Lindberg/MPH Ships Two Pacemaker Furnaces to be Used for Carburizing and Hardening

Press release date: Oct 20, 2017

Riverside, MI – October 20, 2017 – Lindberg/MPH announced the shipment of two electrically heated Pacemaker integral quench furnaces. The Pacemaker IQ furnaces will be used for carburizing and hardening applications. These integral quench furnace systems provide a total solution for your heat-treating processes.

The Pacemaker furnaces have maximum temperature ratings of 1850°F, work chamber dimensions of 24” W x 36” D x 24” H, and feature upper atmosphere cooling chambers. A programmable control system provides full automation of the load and carbon control. The programmable logic controller also performs all data collection functions for process variables. Atmosphere carbon potential is controlled with automatically adjusting flowmeters and an oxygen probe. The equipment status screens are visible on the HMI screens.

The equipment drive mechanism pushes the workload into the furnace and performs a carburizing process under atmosphere. The workload is heated with robust low voltage Corrtherm heating elements which are well suited for a high carbon potential atmosphere. A discharge drive system pushes the workload out of the furnace and onto a quench elevator. The load is then either lowered into a preheated oil quench tank for fast, circulated cooling or is elevated for a slower atmosphere cool.

“Lindberg has manufactured over 1,000 similar Pacemaker units since the early 1960’s. We offer both electrically heated and gas fired systems with a full range of companion equipment. Sizes range from a lab-sized 12” x 24” x 12” unit for 250 pound loads to our largest 48” x 72” x 36” furnace for 6,000 pound loads.”- Bill St. Thomas, Business Development Manager
