Steel row nails is one of the many row nails series, because of its high strength, high hardness, can be nailed into concrete and other relatively hard materials, so it is called steel row nails.
Steel row nails have the following characteristics:
(1) The diameter of a single steel nail is 2.2mm, and the length is 18mm, 26mm, 38mm, 46mm, 50mm, 64mm and other different specifications.
(2) Steel nails must be 40 steel nails in a row, the top and side must be flat without warping.
(3) The nail row must have a certain rigidity and strength: hold one end, and the other end must not sink and break.
(4) The nail must be in close contact with the nail, and there must be no gap. The glue is evenly coated, no tumors and bubbles, and the glue boundary is limited to 10mm below the nail head.
Steel nail is a disk round wire (high, medium or low carbon steel) as the raw material, through the wire drawing machine several times to pull (cold drawing) to the wire diameter of the steel nail requirements, by the nailing machine to produce specifications of steel nails, quenched by the heat treatment furnace, and then polished by the polishing machine, and then galvanized equipment for electroplating, by manual glue, the steel nail into a row of qualified products.
After investigation, at present, the production equipment used by steel nail production enterprises is mainly:
① Nail making machine
② Wire drawing machine
③ Polishing machine
④ Knife sharpener
⑤ Rolling machine
⑥ Heat treatment furnace
⑦ Galvanizing equipment and tools used in manual nail row.
Steel row nails based on the above advantages, therefore, steel row nails have been widely used.
