| Abstract: | Purity problem of round billet steel was solved by optimizing parameter of tundish. Lubricating of mould and surface quality of billet were solved by application of new oscillator of mould. Center shrinkage cavity and rarefaction of billet was solved by electromagnetic stirring.The electric arc furnace and caster have been revamped with high efficiency in TPCO.By the technology revamping of caster, the annual output increases up to 900 000 t from 600 000 t, and the comprehensive qualified rate of casting billet was 99.66%. |
