1, stress relief before plating where the maximum tensile strength is greater than 1034Mpa key and important parts before plating should be at 200±10℃ stress relief for more than 1 hours, carburizing or surface quenching parts should be at 140±10℃ stress relief for more than 5 hours.

Use in daily life does not need to carry out maintenance and maintenance, save a lot of time, but also save maintenance and maintenance costs. The annealed wire has good stability and corrosion resistance, which greatly prolongs its service life. There are many kinds, which can be selected according to different uses. The device for making anneal wire is simple, which improves the utilization rate of the device. The material properties of annealed wire can meet different processing requirements.

The distance between the adjacent two thorn rope installation do not know whether you have noticed? Careful observation can find that its spacing is not the same, the thorn rope factory for customer consultation when asking the installation height of the reason.

The surface coating of galvanized wire can be seen whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire. High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer, we can generally judge the quality of galvanized wire.

Many electrogalvanized wire diameter products are formed by wire drawing, wire drawing is a kind of processing technology, can make the product reach the required shape and meet the standard mechanical properties. Cold wire drawing is carried out at recrystallization temperature, hot wire drawing is carried out at crystallization temperature, warm wire drawing is drawn at higher than room temperature and lower than crystallization temperature. Cold drawing is a common drawing method.

In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.

Hot dip galvanized coating is also relatively thick, but there is an uneven situation, for example, the thickness of the thin is only 45 microns, thick can reach 300 microns or even thicker, the color of this product is relatively dark. There is also a lot of zinc consumed in the production process. Zinc will form an infiltration layer with the metal. Its advantage is that it has good corrosion resistance. Electrogalvanizing, it is through the plating tank in the zinc one-way plating on the outside of the metal products, this way of making products is relatively slow, but its thickness is more uniform.
