摘要：

In order to enhance the uniformity of cladding copper layer distribution over the bimetallic bar perimeter and length, the shape of the classical horizontal and vertical oval passes were modified. The rolling was carried out in the designed modified elongating grooves. The round Al-Cu bimetallic bars with an outer diameter of 22 mm and a copper layer share of 15 and 30%, after explosive cladding, were rolled on a D150 two-high shape mill. As a result of rolling in 4 passes, bars of a diameter of about 16.0 mm were obtained. By applying the modified grooves to the rolling of Al-Cu bimetallic bars, the stability of the rolling process was improved, whereby, finished bars with a uniform and tight cladding layer distribution over the core and small diameter dimensional deviations was obtained. © (2015) Trans Tech Publications, Switzerland.
