Donghai Special Steel’s new slab caster passes hot test

CISDI’s package-supplied slab caster 2 for Donghai Special Steel has passed its hot test on three consecutive heats.

Slab produced had a cross section size of 200mm x 1,010mm and a steel grade of Q195.  The casting speed was 1 metre per minute.

To upgrade the product mix, a pair of new two-strand slab casters has been created in the Meltshop 1 which previously housed an eight-strand billet caster.

The target specification of slab is 180-200mm in thickness, with a reserve thickness of 210mm, and 900mm-1,300mm in length.

The daily output of qualified slabs should reach 5,000 to 6,000 tonnes, and the annual capacity target is around three million tonnes.

Most of the cast slabs will be directly hot-charged via the roller table to the rolling mill.
