Annealed black wire is a kind of soft annealed black wire made of low carbon steel by cold drawing, heating, constant temperature and heat preservation. Annealed black wire is composed of iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet is rolled into 6.5mm thick steel bars, also known as coils, and then put into the wire drawing device to draw into different diameter lines. And gradually reduce the diameter of the drawing plate, cooling, annealing, coating and other processing technology to make a variety of different specifications of annealed black wire.
The production of annealed black wire developed earlier because of its simple process and wide application. Annealed black wire or steel wire is a cold-working product of steel wire again, and the materials used are generally high quality low carbon steel or stainless steel. Usually annealed black wire through disk shell, pickling, washing, saponification, drying, drawing, annealing, cooling, pickling, washing, galvanized line, packaging and other procedures, in order to produce the production of annealed black wire (steel wire) iron ingot (steel ingot).
Annealed black wire has good elasticity and flexibility, and can control its hardness and softness in the annealing process. It is made of high quality annealed black wire, and is mainly used for binding wire and wire in construction industry. Annealed black wire and steel wire are generally produced by drawing process and galvanized treatment.
