Abstract

The invention discloses a quenching furnace, which comprises a hearth, and a blanking channel which is arranged at a discharge end of the hearth and is communicated with a quenching groove; wherein an oil curtain mechanism is arranged between the lower part of the blanking channel and the quenching groove and comprises an oil curtain chamber, the upper end of the oil curtain chamber is communicated with the blanking channel and the lower end of the oil curtain chamber is communicated with the quenching groove; an oil injection pipe which transversely extends and an arc-shaped oil curtain plate which is positioned below the oil injection pipe are respectively arranged on two opposite side walls of the oil curtain chamber; a plurality of nozzles facing towards the arc-shaped oil curtain plate are formed on the oil injection pipe and are axially distributed along the oil injection pipe; and the arc-shaped oil curtain plate is arched downwards and extends towards the blanking channel. Theinvention provides the improved oil curtain mechanism on the basis of related patents, a large amount of steam and a large amount of oil smoke in the quenching groove are effectively prevented from entering the hearth, the problem that an oil duct is frequently blocked is solved, and the maintenance cost of equipment is saved.

Description

technical field [0001] The invention belongs to the field of heat treatment equipment, in particular to a quenching furnace. Background technique [0002] When the workpiece is quenched, it needs to be heated at 850°C in the quenching furnace cavity. When the workpiece in the furnace runs to the end of the conveyor belt, it falls into the blanking channel, immerses in the quenching tank to cool, and finally lifts the workpiece through the quenching tank lifting frame to complete the quenching process. During the quenching process, a large amount of water vapor and oil fume will rise into the furnace, and the workpiece will easily splash into the furnace when the workpiece falls into the quenching tank, resulting in a decrease in the quenching quality of the workpiece. [0003] At present, the latest Chinese patent 200820199488.5 discloses a splash-proof quenching furnace, which has been improved accordingly. This quenching furnace mainly includes a furnace and a quenching ta...
