Product Description
Ramming Mix For Electric Arc Furnace
Crafted through an advanced synthetic process involving meticulous palletizing and high-temperature burning, this exceptional product ensures the formation of a solid, fully sintered layer when exposed to high temperatures. This premium material is indispensable for expertly ramming the bottoms and slopes of a wide array of electric furnaces, including Ultra High Power (UHP) electric furnaces, High Power (HP) electric furnaces, Regular Power (RP) electric furnaces, Direct Current (DC) electric furnaces, and Open Hearth Furnaces (OHF).
