Scrap continous feeding through EAF 5º hole

This material is charging into uncovered hoppers that feed special inclined conveyors to transport the proler until the next stage, an intermediate storage hopper. The last connection between this external storage hopper and the EAF is made by a belt that conveys the proler towards the inside of the Meltshop, just until the point of being poured into the EAF through the 5th hole.
