Ductile Iron

Pig iron is used in ductile iron production as a primary source of pure iron. It offers a number of unique advantages: pig iron contains low residual or harmful elements, has a consistent chemistry, promotes optimal slag conditions, and improves process control by providing consistent charge properties.Get price

Slag

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other Get price

Pig vs Scrap Iron

7/3/2017While pig iron may be the more economical input, technically and ecologically speaking, scrap iron is a far superior raw material. Products produced in modern foundries in developed countries never contain 100 percent pig iron, an intermediate product of the smelting of iron ore, and in fact they are normally produced with no pig iron at all.Get price

Lilleshall Company Priorslee Ironworks

Liquid slag that floats on top of the molten iron is removed. The slag is collected after the denser iron has been run out of a tap hole near the bottom of the furnace. Pig iron has a very high carbon content, along with silica and other constituents of dross, which makes it very brittle, and not useful directly as a material except for limited applications.Get price
