The wire factory introduced that the wire diameter should conform to the contract, the zinc quantity should be inspected to meet the contract requirements, and the tensile strength should be inspected, and the factory should provide the corresponding inspection report. Weigh each coil of wire of different specifications, not less than the coil weight specified in the contract, and record the value. Contact detection. Each coil of wire does not produce contacts. If there are contacts, each coil should not exceed three contacts. The surface of each contact shall be smooth, and the wire shall not be pulled off from the contact, in line with the packaging requirements of customers.
The quantity should be the same as the contract, cold wire drawing, carefully record the product quantity of each specification and packing method. If there is a label, check whether the label is correct and take a photo to confirm. Packing: each coil of iron wire is fastened with galvanized packing belt, and then tied with very strong transparent plastic bags. The coated iron wire is wrapped with white woven cloth on the outside, and the galvanized iron wire is wrapped with green woven cloth on the outside to ensure that the packing will not be loosened during transportation. One end of the wire must be clearly marked and the other end must be left on the outer layer to facilitate the connection of other wires.
Ask the factory to provide the corresponding quality inspection report before packing. Cold wire drawing is a kind of material often used in our life, especially in the construction of buildings. Cold wire drawing in building materials used more, detection standards are not the same. Cold wire drawing strength is high, can be used in many aspects, cold wire drawing manufacturers, with much is the prestressed tendon. Where plasticity is not required, only strength is required, such steel can be used.
Process: the use of high quality low carbon steel rod processing, is the use of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanizing, cooling and other processes processed. Relative hot dip galvanizing, electric galvanizing production cost is lower. Application range of hot dip galvanizing: because of the thicker coating, 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.
