Hardening furnace

Abstract

The invention discloses a hardening furnace, and belongs to the field of metal heat treatment equipment. According to the hardening furnace, a water tank and a smoke sucker are installed in a coolingarea. When a workpiece enters a charging basket and quickly enters a water pool, the smoke sucker starts up at the same time to suck the smoke and stores the smoke in the smoke sucker. When the temperature displayed on a temperature display screen is low, a smoke switch is turned on to send the smoke in the smoke sucker to a functional main body so that the smoke can be recycled to raise the temperature and reduce the pollution. Additionally, an operation switch is turned on, the water tank sprays water into the cooling area through spraying balls so as to remove oil smoke which deposits on the inner wall in quantity and discharge the oil smoke out through a drain pipe, and consequently, it is avoided that cleaning is troublesome, no carbon deposition occurs, the service life of the hardening furnace is prolonged, the quality of quenching workpieces is improved, and the rejection rate of the workpieces is decreased. With the hardening furnace, it is solved that because a hardening furnace in the prior art is poor in smoke exhaust effect, extra oil smoke deposits on the inner wall or the bottom in quantity and forms a carbon deposition layer under the high temperature, and cleaningis troublesome.

Description

technical field [0001] The invention belongs to the field of metal heat treatment equipment, and in particular relates to a quenching furnace. 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. Heat treatment quenching furnace is a general equipment necessary for metallurgy, cast steel, forging, and machining industries to meet the requirements of workpiece use. [0003] Some quenching furnaces in the prior art often include structures such as a furnace body, a material basket, a push head, and a push block. In actual use, the quenching fur...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a quenching furnace for the problem that the exhaust effect of the current quenching furnace is poor, resulting in a large amount of excess oil fume being deposited on the inner wall or bottom, forming a carbon deposit layer at high temperature, and cumbersome cleaning.
