On March, 29^th, 2011, No.4 BF of Shougang Shuicheng Iron & Steel Co., Ltd undertaken by CISDI on EPC basis was officially ignited. On 30^th of the same month, hot metal was successfully tapped from the BF.

The startup of Shougang Shuicheng Steel No.4 BF marks a transition from 3 million tons capacity to 5 million tons in Shuicheng Steel, signifying an important step by Shuicheng Steel towards building quality long product base in West China. The BF features advanced metallurgical processes in China such as fine burden, high blast temperature, high pressure, high rate of oxygen enrichment and high PCI ratio with equipment technology reaching advanced level of the same grade in China. In particular, system optimization and corresponding input has been made in fields of general layout & transportation, process flow, automatic control and energy conserving & emission cutting.

During the construction, many difficulties have been overcome such as many terraces, complicated terrain, narrow construction site, interferences in construction and long freezing weather. The project has set up a world record in building 2500m³ BF and its auxiliary facilities in 68,000m² area and witnessed a miracle of building a BF project with smallest floorage, most terraces and most compact process flow among the same capacity BF and in the same industry.

1 CISDI is highly appraised for its great skills in accommodating a BF plant on such challenging site conditions.

2 Many difficulties popped up in the construction. But thanks to concerted efforts of CISDI and other involved parties, the project construction schedule can be effectively pushed forward.

3 CISDI enjoys top level engineering and organization capability in China.
