How flexible is the black wire?
Iron is a relatively active metal, and more active than hydrogen. At present, most of our common iron wire is processed by drawing process and galvanizing, so as to ensure the stability of the structure of the iron wire and expand the scope of its use.
Black wire is relatively more flexible, even softness, consistent color. This material is mainly used in construction, mining, chemical industry, welding net, welding coat hanger, reprocessing, etc. After annealing, the wire becomes soft, flexibility increases, and the effect of building binding wire and reinforcing bar is better. Its packaging is the same as galvanized wire packaging, inside plastic outside hemp, inside plastic outside weaving, and first with a thin layer of plastic wire winding a circle, and then with hemp bag or woven bag will be winding! The purpose of annealing is to reduce hardness, improve machinability: eliminate residual stress, stabilize size, reduce deformation and crack tendency; Refine grain, adjust the structure and remove the defects. It's almost done and then it's packaged, and there's a very important part of the packaging process that you can't skip and that's the spraying. Spray oil is generally lubricating anti-rust oil or oil. It can ensure that the silk will not rust for a long time and the surface will be brighter. Iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in the dry air, and their demand in the market is relatively large. Wire must not be piled up on the work site of the other sundry, in the process of pickling, also want to make, protection in case of spill acid to themselves, protective goggles is indispensable, coil to should take put down gently, each other also must be strong and neat, at the same time, our company's product quality is good, the price is reasonable, by the general customers the consistent high praise.
