As one of the prominent bogie hearth annealing furnace manufacturers in India, Maan Global Industries offers high-capacity, PLC-controlled annealing systems trusted by industries across automotive, oil & gas, defense, tool & die, and pressure vessel sectors.
This article provides a complete technical guide on bogie hearth furnaces used for annealing, why they’re preferred in industrial heat treatment, and why partnering with experienced manufacturers of bogie hearth furnace for annealing ensures long-term process efficiency and metallurgical precision.
What Is a Bogie Hearth Furnace for Annealing?
Table of Contents
A Bogie Hearth Furnace is a batch-type furnace with a movable car (bogie) that transports the load into and out of the heating chamber. During the annealing process, metals are heated to sub-critical or recrystallization temperatures (typically 550°C to 950°C) and held for a fixed duration, followed by controlled cooling. This softens the metal, removes internal stresses, improves ductility, and refines grain structure.
The design enables:
-
Loading of heavy and oversized components (up to 50 tons or more)
-
Uniform heating with multiple zones and high temperature accuracy
-
Safe, ergonomic material handling using motorized bogie rails
As experienced bogie hearth furnace manufacturers in India, we engineer furnaces specific to your product geometry, load volume, and temperature cycle requirements.
