Abstract
A method of controlled quenching of light metal castings in a liquid bath has castings in the liquid bath subjected, from below, at least temporarily, by a rising flow of gas bubbles. The gas bubbles are generated in situ in a uniformly distributed way at the base of the liquid bath.
Description
The present invention relates to one and be used for the apparatus and method of controllably light metal casting being quenched at bath of liquid.Foundry goods quenched in bath of liquid will form a well-known heat treatment section of forming by ferrous metal and non-ferrous metal.Known form has foundry goods is immersed water-bath or oil bath and to the foundry goods trickle, foundry goods refrigerative method under air-flow also often used.By as different thermal conductivity and the free convection of the liquid of heat-eliminating medium or gas or force the mobile state, and the funtcional relationship of the heat conductivity of the thermal capacity of heat-eliminating medium and metal, can obtain different speed of cooling, this speed can form certain structure in the foundry goods of different wall.
By the 62-202019A Japanese Patent, a known device comprises a water storage container, the horizontally disposed pipeline of a ring-type can be housed on its edge and be used for draining.After gas is discharged, treat that footing immerses water storage container by e Foerderanlage from gas exhaust duct.
By No. 1574648 United States Patent (USP)s, a known device comprises: a retaining basin, portion's side-walls is provided with the terminal of gaseous tension pipeline within it, which is provided with injector, is used for forming the cooling flow that a bubble is strengthened.The part of waiting to quench is fixed in below the liquid level by a grip device.
Purpose of the present invention is by the improvement to device and method, makes the quench treatment easier realization that becomes.This purpose is finished by a method is provided, in the method: the foundry goods in bath of liquid is from the beneath effect that at least temporarily is subjected to rising bubble stream, wherein the bubble of bubble flow produces in the bath of liquid bottom, this is by providing one to comprise that the device in the pond of a full of liquid realizes, this device is provided with at least one liquid inlet and a liquid exit, be provided with a bubble generator in the bottom, pond, this device comprises at least that in the bottom, pond an air feed chamber, air feed chamber comprise that one has the lid of a plurality of production wells.For achieving this end, bubble is uniform distribution state ground generation in the bottom, pond.Preferably foundry goods is placed in the position that bubble produces top, zone certain distance.Described bath of liquid can be water-bath and the bubble flow that comprises air filled cavity.Yet foundry goods is immersed in the bath of liquid-when being heated to certain starting temperature in advance-and may cause the clod wash in the previous technology, can obviously reduce or increase speed of cooling according to the present invention by described bubble flow.Particularly, by setting and regulate the unlikely decline prematurely of certain transition temperature that bubble flow can guarantee the foundry goods tissue.The generation of bubble flow need be in whole quenching process, and on the contrary, producer can cut out before foundry goods is finally taken away from bath of liquid.
This creationary bubble generator can comprise at least one by an air feed chamber with sealing of lid of a plurality of production wells in pond bottom.Lid is made up of a porous plate, is used under the situation that has an overpressure in the air feed chamber bubble upwards being flowed with equally distributed form.Porous plate can be made by the metal foam of beginning to speak, porous stupalith or sintering metal.Also there is a kind of possibility, promptly uses the lid of wire mesh screen as the air feed chamber.Simultaneously, prevent to help air feed in any liquid inflow air feed chamber.Owing in the time of can't preventing fully, be necessary for liquid and in the air feed chamber, establish a leakage fluid dram.This air feed chamber should comprise the pressure control valve that is used for controlling or setting bubble flow.Whole air feed chamber also can be substituted by autonomous channel that has independent sprayer and conduit with a plurality of production wells at bottom of gullet.
Above the lid of air feed chamber, in liquid pool, should have weight tray to deposit foundry goods; Must be provided with relatively large through hole on the described weight tray with passage as bubble flow.
The liquid that is provided by inlet can flow along the pond internal recycle, and cooling again in this process.Also can be simply the liquid of spillage be discharged or it is utilized in other process.
Below in conjunction with an embodiment of accompanying drawing discussion apparatus of the present invention, wherein
Fig. 1 is the vertical cross-section diagram that fills up the pond of liquid;
Fig. 2 is the vertical view in pond as shown in Figure 1.
Fig. 1 illustrates a cuboidal pond 11, comprising: a top opening 12 and a bottom 15; The position of certain distance has a lid 13 that is used for sealing air feed chamber 14 above bottom 15.This lid 13 is formed by a porous flat plate that comprises a plurality of production wells.Lid 13 places on the chest profile 21, and the periphery of chest is placed on the bottom 15, is provided with a weight tray 22 that is used for carrying foundry goods on the position of certain distance above the lid 13.On lid 13, be full of in the tank 11 of quenching liquid 16, rising bubble 17 14 rises by porous lid 13 from the air feed chamber.Pond 11 comprises near a closable water outlet 19 opening 12 above the tank 11.For the work output that makes water in quenching process is fixed, above weight tray 22, be provided with a water inlet 24 and water outlet 25 in addition.Air feed chamber 14 is provided with a compressed air communication pipe 20.One water outlet 23 places the bottom in air feed chamber 14.
In Fig. 2, can see a pond 11 by overlooking, this pond 11 comprises the weight tray 22 of insertion and the inlet of establishing for hardening liquid 18,24 and exports 19,25 and communicating pipe 20 of establishing for pressurized air.The periphery of also appreciable cubes profile 21 in addition.
