The hearth is surrounded by a roof and walls of refractory ...
WhatsApp: +86 18838072829About Making steel Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route.
WhatsApp: +86 18838072829The first step in this process is crushing and grinding the ore to a fine powder. This powdered ore is then subjected to a process called magnetic separation, where magnets are used to separate the iron particles from other minerals present in the ore. This helps in purifying the iron ore and increasing its iron content.
