| Abstract: | The surface transverse crack is one of the common surface defects on the high-strength Niobium bearing steel for continuous casting slabs.It is an important reason that the scars will appear on the surface of the steel sheet after the slab being rolled.Since 2007,the third steelworks of Handan branch of Hebei iron and steel group have adopted the advanced mold hydraulic oscillation platform to increase the oscillation precision,improving the fan-shaped equipment precision of the slab continuous caster,solving the leakage problem of many equipments,optimizing the water distribution of the slab straightening area and successfully removing the problem of surface transverse crack of the high-strength Niobium bearing steel. |
