The wire factory introduces that the wire diameter of the wire should conform to the contract, check whether the zinc content meets the contract requirements, test the tensile strength, and ask the factory to provide the corresponding inspection report. Weigh the weight of single coil wire of different specifications, not less than the coil weight required by the contract, and record the value. Contact detection. Each reel of wire does not produce contacts, if any, a maximum of three contacts per reel. The surface treatment of each contact should be smooth, the wire should not be pulled from the contact, and meet the customer’s packing requirements.
The quantity should be the same as the contract, cold drawing, carefully record the quantity of each specification and packing method. Check whether the label is correct, take a photo to confirm. Packing: each coil of iron wire should be fastened with galvanized packing tape, and then tied tightly with a very strong transparent plastic bag. The plastic coated iron wire should be wrapped tightly with white woven cloth, and the galvanized iron wire should be wrapped tightly with green woven cloth, so as to ensure that the packing will not be loosened during the transportation. One end of the wire must be clearly marked and the other end left on the outer layer so that other wires can be connected.
Ask the factory to provide the corresponding quality inspection report before packing. Cold drawing wire is a kind of material often used in our life, especially in the construction of buildings. Cold drawing in building materials used more, the detection standards are not the same. Cold drawing strength is high, can be used in many aspects, cold drawing manufacturers, with much is the prestressed tendon. Such steel may be used where plasticity is not required, only strength is required.
Process: The use of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanizing, cooling and other process processing. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower. Application scope of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment.
