Abstract

The invention discloses a vacuum high-pressure gas quenching furnace with a diversity channel. The high-pressure gas quenching furnace with the diversity channel comprises a furnace body, wherein a centrifugal vane wheel is arranged on the rear end of the furnace body. The invention provides the high-pressure gas quenching furnace with the diversity channel, which is ingenious in structure arrangement and reasonable in arrangement; a hot air flow firstly and completely passes through a whole heat exchanger and then enters the centrifugal vane wheel, so that a better heat exchange effect and aneffect on protecting the centrifugal vane wheel against being impacted by a high-temperature air flow are achieved; the opening and the closing of each cabin door of a heating area and each baffle plate of a heat exchanger cabin port are automatically controlled through a program, and a specific gas quenching and cooling channel way is combined and built, so that workpieces can be quenched quickly and uniformly, and workpiece deformation is reduced; compared with a traditional square-shaped heating area gas quenching furnace, the novel structure is provided with the diversity gas quenching channel, so that a more uniform quenching effect can be achieved on large-sized workpieces, and the deformation is reduced maximally; and during quenching, a cooling air flow is more uniform to distribute, a quenching gas flow is larger, and the quenching time is shorter.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a vacuum high-pressure gas quenching furnace with multiple channels. Background technique [0002] Vacuum high-pressure gas quenching furnace is a vacuum heat treatment equipment with four-chamber graphite heating zone, high-power heat exchanger, diverse gas quenching flow channel and reversing mechanism, high-pressure inert gas quenching and cooling. Usually graphite heating zone, inert gas convection heating and vacuum heating are used, and the maximum heating temperature can reach 1350 degrees. When quenching, it is filled with high-pressure inert gas, and the high-efficiency heat exchanger and high-power fan are used for rapid heat exchange. The inert gas can reach a pressure of up to 20bar for rapid quenching, and can also achieve isothermal quenching. The vacuum high-pressure gas quenching furnace is mainly used for tool steel , Die steel, other high-alloy...
