Advancing the Standard of High-Efficiency Steelmaking<\/h2>\n

The Electric Arc Furnace (EAF)<\/strong> is the premier equipment for modern steel production, offering unmatched flexibility and energy efficiency in recycling iron and steel scrap. As a high-capacity arc furnace<\/strong>, it utilizes high-intensity electrical arcs to melt scrap metal and primary iron sources. At HANI<\/strong>, we have focused our research on ultra-high power (UHP) technology, delivering EAF steelmaking<\/strong> solutions with power ratings up to 1500 KVA per ton of liquid steel. Our scrap melting<\/strong> units are engineered to reduce tap-to-tap times to less than 45 minutes, significantly increasing the annual productivity of the steel plant while maintaining the highest alloy quality.<\/p>\n

HANI’s Electric Arc Furnace (EAF)<\/strong> technology incorporates advanced raw material pre-heating, which can reduce energy consumption to below 300 kWh per ton of steel. Our arc furnace<\/strong> units are designed with a robust furnace shell, high-efficiency electrode management, and automated spray cooling systems. When combined with our secondary refining equipment like LF and VD, the HANI EAF steelmaking<\/strong> system provides a comprehensive solution for producing high-grade carbon steels, alloy steels, and stainless steels. As a world-class provider of scrap melting<\/strong> technology, HANI ensures that every Electric Arc Furnace (EAF)<\/strong> meets the rigorous demands of the global steel industry.<\/p>\n<\/div>\n

The Process of Scrap Melting and Refining<\/h2>\n

The EAF steelmaking<\/strong> process involves the rapid conversion of electrical energy into thermal energy via the electric arc. In an Electric Arc Furnace (EAF)<\/strong>, the intense heat of the arc (exceeding 3000\u00b0C) melts the scrap metal charge. HANI’s arc furnace<\/strong> technology optimizes the melting kinetics by utilizing oxygen-carbon lances for chemical energy input and slag foaming. This scrap melting<\/strong> route ensures that the phosphorus and sulfur levels are effectively managed in the primary stage.<\/p>\n

Thermodynamic Reactions in EAF:<\/p>\n

1. [P] + [O] \u2192 (P2<\/sub>O5<\/sub>) (Dephosphorization in basic slag)
\n2. [C] + [O] \u2192 CO(g) (Slag Foaming & Energy Input)
\n3. Fe + 1\/2 O2<\/sub> \u2192 FeO (Initial Oxidation)<\/p>\n<\/div>\n

Scientific facts from HANI<\/strong>‘s engineering research demonstrate that the use of a micro-mist spray system and intelligent power control in our Electric Arc Furnace (EAF)<\/strong> significantly stabilizes the interior temperature field. This improves the recovery efficiency of the arc furnace<\/strong> and ensures the purity of the produced steel. As a leader in EAF steelmaking<\/strong>, HANI provides scrap melting<\/strong> solutions that are not only highly productive but also meet the strictest environmental standards for gas emissions.<\/p>\n<\/div>\n
