120-t EAF with Conso-Oxygen technology for reduced energy consumption. The EAF has a tap-to-tap time of 43 minutes. 12 Newsletter 1/2011 Minimills Layout of the minimill at Tung Ho Steel Steel plant with 120-t EAF The electric steelworks built by <strong>SMS</strong> Concast provides a 120-t electric arc furnace with dedusting system. The power consumption of the furnace is 120 MVA. To supply additional energy, we apply our Conso oxygen technology (oxygen/gas burner) which reduces power consumption and increases productivity at the same time. The tap-to-tap time is 43 min. Downstream of this is a ladle furnace which is used for exact temperature setting providing liquid steel for secondary-metallurgical miroalloying. Furnace tapping. The continuous casting plant has five strands and is expandable by a sixth strand.
Five-strand billet caster The casting machine has five strands with a casting radius of 10.25 m. An expansion to six strands has been considered in the layout. The range of dimensions comprises square billets in the formats of 130, 150, 160 and 200 mm. The special equipment includes among others the Invex® mold tube technology for high-speed casting and the hydraulic mold oscillation systems. The casting machine is able cast billets in various sizes in a parallel mode. Rebar mill for bars with diameters from 10 to 43 mm In front of the rebar mill the billets are heated to an uniform temperature by the inductive heating plant, if necessary. The downstream rolling mill includes 14 mill stands in horizontal/vertical and tiltable configuration. A compact design of the ”HL” stands ensures that close tolerances of the finished products are maintained. Bars with small diameters are finish-rolled in two finish-rolling blocks with six rolling units in V arrangement. Straight bars are transported with up to 40 m/s to the cooling bed by the H.S.D.® (High-Speed Delivery) system. Then they pass through the finishing facilities. The roughing train of the rolling mill. Induction heating section. The minimill is designed for 800,000 tpy of rebars. Newsletter 1/2011 13
