Surface Depths™ Reimagined

Surface® Combustion has always placed a high value on customer relationships. We believe that an equipment purchase is the beginning of something much more than a finite transaction. Our first-class customer service, rebuild/retrofit, and aftermarket parts departments are a testament to this way of thinking. A few years back, Surface released a mobile application to calculate case depth. It was used by our engineers and customers alike to complete quick, accurate calculations from the shop floor. It quickly became evident that there was an opportunity to provide our customers with even more complementary calculators to aid in easier recipe adjustments. We are proud to introduce you to the new Surface Depths™ and hope that you find it as helpful as we do. Current calculators include:Case Depth Calculator – This calculator provides a quick, back-of-the-envelope style estimate of case depth (or time to...

Cambridge Heat Treating Expands Adding Four Surface® Combustion Allcase® Furnaces

Maumee, Ohio:  Surface Combustion supplied two (2) new Allcase® Batch Integral Quench Furnaces to Cambridge Heat Treating of Cambridge, Ontario. Cambridge also purchased two (2) used Allcase furnaces in Ontario.  All four (4) Allcase furnaces are installed in the same line, along with a previously purchased 30”x30”x48” Allcase with top cool which are all serviced by Surface’s charge car, Uni-DRAW® Batch Tempering Furnaces, washers, and RX® Endothermic Atmosphere Gas Generator. Surface commissioned the new furnaces and continues to support the used equipment at its new home. The Allcase’s rugged design, ease of installation, and Surface’s aftermarket parts and service made this project a success. The 36”x48”x36” batch heat treat line greatly expands Cambridge’s capacity for carbonitriding, carburizing, neutral hardening, and added ferritic nitrocarburizing (FNC) and normalizing capacity with the atmosphere top cool chambers on the two (2) new Allcase furnaces. Says owner Peter Robbins, “We could not be happier with our...

Surface® Combustion Is Building a Smarter Charge Car

Surface® Combustion charge cars are proven, rugged material handling machines for batch heat treat lines. The cars transfer loads from washers to Allcase® furnaces to Uni-DRAW® temper furnaces. Our standard charge cars include single or double ended, Extended Reach™, System #1™, push/push, automation ready, and fully automated designs. The AP™ Torque system is now available on Surface Combustion Charge Cars and can transform an ordinary means of transport for workloads into a Predictive Maintenance Machine for an entire heat treat line. At minimum, the AP Torque system will eliminate the headaches of maintaining a mechanical clutch. Under the fullest utilization, the system can be used to track worn alloy in furnaces and alert users when replacement of alloy is required, before larger problems occur. The AP Torque System utilizes a Variable Frequency Drive to control the handler motor. The drive monitors and records the power required loading and unloading equipment. The VFD...

RX® Endothermic Atmosphere Gas Generators for Heat Treating

Surface® Combustion RX® Endothermic Atmosphere Gas Generators provide onsite generation of endothermic gas for controlled atmosphere furnaces performing metallurgical heat treatments such as carburizing, carbonitriding, ferritic nitrocarburizing (FNC), hardening, and annealing.  Industries using RX gas include Automotive, Energy, Mining, Agricultural, and Commercial Heat Treating.

Surface Combustion pioneered the development of RX gas to be used as the atmosphere for modern gas carburizing.  RX gas is produced by converting the incoming supply of natural gas[1] and air by catalyst and heat to a composition of 40% N2, 40% H2, and 20% CO.  The RX gas generator’s reliable production of consistent atmosphere chemistry with low oxidation, decarburization and soot potential revolutionized the heat-treating industry by enabling boost/diffuse carburizing, as well as atmosphere carbon control.

Our standard modular RX generator designs range from one (1) to five (5) tubes.  Surface offers short and tall tube...

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

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,...

Multiple-Chamber Vacuum Furnaces Provide Vacuum Advantages with Energy Savings

Early vacuum furnace designs began as single-chamber technology in which the heating and cooling required in a typical cycle were performed in the same chamber. While this is a cost-effective furnace design, there are dueling and sometimes completely incompatible design features that are necessary for optimum heating and optimum cooling. Better and thicker insulation helps with heating efficiency, but it likewise impedes the cooling rate and potentially the evacuation rate. Less or even no insulation is highly desirable for faster cooling rates and faster pump-downs, but this design creates havoc with uniform and efficient heating. High pressures and high velocities of cooling gases enhance cooling but are very detrimental to conventional hot-zone construction materials by causing erosion and distortion. Furnace designs with multiple chambers of other technologies are common (as seen with BIQ furnaces in atmosphere heat treating). This concept was the next logical progression in vacuum technology as well....
