Application of New Continuous Casting Technologies in TISCO New Stainless Steel Project

The general situation of continuously cast slab production technologies and equipment in TISCO's new stainless steel project, some new continuous casting technologies, such as hydraulic non-sinusoidal oscillation technology of mould, soft cooling of the mould, dynamic distribution of secondary cooling water, continuously cast stainless steel slab surface quality classification system etc. during our development of the high quality stainless steel slabs were introduced in this paper. With the development and application of the new clean steel technology and the new continuous casting technologies for stainless steel, [O] content in the austenitic stainless steel of TISCO has been controlled below 35 ppm, about 70% of the slabs are hot rolled without grinding.
