Abstract
A double-chamber high-pressure gas quenching vacuum furnace belongs to the field of heat treatment industry, in particular to a high-pressure gas quenching vacuum furnace consisting of a quenching chamber and a heating chamber. The current high pressure gas quenching vacuum furnace is mostly of a single-chamber structure, and in the process of gas quenching, because cooling and heating are carried out in the same chamber, the whole heating chamber must be cooled down simultaneously when quenching is carried out, and when a second batch of workpieces are required to be quenched, the whole heating chamber must be reheated, so that the electric energy is greatly wasted. The equipment mainly comprises a double-wall water-cooled furnace wall, a middle gate valve, a heating chamber, a cold chamber feeding mechanism, a high-pressure fan, a heat exchanger, a flow guide device, a vacuum system, an electric control system and the like. When the workpiece is heated in the heating chamber, the workpiece is taken out by the feeding mechanism and moved into a quenching area of the cold chamber, then inert gas is filled, and a high-pressure fan at the top is opened for forced cooling quenching. Therefore, on one hand, the workpiece is moved out without cooling down the whole heating chamber, so that the cooling speed and the hardenability of the workpiece are improved, and on the other hand, the heating chamber is still in a continuous heat preservation state, so that energy is provided for the production of a second batch of workpieces.
Description
Technical field
The present invention is the heat treatment industry field, particularly a kind of high-pressure gas-quenching vacuum furnace of being made up of quenching chamber and heating chamber two Room.
Background technology
Present high-pressure gas-quenching vacuum furnace mostly is single cell structure, in the process that gas is quenched, because cooling and heating are same indoor carrying out, so when quenching, whole heating chamber must be cooled down simultaneously, in the time second batch of workpiece need being quenched, also must reheat whole heating chamber, wasted electric energy so greatly, the main purpose of this equipment is when solving secondary processing the temperature of former heating chamber to be kept, and has so both saved electric energy, has improved again to produce and has renderd a service.
Summary of the invention
The present invention changes original one-way fired furnace into double-chamber structure, and promptly the front is the high pressure gas quenching cooling room, and the back is a heating chamber.When workpiece takes out immigration cold house quench zone by feed mechanism after the heating chamber heating, charge into rare gas element then, open the high pressure positive blower at top and force Cooling Quenching.Shifting out of workpiece do not need whole heating chamber is cooled down so on the one hand, improved the hardening capacity of refrigerative speed and workpiece, on the other hand because heating chamber also at the state that continues insulation, provides the energy for the production of second batch of workpiece.
Embodiment
This equipment mainly contains compositions such as double-walled water cooled furnace wall, intermediate door slide valve, heating chamber, cold house's feed mechanism, high pressure positive blower, interchanger, guiding device, vacuum system and electrical control system.When workpiece takes out immigration cold house quench zone by feed mechanism after the heating chamber heating, charge into rare gas element then, open the high pressure positive blower at top and force Cooling Quenching.Shifting out of workpiece do not need whole heating chamber is cooled down so on the one hand, improved the hardening capacity of refrigerative speed and workpiece, on the other hand because heating chamber also at the state that continues insulation, provides the energy for the production of second batch of workpiece.
Claims (1)
1. high pressure gas quenching is formed one for heating chamber by two chambers, and another is the high pressure gas quenching chamber.Workpiece after the heating is fetched into the cold house by the feed mechanism of cold house and carries out high pressure gas quenching.
