Cutting methods are available: 1. machining, 2. air gouging, 3. plasma cutting, and breaking iron like broken furnace charges. Wire cutting is also a method, but if it is a casting, it is not good to use wire cutting because of metal surface and non-metallic material inside.
According to the different form of carbon in pig iron, it can be divided into several kinds, such as steelmaking pig iron, casting pig iron and nodular cast iron. Pig iron performance: pig iron is hard, wear-resisting, casting good, but pig iron is crisp, can not forge.
Pig iron is an alloy of iron and carbon carbon content more than 2%, pig iron carbon content is generally in 2.5%--4%, including C, SI, and Mn, S, P and other elements, is the use of iron ores in blast furnace smelting products.
