Process and Technical Study on Production of SPA-H Steel at Benxi Thin Slab Caster

摘要

Technological development has been achieved for FTSC (flexible thin slab caster) to produce SPA-H steel. Through chemical composition control, temperature adjustment, mold powder choice and secondary cooling water setting for continuous casting etc., the longitudinal crack problems of slabs at FTSC are resolved. With certified surface and internal quality, the performance of FTSC slab plates is better than conventional slab plates. SPA-H steel has been produced in batch at Benxi continuously thin slab casting.
