Solar Manufacturing Ships Largest Car Bottom Vacuum Furnace to China

Solar Manufacturing announces it has shipped the largest vacuum car bottom furnace ever manufactured to Baoji Titanium Industry Co., Ltd. in Shaanxi, China. Baoji Titanium is the largest producer in China of all types of titanium and titanium alloy products supplying domestic and international customers in the aerospace, energy, chemical, medical and automotive industries. The furnace will be used primarily for the annealing of large CP1 titanium coils.

The furnace is a Solar Manufacturing model HCB-120432-2EQ horizontal, car bottom furnace with powered loading systems at both front and back ends of the furnace. The furnace work zone measures 80″ wide x 80″ high x 432″ long (36 feet long) with a gross weight capacity of 150,000 pounds. The hot zone incorporates a Flexshield graphite hot face backed by multiple layers of high purity graphite felt for operation up to 2250°F.

“Curved graphite heating elements provide for rapid and uniform heating with multiple zones of control along the length of the hot zone to assure uniformity in accordance with AMS 2750D,” said Rick Jones, vice president of international sales. “Dual vacuum pumping systems each consisting of a 35″ diffusion pump, a 48″ high vacuum valve and high capacity roughing pumps to provide processing in the low 10-5 Torr range, are also featured. Gas quenching is accomplished by using two external 300 HP turbine blower systems designed to recirculate argon gas at 2 bar positive pressure and at very high velocities,” he explained.

Solar Manufacturing designs and manufactures all types of vacuum heat treating and brazing furnaces and offers replacement hot zone and spare parts for various vacuum furnace brands.
