Introduction
The vacuum oil quenching furnace is a graphite furnace, and the heat shield is graphite felt. The electronic control system has a high degree of automation, is stable and reliable. Vacuum oil quenching furnace is mainly used for bright quenching and annealing of alloy steel, tool steel, mold steel, high-speed steel, bearing steel, spring steel, stainless steel and other materials or vacuum sintering of ceramic materials and cemented carbide; vacuum brazing of metal materials wait.
Features
● Graphite tube is used as the heating element , which has a long service life and is easy to maintain.
● Composite gate valve has good heat insulation and air isolation effects.
● Double-chamber structure, the rear chamber is a heating chamber; the front chamber is a cooling chamber, which can be used for oil quenching and air cooling. The upper part is a gas quenching chamber, equipped with an air cooling system; the lower part is an oil quenching chamber, equipped with a lifting mechanism, a feeding and discharging mechanism, an oil stirring device and an oil heating device.
● Lifting mechanism: It is driven by a three-speed gear motor outside the furnace, and drives the lifting truck through the screw and nut mechanism. The lifting truck has three speeds. The slow speed is used when feeding and retrieving materials. The slow starting speed, fast oil entry and slow speed entry are used during oil quenching.
● Oil stirring system: The motor reducer drives the agitator under the feed truck. The baffle can promote the reasonable circulation flow of vacuum quenching oil and improve the cooling capacity of quenching oil. The stirrer is a standard part with low noise and high efficiency.
● The workpiece transfer mechanism is smooth and flexible, safe and reliable.
● The furnace cover of the air-cooling chamber adopts a staggered-tooth flange ring structure to ensure sealing in both positive and negative pressure directions.
