Flame Treating Systems Inc in Durham, NC has purchased one natural gas fired draw batch oven from Wisconsin Oven to be used for tempering various steel parts. Flame Treating Systems Inc. provides customized flame hardening systems to customers along with in house flame hardening services. The addition of this tempering oven allows them to efficiently temper their customers’ parts in house.
The tempering oven has a maximum temperature of 1250°F and basket dimensions of 4’ W X 3’ H X 4’ L. Steel parts are loaded into the draw batch oven in the basket on two (2) stainless steel pier rails with the load capacity of 2,000 pounds gross. The recirculation system features a combination air flow arrangement that utilizes a 7,000 CFM @ 10 HP plug mounted blower. The combination airflow arrangement provides both horizontal and vertical upward airflow which maximizes heating rates and temperature uniformity of the product.
“We’re so glad to be able to temper parts in our own facility. We are starting to do a significant amount of flame hardening for customers in our shop now, so we needed a better solution than sending parts out for tempering. We installed the oven in the warehouse room adjacent to our 2000-lb. capacity spin flame hardening machine. Five days later it was in production, tempering batches of 800 lb. sprockets. That pretty much tells you what you need to know about the ease of installation. We’re looking forward to continuing to expand our services in the mid-Atlantic region for both localized hardening and tempering. Thanks, Wisconsin Oven.” Mark Sirrine, President – Flame Treating Systems Inc.
