Another milestone achieved at Minmetals Yingkou Steel

A new KR desulphurisation system has been successfully hot-commissioned at the steelmaking shop in Yingkou Steel, Northern China.

The KR equipment, which is working stably, can treat an average of 115 tonnes of hot metal per vessel and achieve an annual treatment capacity of 1.426 million tonnes.

It has been arranged in a horizontal configuration inside Yingkou’s workshop and extends in an easterly direction from the existing hot metal pretreatment and slag shops.

Commissioning marks a second contractual milestone achieved at Yingkou by CISDI - the first being the hot-commissioning of basic oxygen furnace 3 in April.

CISDI is providing services to Yingkou Steel to an EPC mode and as part of that task, BOF facilities were upgraded to a CISDI-SACS patented product. In addition, new facilities were installed at the existing meltshop. The additions included a KR desulphurisation system, a semi-steel furnace, an LF, RH furnace and a single-strand heavy continuous caster.

The KR system enables Yingkou Steel to apply a mechanical stirring process which removes sulphur from hot metal before it is discharged into the BOF.

This improves hot metal treatment efficiency and improves hot metal quality for steelmaking - a step towards enhancing the steelworks’ competitiveness.
