Bogie Hearth Furnace

• Temperature Range : Upto 1500°C
• Standard Applications : Annealing, Stress Relieving, Hardening, Tempering, Normalising
• Insulation Vacuum Formed Ceramic Fibre Boards / Ceramic Fibre Blanket & Module / Brick Lining

When parts or charges that are to be loaded onto a furnace are heavy and require material handling facility for loading and unloading, a moving bogie or hearth is provided to make this easier. Once the hearth moves out of the furnace heating chamber parts can be loaded by means of an electrical overhead crane (EOT), gantry system or mobile crane forklift mechanism. If required, special charge loading mechanisms can also be provided based on the user�¢ï¿½ï¿½s job profile, lack of material handling facility or overhead space constraint. The bogie movement is motorized for easy handling. Similarly the door movement would be with motorized gear drives or hydraulically pneumatically actuated. Our standard bogie hearth furnaces can go up to 1500���°C, however any special requirements beyond this can also be taken up with a custom design. High temperature applications include sintering, hardening, annealing and normalizing whereas lower temperature applications include tempering and stress relieving. The control system is provided with options to set and control the ramping rate, soaking rate and cooling rate depending on the process cycle, the option of PLC based control is also available. The furnace can be used in open atmosphere or controlled atmosphere as per application. We provide designs with in and out bogie (hearth) movement as well as through and through double door bogie movement if required for an assembly line or process line Etc.
