Hardware Knowledge Base: "Annealing Wire"

Annealing wire is a kind of soft iron wire product made of low carbon steel cold drawing, heating, constant temperature, heat preservation and other processes. Iron wire varies in composition depending on its purpose. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet is rolled into a 6.5mm thick steel bar, which is a wire rod, and then put into a wire drawing device to draw into different diameter wire, and gradually reduce the bore diameter of the wire drawing disc for cooling, annealing, coating and other processing Process made into a variety of different specifications of wire.

Iron wire production has been developed earlier because of its simple process and wide application. Iron wire or steel wire (corresponding to the "wire mesh enterprise") is a second cold-worked product of steel wire rods. The materials used are generally selected from high-quality low-carbon steel or stainless steel. Usually, the iron wire (steel wire) can be produced through several procedures such as shelling, pickling, washing, saponification, drying, drawing, annealing, cooling, pickling, washing, galvanizing, and packaging. Iron ingots (steel ingots).

At present, wire drawing and wire drawing are generally used in wire drawing and galvanizing. In 1976, the galvanized iron wire factory in Guangzhou was the first to apply the new technology of electrolytic pickling, high pressure flushing, and card drying to successfully produce continuous drawing wire, making the drawing process from intermittent production to continuous production, and weakening the labor intensity. Reduced metal consumption. At that time, the domestic wire factory has been able to produce steel wire, spoke wire, umbrella wire, spring wire, bicycle saddle spring wire and other products. In the 1980s, stapled hot-dipped low-carbon steel wire, fan net shroud steel wire, carbon structural steel wire, and bed surface wire were also introduced.

The weaving of barbed wire is preceded by plated and plated first and then woven. After processing, the barbed wire or steel mesh has good corrosion and oxidation resistance and can be used in construction, petroleum, chemical industry, breeding, garden protection and food processing. Other industries such as reinforcement, protection and insulation.

For example, welded wire meshes that are widely used in industries such as industry, agriculture, breeding, construction, transportation, and mining are made of high-quality low-carbon iron wire and then cold-plated (plated), hot-dipped, PVC-coated, and other surfaces. Through passivation and plasticization, the metal mesh produced has a flat mesh surface, uniform mesh, and a firm solder joint, which is characterized by stability, corrosion resistance, and good corrosion resistance. The stainless steel welded wire mesh is made of high quality stainless steel wire, such as machine guards, animal livestock fences, flower and wood fences, window guards, access fences, poultry cages, and home office food baskets, paper baskets, and decorative articles. More acid, alkali, welding firm, beautiful and so on.
