Excuse me. What kind of pig iron into wrought iron process. Urgent need!
Soft wrought iron, good plasticity, easy deformation, strength and hardness were lower, not widely used; iron carbon, hard and brittle. (Q235) belong to the common carbon structural steel, generally used as building materials and unimportant mechanical structure materials, when used, the general department for heat treatment.
Comparison of pure iron with iron and refined. The carbon content below 0.02%, also called the wrought iron. Iron is very soft, good ductility, can pull into a wire, easily forged and welded. Generally less than 0.02% carbon content called wrought iron or iron, content in 0.02-2.11% steel, called iron content in 2.11-6.69%.
Besides, this kind of steel can not be heat treated, and the low carbon steel has poor heat treatment performance. If surface mechanical properties must be improved, surface carburizing is necessary and surface hardening is performed. Ordinary structural carbon steel, this kind of steel is not very strict with the chemical composition, the content of carbon and manganese can be changed in a large range, and the mechanical properties are not very good.
