On 25 November 2019, Dung Quat Blast Furnace #2 was successfully blown-in by Hoa Phat Steel, Vietnam.
This is the second of four greenfield Danieli Corus Blast Furnaces that are being built under a single contract signed in Summer of 2017. Blast Furnace #1 was blown-in on 29 June 2019 – within 24 months after contract signature.
Each of the four furnaces will have a 1,080-m³ working volume, and each is designed for an annual production of 1 million tons. The first two furnaces are in operation and Blast Furnace #3 and #4 are clearly distinguishable in the Dung Quat skyline. These furnaces will be commissioned within 2020.
After completion, the plant will add 4 Mtpy to Hoa Phat's steelmaking capacity.
This quick scale-up with Vietnam’s leading steel producer demonstrates the competitiveness of Danieli Corus blast furnace technology in mature as well as emerging steel industries.
The 14-m CCM with 4 strands was supplied in 2008 to produce 320x425-mm sections and later revamped by Danieli in 2014 to add round sections up to 380 mm. The caster originally included 9 soft-reduction modules per strand.
The fast ramp-up of the Danieli MIDA plant at Nucor Steel Sedalia is continuing.
Real Steel Corporation awarded Danieli the contract to supply a new high-speed rolling mill to produce deformed bars in the range of 10 to 32 mm-dia, starting from 150-mm square billets weighing up to 2,000 kg.
A Final Acceptance Certificate was signed at PT Krakatau, Indonesia, for the electric and automation revamping of hot skin-pass mill.
Currently in its engineering phase, the high-speed bar mill of Luzhou Xinyang I&S, China, will produce 1.4 Mtpy of rebar products in the range from 12- to 40-mm diameter, for grades HRBF 400E - 500E. Starting from 165-mm diameter billets weighing up to 2,500 kg, the new mill will operate at speeds up to 240 tph.
Reliability and performances of caster rolls are two of the main key factors to increase productivity and reduce plant OpEx.
