Vacuum Furnace heats and quenches load in same chamber.(Seco/Warwick Introduces 25 Bar Furnace).

Using helium as quench medium, 25 Bar HPQ(TM) Single Chamber Vacuum Furnace offers process alternative to vacuum furnaces using oil quench, minimizing problems such as disposal of spent quench fluids and requirements of parts washing and post heat treatment machining. Furnace is equipped with optional PreNit[R] and FineCarb[R] advanced LPC vacuum carburizing technology, which accelerates cycle time.

SECO/WARWICK has recently introduced a 25 Bar Single Chamber Vacuum Furnace as a process alternative to vacuum furnaces using an oil quench.

The 25 Bar HPQ(TM) delivers the same hardness properties as an oil quench, and when equipped with optional PreNit[R] and FineCarb[R] advanced LPC vacuum carburizing technology can reduce cycle time up to 50% 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

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. The furnace is equipped with PreNit[R] and FineCarb[R] advanced LPC vacuum carburizing technology that has reduced cycle times up to 50% in certain applications . 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:

o Disposal of spent quench fluids

o The requirement for a washer to clean parts

o Post heat treatment machining required to compensate for part distortion in oil

Reducing cycle times using Helium

Comparison chart of the thermal properties of a variety of common quench mediums

To maximize 25 Bar cooling, helium is used as a process atmosphere. Although more costly than nitrogen or argon, helium's thermal properties allow users to optimize quench hardening.

Due to the high costs associated with Helium as a process gas, recycling systems are available to recover and recycle the helium. Other than price, helium is a relatively easy gas with which to work. There are a large number of choices for supply systems. Helium follows the same installation guidelines (NFPA) as nitrogen.
