  • In the calculation process of 12*14 specifications of barbed rope, it can not be calculated according to the above calculation formula, because first of all, two specifications of raw materials are used, the thinner the wire diameter, the higher the processing cost. Generally speaking, a kilogram of 12*14 barbed rope can reach about 7.5 meters, and the ratio of warp wire to barbed rope cannot be calculated according to the traditional ratio of 7 to 3. The specific use of how much wire and silk need to go through a series of professional measurement but also increase the loss of raw materials and other factors to calculate. Thorn rope factory will also according to customer needs to calculate the reasonable amount of customer use.

  • Cooling can be in the groove close row of thin wall plastic pipe, through the flow of tap water for cooling, can also be used as a temperature control device titanium pipe. In the process of electroplating galvanized wire, it is necessary to stir the plating solution to obtain the composite coating with particles dispersing in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc.

  • Traditional barbed wire is woven into wire, with the development of the economy, the rapid rise of all walks of life, the limitations of the use of traditional barbed wire gradually exposed, such as: aquaculture, to the chicken circle a cage can not be too dense, the wire can not be too thick, woven mesh wire once the mesh over the surface of the net will become soft. We also have the solutions: 1, rolling the straight wire into a wavy shape, but still not enough to feed chickens with mesh can only stretch out the chicken beak can not feed! 2, is electric welding mesh, with the current to the longitude and latitude of the wire spot welding together, mesh do more than most is not restricted.

  • The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.
