Surface® Combustion Allcase® BIQ Line Expansion at East Carolina Metal Treating

Allcase® Batch Integral Quench (BIQ) Furnace

Surface® Combustion, Inc. of Maumee, Ohio received a repeat order for an Allcase® Batch Integral Quench Furnace at the East Carolina Metal Treating facility in Raleigh, NC.  Identical to the previously commissioned Allcase furnace, the new Allcase is configured to process 36” wide by 48” long by 36” high workloads that weigh up to 4,000 lbs.  In addition to the two (2) Allcase furnaces, Surface supplied two (2) air cool stations, a scissors lift table and two (2) stationary load tables that integrate with an existing IQ line. According to Jamie Ramm, President of ECMT, the investment reflects the company’s long tradition of continually improving their ability to provide excellent service to their customers.

On the initial order, Surface incorporated a purchaser specified controls system to match the existing UPC controls. The new Allcase works seamlessly with ECMT’s existing charge car, tempers, and washer. Says Ramm, “As always our team did a great job but a special shout out to the Surface Combustion & UPC Teams involved in this project.  This was our first project with Surface and their reputation holds true as expected.”

The new Allcase BIQ features a Vertical Radiant Tube Heating System with direct spark ignition and flame monitoring, recuperated burners and plunge cooling.  A maintenance platform with access stairs allows for fast and easy maintenance.   An integrated Top Cool Chamber was provided to further expand process applications, a hallmark of the Allcase furnace which was invented for the greatest range of thermal processing; all case-hardening and non-case hardening applications under controlled atmospheres.
