High-temperature billet heating and controlled normalizing cycles for producing precision-forged automotive and engineering components.
Hot forging requires steel billets to be uniformly heated to 1100-1250°C before shaping under mechanical or hydraulic hammers. LPG's high flame temperature and controllable combustion ensures uniform billet temperature - eliminating cold zones that cause forging defects and tool breakage.
Normalizing at 850-900°C following forging relieves internal stresses and refines grain structure for improved mechanical properties. LPG-fired normalizing furnaces provide the controlled atmosphere and temperature uniformity this process demands.
LPG burners with recuperators achieve ±15°C uniformity across billet cross-sections, reducing forge rejects.
High heat release reduces billet heating time from 45 min (electric) to under 20 min for typical sections.
Controlled LPG atmospheres during normalizing prevent decarburization of the metal surface layer.
LPG bulk installations support large forging presses consuming 300-1000 kg/day of gas.
Bulk piped LPG supply is also available for high-volume consumers. Contact BPCL to discuss your requirements.
