Description
Technical field
The utility model relates to high vacuum shrend solid solution furnace system, especially relevant with the structure of the high vacuum shrend solid solution furnace system that can improve vacuum tightness in treating processes.
Background technology
The feature that titanium alloy is little with proportion, intensity is high, is used widely in aircraft industry and part civil area.After the machine-shaping of titanium alloy component, high strength be reached, must solution treatment be carried out.Other specific alloy material, for obtaining required metallographic structure, or reaches the uniform effect of alloying constituent, to ensure the design performance of part, also needs to carry out solution treatment.Solution treatment is temperature alloy being heated to more than solid-state phase changes point, the thermal treatment process then cooled rapidly.The solution treatment of alloy material has 3 main points: 1, need to heat under high vacuum state, because occur that the oxygen level of oxidation or trace will cause the obvious decline of alloy property; 2, will have the speed of cooling be exceedingly fast, the type of cooling the fastest in conventional processing is water-cooled; 3, part is transferred to the time tank and is wanted fast from hot-zone, and the long time can cause Part temperature to decline, and local is temperature required lower than solid solution, then do not reach expection treatment effect.
Adopt the vacuum heat treatment furnace of all-metal heat insulation screen, the high vacuum unit of configure band diffusion pump, the requirement of heating under can meeting titanium alloy high vacuum.But the air cooling that vacuum heat treatment often adopts, the mode of oil cooling, be difficult to meet the needs of alloy material solution treatment to speed of cooling, and water-cooled is the optimal type of cooling of alloy material solution treatment.But water saturation vapour pressure is higher, as easy as rolling off a log vaporization, cannot obtain high vacuum under having the environment of water, and this is the most basic difficult point place of vacuum water quenching solid solution furnace.
Fig. 1 shows the vacuum water quenching solid solution furnace 1 that this field at present adopts, and it adopts vacuum dual-chamber oil quenching furnace to convert substantially, changes the quenching oil in oil groove into water.As shown in Figure 1, the side of vacuum water quenching solid solution furnace 1 is heating chamber 11, and opposite side is cooling room 12, and centre is separated by salable and heat insulation slide valve 13, is cooling trough 121 bottom cooling room 12.After heating under the high vacuum environment of workpiece 14 in heating chamber 11, open middle gate plate valve 13, utilize transshipment acitivity 15 workpiece 14 to be transported to the top of cooling room 12 cooling trough 121 from heating chamber 11, after closing middle gate plate valve 13, workpiece 14 is sunk to cooling trough 121 and cools.This equipment, owing to not solving the problem of finding time under water environment, in workpiece 14 transport process, cannot make the vacuum state that cooling room 12 reaches high, so there is the problem that much cannot overcome.
1, cooling room 12 is interior because there is water to exist, and can only obtain the vacuum tightness of 8000Pa (pounds per square inch absolute (psia)) left and right.This vacuum tightness, concerning hot most of alloy materials, is to cause highly oxidized.Because the vacuum tightness of most of workpiece needed in heat-processed is 10-2 ~ 10-3Pa level, compare the vacuum tightness of kPa level, there is the difference of 5 ~ 6 orders of magnitude, so the vacuum tightness of cooling room about 8000Pa is for workpiece process, is wretched insufficiency.
When 2, changing of workpieces being transported to cooling room 12 from heating chamber 11, need first the slide valve 13 of centre to be opened.When slide valve 13 is opened, a large amount of oxidizing gas (air and steam) remaining in cooling room 12 will enter the heating chamber 11 of high temperature (about 1000 DEG C), and the heating unit in heating chamber 11 and lagging material will by severe oxidations.This can cause the transition loss of components and parts in heating chamber 11, and in the extreme influence life-span of heating unit and heat insulating element, cause heating chamber 11 replacement cycle extremely short, the running cost of equipment is very high.
3, lost by the metallic insulation screen that is repeatedly oxidized and heating unit luminance brightness in heating chamber 11, the gas of surface adsorption is more, can affect pump-down performance during post-processed, and the vacuum index of equipment is by fast degradation.In real work, ensure that workpiece 14 processes required vacuum index with regard to needing the pumpdown time more grown, or reduce index use, this will cause production efficiency of equipment degradation or process workpiece 14 quality to decline.
4, be responsible for the vacuum pump set that cooling room 12 is found time, owing to extracting a large amount of steam out, after these steam enter pump chamber, meeting liquefy again, after mixing with vacuum pump oil, makes vacuum pump oil lose efficacy.The lost efficacy result that causes of vacuum pump oil is that the pump-down performance of vacuum pump sharply declines, and the rotor wear of vacuum pump, damages even soon.
The employing that current equipment has, when opening middle gate plate valve 13, is filled with the way of high pure nitrogen to heating chamber 11, alleviate these problems, but effect not obvious.Because the oxidizing gas of cooling room 12 remnants is too many, workpiece 14 must enter into again in cooling room 12, and the help therefore for workpiece 14 oxidation is little.In addition, middle gate plate valve 13 opening is comparatively large, and the gas phase mutual diffusion between cooling room 12 and heating chamber 11 is not avoided, although the oxidation of high temperature components and parts can be alleviated to some extent in heating chamber 11, is only slightly improve yet.Usually the cycle of this kind equipment heating chamber 11 integral replacing can shorten to 1/10 of ordinary life.
In order to overcome the problems referred to above, the alloy part also had is produced and is taked another way, before part processing, directly inside conventional equipment, carries out solution treatment to starting material, is then processed into part.Adopt processing parts in this way, comparatively large to raw-material waste, the alloy material machining after process is also more difficult, and total manufacturing cost of part is very high.
In addition, conventional vacuum water quenching solid solution furnace 1, need---transshipment acitivity 15 enters heating chamber 11, and---transshipment acitivity 15 holds up workpiece 14, and---transshipment acitivity 15 exits heating chamber 11---closing slide valve 13---, and transshipment acitivity 15 be lowered into the several action of water through opening a sluice gate plate valve 13 when workpiece 14 is transferred to cooling trough 121 from heating chamber 11.From " transshipment acitivity 15 exits " action, until workpiece 14 enters water, these actions need to complete at short notice, and The faster the better.Because after workpiece 14 enters cooling room 12, temperature can sharply decline, and when the temperature of workpiece 14 drops to below transformation temperature, the effect of solution treatment is just greatly affected, particularly miniature parts.Current equipment can accomplish 8 ~ 10s execution, and this speed is inadequate concerning miniature parts.
Because vacuum water quenching solid solution furnace does not overcome the above problems, there is not vacuum water quenching solid solution furnace truly in the market.The equipment that users use is all simply utilize vacuum dual-chamber oil quenching furnace, and the oil in oil groove is changed into water to use.This device processes effect is bad, and failure rate is high, and the heating chamber life-span is short, and therefore, research and development high vacuum shrend solid solution furnace truly has very important meaning to industries such as aviation, military project, special materials.
