Products Overview
The Feeding System for EAF & SAF is a critical auxiliary system in electric arc furnace and submerged arc furnace smelting operations. It is designed to safely, stably, and controllably charge raw materials-such as scrap steel, ores, coke, reductants, and alloying materials-into the furnace in accordance with defined process requirements.
In metallurgical production, the feeding system is not merely a material conveying device. It has a direct impact on furnace thermal balance, smelting rhythm, and overall operational stability, and serves as an essential component for achieving mechanized and automated production.
