Description

technical field [0001] The invention relates to a composite plate preparation technology, in particular to a steel-wear-resistant copper alloy composite plate, a preparation device and a preparation method thereof. Background technique [0002] Copper-lead (Cu-Pb) alloy has strong bearing capacity, high fatigue strength and wear resistance when working under high speed and high pressure, high thermal conductivity, low friction coefficient, good wear resistance and corrosion resistance, and is an ideal self-lubricating anti-friction Material. After compounding with steel, it forms a steel-copper-lead alloy composite material, which has both the wear resistance of copper-lead alloy and the strength of steel. Therefore, steel-copper-lead alloy composite material is one of the leading bearing materials for the development of new automobiles. [0003] At present, there are mainly two methods for preparing copper-steel clad plates, hot rolling and liquid rolling. In the former, ...
