The most advanced power saving technology in EAF Introduction to ECOARC™
JP Steel Plantech Co. has developed “ECOARC™”, a high efficiency EAF having the most advanced energy recovery and environmentally conscious technology in the Mini-Mill industry. ECOARC™ uses high temperature exhaust gas for preheating scrap charged into “shaft type” pre-heating chamber attached directly to the furnace shell. In addition, the gas is used to treat unwanted chemicals from the waste gas in a combustion chamber with very little use of extra fuel. Only ECOARC™ has these features because of its high level air tightness to prevent air infiltration into the scrap preheating shaft and the furnace.
Six ECOARC™ have already been put into commercial operation in Japan, South Korea and Thailand which have achieved approx. 30 % reduction of energy. In this paper, the method of improving energy efficiency by the utilization of waste heat is described and ECOARC™ under commercial operation are introduced.No. 2015-02

THE NEW PROGRESS ON ECOARC™ IN THAILAND
To reduce energy consumption in the steel industry in Thailand, several model projects supported by the governments of Thailand and Japan were implemented. As one of them, an ECOARC™ was installed in UMC Metals Ltd. and started up in November 2012. The ECOARC™ is a high efficiency electric arc furnace with a scrap preheating system developed and designed by JP Steel Plantech Co. It was a brown-field project which replaces the existing conventional EAF with the ECOARC™, maximizing reuse of the existing facilities except key components of the ECOARC™, in order to minimize initial investment. After the start-up, all the targets of this project were achieved only within 2 months after the start-up in spite of the first and brown-field ECOARC™ in Thailand.
