The detail drawing of the embodiment of the annealing device that the present invention relates to sees figures.1.and.2 and elaborates.The heater body total length is 0.8-1.2m, and as shown in Figure 1, the annealing device 3 of present embodiment is divided into heater body and calandria (in the present embodiment, being sheathed heater) two parts at length direction.In addition, also can use sheathed heater device in addition, for example also can be made as baffle heater as calandria.
That is, heater body constitutes by be divided into two-part heating plate 11 and 21 at length direction, heats the sheathed heater 12,22 of these heating plates 11,21 and is located in the heating plate 11,21.And, the 13, the 23rd, be located at the temperature sensor in the heating plate 11,21.Being divided into two-part calandria (sheathed heater) 12,22 can be heated to and surpass 250 ℃ temperature.These condition enactments are by there not being illustrated controller to carry out.
And the outside of heating plate 11,21 is by insulation material 31 insulations, at its arranged outside stay-warm case 32.
As shown in Figure 2, heating plate 11,21 cuts off with the plane vertical with the silk road, is formed on the inboard of heating plate 11,21 so for groove 11a, the 21a that strand Y is moved, and imbeds sheathed heater 12,22 as mentioned above.
In this embodiment, in groove 11a, the 21a, be equipped with thread guide mechanism 14,24 in the moving direction compartment of terrain of strand Y.
At this, the weight containing ratio that the material of the heating plate 11,21 that the present invention relates to adopts copper more than 60%, the weight containing ratio of aluminium is at the copper alloy more than 3%, its coefficient of heat conduction is made as for example more than 0.1cal/cms ℃, functional, especially as the composition of heating plate preferably the weight containing ratio of copper be that the weight containing ratio of 60-70%, aluminium is that the weight containing ratio of the copper alloy of 3-6% or copper is that the weight containing ratio of 85-90%, aluminium is the copper alloy of 8-11%.
Below, according to the experimental result that the present inventor carried out, the copper alloy of weight containing ratio more than 3% of the weight containing ratio that the material that specifies the heating plate 11,21 that will the present invention relates to is made as copper more than 60%, aluminium, especially be preferably copper weight containing ratio 60-70%, aluminium weight containing ratio 3-6% or the copper alloy of weight containing ratio 8-11% of weight containing ratio 85-90%, aluminium.
(1) about the even heating of heating plate
As shown in Figure 1, the heating plate 11,21 of the high-temperature heating equipment that the present invention relates to extends along the mobile route of strand, as shown in Figure 2, form groove 11a, the 21a that has a road on its surface, by sheathed heater 12, the 22 heating heating plates 11,21 that extend in heating plate at length direction along this road.
During heating plate 11,21 heating, usually (promptly at the point midway of the length direction of heating plate (Fig. 1 about), the centre position of heater length direction), measure the temperature of the bottom of above-mentioned groove 11a, 21a that strands move by temperature sensor 13,23, temperature of heating plate is controlled at the temperature of setting.At this moment design temperature is at the 1st heater of false twist processing machine, is chosen to be for example 220 ℃ of such design temperatures in the strand temperature of heater outlet portion.
In the non-contact type high-temperature heating equipment that the present invention relates to, when the temperature of heating plate was set at institute's fixed temperature (for example 500 ℃), the Temperature Distribution of heating plate length direction (temperature of the bottom of the above-mentioned groove that the mensuration strand moves) as shown in Figure 4.In Fig. 4, dotted line is represented to make the heating plate occasion with brass, and chain-dotted line is represented the occasion with the stainless steel making.
Heater has opening up and down length (up and down) direction, so by heat releases from here such as convection current, thereby the temperature of heating plate of the upper-lower position of Fig. 4 is lower than central portion temperature.And if improve design temperature, the standard deviation of Temperature Distribution increases.
The present inventor thinks that the temperature distribution state of the heating plate that the brass that is represented by dotted lines is made is because the difference of the coefficient of heat conduction of heating plate material causes with the difference of the temperature distribution state of the heating plate of the stainless steel making of representing with chain-dotted line.
The coefficient of heat conduction of brass is 0.26cal/cms ℃, the stainless coefficient of heat conduction is 0.03cal/cms ℃, the stainless coefficient of heat conduction is littler than brass, be about 1/10, therefore, during as heating plate, shown in Fig. 4 chain-dotted line, the Temperature Distribution of the length direction of heater is very uneven with stainless steel.
This heater is a high temperature heater (HTH), for the strand fusion in the short time that is melted on the thread guide mechanism being removed so that can wear silk when the fracture of wire, must make heating plate all be heated to sufficient high temperature (for example more than 320 ℃, best more than 400 ℃), promptly, must improve the design temperature of heating plate, so, the design temperature of heating plate with become big as its temperature difference of sheathed heater of thermal source of heating.
In addition, at this moment, be made as institute's fixed temperature, must improve the design temperature of heating plate in order to make strand temperature in heater outlet portion, same, the design temperature of heating plate with become big as its temperature difference of sheathed heater of thermal source of heating.
Like this, for heating plate is heated to temperature desired, make sheathed heater be heated to very high temperature, so there is the problem of its lifetime.In addition, because strand moves in the heater that temperature distributing disproportionation is spared, worry and to produce bad influence to silk quality.Therefore, had better not use the heating plate of stainless steel as high-temperature heating equipment.
On the one hand, by Fig. 4 dotted line as can be known, with the brass of the coefficient of heat conduction big (0.26cal/cms ℃) during as heating plate, becoming on the even question essence of temperature distributing disproportionation has not existed.According to present inventor's research, the stainless coefficient of heat conduction is about 1/10 of brass, so the problems referred to above are arranged, if having the coefficient of heat conduction of 1/4-1/3 degree of the coefficient of heat conduction of brass, the heterogeneity problem of Temperature Distribution can produce hardly so.According to present inventor's experience, the coefficient of heat conduction is preferably more than 0.10cal/cms ℃.
(2) about the corrosion resistance of heating plate
, according to present inventor's research, if make heating plate with brass, as previously mentioned, the deterioration during heat is remarkable, and special when being warmed up to more than 400 ℃, corrosion is remarkable, and the such high temperature heater (HTH) of the present invention can not use.
Especially, be generally and make treatment process in good condition, often give filements of synthetic fibres finish (oil), when the strand that is given this finish is heated to high temperature as mentioned above, finish evaporation, decomposition in heater (heater).Because the finish and the high temperature of this evaporation, decomposition, heater material is perishable, and as countermeasure, material must be selected for use can oil-proof composition and resistant to elevated temperatures.
As countermeasure, the present inventor adds aluminium (Al) in copper alloy, be conceived to improve its corrosivity, and the copper alloy of studying various aluminium containing ratios is made the adaptability of the heating plate of high-temperature heating equipment (coefficient of heat conduction and for corrosion resistance of finish etc.).
Figure 941011003_IMG2
In table 1, a part (test portion A-H) and the result of study (coefficient of heat conduction, weight rate etc.) thereof of each Albatra metal-of expression research.
At this, the weight rate of table 1 is tried to achieve by following method.Test portion is soaked about 10 seconds in the treatment oil solution stoste of exemplary synthetic fibers polyester strand, remain on subsequently in 560 ℃ the gas medium (soaking burning), carried out handling for 36 times repeatedly in 200 hours, test portion weight is made as W before handling, and the weight after the above-mentioned processing is made as W 1, the changes in weight (W before and after handling 1-W 0) absolute value with handle before weight W 0The percentage [100 * (W of ratio 1-W 0)/W 0] as weight rate.Weight rate becomes the judge index of corrosion resistance, we can say, the more little corrosion resistance of weight rate is good more.
In the represented experimental result of table 1, test portion A is that the aluminium containing ratio in the copper alloy is 0, and its weight rate (* 1 of table 1) is very big as previously described, owing to do not measure, omits.In addition, in table 1, it is 16 times that the soaking separately of test portion D, F, G burnt number of times, changes in weight state and test portion E, H do not have big difference therebetween, test so test portion D, F, G have ended the burning of soaking after this, therefore, their weight rate does not have record (* 2 of table 1)., can think, even it is these test portions D, F, G are used as the heating plate of the heater of filements of synthetic fibres, also no problem.And copper alloy fusing point height so be used for heating plate 400-800 ℃ of use, can not have problems.
Result of the test shown in the table 1, in the copper alloy containing ratio of aluminium to the influence of resistance to oxidation, corrosion resistance and Temperature Distribution (heat transfer coefficient) if be expressed as curve map, then as shown in Figure 5.Can understand from Fig. 5, be copper alloy made heating plate more than 3% by the weight containing ratio by aluminium, and resistance to oxidation, good corrosion resistance, the good heater of Temperature Distribution can be provided.And, consider that from the even heating of the heating plate of heater the addition of aluminium is below 11%, preferably discontented 8%, like this, the coefficient of heat conduction can reach desirable 0.1cal/cms ℃.But, when paying the utmost attention to corrosion resistance, even 0.07cal/cms ℃ of degree also may be used.
The Temperature Distribution of the heating plate of making of the test portion C of table 1 is illustrated in Fig. 4 with solid line.Can understand that from the solid line of Fig. 4 the Temperature Distribution of the heating plate of making of test portion C is approaching with the heating plate of making of brass, and, can understand that by table 1 and Fig. 5 the heating plate weight rate of making of test portion C is little, corrosion resistance is also good.
(3) about the extrusion molding of heater
The heating plate of the high-temperature heating equipment that the present invention relates to extends along the mobile route of strand, forms the length direction groove that has a road on its surface, therefore, and during fabrication by the extrusion molding manufacturing.
With regard to above-mentioned A-H test portion research extrusion molding, obtain the result of table 1 record.That is, the aluminium addition is above being difficult to extrusion molding in 6%, discontented 8% the scope.Therefore, the balance that finds the formability of aluminium addition and heating plate is important, as shown in the present, is that copper alloy more than 60% is as the basis with the weight containing ratio of copper, the addition that it is desirable to aluminium is preferably 3-6% or 8-11% as being calculated as more than 3% with the weight containing ratio.
Make the heating plate of heater shown in Figure 1 of the material of above-mentioned test portion C, this heater is installed on the draw texturing machine shown in Figure 3, the temperature of the heating plate 11 of upside is set at 550 ℃, and, the temperature of downside heating plate 21 is set at 255 ℃, the polyester strand (POY) of 125De/36f is stretched with extensibility 1.78, simultaneously, invest turn by three multi-plate false-twisting devices, to carry out heat fixation along the turn that strand chases after by above-mentioned heater, and divide process velocity to be wound in the package, like this with 1000m/, false twisting processing operational test was gone through six months, in resistance to oxidation, on corrosion resistance and the yarn quality without any problem.
According to the present invention, can solve the corrosion resistance problem of heating plate of the high temperatureization of the heater of following filements of synthetic fibres, make the copper alloy composition contain aluminium, improve corrosion resistance for the finish of evaporation, decomposition in the heater., exist because the amount of aluminium makes the problem of the extrusion molding difficulty of heating plate.Therefore, the balance that finds the formability of aluminium addition and heating plate is important, according to the present invention, with the weight containing ratio of copper is that copper alloy more than 60% is as matrix, the addition of aluminium is calculated as more than 3% with the weight containing ratio, is preferably 3-6% or 8-11%, can reach the present invention.And, if the addition of aluminium is below 3%, the corrosion resistance problem is arranged, in addition, the addition of aluminium is surpassing 6%, then is being difficult to extrusion molding in discontented 8% scope, so the addition of suggestion aluminium is preferably got above-mentioned scope.
Furtherly, from the homogeneous heating aspect of the heating plate of heater, the addition that it is desirable to make aluminium is below 11%, and is preferably discontented 8%, and the coefficient of heat conduction becomes 0.1cal/cms ℃ like that.But, when paying the utmost attention to corrosion resistance, even also can use for 0.07cal/cms ℃ of degree.
