The NEO™ Vacuum Oil Quench Furnace is a batch-type graphite insulated furnace designed to accommodate medium-sized workloads in an efficient, environmentally friendly, and economical manner. The main feature of the furnace is its ability to SAFELY and ENVIRONMENTALLY heat treat and oil quench workloads of alloys that require cooling rates that exceed high-pressure gas quenching’s practical capabilities.
The heating chamber is a double-walled, water cooled, horizontal loading vacuum chamber. An O-ring sealed rear door with pneumatic clamps allows for safe access of personnel for maintenance, adding work thermocouples to the load, and installation of temperature uniformity survey racks. Pneumatically operated sliding front door for loading and unloading workloads. Oversized water inlets and outlets allow maximum cooling water recirculation flow. Painted inner heating chamber wall minimizes build-up of contaminates and provides an easy to clean surface.
The internal gas cooling system includes a 30 HP motor which drives a high-speed centrifugal fan to recirculate the quench gas straight through the gas-to-liquid heat exchanger and then into the hot zone. The gas cooling is performed at a pressure of -5″ Hg and may be used to cool parts that require lower cooling rates for metallurgical purposes however is primarily used to cool the hot zone down as needed for re-loading or maintenance purposes.
The oil quenching system includes the loading and unloading hydraulic, linearly actuated, chain driven, mechanism and a 3,000-gallon vacuum-rated oil tank. Automatic or manual closed loop position and speed control for workload motion. Dual 10 HP impellers with variable frequency drives are used to circulate the oil across the parts during the quenching process. Alternatively, the parts can be quenched without oil circulation.
The SolarVac® Polaris is a PLC based control system with operator interface, recipe storage, alarm management, and data acquisition functions. Enables the operator to monitor, control, record, and quickly understand the status of the furnace operation. Includes Historian data acquisition and connectivity for the benefit of preventive maintenance, quality management, and production metrics. All controls and automation are housed in a suitable NEMA 12 control cabinet.
All Solar Manufacturing furnaces and replacement hot zones are designed for long life, easy maintenance, minimal downtime, and low cost of operation. Not only is each furnace fully tested prior to shipment, a Factory Service Engineer starts-up and field tests after installation. Every Solar Manufacturing furnace and hot zone carries a full one (1) year warranty.
