Specialty Steel Treating selected Super Systems Inc. process controls and DAQ system to manage and collect data for nitriding furnaces at its Fraser, Mich., heat-treating facility.

Specialty Steel Treating (SST) selected Super Systems Inc. (SSi) process controls and DAQ system to manage and collect data for nitriding furnaces at its Fraser, Mich., heat-treating facility. Programmable temperature controllers with cascade capability will be implemented across multiple furnaces. Process control will be handled in a centrally located SSi-engineered three-door control panel using SuperDATA for supervisory control, data acquisition and historical trend monitoring. This multi-furnace installation is part of an ongoing process by SST to replace and update all of the facility’s controls.            

The installation at SST will provide verification of gas flow of ammonia, nitrogen and DA. Along with all new controls, SSi-designed H₂ analyzers will be used to measure and record the %DA of the nitriding process. The control system includes extensive alarms and recording, incorporating measuring and alarming of fan rotation as well as automatic cycle control and a recipe programmer for complete process management.
