Joining forces: Experts from SMS and Tung Ho Steel. 10 Newsletter 1/2011 Minimills Every year 72,000 t less carbon dioxide (CO 2) Tung Ho Steel, Taiwan: Minimill sets new standards for rebars In mid-2010, Tung Ho Steel Enterprise Corpora- tion, Taiwan, has successfully taken a minimill for rebars into operation which has been built by SMS Meer and SMS Concast. What is so special is that the new minimill in Taoyuan near Taipei can be operated without a conventional reheating furnace. Instead, an inductive heating plant from SMS Elotherm has been integrated. Consequently, Tung Ho saves energy and the environment is less polluted, since 72,000 t less carbon dioxide (CO2) are produced. And the operational costs are also substantially lower. The works bays. Minimal energy consumption. For the generation of energy, Taiwan depends almost 100 percent on oil and gas imported from abroad. The country generates high emissions of greenhouse gases, and as a result of this, the government is making efforts to reduce energy consumption and the emission rate. In response to these efforts, we have materialized an innovative approach for the new minimill of Tung Ho in order to reach a minimum energy consumption. Reheating furnace dispensed with. The new plant optimally implements the basic minimill concept: short ways and a direct linkage of the rolling mill to the steel plant. The hot billets running out of the continuous caster (with a capacity of 40 to 45 t/h per strand) are immediately brought to a uniform temperature in the inductive heating plant. Then, the billets run directly into the rebar rolling mill. In this way, a gas- or oil-fired reheating furnace upstream of the rolling mill could be dispensed with. Under certain conditions, even an inductive heating is not required since the billets are shaped in such a way that they hardly lose any heat during the subsequent production process.
Good for the environment and for returns. Eyery year the steel plant with electric arc furnace, ladle furnace and a five-strand billet caster from SMS Concast is producing 1.2 million t of billets and the rebar mill from SMS Meer has a capacity of 800,000 tpy. Due to the innovative energy concept, Tung Ho Steel every year reduces the emission rate of carbon dioxide (CO2) by 72,000 t, of sulfur dioxide (SO2) by 410 t and of nitrogen (Nox) by 225 t. In addition to this, the investment costs for the inductive heating plant are approx. 25 to 30 % less than with conventional furnace concepts. At the same time, the operational costs for each t of rebars are reduced by approx. 25.00 US dollars. Excellent references. Dr. Joachim Schönbeck, President and CEO of SMS Meer: ”This mill shows yet again that our customers benefit from integrated all-inclusive solutions of the SMS group. Two plant manufacturers which are leaders in their respective fields, SMS Concast and SMS Meer, join together their innovative concepts within a seamless process chain. In doing so, they spare our business partners from time-consuming and costly interface problems – and thus allow the mill to be put into operation early.” Reliable and smooth casting. The innovative energy concept with inductive heating reduces the carbon dioxide rate every year by 72,000 t. In the minimill segment, SMS is one of the worldwide leading plant manufacturers with refer- » ences in the whole world. Currently, we are building large plants in Bahrain and Saudi Arabia.
