CISDI is supplying advanced technical equipment for the rebuild of an ageing blast furnace at Ukraine’s largest integrated steel complex.

Blast furnace No 9’s top equipment at ArcelorMittal’s Kryvyi Rih Plant will be supplied by CISDI, which has already been contracted as supplier of the blast furnace proper and slag granulation systems for the rebuild. 

The top equipment is a patented, no-bell product jointly developed by Baosteel, CISDI and Qinye Heavy Industry. 

Blast furnace No 9, built in 1974, has a volume of 5,000m³ and is one of the world’s earliest large blast furnaces.

The Kryvyi Rih Plant is ArcelorMittal’s most significant steel base in Eastern Europe and the refurbishment will become a benchmark of the company’s technological transformations. 

A key part of CISDI’s critical tech for high-efficiency, low-consumption large blast furnaces, the BCQ top system plays a vital role in achieving smoother operation. 

CISDI is responsible for engineering the BCQ top system and has innovatively redesigned the distributor’s hydraulic control and the critical parameters.

This creates a simpler structure, minimises running problems, makes operation and maintenance easier and enables the top to better withstand the high temperatures and high pressures associated with blast furnace operation. 

BCQ top equipment has also been exported to steel plants in South Korea, Brazil, Indonesia, Vietnam and Turkey. 

CISDI has made continual advancements to the critical tech of its top, stove, granulation and other core equipment for large blast furnaces, increasing their efficiency, reducing their energy consumption and increasing their service life.

These technologies and equipment are enabling plants across the world to achieve greener and more intelligent manufacturing methods.

They have been successfully applied to 27 large blast furnaces in China and overseas.
