れた。U.S. Pat. No. 3,613,767 describes an improved method for continuous casting and rolling of aluminum alloys such as 6201. The invention of this U.S. patent consists of a method for continuously forming VI rods of aluminum alloy such as 6201 without reheating the VI rods or the rough wires during the process. The cast rod that comes out of the continuous U-making machine passes through a rolling mill and a cold W pipe, during which it is continuously cooled. The heat of the cast bar exiting the continuous casting roll is not cooled and is maintained at a temperature within the solution temperature range as the cast bar enters the rolling mill. The cast bar is hot-processed in the rolling mill and immediately quenched upon exiting the rolling mill. , shorter than the time required for alloying component metals to precipitate at the grain boundaries of the metal. After the rough wire is rapidly cooled, it rapidly becomes hot below the temperature at which multiple precipitations occur. When this roughly drawn wire is then cold-opened and made into a wire rod, this wire rod has extremely high tensile strength, relatively high electrical conductivity, and exhibits an extremely glossy appearance. Thus, the main problems arising from the separate processing of each step in the prior art method are discussed in US Pat. No. 3,613,767
by practicing the invention disclosed in the specification.

Although the continuous UJ blue rolling process for aluminum alloys such as 201 was a significant improvement over the discontinuous batch process of the prior art, it nevertheless represents an entirely new method of batch processing. caused a problem. That is, as explained in Japanese Patent Application No. 51-7080 Mei III = q, the method of U.S. Pat. However, the relatively high speeds required also caused solidification shrinkage voids in the cast bar, which made the product brittle and thus had an adverse effect on its drawability and elongation properties.

′Ｘ１された製品に比して改善された。Accordingly, the aforementioned patent application describes an improved continuous method for producing 6201 aluminum alloy rough drawn wire, which eliminates the problems of assimilative shrinkage and lumpiness associated with the method of U.S. Pat. No. 3,613,767. This avoids the formation of precipitated particles and allows the rough wire to be rolled at temperatures that are advantageously within the upper range of the solution range for the 6201 aluminum alloy. ! J4 What is important is the patent application statement If! The method described in the book 504
(i.e., below the temperature at which solidification shrinkage can occur), preferably between 427°C and 504°C.
(800-940°F) and then passed through a heating device located between the casting machine and the rolling mill, in which the temperature of the cast bar is preferably 454°C-616°C (850-1

A substantially superior product is thus obtained, in which the amount of magnesium silicide retained in solid solution in the aluminum matrix is substantially increased, and the ultimate tensile strength, elongation and electrical conductivity are significantly improved by prior art methods. 3

鋳造機の鋳型で連続鋳造棒に連続鋳造する工程。According to the method in the patent application MS, the heating device was placed between the casting machine and the rolling mill to obtain an improved product, but according to the present invention, the heating process is rather placed between the casting machine and the rolling mill. It has been found that better results can be obtained by placing More specifically, the heating device is placed between the rolling mill and the cooling device, and the rolled rough wire passes through it, so that the temperature of the rough wire is within the solution temperature range from the temperature when it is pulled out from the rolling mill. The temperature is raised to an elevated temperature. Preferably, the temperature of the rolling rough wire is 371°C to 566°C (700 to 1050°C)
°F). Therefore, according to the present invention, there is a method for continuously manufacturing aluminum alloy rough wire containing 0.5 to 0.9 wt% silicon, 0.6 to 0.9 wt% magnesium, and the remainder being substantially aluminum. (a) 0.5 to 0.9 wt% silicon, 0.5 to 0.9 wt% silicon;
A step of continuously casting a molten aluminum alloy containing 6 to 0.9 wt% magnesium and the remainder substantially aluminum into a continuously cast rod using a mold of a continuous casting machine.

8, the step of raising the temperature of the cast bar is accomplished by passing the cast bar through a heating device when it is pulled out of the rolling mill in the form of a rough draft, and the temperature of the cast bar is 371. °C to 566 °C (below 700 to 1050 °F
) Provided is a method for continuously manufacturing aluminum alloy rough drawn wire.
圧延機中でマグネシウムシリサイドの若干の析出が起こ
るので、本発明方法は原発明方法に比して、若干優れた
性質を有する最終製品を生成する。Since some precipitation of magnesium silicide occurs in the rolling mill, the process of the invention produces a final product with slightly better properties than the original process.
なぜならばこの後加熱段階（すなわち圧延したのも）は
この種の析出に対抗するからである。荒引線が約７００

べきである。すなわち後加熱段階は固溶体中のマグネシ
ウムシリサイドのωを増加させ、これにより荒引線製品
の改善された性質を得ることができる。This is because this post-heating step (i.e. rolling) counteracts this type of precipitation. The rough line is about 700
It is noteworthy that only about 20% of the magnesium silicide is retained in solid solution upon exiting the mill at temperatures below. That is, the post-heating step increases the ω of the magnesium silicide in solid solution, which can result in improved properties of the rough drawn wire product.
他方において荒引線はこれが圧延機から引出されるとき

進むので、加熱は必然的により短時間に行なわれる。従
って本発明の後加熱操作を実施する場合には、原発明方
法の前加熱操作に必要であるよりも多量の熱エネルギー
を必要とする。On the other hand, since the rough wire advances at a faster rate when it is withdrawn from the mill than the Vi bar advances when it enters the mill, heating necessarily takes place in a shorter time. Therefore, carrying out the post-heating operation of the invention requires more thermal energy than is required for the pre-heating operation of the process of the invention.
