Abstract

The invention discloses a hot rolling production technology of a copper-aluminum composite board. The hot rolling production technology comprises the following technological steps of raw material preparation, surface treatment, heating, rolling bonding, annealing and slitting, specifically, the thickness and the width of an aluminum strip and a copper strip are selected according to needs; surfacepolishing treatment is conducted on the aluminum strip and the copper strip respectively; the aluminum strip and the copper strip are heated in an upper layer heating furnace and a lower layer heating furnace correspondingly; the heated aluminum strip and the heated copper strip enter a rolling mill synchronously to be rolled and bonded, and the copper-aluminum composite board is obtained; annealing is conducted on the copper-aluminum composite board which is subjected to rolling and bonding by adopting a bell type heating technology; the annealed copper-aluminum composite board is cooled tobe at the normal temperature, and slit into flat boards. According to the hot rolling production technology, hot rolling bonding of the copper-aluminum composite board can be achieved by controlling the heating temperatures of the copper strip and the aluminum strip respectively, bonding can be achieved through one-time rolling, the problems that the rolling force is large and rolling needs to beconducted for many times in the cold rolling bonding process are solved, the utilization property of the composite board is improved, the production efficiency is increased and the cost is lowered.
