Baowu Maanshan Steel’s BF “A” blows in, breaking two records

CISDI broke two Chinese steel records in its innovative, ultra-fast revamp of Masteel’s first 4,000-cubic-metre blast furnace.

The plant was shut down for just 85 days while the furnace, which had operated since 2007, was rebuilt and upgraded to smart green standards.

The two segments of the furnace proper were dismantled and slid out of the furnace to make way for their replacements.

The new dry dedusting system was assembled offline to achieve modular installation to the designated position.

A first for China, these innovative rebuild technologies were applied and enabled the furnace to blow in after only 85 days of shutdown - 15 days ahead of schedule.

CISDI took on technical leadership and critical equipment supplies. Its team took just 15 months to complete all designs, beating its record for previous similar projects by eight months, and creating a strong position for commissioning and blowing in.

CISDI, a leader in fast revamp core tech, applied a 3D digital design method to create optimised solutions.

The rebuild means the modernised furnace “A” will operate to smart, long-campaign, high-output and low-consumption standards.
