Custom Manufacturing of Car Bottom Furnaces for the Forging Industry

Car Bottom Furnace
Car Bottom Furnace

A customer in the forging industry commissioned CHE International to design and fabricate two custom car bottom furnaces, used in producing seamless forged rings. These furnaces were designed with a 50,000 lb capacity, achieved with the integration of special alloy grids and piers along with ceramic fiber flooring. The alloy grids feature low deflection at the elevated temperatures, and the floors and piers used are able to absorb an abundant amount of heat. The direct gas fired units were fabricated and fully assembled on-site, and subjected to an in process and post-production temperature uniformity survey to verify quality and ensure the upholding of AMS 2750 D standards.

One furnace operates at a temperature range of 600-1200 °F, and the other at 1200-1450 °F. Overall dimensions of the completed units were 8' X 18' X 16', built after a turnaround time of 16 weeks and delivered to the customer in Georgia, USA. Customer satisfaction with these units led to a continued relationship, completing 2 additional furnaces for the client.
