Steel - Open-hearth steelmaking | Britannica

This permits the charging of all furnaces by the same charging machine, crane, and rail system. Bulk materials, such as scrap, cold blast-furnace iron, ore, limestone, coke, and alloying agents, are charged through the furnace doors in small boxes of one- to two-cubic-metre capacity. The boxes are brought to the OHF on small railroad buggies .
