Double-chamber high-pressure gas-quenching vacuum furnace

Abstract

Disclosed is a double-chamber vacuum furnace of high-pressure gas quenching, which belongs to the field of heat treatment industry, in particular to a high-pressure gas quenching vacuum furnace composed of a quenching chamber and a heating chamber. Most of present high-pressure quenching vacuum furnaces are of a single chamber structure, and in the process of air quenching, cooling and heating are proceeded in the same chamber, thereby the whole heating chamber needs to be cooled down at the same time of quenching, when the second batch of pieces are needed to be quenched, the whole heating chamber needs to be heated again, thereby greatly wasting power energy. The main purpose of the device is to preserve the temperature of the original heating chamber in the secondary processing, thereby saving power energy and improving production effect, and the device is mainly composed of a water-cooled furnace wall with double walls, a middle gate valve, the heating chamber, a cold chamber feeding mechanism, a high-pressure fan, a heat transfer device, a flow guide device, a vacuum system, an electric control system and the like. After being heated in the heating chamber, pieces are taken out by the feeding mechanism to be transmitted to a cold chamber quenching area in which inactive gas is then filled in, and the high-pressure fan on the top portion of the invention is opened to proceed forced cooling and quenching, thereby on one hand, the taking out of the pieces need not to cool down the whole heating chamber, which improves cooling speed and quenching degree of the pieces, on the other hand, the heating chamber is in the state of continuous heat preservation, which provides energy source for the production of the second batch of pieces.

Description

technical field [0001] The invention belongs to the field of heat treatment industry, in particular to a high-pressure gas-quenching vacuum furnace composed of a quenching chamber and a heating chamber. Background technique [0002] Most of the current high-pressure gas quenching vacuum furnaces have a single-chamber structure. During the gas quenching process, since cooling and heating are carried out in the same room, the entire heating chamber must be cooled down at the same time as quenching. When the second batch of workpieces are quenched, the entire heating chamber must be reheated, which greatly wastes electric energy. The main purpose of this equipment is to solve the problem of maintaining the temperature of the original heating chamber during secondary processing, which not only saves electric energy, but also improves production. potency. Contents of the invention [0003] The present invention mainly changes the original single-chamber furnace into a double-c...
