4.application:
black annealed wire is mainly used as industrial wire, construction wire, industrial bale tie wire and constructional tie wire, etc
5.technology
black annealed wire material is normally provided by the q195 type drawing rod into the black wire.the selected raw materials after 1000 degrees high temperature calcination keep enough time, then to appropriate cooling rate.the purpose is to reduce the hardness, improved machinability; elimination of residual stress, stable size, reduce the deformation and crack tendency; grain refinement, restructuring the organization, eliminate defects in the organization.
6.package:
in coils and from 0.7kgs/coil to 800kgs/coil each coil to be wrapped inside with pvc strips and outside with hessian cloth or inside with pvc strips and outside with weaving bag also can be made according to our customers' requirements.
