The furnace systems were part of a major expansion by the customer to satisfy increased demand for large steel castings and weldments used as part of their equipment designs. Both furnaces are equipped with high efficiency, natural gas fired heating and recirculation systems that have demonstrated to exceed the requirements of AMS-2750 temperature uniformity.
Can-Eng Furnaces International Ltd. was selected as the vendor of choice largely due to the higher level of inhouse heat treatment equipment engineering capabilities and design experience. The customer was specifically impressed with Can-Eng’s controls capability to seamlessly integrate the systems Level 1 controls with the company’s existing plant supervisory and production control systems (Levels 2 & 3). Both systems integrated the company’s preferred PLC hardware which was upgraded to include a more flexible safety rated PLC over conventional hardwired safety circuits.
