Treatnorte, a commercial heat treatment company, will add a new vacuum furnace to support vacuum heat treatment of tool steel, improving process control and consistency for components used in manufacturing applications.
The furnace joining Treatnorte’s machine park is a medium size system from SECO/WARWICK, a global manufacturer of heat treatment equipment with operations in North America. It is configured to provide a broad process range and production flexibility.
The round heating chamber allows processing of relatively large parts, while the combination of high-pressure gas quenching (HPGQ) up to 15 bar abs, combined with dedicated low-pressure carburizing (LPC) technology, enables complete process cycles for a range of steels used by Treatnorte’s clients. The furnace provides temperature uniformity, convection heating at lower temperatures, and directional cooling, supporting control of quenching processes for complex geometries.
The furnace configuration also incorporates FineCarb technology, SECO/WARWICK’s low-pressure carburizing solution carried out in a vacuum atmosphere, where carbon introduction is precisely controlled through successive pulses of carbon-bearing gases. This process allows for uniform and repeatable carburized layers with minimal part distortion and reduced cycle time.
The equipment will serve both the Portuguese and Spanish markets, where it will support ongoing tool steel heat-treatment operations. “The ability to independently perform vacuum hardening and carburizing processes significantly increases operations independence, shortens the supply chain, and allows for better quality control. FineCarb technology, combined with 15-bar gas quenching opens up opportunities for Treatnorte to win more demanding projects for [clients] in Portugal and Spain,” said Nuno Carvalho from Treatnorte.
