Title:
METHOD FOR MANUFACTURING SLAB AND CONTINUOUS CASTING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2019/167868
Kind Code:
A1
Abstract:
A method for manufacturing a slab by means of continuous casting equipment comprising a twin-drum continuous casting device, a cooling device, an inline mill, and a take-up device, wherein a rolling analysis model is used to calculate a friction coefficient from measured values for the rolling load and forward slip rate obtained during rolling of the slab, a lubrication condition during rolling of the slab is controlled such that the friction coefficient is within a prescribed range, and when Orowan's theory and a deformation resistance model formula based on Shida's approximation formula are used as the rolling analysis model to calculate the friction coefficient from the measured values for the rolling load and forward slip rate, the prescribed range is 0.15 to 0.25.
