Abstract
The present invention belongs to the field of heat treatment of metal material. The cooling apparatus of the present invention includes flow equalizing body for cooling medium, cooling container, high pressure gas nozzle, water fog nozzle, heat exchanger, exhauster, forced convection blower and safety valve. There are forced convection blower set in the upper part of the cooling container, heat exchanger below the forced convection blower, cooling medium flow equalizing body below the forced convection blower and the heat exchanger, high pressure gas nozzle and water fog nozzle between the cooling medium flow equalizing body and the cooling container, and exhauster and safety valve on the casing of the cooling container. The present invention makes it possible to adjust the cooling strength between that of water cooling and that of static air, and has raised cooling capacity and lower cost compared with high pressure gas quenching.
Description
Technical field
What the present invention relates to is a kind of quenching refrigerating device, and particularly a kind of aerosol pump circulation high pressure gas quenching cooling apparatus that is used for the workpiece that heats under vacuum or protective atmosphere belongs to the metal heat treatmet field.
Background technology
For tissue and the performance that obtains to be scheduled to, method of cooling and equipment many routines, special and combination are used.High pressure gas quenching is exactly adopted two kinds of different quenching and cooling methods with fog quenching.The former shortcoming is: 1) the quench cooled ability is lower, only between gas at rest and salt bath (550 ℃) quench cooled ability, even adopt the helium of 20bar also to be difficult to reach the cooling power of working as with oil phase, therefore, require to be had high hardening capacity (having increased material cost) and less sectional dimension by the quenching part; 2) need to consume a large amount of high-purity gas and the required electric power (higher running cost) of blower fan stirring in the quenching process.The latter's shortcoming is that the directivity of spraying is stronger, and cooling uniformity is had certain influence.
In order to improve the cooling power of heating under vacuum high pressure gas quenching, generally adopt gaseous tension and the higher helium of price that improves when quenching at present.Find by literature search, Yan Chengpei chief editor's " vacuum heat treatment process and equipment ", China Machine Press, Beijing 1998.10, P246, introduced the cooling system structure of high-pressure gas quenching furnace, comprise: cooling vessel, the heat-eliminating medium equal fluid that flows, heat exchanger, with the forced convection blower fan, the forced convection blower fan is installed in cooling vessel top or side, the fan blade of forced convection blower fan is in the inside cavity of cooling vessel, the motor of forced convection blower fan is in the cavity outside of cooling vessel, in the inside cavity of cooling vessel the heat-eliminating medium that the has gas channel equal fluid that flows is installed, between the mobile equal fluid of fan blade and heat-eliminating medium of forced convection blower fan, heat exchanger is installed.
Summary of the invention
The present invention is directed to existing high pressure gas quenching exists quenching intensity deficiency and fog quenching to have the not good problem of uniform quenching, a kind of aerosol pump circulation high pressure gas quenching cooling apparatus is provided, make it improve quench cooled intensity and refrigerative homogeneity greatly, and cooling intensity can in very large range be regulated (between the cooling power of water and still air), the characteristics of have simultaneously that production cost is low, pollution-free, production process safety and suitable large-size workpiece quenching.
The present invention is achieved by the following technical solutions, the present invention includes: the heat-eliminating medium equal fluid that flows, cooling vessel, spraying nozzle, the high pressure gas nozzle, heat exchanger, the safety discharging air valve, exhaust blower and forced convection blower fan, its mode of connection is: on the top of cooling vessel the forced convection blower fan is set, bottom at the forced convection blower fan is provided with heat exchanger, the mobile equal fluid of heat-eliminating medium is set in the bottom of forced convection blower fan and heat exchanger, between mobile equal fluid of heat-eliminating medium and cooling vessel, spraying nozzle and high pressure gas nozzle are set, safety discharging air valve and exhaust blower are set on cooling vessel.The present invention can be vertical form, also can be the inverted form of the horizontal form of whole half-twist, whole Rotate 180 ° or the form of whole rotation unspecified angle.
During use, adopt the aerosol mixture as medium, the workpiece transfer that will heat in process furnace is to being provided with spraying nozzle, the high pressure gas nozzle, heat exchanger, the safety discharging air valve, in the cooling vessel of exhaust blower and forced convection blower fan, in cooling vessel, feed the gas of certain pressure then and spray into water smoke, gas and water smoke mix mutually directly under the driving of brute force stirring blower fan or spray to the quenching part by the mobile equal fluid of heat-eliminating medium, the heat that gas and water smoke absorb from the quenching part is taken away or is discharged cooling vessel by exhaust blower by being arranged on wherein heat exchanger again, thereby realizes the quick cooling purpose of quenching part.Feed gas in the cooling vessel and can be a kind of in the gases such as air, nitrogen, helium.
The present invention has substantive distinguishing features and marked improvement, quench with conventional high-tension gas and to compare with fog quenching, owing to adopted the aerosol mixture as medium, broken away from the limitation that improves constantly quenching gas pressure at present in order to improve vacuum high pressure gas quenching apparatus cools ability, for the expansion of quenching technique provides a new way; The cost of equipment is all obviously descended; Be applicable to the quenching requirement of different steel grades and different parts, and can and avoid aspect the cracking positive effect being arranged in the control distortion.
