Researches Concerning the Correlation of the Semiplanetary Rolling Process Factors
An available solution of the elimination of the superficial cracks network at the continuous cast slabs is the semiplanetary rolling. The application of a semiplanetary rolling mill at the exit of slab from the curve zone of the continuous casting machine leads at the slab unbending. For real constructive conditions of the geometry of casting machine, the establishing of the factors of semiplanetary rolling process, is necessary. The researches showed in this paper, worked at a lab semiplanetary mill, demonstrate that the bending of the linear body or the unbending of the curve body is possible. At the same time is establishing a correlation between the geometrical factors of body and the semiplanetary rolling factor – the relative reduction of thickness.
