Chinese steel producer Tangshan Quanfeng has signed a maintenance services contract with Primetals Tangshan Technology Services (PTTS). Over the last three years, PTTS has provided Quanfeng with high-quality offline services for the entire thin-slab casterat its plant located in Tangshan, Hebei province, China.The services have included the refurbishment ofsegments, and rollers.

Higher productivity

Thanks to the quality of the maintenancework, Quanfeng could achieve higher productivity, develop additional steel grades, and produce steelsof higher quality. Therefore, Quanfeng has now decided to extend the contract for another three years. With experienced workers and expertsin the field of metallurgical services, PTTS will provide maintenance services for the entire thin-slab caster.

Combines casting and rolling

Established in 2018, Tangshan Quanfeng is owned by Donghua Steel, a part of the larger Shuoyin Group. Donghua Steel has an annual capacity of 5.5 million tons of liquid steel and produces high-strength rebar for the domestic and international markets. Its endless casting and rolling process features key equipment and process control systems from Primetals Technologies.

Thinner and stronger

The produced strip is thinner than conventional products – it is less than 1.5 millimeters thick– and has higher strength. At about 180 meters in length, this casting and rolling process is far more compact than conventional casting and rolling plants. Thanks to this innovative solution, both energy consumption and CO₂ emissions are heavily reduced.

PTTS was established in 2017 and is a joint venture between Primetals Technologies and HBIS Tangsteel. Itis headquartered in Tangshan and has operations in several locations in China.

PTTS provides comprehensive services in off-line maintenance, equipment refurbishment, condition monitoring, and operational support for slab casters.
