SARRALLE and KR Tec have joined forces to introduce KR MELT, a New Scrap Preheating Technology designed to optimize Electric Arc Furnace (EAF) operations. This cutting-edge system preheats scrap metal to approximately 700°C by efficiently harnessing the sensible heat from furnace off-gases.
 

Key Benefits of KR MELT Technology

KR MELT significantly reduces electric energy consumption, achieving energy savings of at least 100 kWh per ton compared to conventional EAF methods. This improved efficiency leads to lower operational costs by reducing electrode and refractory consumption. Additionally, the technology enhances productivity by over 20% due to shorter power-on and power-off times and continuous scrap charging capabilities.

The system operates within an airtight enclosure, minimizing heat loss and reducing dust emissions by 30%. These environmental benefits ensure compliance with stringent regulations while enhancing workplace safety by eliminating the risks associated with charging wet scrap.
 

From an operational standpoint, KR MELT enables continuous and independent scrap charging during furnace operation, eliminating the need to open the EAF roof. This significantly reduces heat loss and extends the lifespan of critical furnace components, such as the roof and delta. Moreover, maintenance requirements are minimized, as the system eliminates critical water-cooled mechanical parts, ensuring higher reliability and reduced downtime.
