Bogie-Hearth Stress-Relief Furnaces

Overview

Bogie-hearth (car-bottom) furnaces are the standard solution for stress-relieving large welded structures, castings and machined parts. The load is craned onto a motorised car outside the furnace, and the car is then driven into the chamber — no crane handling inside the furnace.

Burner or heater arrangement, sealing systems and multi-zone control are designed to keep temperature uniform across large, heavy loads, with full documentation of every heat treatment cycle.

Typical applications

• Stress relief of welded fabrications
• Heavy castings
• Pressure-vessel parts
• Machine frames and structures
