Either the plate is rolled and then cold rolled at a processing rate of 20 to 95% to obtain an intermediate thickness, or a coil with a plate thickness of 12-1 or less is directly cast by continuous casting without going through the hot rolling process. Cold rolled to an intermediate thickness,
Then, after performing intermediate annealing on the intermediate plate thickness,
It is produced by final cold rolling at a reduction rate of 20-95% to obtain the required mechanical properties.

Among these properties, regarding the burning property of (A),
The effectiveness of the method of strengthening the image area by exposing and developing the 18th plate using an aluminum alloy plate as a support in the usual manner and then heat-treating it at high temperature (so-called burning treatment) was disclosed in the Japanese Patent Publication No. 44. It is described in detail in Publication No.-27243 and Japanese Patent Publication No. 44-27244,
The heating density and time of such burning process depends on the type of resin forming the image, but it is 200 to 280
Celsius for 3 to 7 minutes is customary. However, in recent years, it has become desirable to perform the burning process at a higher temperature in order to improve printing durability and shorten the burning process time. However, when conventionally used aluminum alloy plates are heated at high temperatures of 280°C or higher, recrystallization occurs and the strength is extremely reduced.
The lack of firmness of the plate makes it extremely difficult to handle the plate, resulting in drawbacks such as the impossibility of setting the plate on a printing machine and the difficulty in registering the colors of the plate in multicolor printing. Therefore, there is a strong desire to develop an aluminum alloy plate with high heat resistance that can withstand burning treatment at high temperatures, that is, an aluminum alloy base plate for printing with excellent burning properties.

In order to achieve the above-mentioned object, the present inventors conducted extensive experiments and tests on the chemical components of aluminum alloy blanks that affect the burning properties and the intermediate annealing conditions during the blank manufacturing process.
As a result of repeated consideration, we found that 5 of the materials have the highest burning resistance.
It was discovered that ill and intermediate annealing temperature have a strong influence, and this invention was made.

As mentioned above, the burning property is related to the amount of 81 and the intermediate annealing temperature, and the smaller the amount of S1 and the higher the intermediate annealing temperature, the less the decrease in strength after the burning process. According to detailed experiments by the present inventors, it was found that the amount of Si is at the intermediate annealing temperature T
Regarding ('C), it has been found that when the range of formula (1) is satisfied, the decrease in strength after the burning process can be suppressed to a level that does not cause any practical problems. If the range of this equation (1) is illustrated, it is the area to the right of the straight line AB in FIG. In the region to the left of the straight line AB, the strength decreases significantly after the burning treatment, and for example, after the burning treatment at 270° C. for 7 minutes, the 0.2% yield strength becomes less than 5 kQ, which is not preferable.

Furthermore, if the amount of Si exceeds 2.5%, the color tone after the surface roughening treatment will become too dark, making it difficult to see the image area when inspecting the image area after development, so the upper limit of Sin is 2.5%. %. Furthermore, the intermediate annealing temperature is 300 to 550 as explained later.
It must be within the range of °C. Therefore, if these conditions are also shown in FIG. 1, the amount of S1 and the intermediate annealing temperature T
It can be seen that it is necessary to fall within the shaded area in FIG.

Ti is added to make the crystal grains of the ingot uniform and fine, but if it exceeds 0.10%, its effect will be saturated and it will only unnecessarily increase costs.
.. It was limited to 10% or less. As a means of adding T1 for this purpose, rather than using an Al-Tl master alloy, Al
The effect is greater when the 1-Ti-8 master alloy is used. In this case, B is contained, but the content of 8 is preferably suppressed to 0.02% or less in order to prevent the generation of linear defects due to Ti 82 particles.

In other words, in the process up to intermediate annealing, the surface of the semi-continuously cast ingot is usually removed with a solidifying agent, then homogenized if necessary, and heated to a predetermined temperature before hot rolling. The coil is then hot rolled and then cold rolled at a processing rate of 20 to 95%, or a continuously cast coil with a plate thickness of 121 mm or less is directly cast and cold rolled as is without going through the hot rolling process. Adopt a process. After reaching the intermediate thickness in this way, it is subjected to intermediate annealing at 300 to 550°C for up to 24 hours, followed by final cold rolling at a working rate of 20 to 95% to obtain the necessary mechanical strength. administer. The reasons for limiting the intermediate annealing conditions are as follows. In other words, 11th year of middle school
If the 1m annealing temperature is less than 300℃, sufficient recrystallization will not occur, making it unsuitable for intermediate annealing.On the other hand, if the temperature is 550℃ or higher, secondary recrystallization will occur, causing the recrystallized grains to become significantly coarser, and further oxidizing the surface. This causes unevenness and blistering, making it unsuitable as a base plate for printing. Note that the intermediate annealing temperature is actually regulated also by the relationship with the amount of 81 in the material as described above. On the other hand, if the medium annealing time exceeds 24 hours, the annealing effect will be saturated and it will only be economically disadvantageous.
Maximum time is 24 hours.
