Constant improvements to continuous annealing process technology are necessary for the production of bothnew and traditional steel grades to provide good formability and ductility and also gives higher mechanicalproperties when combined with correctly tuned steel chemical compositions.One vertical and one horizontal type furnace are to be started up at Acciaieria Arvedi S.p.A. (Italy) in 2011,these furnaces form part of the Continuous Galvanizing Line (CGL) in the Danieli Cold Mill Complex, thiscomplex also includes a six-high Tandem Coil Mill and Push-Pull Pickling Line.The furnaces will be able to match any market requirements for different annealing cycles, thus combininghigh performance with low investment and transformation costs. Short heat-up, long soaking, both slow andrapid cooling have all been included in equipment design to give any type of annealing curve and include alarge group of steel grades commonly required by the market. Planned expansion will allow for additionalslow cooling and extended over-aging time. High performance direct flame burners and radiant tubes fed bynatural gas are the key to guarantee strip quality and low maintenance costs. Flexible rapid jet coolingperforms different cooling rates to accommodate the metallurgy of several different steel grades. |
