摘要： A plant for the continuous casting of aluminum strip, according to current construction type, has two counterrotating continuous casting rolls (1, 2), between which a casting gap (4) is formed. According to the present invention, the 1. continuous casting roll (1) is made of a copper material at least in its circumferential edge region, and the other, 2. continuous casting roll (2) is made of a steel material at least in its circumferential edge region. The copper material should have a thermal conductivity λK of 230 to 260 W/m·K, and the steel material should have a thermal conductivity λS of 30 to 40 W/m·K. Rejecting the prevailing idea that casting can only be performed with two continuous casting roll materials of the same kind, so as to ensure uniform crystal growth, a continuous casting roll pairing of steel and copper is provided in the present invention. In order to ensure a qualitatively high value casting microstructure, the difference in the thermal conductivity of the continuous casting rolls should not exceed a factor from 5 to 9. A ratio of thermal conductivity λK of the copper material to thermal conductivity λS of the steel material of 6:1 to 8:1 has proven particularly favorable.

摘要： An aluminum alloy strip of high surface homogeneity, intended for applications requiring good visual quality or specific optical properties, such as reflectors and anodized plates for construction and decoration. The strip may be characterized by an upper side having, after a 1 &mgr;m thick sulphur anodic treatment, an optical roughness value SN measured on three 5 cm longitudinal sections and three 5 cm transverse sections, such that there is mean variation on each section, defined by the ratio: (Maximum SN−minimum SN)/Mean SN which is less than 20%, and a difference &Dgr;SN=SN max−SN min which is less than 20.

摘要： A process for manufacturing a strip of aluminum alloy having high surface homogeneity with an upper side showing after a 1 μm thick sulphur anodic treatment, an optical roughness value SN measured on three 5 cm longitudinal sections and three 5 cm transverse sections, such that its mean variation on each section, defined by the ratio: (Maximum SN−minimum SN)/Mean SN is less than 20%, and the difference ΔSN=SN max −SN min is less than 20. The strip is manufactured by continuous casting between two cooled rolls from a casting tank containing the liquid metal connected to an injector, and feeding the liquid metal into the gap between the two rolls. The injector has an upper lip recessed by at least 2 mm with reference to a lower lip of the injector.
