Abstract

The productivity of vertical upwards continuous casting of aluminium wires depends mainly on effectiveness of the cooling process in the mould.

The aim of this actual work is to investigate the structure of cast aluminium wires, depending on casting speed. The related mechanical properties such as tensile strength and hardness of investigated samples are determined.

Depending on the function of production, the optimal technological parameters (temperature of liquid aluminium, casting speed and cooling rate) for several wire diameters of continuous cast aluminium wires are recommended.

Keywords: upwards continuous casting, combined mould, structure, mechanical properties
