First of all, iron ore, yellow ore and carbon are collected to serve as a raw material for steel rods manufacturing. After that, the raw material is melted in a melting slit, where it is heated to a temperature in range of 1300-1500 °C. The melted mass is then transferred to a smelting cabin to undergo refinement.
