Commercial heat treater Mid-South Metallurgical purchased three AFC-Holcroft furnaces to increase production capability at its Murfreesboro, Tenn., facility. The equipment consists of a UBQ (universal batch quench) integral-quench furnace, two UBT (universal batch temper) furnaces and an EZ™ generator. It was integrated into Mid-South’s existing batch furnace line and has been installed and commissioned. The expansion will significantly increase Mid-South’s capacity for carburizing, carbonitriding, neutral hardening, normalizing, annealing and stress relieving of metal components.
