Steelmaking byEAF ProcessInnovation for reduced costs anda cleaner environment

11 12

Cost reduction is an ongoing theme for all mills, while environmental issues are becoming more important. To address these two conflicting issues at the same time, Steel Plantech developed the ECOARCTM, an innovative, new-generation ecological and economical arc furnace.

A conventional ladle furnace (LF) has three individual masts with electrode arms for constant impedance control. However, ladle furnace operations involving the flat bath and submerged arc do not require individual electrode regulators. Based on this idea, Steel Plantech developed the Single-Mast Furnace (SMF), a three-electrode simultaneous-control ladle furnace.

Steel Plantech’s totally balanced design, improved water-cooled panels and slag foaming technology have brought the high-power, high-impedance long-arc AC-EAF to fruition. One of our newest results: design parameters optimized to handle the power consumption of high-ratio DRI melting and to minimize power consumption. Satisfactory operating results, through a long arc for flat bath operation, attest to the Steel Plantech EAF technology.

Steel Plantech developed AUTO-ARC for arc furnaces and AUTO-LF for ladle furnaces. These are computer systems with versatile functions that enable both high reliability and low cost and thus contribute to stable operation at steel mills.

In one of Steel Plantech’s main business fields, based on our complete melt-shop design experience, and backed by long years of production experience as a steelmaker, we provide not only EAF equipment and all auxiliaries, but also comprehensive metallurgical and operation technologies.

• Minimized PCD of the graphite electrode• Well-balanced impedance among phases and high power• Easy maintenance• Simple mechanical configuration and prefabrication• Simple mechanism, minimal moving parts and insulation

DRI Base 160t UHP AC-EAF at EZDK (Former ASDK)• Heat size: 160 metric tons (tapped steel)

• Raw material: 90%DRI

• Electrode: 28in.

• Others: Conductive electrode arm, argon bottom bubbling, door and side wall oxygen lances and other required auxiliary equipment

• Production management and heat tracking• Heat profile calculation and power input control• Comprehensive operator guidance• Data acquisition and storage of 10,000 charges• Data acquisition, report generation and statistics analysis

AC Electric Arc Furnace (AC-EAF)

With one long arc at its center, the DC-EAF furnace can be called the ultimate long-arc AC-EAF with zero electrode PCD. Together with the merits of the long arc, the well-known turn coil system enables molten steel agitation and perfect arc deflection control. Additionally, the maintenance-free long-life bottom electrode (2,000-4,000 heats) ensures high availability of the DC furnace.

How to promote environmental responsiveness, energy savings and cost reduction is an ongoing theme for all mini mills.Steel Plantech supplies all-in-one mini mills to meet these goals with its unique and innovative technologies.

Steel Plantech’s fully automated scrap charging facilities achieve high productivity and save labor.

Steel Plantech has rich experience in supplying conventional ladle furnaces (LFs). We also developed a three-electrode simultaneous-control ladle furnace and named it the Single-Mast Furnace (SMF). With a simple mechanical configuration, the SMF enables short arc operation with a high power factor.

EBROSTM is a billet welding system with deburring machine to improve productivity by minimizing mis-rolling with less top biting and by reducing crop disposal, while rolling without billet gaps.

Ladle Furnaces (LFs)

Through the optimization of continuous casting and rolling processes, HDR and HDC processes are also streamlined significantly and even higher energy savings are achieved. A compact mill enables the smallest possible distance between stands to contribute to higher power savings, too. With the use of a high-speed block mill and controlled rolling process, high-quality products can be materialized.

Continuous caster can produce high-temperature and high-quality products which are fed directly to the rolling mill. This leads to more energy saving.

Rolling Mills/Flat ProductsThe only technology to realize excellenteconomic efficiency and high quality

Based on our superb technological capabilities and innovation, Steel Plantech supplies rolling mills for flat products and heavy plate shearing lines. Steel Plantech has unique technologies — SPEOSTM, Zoom-MillTM — to produce high-quality products while reducing the customer’s manufacturing costs.

Cold Rolling Mill

SPEOSTM Crown Rolls

For a broad range of steel strips, from the widest to narrowest, Steel Plantech has newly-developed roll crown tech-nology that can properly correct a strip crown and reduce the edge drop at the same time. This technology is most effective when applied to a 4-Hi mill.

A high-performance tandem cold mill with SPEOSTM rolls installed on every stand will produce high-quality products. A tandem cold mill can produce not only ordinary steel but also high-end steel products such as HSLA, HSS, DP, TRIP and magnetic steel sheets.

Reverse Cold Mill Zoom-MillTM Rolling Method

The reverse cold mill has enjoyed an outstanding reputation as a cold rolling mill that offers excellent cost-performance and satisfies high dimensional accuracy and flatness requirements.As SPEOSTM crown rolling is available as a standard feature, a reverse cold mill can be used as a Zoom-MillTM.

Zoom-MillTM is a new rolling method developed to minimize off gauge in reverse rolling by applying a leader strip and a spot welder.Higher yields can be achieved, along with improved productivity and reduced labor.Zoom MillTM can be installed in existing reverse rolling mills.
