History of Metal Processing. Iron’s beginnings date back many centuries. The first recorded use of iron was in 1800 BC by a people known as the Chalybes. The Chalybes wanted to make unparalleled weapons. At the time, bronze was primarily used but it wasn’t ideal as it was softer than iron. So the Chalybes would put iron ore into a hearth

The raw materials used in blast furnace smelting are mainly composed of iron ore, fuel (coke) and flux (limestone). Generally, smelting 1 ton of pig iron requires 1.5-2.0 tons of iron ore, 0.4-0.6 tons of coke, 0.2-0.4 tons of flux, a total of 2-3 tons of raw materials. In order to ensure the continuity of blast furnace production, it is
