    • A method of producing a planographic printing plate support in which after aluminum is continuously cast directly from molten aluminum into a thin aluminum plate, the aluminum thin plate is subjected to cold rolling, heat treatment and flattening to obtain an aluminum support. The aluminum support is then subjected to surface toughening. The components of the aluminum support areFe: 0.4%-0.2%,Si: 0.20%-0.05%,Cu: not larger than 0.02%, and the Al purity is not smaller than 99.5%. After continuous casting, Fe in a range of from 20% to 90% of the Fe total content exists in a grain boundary and the rest of Fe exists as a solid solution in grains. In this case, it is preferable that in a section perpendicular to the direction of continuous casting, the grain size is in a range of from 2 .mu.m to 500 .mu.m.
    • 一种平版印刷版支撑体的制造方法,其特征在于,将铝从熔融铝直接连续铸造成薄铝板后,对铝薄板进行冷轧,热处理,平坦化,得到铝载体。 然后将铝载体进行表面增韧。 铝载体的组分为Fe:0.4%-0.2%,Si:0.20%-0.05%,Cu:不大于0.02%,Al纯度不小于99.5%。 在连续铸造之后,在Fe界限中存在Fe总量的20〜90%范围的Fe,其余的Fe作为固体颗粒存在。 在这种情况下,优选在与连铸方向垂直的截面中,粒径在2μm〜500μm的范围内。

    • An electrolytic treatment apparatus for continuously electrolyzing an elongated product of aluminum or an aluminum alloy at a low electrolyzing voltage and reduced amount of electric power. The apparatus includes at least one electrolytic section and front- and rear-side power supply section disposed respectively at front and rear sides of the electrolytic section in the longitudinal direction of the elongated product in the electrolytic section. Each of the power supply sections contains at least one electrode, and the electrolytic section contains a plurality of electrodes. The electrolytic section and the power supply sections are filled with an electrolyte in which the elongated product and the electrodes is immersed. A plurality of power sources are provided, with an electrode of the electrolytic section at a front-side portion thereof being connected to an electrode of the front-side power supply section through one of the power sources, and another electrode of the electrolytic section at a rear-side portion thereof being connected to an electrode of the rear-side power supply section through another of the power sources. The invention also provides an electrolytic treatment method by which the above apparatus is operated.
