A rotary hearth furnace 1 built at WISCO, one of 2020’s major engineering projects in China’s Wuhan City, is operating with stable indicators.

CISDI designed the RHF plant and supplied the critical equipment.

A sludge pre-treatment line and two rotary hearth furnaces, each with a projected annual capacity of 200,000 tonnes, were built to recover the steel plant's iron-bearing resources.

The rotary hearth furnace features direct reduction tech and was exclusively developed by CISDI Thermal & Environmental Engineering Co. It is a highly effective solution for turning waste products into energy.

Iron-bearing solid wastes are recovered and reused in production procedures instead of generating secondary pollution. Zero solid waste is discharged from the steel complex, which makes a valuable contribution to the urban circular economy.

The construction met severe challenges during the pandemic. The first known infections from COVID-19 were discovered in Wuhan, the capital of Central China’s Hubei province.

Our team stayed committed to their duties onsite and collaborated with WISCO and the builders after lockdown restrictions ended.

Scientific approaches to plans and controls ensured the project met all quality standards and completed on-schedule.

CISDI is proud to be playing a part in helping the Baowu WISCO plant, which is in Wuhan’s Qingshan District, develop eco-friendly measures which protect the city’s environment.

The plant’s green production credentials now match those at Baowu’s Zhanjiang and Shanghai bases, where CISDI’s rotary hearth furnaces are already running smoothly.
