SECO/WARWICK has recently introduced a 25-bar single chamber vacuum furnace as a process alternative to vacuum furnaces using an oil quench. The HPQtm delivers the same hardness properties as an oil quench, and when equipped with optional PreNit® and FineCarb® advanced LPC vacuum carburizing technology can reduce cycle time up to 50 percent in certain applications.
For a limited time SECO/WARWICK is offering free trials in their R&D facility to allow companies interested in the process an opportunity to receive a full metallurgical report for their samples without risk. SECO/WARWICK will provide additional field support for customers investing in this new technology to assure the system is installed correctly and fined tuned to be in operation quickly and efficiently.
The 25-bar furnace, using helium as the quench medium, lowers distortion and eliminates parts washing, saving you time and money upstream and downstream of the equipment. With the single chamber furnace the load is both heated and quenched in the same chamber, saving equipment cost and simplifying the entire operation. This furnace minimizes many of the problems associated with oil quenching:
• Disposal of spent quench fluids;
• The requirement for a washer to clean parts;
• Post heat treatment machining required to compensate for part distortion in oil.
Due to the high costs associated with helium as a process gas, recycling systems are available to recover and recycle the gas. Other than price, helium is a relatively easy gas to work with. There are a large number of choices for supply systems. Helium follows the same installation guidelines (NFPA) as nitrogen.
