trolley vacuum bright annealing furnace

    trolley vacuum bright annealing furnace is the most common type of trolley vacuum bright annealing furnace. It is a standard energy-efficient furnace operation period, mainly for length bright annealing of metallic materials, such as steel, steel bar lines, special steel, high speed steel, alloy steel, fasteners, copper, copper, brass, copper row, wire and cable, wire, drawing, aluminum wire, environmental protection equipment, machinery supporting enterprises, military and other industries heat treatment plant heating.

    Vacuum bright annealing furnace generally use electric heating method, the material will be processed in the furnace of special platform loaded baskets, pushing along a track into a stainless steel furnace. Furnace and water-cooled lid rubber seal to ensure air tightness, with vacuum function. As the workpiece is heated evenly, improve heating and cooling rate, in addition to a separate temperature-controlled partition, the other in the heat blower lid configuration and diversion means for the implementation of protective atmosphere furnace strong convective circulation. During the heat treatment, the material is always placed under high purity nitrogen gas or hydrogen gas protection, so that the treated material surface brightness is no oxidation.

    Vacuum bright annealing furnace from a high temperature, medium temperature and low temperature annealing furnace of the points, the highest temperature in a high temperature furnace within 1000 ℃, the temperature within the furnace at 800 ℃, low temperature annealing furnace within 650 ℃, were selected according to their product features, furnace size, load orders according to customer requirements.

    Vacuum bright annealing furnace is controlled by contactors, SCR, solid state, module, electronic digital display, intelligent digital display, computer, PID, PLC, remote control, centralized control, program control, are recorded in the park map, long multi-point chart There paperless recorder, can be applied to liquid crystal paperless recorder records.

    Vacuum bright annealing furnace from the furnace body, stainless steel furnace, heat blower, vacuum pump, protect the pipe valve, pressure flow meter, stainless steel baskets, special charging stand, baskets sliding devices, electronic control systems and other components. The furnace shielding gas flow adjustable, with the furnace pressure overpressure alarm and automatically reducing pressure function. Imported intelligent temperature control device, three sections according to process     requirements for automatic PID precise temperature control, automatic timing insulation, to automate the entire process of heat treatment temperature control. The entire process and the temperature change U disk records are stored on a computer visual display and print them out. Electromechanical system with safety interlock protection device, fault diagnosis, sound and light alarm, so that safe operation of equipment. Lightweight insulation brick hearth and heavy brick masonry, heating elements band resistance wire and resistance heating furnace shell is made of steel and steel production, lid with mechanical drive; specifically configured according to customer requirements and design and is equipped with oven .

    Optional vacuum bright annealing furnace box-type atmosphere protection furnace, Pit vacuum furnace, horizontal vacuum furnace, car vacuum bright annealing furnace, etc., for a variety of metal materials products for annealing, tempering, normalizing heat treatment purposes.
