SLAB CUTTING METHOD IN CONTINUOUS CASTING OF STEEL, WHICH CAN BE IMPLEMENTED BY CHANGING THE BLADE STRUCTURE OF AN EXISTING HYDRAULIC SHEARING MACHINE

摘要

PURPOSE: A slab cutting method in continuous casting of steel is provided to cut slab without a collision between saw blades by freely controlling the pressing end points of the saw blades.;CONSTITUTION: A slab cutting method in continuous casting of steel bites and cuts slab(31) by pressing a pair of V-block type cutting saw blades perpendicularly to the axis of the slab. The pair of cutting saw blades are arranged to be misaligned with each other in a slab drawing direction and cuts the slab by pressing the slab over the middle of the slab thickness to provide shear and tension while preventing a collision in the middle of the slab thickness. The amount of misalignment between the saw blades is 1-5% of the slab thickness.;COPYRIGHT KIPO 2013
