Car Bottom Heat Treatment Furnaces
Car bottom annealing furnaces are used within the heat treatment of ready-made products in forging and pressing shops, as well as for the heat treatment of castings and weldments. Bulky parts are annealed while resting on annealing supports mounted on the furnace car, while smaller ones are loaded as stored in baskets or on grates. These furnaces are used for many various types of heat treatment – normalization, process annealing, heating for hardening or austenization, further for tempering or for annealing to release internal stresses after molding or welding. Commensurate to the above is the range of operating temperatures, from 250 °C to 1,150 °C, exceptionally up to 1,250 °C in the event of special materials. Where required, furnaces are fitted with a cooling system that will make it possible to carry out heat processing as a whole process, including controlled cooling zones and intense final cooling of the charge in the closed furnace without the need to open the door or to move the car out of furnace.
