Rope production process raw materials: Here that means the raw materials have been drawing rope acid, phosphate, peel, blooming, one or more times during the pull-out wire rope specifications, changing its molecular mechanism to reach the target diameter A process means. Raw materials are 0.14 ~ 10.00mm diameter of ferrous and non-ferrous metals was 0.01 ~ 16.00mm. Pickling: acid wash process with surface rust, and rolled leather rope raw materials in the production process, also known as rope peel, mainly the high line of oxide stripping to avoid rust and other impurities affect blooming, damaged wire drawing dies. Phosphate: popular to say that the material is immersed in a phosphate solution rope length, so that the surface layer of the process to obtain a water-insoluble phosphate film. To some extent, to prevent corrosion. Rope production process 2 cogging: various shaped through-hole wire drawing die center, round, square, octagonal, or other special shapes. When the metal forced through the die hole size, shape are changed. Cold Roberts: ordinary round, let it pass than its diameter smaller Kong Zhongjiang pull off the line, the round will be smaller in diameter, the length will stretch, repeat this process, the bar will further smaller. Produce this plastic deformation of steel hardness will increase after the plastic will basically disappear. Plastic is not required, only the strength requirements of the occasion, such as steel can be used. Tempering: Because the molecular structure of the wire has been destroyed, only tempered steel wire again to restore the interior of the structure. In order to re-drawing, so easy to break, but we want to be able to pull strength. Strength is what we mean tensile strength. Strength is La Sila out, not out of the heat treatment. This is the biggest difference between the rope and the machining process of the craft. General strength: 1470N / mm2,1570N / mm2,1670N / mm2 wire rope, 1770N / mm2,1870N / mm2,1960N / mm2 higher the intensity, the stronger the pull rope 14mm, but toughness worse. Therefore, we should choose the appropriate selection of the rope strength. Not blindly high strength. High tensile strength steel wire rope is strong, but in terms of durability and flexibility is relatively weak.
