Annealed wire is made of low carbon raw material, after drawing and annealing, soft and strong tensile strength. Finished products are coated with antirust oil, not easy to rust, can be bundled according to customer requirements, each bundle of 1-50Kg, or can be made into U-shaped wire, truncated wire, etc., internal plastic and external hemp packaging, mainly used as construction wire and so on.
General annealed wire manufacturers can be based on the user's special needs, according to industry standards to provide a variety of specifications of annealed wire. In the production process hot annealed wire has one more annealing process, so hot annealed wire corrosion resistance is stronger than electro-galvanized. Production process: coil - large drawing - annealing - medium drawing - annealing - galvanizing.
The main components of annealed wire are zinc, copper, cobalt, iron, nickel-carbon, etc., because the composition of each product is different, so there is a difference in the use of the product, but mainly in the construction industry, the annealed wire is softer and more flexible than ordinary wire, more enhanced flexibility, softness uniformity, and color consistency. There are two kinds of annealed wire preparation, respectively, first plated and then plated, first plated and then plated method. The products treated by the relevant procedures have good corrosion resistance.
Annealed wire manufacturers produce mainly 5#-38# (wire warp 0.17-4.5mm) than ordinary black iron wire is softer, uniform softness, more flexible, consistent color.
Annealed wire in use to ensure that its strength and toughness indicators, in particular, to prevent torsional cracking is the key to the production of spring iron wire, coil the intrinsic quality and surface quality are directly affecting the performance of the wire.
The quality of annealed wire depends on the quality of the annealing process, the annealing process to do a good job, the quality of the annealed wire is good, then the annealed wire annealed for the purpose of what exactly is it? Here we look at it together:
(1) Reduce the hardness of the wire, improve the cutting processability;
(2) Eliminate residual stress, stabilize the size, reduce deformation and cracking tendency;
(3) Refine the grain, adjust the organization, and eliminate organizational defects.
(4) Uniform material organization and composition, improve material properties or make organizational preparation for future heat treatment.
In production, the annealing process of annealing wire is widely used. According to the requirements of the workpiece annealed for different purposes, the annealing process specification has a variety of commonly used complete annealing, spheroidal annealing, and stress relief annealing.
As annealed wire after annealing this process, making it has good elasticity and flexibility, can be controlled in the annealing process of the degree of softness and hardness, therefore, the annealed wire is also quite wide range of uses, mainly used in the construction industry as binding wire and binding line.
Due to its strong flexibility and good plasticity, binding wire is widely used in various fields such as construction industry, handicrafts, woven wire mesh, product packaging and daily civilian use.
