Abstract For the conventional vertical-curved slab caster, the design of roller arrangement and the relationship among the radius of curved zone, the length of bending zone, the length of straitening zone and the height of caster are introduced. The optimization method of designing roller arrangement parameters is proposed, and the stress of the caster before and after optimization is briefly analyzed. Results indicate that, for the vertical-curved slab caster, when the length of caster and the height of vertical zone are given, the radius of curved zone and the length of bending zone could be determined by the height of caster. The straightening length of the casting machine can be calculated according to the height of the casting machine, the radius of curved zone, and the length of bending zone. The optimized results obtained by computer program indicate that bulging force and the withdrawal resistance for moving strand could be decreased by decreasing the radius of curved zone and increasing the length of straitening zone.

Key words： continuous casting slab caster roller arrangement optimization method roller reacting force withdrawal resistance
