Wire is the smallest section size of hot rolled steel, generally refers to the diameter of 5-60mm hot rolled round steel or equivalent to the section of the special-shaped steel, because of the coil state delivery, collectively referred to wire or wire rod.
Classification of wire
1. According to the production side classification: divided into high-speed wire (high wire) and ordinary wire (general line) two kinds.
2. According to the chemical composition classification: divided into low carbon wire (called flexible wire), high carbon wire (hard wire), and low alloy and alloy steel wire (construction), stainless steel wire and special steel wire (bearings, tools, precision, etc.) several categories;
3. According to the material classification: ordinary low carbon steel hot rolled disk bar, high quality carbon steel wire rod, carbon electrode wire rod, quenching and tempering thread wire rod, wire rope wire rod, piano wire rod and stainless steel wire rod, etc.
4. Classify according to steel distribution catalogue: casting ordinary low carbon steel wire casting, welding wire casting, blasting wire casting, tempering thread casting, high quality wire casting.
Wire rod general production using ordinary mill and high – speed mill production. Generally, the wire mill with rolling speed greater than 40m/s is called high-speed wire mill, and the rolled wire is called high wire.
Wire is different because of its section shape, computational method is different, its main section shape is circular and screw model.
Wire is one of the steel varieties with very large dosage, general wire output accounts for 8~10% of total steel output, and our country accounts for more than 20%. Wire utility spreads all over each branch of national economy, except be used as building directly outside, deep processing product utility is more extensive.
Ordinary wire is mainly used for construction, wire drawing, packaging, welding rod and manufacturing bolts, nuts, rivets and so on.
High quality wire can be used by reprocessing, such as through pulling into all kinds of specifications steel wire, then twist made of steel wire rope, braided into steel screen and winding molding and heat treatment into spring; After hot, cold forging into rivets and cold forging and rolling into bolts, screws, etc.; After cutting into heat treatment into mechanical parts or tools, etc.
All the time, fastener wire has carbon steel, alloy steel, stainless steel and other materials, fastener metal raw materials are constantly developing and breakthrough, better quality raw materials wire is our eternal pursuit.
