Abstract

The quality assurance of technological process of obtaining and the specified quality of continuous cast billets from copper alloys at performance improving of continuous casting machine is considered in the paper. The damageability level was tested by the assessment of tensile strength of samples of continuous cast billets at the following operating modes of the continuous casting machine: billet motion was carried out progressively during overcoming the static friction force at various values of the billet motion frequency, the billet motion was carried out at reverse motion when overcoming the static friction force at various values of the billet motion frequency. It was found that at joint application of reverse billet motion in the mold during overcoming the static friction force and increase in the billet motion frequency there is a decrease in the billet damageability parameter. As a result, the technological parameters for the continuous casting process, the adjustment of which allows a significant increase in the billet quality, are given.
