Carburizing furnace for metal forging heat treatment and carburizing method thereof

Abstract

The invention relates to the technical field of metal forging, and discloses a carburizing furnace for metal forging heat treatment and a carburizing method thereof. The carburizing furnace comprises a furnace shell, a furnace cover is movably installed at the top end of the furnace shell, a heating element is fixedly installed in the middle of an inner cavity of the furnace shell, and a furnace tank is fixedly installed on the inner side of the heating element. According to the carburizing furnace, red light which is transmitted from the interior of the furnace and is emitted due to high-temperature burning is blocked by adopting a quartz tube, heat light conduction of the pipe wall of an exhaust pipe is effectively reduced, if the red light is too bright, the light is reflected back to the quartz tube and the exhaust pipe by utilizing a reflecting plate, heat light loss is avoided, and heat radiation is blocked; heat conduction of air can be effectively blocked through an isolating pipe, low-temperature air in the external environment is intercepted, the heat preservation effect is further promoted, then barrier cotton is utilized to reduce the amount of air permeating inwards, and heat preservation is promoted; and flame light refraction and convergence are conducted through an enoscope, the quartz tube conducts heating and heat preservation on the outside of the exhaust pipe in time, and metal dusting of the exhaust pipe is effectively reduced.

Description

Technical field [0001] The present invention relates to the field of metal forging techniques, and is specifically a carburizing furnace and a carburizing method thereof forging a metal forging heat treatment. Background technique [0002] The carburizing furnace is a new type of energy-saving cycle operating heat treated electric furnace, which is mainly composed of a furnace shell, a furnace lining, a blast fan, a furnace lifting mechanism, a heating element and a mass can, and a carbon power atmosphere in a high temperature environment. For metal, gas-carbonic heat treatment, due to uniform temperature of the carbon furnace, the workpiece is quickly carburized, and thus it is widely used in the hot forging process. [0003] Among them, the carbon power atmosphere used in the carburizing furnace is generally Co, CH 4 N 2 Wait, it contains certain harmfulness, so that the exhaust pipe is generally disposed from the furnace in the carburizing furnace apparatus, and the furnace is...
