Below, according to the experimental result that the present inventor carried out, specify the excellent results that obtains by the present invention.This experiment utilizes heating plate of the present invention and carries out, the wherein material of heating plate 11, the 21 weight containing ratio more than 60% that is made as copper, the copper alloy of weight containing ratio more than 3% of aluminium especially are preferably the copper alloy of weight containing ratio 8-11% of weight containing ratio 85-90%, the aluminium of the weight containing ratio 3-6% of weight containing ratio 60-70%, aluminium of copper or copper.
(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 has groove 11a, the 21a that extends along the mobile route of strand, as shown in Figure 2, form the silk 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 predetermined temperature.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 predetermined 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) was shown in the solid line among Fig. 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, thus 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 108.9J/ms ℃ (0.26cal/cms. a ℃), the stainless coefficient of heat conduction is 12.6J/ms ℃ (0.03cal/cms. a ℃), 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 predetermined 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 being heated to predetermined temperature, 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, when being used as heating plate with the brass of the big 108.9J/ms of the coefficient of heat conduction ℃ (0.26cal/cms. ℃), 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 and is equal to or greater than 41.9J/ms ℃ (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 the finish of ability evaporation, decomposition and resistant to elevated temperatures for use.
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.).Table 1

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 be (table 1
*1) is very big as previously described,, omits owing to do not measure.In addition, in table 1, it is 16 times that the soaking separately of test portion D, F, G burnt number of times, and changes in weight state and test portion E, H do not have big difference therebetween, so test portion D, F, G have ended soaking and burn test after this, therefore, their weight rate is not put down in writing (table 1
*2)., 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 good heater of extrusion molding, 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 41.9J/ms ℃ (0.1cal/cms. ℃).But, when paying the utmost attention to corrosion resistance, even also may use 29.3J/ms ℃ of (0.07cal/cms. ℃) degree.
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
