  • The tensile strength of steel wire is high and the hardness is high. In the flattening process, the longitudinal movement resistance of steel wire per unit volume increases and the elongation decreases. The steel wire unit volume will move to the lateral resistance smaller, the width of the increase. On the contrary, the wire is easy to extend lengthwise, and its width decreases. This is the production of high steel wire hardness is easy to wide, small hardness, easy to stretch out of wide reasons. If the tensile strength deviation of steel wire is large, the hardness uniformity of steel wire strip is poor, the width difference of the billet rolled into large, will seriously affect the quality of the billet.

  • In sulfur dioxide, hydrogen sulfide and Marine atmosphere, zinc corrosion resistance is poor, especially in the high temperature and high humidity atmosphere containing organic acid, galvanized wire galvanized layer is easy to be corroded. The surface of galvanized wire galvanized layer uniformity and color of galvanized wire, good quality galvanized wire surface galvanized layer uniformity, zinc adhesion is good, and the color is white, no leakage plating and rust points.

  • According to the different requirements of the industry, different weights of alloy ingots are put in the smelting furnace according to the standard, such as weaving, Ming, paper, lang, silicon, etc., and the data out of this smelting is called gold ore iron. Iron has gray iron, white iron and the above-mentioned gold, they have different characteristics, so in the industry according to their different characteristics to transport and selection. For example, in gray iron, its carbon exists in iron ore in graphite condition, the crack is often gray, soft and strong, simple filtering, suitable for casting.
