Description
Technical field
The present invention relates to one kind being primarily adapted for use in large-scale hot isostatic press, improves the unbalanced method of hot-zone three phase supply,
Specifically, the present invention relates to a kind of methods for the reasonable setting heater element in hot isostatic press.
Background technology
Hot isostatic press be implement compacting and sintering equal pressing equipment, it be one kind in closed container with nitrogen or argon
Gas gas is transmission medium, and under the collective effect of high temperature and high pressure, compacting sintering processing is carried out to product.Large-scale hot isostatic pressing
Machine makes to reach in heating region required temperature by arranging heating element in stove inner region.Due under atmosphere, stove silk
By radiation and convection type to gas and structural member in the inner region of hot-zone（Including product）Deng progress heat exchange.Gas is heated swollen
Swollen density, which lightens to flow upward, forms thermal current convection current, this can form top and the bottom temperature difference in hot-zone, and in hot-zone, height is larger
When, top and the bottom temperature difference can bigger.And in the courses of work such as heating and thermal insulation, the heating power needed for mono- areas bottom Na is remote
Much larger than other each areas.To solve this problem, hot-zone can be divided into twoth area or more in short transverse according to hot-zone height difference
Heating element is respectively set per area in multi-region, and it is almost the same to be finally reached temperature in hot-zone for independent heating temperature control.
Setting electrode can be drawn since the extraction of electrode needs to meet the requirements such as insulation and sealing in hot isostatic press simultaneously
The influence of very important intensity is caused at the position for going out device, and number of electrodes setting is more, and intensity of pressure part is subject at this
It slackens bigger.Therefore to the introducing of electrode, it is necessary to take quantity few as possible as possible.Existing hot isostatic press generally use is single-phase
Electrode and stove silk is arranged in the mode of load, and two electrodes are only arranged in the areas Ji Ge, and electrode and corresponding stove silk form simplest electricity
Air circuit.For dividing the large-scale hot isostatic press in 4th area, then 8 electrodes need to be set altogether.It is most lower in practical heating process
The stove silk in area and the heating power in remaining each area have sizable difference, and which results in the threephase load of power supply grid is seriously uneven
Weighing apparatus.
Under the increasing situation of current HIP products, hot isostatic press to enlarged development trend be inevitable, big
The mismatched degree of the areas type hot isostatic press Zhong Ge stove silk heating power is increasing, exceeds the adjusting of power supply grid itself gradually
Limit of power.The influence of power supply quality etc. caused by the serious imbalance of threephase load, except the prodigious efficiency for affecting power grid
Outside, and in turn harmful effect is caused to equipment itself, or even directly influences the performance of all appliance components and uses the longevity
Life.There is a kind of structure in the prior art, bottommost heating elements are separately set below the table top for placing product.With regard to current use
From the point of view of situation, to the threephase load non-equilibrium state of power grid, there is no direct improvement results.
Invention content
The purpose of the present invention is place in view of the shortcomings of the prior art, providing a kind of electrode, to introduce quantity few, can
Eliminate the spread of voltage that brings of the serious energy imbalance of hot isostatic press threephase load, efficiency reduces, equipment from gas-distributing motor and
The various harmful effects such as the service life reduction of component, during hot isostatic press heating element generating heat can be improved, power supply efficiency and
The method of quality.
The above-mentioned purpose of the present invention can be by being reached with lower structure.Hot-zone three in a kind of large-scale hot isostatic press of improvement
It mutually powers unbalanced method, it is characterised in that include the following steps：
In the pressure vessel 6 of hot isostatic press, by superposed heat screen 2 and positioned at 3 shapes of heat insulating mattress of bottom
At hot-zone space heating element 4 is set on the periphery in each height hot-zone space by being highly divided into multiple hot-zones；It will be most lower
Heating element 4 is set as by delta connection in the hot-zone of height, and three identical loads being connected with three electrodes, three identical
Load Balanced is distributed in the periphery for most descending height hot-zone；The heating element 4 of remaining each height hot-zone is arranged to each connection one
The single load of electrode, and another electrode is shared, each electrode is drawn by the electrode pulling device 5 of 6 lower section of pressure vessel
Outside pressure vessel 6, the electrode outside pressure vessel is drawn by three phase-change pressures and controller 7 and three sets of single-phase transformations and controller 6,
To each independent temperature control of height hot zone temperature in hot-zone and adjust output power.Outside pressure vessel correspondence is connected to by corresponding connection
Have voltage control electrical system, then access three-phase five-wire mode power supply system in.
The present invention has the advantages that compared with the prior art.
The present invention is in the pressure vessel 6 of hot isostatic press, by superposed heat screen 2 and positioned at the heat insulating mattress of bottom
3 are formed by hot-zone space, and by multiple hot-zones are highly divided into, heating element 4 is respectively set on the periphery in each height hot-zone space；
It sets by delta connection the hot-zone heating element 4 for most descending height to, three identical loads being connected with three electrodes, three
Identical load is distributed in the periphery for most descending height hot-zone；The heating element 4 of remaining each height hot-zone is arranged to each connection one
The single load of electrode, and another electrode is shared, each electrode is drawn by the electrode pulling device 5 of 6 lower section of pressure vessel
Outside pressure vessel 6；This structure is answered on the spatial altitude of hot-zone in the large-scale hot isostatic press of point hot-zone of three or more
With having the advantages that, first can be arranged electrode pulling device quantity few as possible, reduce to each component of pressure vessel
Intensity slackens degree, ensures that all structural members of the pressure vessel under hyperpressure are safe and reliable, second may be implemented each height
Area's heater element independence temperature control is spent, third makes the three phase supply of hot-zone reach state in a basic balance, and it is uneven to eliminate severe three-phase
The spread of voltage brought, efficiency reduce, and equipment is from the various harmful effects such as the service life reduction of gas-distributing motor and component.
