Excellent performance of vacuum furnace
The pressure inside the chamber of a stove or furnace smoke into industrial furnace is lower than the atmospheric pressure. Vacuum furnace heating power, the heated surface oxidation, no decarburization, small deformation, the mechanical performance is good. Use the vacuum furnace smelting metal to remove impurities, less finished pinhole, segregation of small, good quality. Vacuum furnace is suitable for the high quality, high purity, refractory metal melting and heating, such as tungsten, molybdenum, tantalum, niobium, titanium, heat-resistant alloy steel smelting and magnetic materials, electrical materials of high strength steel, stainless steel, tool steel and die steel, heat treatment.
Before and after vacuum furnace appeared in the 1930 s. In 1927 the United States made electrical material vacuum annealing furnace. Vacuum since 1953 arc furnace power consumption in industry have been used for melting titanium sponge. Before and after the '50 s vacuum induction furnace is widely applied in industry. In 1960 the United States developed oil quenching vacuum furnace.
