Is high temperature pig iron poisonous?
Iron carbon content of 2.11%-6.67% and impurities than non ferrous iron carbon alloy iron impurities are mainly silicon, sulfur, manganese, phosphorus and iron hard brittle lack of toughness almost no plastic deformation ability to forging, rolling, drawing, machining form containing silicon and high iron (gray) casting and cutting performance
High temperature iron oxide iron impurity elements, mainly silicon, sulfur, manganese, phosphorus and other high temperature oxidation, will produce oxides, sulfur and phosphorus oxides toxicity, high temperature iron oxide toxin
Iron directly from the blast furnace production of crude iron according to their use of iron and steel smelting casting iron two iron and steel smelting iron cast iron is used casting forging, referred to as CRC metamorphism, spheroidization etc. change the internal structure and improve casting iron white iron, the mechanical properties of gray cast iron, malleable cast iron, ductile cast iron, special cast iron etc.
