Black iron wire, annealed wire production process

Everybody is not strange for steel wire, this is because it is very extensive application in the life, such as the existence of the wire mesh we often see it but you know production process of steel wire.

Wire should have high tensile strength, elastic limit, toughness and fatigue strength, and resistance to shock and vibration. To ensure the strength and toughness index, especially to prevent reverse the generation of crack is the key to the production of spring steel wire. The immanent quality of wire rod and surface quality are directly affect the performance of steel wire. Carbon spring steel wire with high carbon high quality carbon structural steel or carbon tool steel wire rod production, must be based on the purposes of spring strictly control its chemical composition, gas content and nonmetallic inclusions. In order to reduce the surface defects and decarburization layer, in the production of wire rod for surface grinding of steel, peeling when necessary. Wire rod to be normalizing or sorbite, specifications of ball annealing instead. Especially among the finished product before heat treatment widely used pull sorbite.

When the installation of the steel wire mesh: build by laying bricks or stones wall embedded bar as a fixed, fixed wire rack of polystyrene (abdomen) non-penetrating type, cut wire rack of polystyrene according to design requirements, puts the fish men's good metal bracket, pressure bar, will be embedded in the steel and metal bracket on the steel bending compression steel wire rack of polystyrene.

And then there are the wire mesh plate cutting, according to the requirements of building energy efficiency design, the size of the wire mesh precision is very important, so the volume of the good later can fragments of the wire mesh with wire cut open, and then use electric heating wire or dense tooth saws will cut of polystyrene.
