Solar Manufacturing announces the sale of two new vacuum furnaces to Kentucky Heat Treating of Winchester, KY. The equipment was purchased to satisfy expanding customer demands relating to various areas of tool steel processing.
The two identical furnaces are Solar Manufacturing models HFL-3872-10IQ with work zones that measure 24" × 24" × 72" with a gross load capacity of 2,000 lbs. The furnace insulation consists of 1" thick foil-faced graphite board backed by three layers of 0.5" high-purity graphite felt, all supported within a heavy-duty 0.090"-thick #304 stainless steel structure. The internal quench systems can achieve cooling rates at pressures up to 10 bar positive produced by the high velocity of quench gas. The internal 300-hp drive motor and radial fan wheel re-circulates quench gas directly into the hot zone and onto the workload through tapered graphite nozzles and then through the all-copper, water-cooled, high-efficiency heat exchanger. The furnaces have a maximum operating temperature of 2,500oF and a vacuum system included for operating in the 10 to 3 Torr range using Stokes model 412 and model 615 vacuum pumps.
