Description
METHOD FOR CONTROLLING VARIATIONS OF AL-TI-C ALLOY GRAIN
REFINEMENT ABILITY THROUGH CONTROLLING COMPRESSION RATIO
[0001] The present invention relates to processing techniques, especially relates to a method for controlling variations of Al(aluminum)-Ti(titanium)-C(carbon) alloy crystal grain refinement through controlling a ratio of sectional area of Al-Ti-C alloy before press processing to after press processing (namely compression ratio) during a production of the Al-Ti-C alloy.
GENERAL BACKGROUND
10002] Currently, Al-Ti-C alloy is much popularly employing in Al material machining as a most efficient preliminary alloy for Al and Al alloy coagulation crystal grain refinement. A refinement ability of the Al-Ti-C alloy crystal grain is a very important factor when judging a quality of Al processing material. Usually, the better the Al-Ti-C alloy crystal grain refinement ability is, the higher yield strength and the better malleability of the Al material are.
Therefore, the Al-Ti-C alloy manufacturers and research organizations are forward into developing improvements of the Al-Ti-C alloy crystal grain refinement ability. The US aluminum association has specially ruled an AA value to represent the crystal grain refinement ability. The AA value is a value that can be used for measuring the Al-Ti-C alloy crystal grain refinement ability, and the lesser the AA value is, the better the refinement ability of the Al-Ti-C alloy is. That is, the lesser AA value that the Al-Ti-C alloy added during Al and Al alloy producing process has, the more refined the crystal grain of the Al and Al alloy are.
With a development of the process and refinement technology, the AA value is decreased from 250 at very beginning to 170. Presently, alloy fabrication technology is focused on material components, melting process, and such like. However, a quality control during a press process of the Al-Ti-C alloy has been ignored or indifferent to people. The press process includes mill rolling and cast extrusion machine extruding, and many believe that a ratio of the sectional area before press process to that after press process (defined as compression ratio), a variation of temperatures before and after press process, a line speed at exit, and a quantity of the standers have relations with the refinement ability of the Al-Ti-C alloy crystal grain, and there is no quantitative optimal control method for control the refinement ability of the Al-Ti-C alloy crystal grain through these respects including compression ratio.
[0003] What is needed, therefore, is a method for controlling variations of Al-Ti-C alloy crystal grain refinement ability through controlling a compression ratio of sectional area of Al-Ti-C alloy that can overcome the above-described deficiencies.
SUMMARY
[0004] It is an object of the present invention to provide a method for controlling variations of Al-Ti-C alloy crystal grain refinement ability through controlling a compression ratio of sectional area of Al-Ti-C alloy.
[0005] One exemplary embodiment of the present invention is a method for controlling variations of Al-Ti-C alloy crystal grain refinement ability through controlling a compression ratio of sectional area of Al-Ti-C alloy including: A. establishing a relationship between variations of refinement ability of Al-Ti-C alloy crystal grain and parameters of press process of the Al-Ti-C alloy; setting the parameters of press process and controlling the variation of the refinement ability of the Al-Ti-C alloy crystal grain through controlling a value of the compression ratio.

Table 1
[9914j There is an international standard for the Al-Ti-C alloy production that the final product of the Al-Ti-C alloy should have a diameter of 9.5mm, that is a sectional area of 70.8mm2. Contents of table 1 is part of experiments data conducted by continuous casting and tandem rolling machines using a method for controlling variations of Al-Ti-C alloy crystal grain refinement ability through controlling a compression ratio of sectional area of Al-Ti-C alloy according to an exemplary embodiment of the present invention. The continuous casting and tandem rolling machines includes a rolling mill 30 and a cooling module for Al-Ti-C alloy during a cooling press process. The cooling module includes a temperature sensor for detecting a temperature before the press process of the Al-Ti-C alloy and a temperature afler the press process of the Al-Ti-C alloy. The press process of the Al-Ti-C alloy is completed through a cooperation of two rollers 31 of the rolling mill 30, and the Al-Ti-C alloy maintains solid state before, aftei; and during the press process. During the press process, there are two points of temperatures that one point of the temperature is before the pressure being imposed and the other point of the temperature is after the pressure being released. Before the pressure being imposed, an instantaneous temperature of the Al-Ti-C alloy is about the same as an input temperature, and after the pressure being released, an instantaneous temperature of Al-Ti-C alloy is about the same as an output temperature, therefore it is convenient to detect temperatures of the two points.
[0015] Referring to FIG. 1, Al-Ti-C alloy melt is put into a crystallize wheel 20 from a crucible 10 thereby forming an Al-Ti-C alloy bar. Thereafter, the bar-shaped Al-Ti-C alloy is put into the rolling mill 30 to conduct press process. An amount of standers of the rolling mill 30 could be 3,4, 5, 6,7, 8,9 or 10. Tn the illustrated embodiment as shown in FIG. 1, an amount of standers of the rolling mill 30 is 10. Referring to FIG. 3, one stand of the rolling mill 30 is shown in enlarged view. The two rollers 31 of the rolling mill 30 are rolling inward and toward each other. S1 is denoted for the sectional area before press process, and S2 is denoted for the sectional area after the press process. There are at least two temperature sensors provided therein, which are configured to detect the temperature of the Al-Ti-C alloy before the press process and the temperature of the Al-Ti-C alloy after the press process. A scope of temperatures of the Al-Ti-C alloy before the press process is between 300°C-450°C.
The temperature of the Al-Ti-C alloy is raised when being processed in the rolling mill 30.
The cooling module is configured for spraying cooling fluid 50 onto the rollers 31 of the rolling mill 30. By controlling a flow rate of the cooling fluid 50, a temperature difference AT of the Al-Ti-C alloy before the press process and after the press process can be controlled within a proper range. In the illustrated embodiment, the cooling fluid 50 can be water.
The Al-Ti-C alloy comes out from the rolling mill 30 and forms an Al-Ti-C alloy rod.
[0016] From the data shown in table 1, the relation between the parameters of the press process and the refinement ability variation AAA can be conclude as the formula described below: AAA=K* D * V/ (AT * n) 100171 In the formula, AAA=AA1-AA2, wherein AA1 represents a refinement ability value of the Al-Ti-C alloy before the press process, AA2 represents a refinement ability value of the Al-Ti-C alloy after the press process. K is a constant and can be calculated according the data of table ito be 5.13. D represents the compression ratio, and D=51/52, S is denoted for the sectional area before press process, and S2 is denoted for the sectional area after the press process. AT represents a temperature variation of the Al-Ti-C alloy before the press process and after the press process. V represents a line speed of the outlet, and V=3AT6, V im/s. Currently the line speed V can reach high to 3OmIs. N represents the number of the standers of the rolling mill 30.
100181 The above-mentioned formula AAA=K D V/ (AT n) is applicable to both single stander and a plurality of standers, that is, whether the computation is for total standers or for single stander, the formula is applicable. When n=1, the computation means for the last one of the standers, and the sectional area of the Al-Ti-C alloy products output from the last stander is 70.8mm2.
[0019] In the production of the Al-Ti-c alloy, the press process parameters including temperature variation AT, line speed of the outlet V, and the amount of the standers are normally fixed, and through controlling on the compression ratio of the press process of the Al-Ti-C alloy, the refinement ability variation AAA can be controlled precisely. As shown in table 1, when AT=4°C, V=6mls, and n=8, by controlling the compression ratio D from 10.7 to 16.9, the refinement ability AAA can raised from 10.3 up to 16.3, and when the AA1 value maintains at 170, the AA2value can be changed from 160 to 154. s AT

K is a constant and can be calculated according the data of table ito be 5.13. D represents the compression ratio, and D=S1/S2, Si is denoted for the sectional area before press process, and S2 is denoted for the sectional area after the press process. AT represents a temperature variation of the Al-Ti-C alloy before the press process and after the press process. V represents a line speed of the outlet. N represents the number of the standers of the casting extrusion machine 40, and n=l.
[0025] The above-mentioned formula AAA=K D *V/ (AT n) is applicable to casting extrusion machine 40 with single stander. When n=l, the computation means for the last one of the standers, and the sectional area of the Al-Ti-C alloy products output from the last stander is 70.8mm2.
[0026] In the production of the Al-Ti-c alloy, the press process parameters including temperature variation AT, line speed of the outlet V, and the amount of the standers are normally fixed, and through controlling on the compression ratio of the press process of the Al-Ti-C alloy, the refinement ability variation AAA can be controlled precisely. As shown in table 2, when AT=150°C, V==4mIs, and nr=l, by controlling the compression ratio D from 10.7 to 19.8, the refinement ability AAA can raised from 1.5 to 2.7, and when the AA1 value maintains at 170, the AA2 value can be changed from 169 to 167.
[0027] The method for controlling variations of Al-Ti-C alloy ciystal grain refinement ability through controlling a compression ratio of sectional area of Al-Ti-C alloy has overcome the deficiencies of conventional technique for Al-Ti-C alloy process, and proved that variations of the refinement ability can be controlled through controlling a compression ratio of sectional area of Al-Ti-C alloy. By adopting the present invention, with the parameters of press process, the temperature variation before and after the press process, the line speed of outlet, and the amount of the standers being set fixed, the variations of the refinement ability of Al-Ti-C alloy crystal grain can be precisely controlled by controlling the compression ratio.
The greater the variation is, the better the refinement ability of Al-Ti-C alloy crystal grain is with a certain AA value before the press process and a lesser AA value after the press process.
[0028] It is to be understood, however, that even though numerous characteristics and advantages of exemplary and prefeffed embodiments have been set out in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the frill extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
