurgical properties. The process begins with loading the workpiece onto a movable car (hearth) outside the furnace. Once loaded, the car is rolled into the heating chamber, which is then sealed. The furnace heats the components to the desired annealing temperature, typically above the recrystallization temperature but below the melting point. After the soaking period, the furnace slowly cools the material, often by controlled furnace cooling or slow air cooling, to allow for grain growth, stress relief, and the transformation of the microstructure to a softer, more ductile state. The car bottom design facilitates easy handling of massive loads and ensures uniform heating and cooling throughout the entire cycle, which is crucial for achieving consistent annealing results in large components.
Process Flow

Workpiece is loaded onto the movable car outside the furnace.
Heating & Soaking
Car is rolled into the furnace, and material is heated to target annealing temperature and held for a specified time.
Controlled Cooling
Material is slowly cooled inside the furnace or by controlled air cooling.
Unloading
Annealed material is removed from the car for further processing or inspection.
