C.I. Hayes: Small Batch Vacuum Furnaces
3
Filling the need for light production, tool room, research and development applications, the C.I. Hayes “VCQ-ME” Small Batch Vacuum Furnace is ideal. This furnace offers great flexibility, having the ability to heat treat low, medium and high carbon steels, alloy steels, tool steels and stainless steel materials. It consists of a high temperature heat chamber with integrated sealed oil quench chamber that does not require a pit. Programmable controls provide tailored thermal profiles including three modes of cooling - oil quench, gas cooling (above oil) and vacuum cooling. The “VCQ-ME” Small Batch Vacuum Furnace can be supplied with an automatic or manual work transfer system. Processes performed in this furnace are many, including annealing, brazing, carburizing, carbonitriding, hardening and sintering.

Though low vacuum levels are settable during heating, depending upon the materials being processed, inert gas is backfilled to some minimal partial pressure during part transfer into the oil. At that time, the quench oil is circulated at the appropriate speed to achieve fast cooling. Of course, parts may be vacuum cooled or gas cooled above the oil instead. Component Selection Each component of the furnace has been engineered, not just for temperature, process and vacuum conditions, but for long usage and ease of maintenance. Access to the heat chamber and quench area are provided. Proven suppliers are used in selection of vacuum, hydraulic and controls components. The “VCQ-ME” Small Batch Vacuum Furnace is available in two standards sizes and various temperature ranges. Optional features are always available.
