Abstract

Provided is a method for continuously casting slabs which is characterized by employing a moveable roll reduction device provided with rollers capable of reducing slab thickness and capable of moving in a vertical direction along the slab from a mold and after drawing of a slab is completed carrying out reduction as the rollers move in the vertical direction along the halted slab. The movement direction of the rollers when reducing the slab may also be a vertical upward direction. Furthermore a cross section of the slab may also be round. According to this continuous casting method porosity and voids in the center of the slab and shrinkage cavities and voids in the top part of the slab can be reduced at a low equipment cost and without a drop in surface quality regardless of the size of the cross sectional area.
