Вплив технологічних параметрів розливання і кристалізації сталі на якісні показники безперервнолитої заготовки

Abstract

In order to increase the speed of casting high-carbon liquid steel, technological modes of casting and crystallization of the continuously cast billet have been tested during the research process.

As compared to the billets, which were cast using conventional cooling modes, reduced affection with cracks and central porosity has been achieved.

The conducted research has shown that during production of continuously cast billets, made of high-carbon steels C80D and C86D, the drawing (casting) speed could be increased to 3.2 m / min., which will make it possible to reduce the process time of one heat without sacrificing quality indicators of the billet.
