Large roll galvanized wire is processed from high quality low carbon steel wire rod. Each wire rod rolled by continuous rolling mill is not less than 200kg, but 15% of the number of plates in each batch is allowed to be composed of two, of which the weight of each rod is not less than 80kg, and 4% of the number of plates in each batch is allowed, and the mass of its single wire rod is less than 200kg, but not less than 40kg. Each rod rolled by semicontinuous mill shall not be less than 60kg, and each batch shall be allowed to have 5% disk nitrogen. The mass of the rod shall not be less than 60kg, but not less than 30kg.

Moderate rates of foam formation may be harmless. The presence of small, homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of excessive solid particles can cause an explosion.

After annealing, the extension rate of galvanized wire is increased, making the product more soft and increasing the scope of application of galvanized wire. After electric galvanized hot galvanized, electroplated copper and other widely used screen production. Building reinforcement binding with galvanized wire mesh braided with the first after plating, plating and other methods, after treatment of galvanized wire mesh or steel wire mesh, has good corrosion resistance, oxidation resistance characteristics, can be used in construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries reinforcement, protection and heat preservation.

Now large roll galvanized wire in our life the use of more and more, to galvanized wire products bring a great market, galvanized wire products are more and more types. The surface coating of good quality galvanized wire is continuous and smooth. When the plating parts are installed and combined, there can be no flow hanging, slag or drop remaining, and no surface defects such as iron exposure. Good quality galvanized wire, coating must be uniform, roughly uniform in copper sulfate solution soaking five times without exposing iron. And with hammering test does not bulge, do not fall off. This is a good galvanized wire should have characteristics.

Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.

Welding net is generally used in construction, breeding chicken and pigeon rabbit cage, balcony protection, machine cover, flower guardrail and so on. According to the welding aperture, wire diameter is different, the use of welding net products are different, such as: the use of insulation wall welding net on housing construction, agricultural circle corn mesh welding net, the use of breeding chicken, mink and other breeding welding net. So what should be paid attention to when choosing the welding net? Mainly in the following three aspects
