It knits and performance.Metal surface aluminising, can assign metal surface with excellent service performance, such as resistance to high temperature oxidation, corrosion-resistant, wear-resisting
Etc..
Aluminising metal has industrially been widely used as functional material and structural material.Such as electric appliance
The substitute material of silver used in all kinds of switches (Ag) base contact in industry, and draw as conductive elastomer and computer frames
Line etc..In addition, being carried out for the crystallizer etc. in air port, cinder notch and the steelmaking continuous casting machines in the blast furnace that manufactures fine copper
Deep layer aluminising can be improved its mechanical property and hardness and wear-resisting property and prolong the service life.Although aluminising metal is in work
Industry field has been widely used, but is but not yet applied in temperature measurement industry, especially in fixed point furnace, alternating temperature black matrix
In the thermal field uniformity debugging of furnace and stem body furnace etc., not using aluminising metal as the application method of equal heat block.
In one embodiment of the invention, aluminising metal (preferably aluminising red copper) is applied in temperature measurement device, to mention
For a kind of equal heat block comprising aluminising metal, this is the application mode of the special innovation of alumetizing process.It below will be with aluminising purple
It is described for the equal heat block of copper.
Aluminising red copper is to carry out the technique of aluminising working process on fine copper surface, and the method for aluminising mainly has solid process (such as
Powder investment, paste apply infiltration method etc.), liquid processes (such as hot dipping) and gas method.Fig. 1 is shown using in alumetizing process
Powder embeds the flow diagram of method preparation aluminising red copper.In the present embodiment, using the hot-dip aluminizing mode of powder investment,
The mixture of copper powder and alumina powder is handled prepared by red copper workpiece surface by way of hot-dip aluminizing.Such as Fig. 1
Shown, process flow may include：Oil removing S1 → derusting S2 → washing S3 → drying S4 → sealing S5 → shove charge S6 → heat temperature raising
S7 → heat preservation aluminising S8 → comes out and cools down S9.Wherein, S1-S4 is preprocessing process.Specifically, firstly, red copper workpiece is impregnated
Certain time carries out oil removal treatment (step S1) in degreaser, removes the oily matter of red copper workpiece surface.Then, by the work
Part is immersed in rust removing solution, removes the oxide layer (step S2) of red copper workpiece surface.Then, technique is washed with water and removes red copper workpiece
The residue (step S3) on surface, and (step S4) is dried and dehydrated.Next, including will be comprising copper powder and alumina powder
Powdered aluminizing medium (such as also contain activator NH4Cl) in aluminising case and (step is put into heating furnace with red copper Work piece sealing
S5-S6)；Heat temperature raising is then carried out under certain vacuum condition, until reaching required aluminising temperature (such as 800 degrees Celsius)
(step S7).Then, kept for the predetermined time at a temperature of aluminising (such as 6 hours, the time is merely illustrative, however it is not limited to this), into
Row heat preservation aluminising.Aluminising temperature is generally 700 DEG C -900 DEG C, and but it is not limited to this.Aluminising temperature is higher, and aluminising speed is faster.
But the excessively high matrix grain that will lead to of temperature is coarse, declines material property.Aluminising temperature and time increases, and the thickness of aluminized coating increases
Add.After keeping the temperature the aluminising predetermined time, cooling can be carried out and the workpiece after aluminising is taken out into (step S9) from aluminizing furnace, unpack and go forward side by side
Aluminising red copper finished product can be obtained after the cleaning shaping of row workpiece.The step of foregoing description, is merely illustrative, can also include it is more or
Less step, such as annealing steps can also be increased after keeping the temperature aluminising, since powder investment is mature aluminizing technology,
It is not described in detail technical process herein.
Aluminising red copper can also be prepared with other alumetizing process, such as liquid hot dipping, gas method.Wherein liquid hot dipping
It is that pure copper material is directly immersed in liquid aluminizing medium (can wherein to contain NH4Cl activator) in, the process shorter time is formed
Alloy layer.Being formed by coating at this time is adhesive layer rather than diffusion layer, thus in conjunction with parent metal loosely.This feelings
Also to heat generally after hot dipping under condition spreads coating soft heat, to form alloy-layer.This method advantage is that equipment is simply also easily grasped
Make, production efficiency is also high.Aluminising red copper can be 200-250 DEG C higher than the temperature that general fine copper uses, and has good heat resistance
Can, the Al of Dispersed precipitate in Cu2O3There is pinning effect to crystal boundary, dislocation motion can be hindered, to enhance matrix and improve copper
Recrystallization temperature, so Cu-Al2O3With high-intensitive and elevated temperature strength, the samming demand under hot conditions can satisfy.
The technical process of other aluminizing methods preparation aluminising red copper is repeated no more, but is similarly used for the present invention.
The aluminising copper tube that red copper surface aluminising is formed, it is smaller on the influence of the heating conduction of red copper, i.e., still have excellent
Heating conduction.In addition, alumetizing process can not only be efficiently modified the characteristic resistant to high temperature of base material (fine copper), additionally it is possible to improve female
The antioxygenic property of material.Therefore, aluminising red copper can effectively improve the inoxidizability of red copper, heat-resisting quantity.The fine copper of non-refractory
Workpiece can obtain pellumina after aluminising is handled, to make performance of the workpiece with high-temperature oxidation resistant, even if in sky
Also there is very high thermal stability in gas, sulfur dioxide gas and other media, thus becomes heat-resisting excellent material.For solid
Furnace for reproduction of fixed points, fixed point need the common metal material under high-temperature heating state, high-temperature condition for a long time during temperature correction
Material is particularly easy to be oxidized, and aluminising red copper pipe surface is the Al that high-temperature process is crossed2O3Film, structure even compact can be effective
Copper substrate is protected, the higher oxidation resistance temperature the more significant.
In addition, there is aluminising copper tube the ability for resisting arc erosion can directly contact with heater strip, it will not be because of electric arc
Fine copper inside attack.And internal oxidition generates Cu-Al after red copper aluminising2O3Al in alloy-layer2O3Particle even dispersion point
Cloth can bear load and prevent the plastic deformation of matrix on copper-based, to reduce matrix copper and friction pair in abrasion
Antithesis adhesion strength, improve wear resistance.This good characteristic is that aluminising red copper is debugged applied to fixed point furnace body thermal field again
In provide a favorable security.
Aluminising red copper is applied to the equal thermal technology of temperature measurement device by the excellent properties as above based on aluminising red copper, the present invention
(using aluminising red copper as equal heat block), to improve the furnace temperature of the temperature metering devices such as fixed point furnace, alternating temperature blackbody furnace and stem body furnace
Stability and realize thermal field more evenly.
Fig. 2 is the schematic diagram according to the fixed point furnace with the equal heat block of aluminising red copper in the embodiment of the present invention.This is fixed
Point furnace is to provide the heating furnace of heat source for fixed point crucible.As shown in Fig. 2, the fixed point furnace uses horizontal type structure, and use
Aluminium silicate salt with good thermal insulation property is as outer heat insulation layer material, that is, aluminium silicate salt thermal insulation material 101, to reduce the external world
The heat exchange frequency of environment and furnace interior.Inner-wall material in the fixed point furnace other than placing the position of crucible still can be used
The ceramic tube 102 of aluminium oxide, and the inner-wall material at the position for placing crucible uses aluminising red copper, it is preferably purple using aluminising
Copper pipe 103.That is, the equal heat block of aluminising red copper is placed in fixed point furnace in the present invention, it is preferably located in the correspondence of fixed point furnace
The inner wall of specific thermal field zone position (the uniform temperature field zone position 104 as where crucible).It is whole in crucible melting process of setting
Need heating temperature identical, and crucible itself has certain length, from crucible during metal molten, solidification in crucible
Front end is no more than 1 DEG C apart from the temperature difference to rear end for best thermal field effect.If temperature difference is larger, the metal in crucible be will be unable to
Realize the synchronous process melted, synchronize solidification.The data of collected freezing point will lose effective scientific basis, it will influence
The accuracy of temperature correction.Ceramic tube 102 has good heat-resisting quantity, but its heating conduction is far away from aluminising copper tube
Therefore 103 thermal coefficient affects the accuracy of fixed point reproduction to a certain extent.In general, used temperature-compensating can adjust
Whole thermal field effect, but consuming time is long for temperature-compensating adjustment process, affects the temperature measurement of entire fixed point furnace.And due to

Significantly.Although tradition Al2O3Ceramic tube unprotect gas can also work under 800 degrees Celsius of high-temperature condition, but its thermal conductivity
Can be poor, equal thermal effect is poor, and compactness is also relatively poor, and performance can not be comparable with aluminising red copper.
There is aluminising copper tube the ability for resisting arc erosion can directly contact with heater strip, will not invade because of arcing
Lose internal fine copper.And the Al2O3 particle even dispersion that internal oxidition generates in Cu-Al2O3 alloy-layer after red copper aluminising is distributed in copper
On base, load can be born and prevent the plastic deformation of matrix, to reduce the antithesis of matrix copper and friction pair in abrasion
Adhesion strength improves wear resistance.
