Abstract

The invention provides a vertical quenching furnace. The vertical quenching furnace comprises a furnace body; a heating chamber is arranged in the furnace body; a quenching pool is arranged below thefurnace body; a furnace cover is arranged at the top of the heating chamber; a furnace door is arranged at the bottom of the heating chamber; the lower part of the heating chamber communicates with afan through an air way; and a windlass is arranged in the furnace body. The vertical quenching furnace is characterized in that furnace door rails are arranged below the furnace door; two slide bars capable of sliding in the furnace door rails are arranged on the two sides of the furnace door; the two ends of each slide bar are in outward extension connection with straight arms; hydraulic oil cylinders are mounted below all the straight arms; an asbestos seal is arranged between the furnace door and the furnace body; and the bottom of the furnace door is connected with a pull rod. The verticalquenching furnace can preferably realize sealing of the furnace door, is better in temperature balance in the furnace, faster in opening, closing and locking of the furnace door and shorter in neededtime, and can effectively improve the quenching effect.

Description

Technical field: [0001] The invention relates to a vertical quenching furnace, which belongs to the technical field of heat treatment equipment. Background technique: [0002] The quenching furnace is a furnace that heats the workpiece before quenching. Quenching is to put the workpiece into the furnace and heat it to the quenching temperature above the critical point and keep it for a period of time, then quickly take the workpiece out of the furnace and put it into the quenching liquid (oil or water) for quenching. The heat source of the furnace can be electricity and fuel, and the temperature can be measured by a thermocouple. Furnaces using electricity, gas, and liquid fuels can be automatically controlled and regulated by instruments. [0003] The structure that the existing quenching furnace generally adopts is that the whole body of furnace is sealed in a steel structure frame. The quenching pool is located under the furnace, and the center of the heating furnace i...
