Cold wire drawing is a kind of cold working of metal. The raw material is wire rod, which is produced by the process of peeling and galvanizing. Galvanized cold drawing is more used in building materials, and its testing standards are different, and the strength of cold drawing is relatively high. Because of the high strength of steel, it plays a very important role in construction, saving construction steel in building materials, and reducing the engineering cost, and also playing a very important role in the structure of concrete.
Cold wire drawing is mainly used in the production of hardened low carbon steel wire, the use of steel bars with a diameter of 8 mm to carry out a fixed role in the development of the construction industry has played a role in promoting the development of the construction industry, and the application is more widely. The bonding and anchoring performance between cold drawing wire and concrete is good. Used in the component, the phenomenon of cracking in the anchoring area of the component and the damage caused by the slip of the steel wire is fundamentally eliminated, and the bearing capacity and anti-cracking ability of the end of the component are improved.
In reinforced concrete structures, the crack width of cold-drawn wire is also smaller than that of circular steel bars and even that of hot-rolled thread bars. Therefore, cold wire drawing is relatively popular in the construction industry. Water washing In the production process, after each process are washed two or more times, and ensure that clean. Water quality requirements for preparation of galvanized and passivation tank water should be deionized water or distilled water, and other water can be used domestic tap water.
Tank analysis All tank fluids should be analyzed regularly, and not less than once a week, with complete records. Filtration galvanized should be continuous filtration or regular filtration, regular filtration not less than once a month, complete records. Production records The processing date, name, drawing number, quantity, dehydrogenation temperature and time of the parts should be recorded during the production process. Before production, the operator should check whether the relevant production equipment has a qualification label or certificate, and it can be used within the validity period after verification.
