  • Pre Pumped Vacuum And Protective Atmosphere Electric Furnace - China

    price: contact company for price

    It belongs to the exclusive patent of our company, patent No.:

    200520096581.X, is a high-energy-saving high-precision temperature

    control Pit cycle operation vacuum protection atmosphere furnace.

    Mainly used for aerospace, aircraft manufacturing industries, precision

    parts bright oxidation annealing without heat treatment, as well as

    automobile manufacturing industries, precision machinery manufacturing,

    precision mechanical or no oxidation not forging Bright decarbonization

    heating, quenching, annealing, tempering heat treatment, such as

    annealing and the use of the ball. In keeping with China's military

    aviation industry standards GJB509-98-88I type vacuum protective

    atmosphere furnace.

    Structure description:

    The shell is mainly made steel plate, and the furnace body are weldied by steel group. It blonga to a typical energy-saving lining, energy-saving 30-60%, resistance wire life may up to 5 years, the vacuum cans used 1Cr18Ni9Ti stainless steel plate or import high temperature-rolled stainless steel plate, automatic protection of welding used by large X-ray Inspection Room Inspection Test repression into. The furnace cover use stainless steel insulation cover. The cover panel and the tank body use double water cooling vacuum rubber sealing. 60KW above Pre-Pumped Vacuum and Protective Atmosphere Furnace cover installated stainless steel vacuum sealed fan which will enable inner temperature uniformity, furnace panels are installed on the vacuum interface, Interface sent to protect the atmosphere, vacuum Pressure Gauge. Lid and furnace tank will be available throughout the workshop lane vacuum cans hanging out natural speed forced air cooling or water cooling for handling the workpiece. In order to enhance production efficiency, you can order two alternating vacuum tank to work continously. 60KW above Pre-Pumped Vacuum and Protective Atmosphere Furnace divided into multi-zone temperature control, power distribution according to the law warming. Using multiple microcomputer procedures SCR counters, temperature control, automatic show that the measured temperature, the temperature of heating value and slope settings, over-temperature alarm and automatic process Curve Records. Can not determined in paragraph 8 of curves, temperature control accuracy soil 1℃. When used as ball annealing, process requires 780℃ to 680℃ rapid furnace cooling system should be raised in order, the installation of the heater out of the furnace heat of nitrogen nitrogen rapid thermal cycle to reduce nitrogen temperature, cold nitrogen get into the tank faster cold circulatory system.
