The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.
The wire rod should be normalized or soxhlet processed, instead of spheroidal annealing for standard large ones. Soxhlet process is widely used in the heat treatment of the center, especially the products before drawing. Avoid decarbonization during heat treatment. After heat treatment, sulfuric acid or hydrochloric acid pickling is used to remove iron sheet. The coating (see smooth carrier) can be dip-lime, phosphating, borax treatment or copper plating.
Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When the galvanized wire out of light plating should be carried out light treatment, the galvanized wire bath to control the temperature. Now the quality level of galvanized wire on the market is not equal, galvanized wire is also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities.
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.
Pet cages can be used for indoor and outdoor pet houses. The dog cage is equipped with a fixed food basin and a drinking device, and the rubber pad of the pet cage with a bayonet on the four sides can be assembled. Can be splicing according to the size of the cage, shear, disassembly convenient, easy to clean, can solve the puppy in the ordinary cage pinched foot problem, prevent the puppy in the development of adverse reactions. The bulkhead of the pet cage is breathable and comfortable, which can be used as a heat shield for pets in summer. A puppy with small feet, not a foot, not a pinch.
The large hexagonal mesh is called the stone cage net. Stone cage net before delivery, must be folded into a simple surface, packed compressed after delivery. Then put it in the right position to open, and then the block diameter suitable stone into the cage, the cover is tight, and then the various stone cage net and the adjacent stone cage net tied up.
Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by customers, ensure that the metal wire achieves the role of rust and corrosion prevention, and meet the service life required by customers. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound inward to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test, which is decided according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.
From the plastic spraying, spraying blade gill net (pvc blade gill net, plastic blade gill net), also known as spraying blade barbed wire, spraying blade barbed wire is produced in the future, to rust treatment by the attack. Spray appearance treatment makes it have quite good anticorrosion ability, beautiful appearance, good waterproof effect, easy construction, economic and practical excellent characteristics. Spray blade thorn rope is a plastic powder spray on the product blade thorn rope of an appearance treatment method.
Hexagonal mesh is based on wire mesh prepared by metal wire, wire diameter of 0.3-2.0mm metal wire. Hexagonal mesh is a good choice for breeding cage, he is through hot dip galvanized or PVC coated plastic disposal, the structure is tightly combined with no bump and convex appearance. Keep chickens and ducks, isolate chicken and duck houses, and try to take care of poultry.
When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
