Specifications Introduction
Prestressed steel wire is an exceptional category of steel wire crafted from high-quality high-carbon steel plates. This sophisticated process involves acid washing, followed by cold drawing or stabilization post-phosphating. Based on varied production techniques, these wires are classified into two distinguished types: cold-drawing steel wire and stress-eliminating steel wire. Additionally, depending on the surface finish, they can be categorized into plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire serves as an integral component directly used for prestressed concrete applications after undergoing the cold drawing process.
Raw Material Requirements
The cornerstone of manufacturing prestressed concrete lies in utilizing high-quality carbon steel wire rods such as SWRH77B or SWRH82B. These wire rods must adhere to stringent requirements encompassing size, shape, weight, and permissible deviations. Essential attributes also include grade, precise chemical composition, smelting techniques, state of delivery, mechanical properties, decarbonization layer, micro-structure, surface quality, and any bespoke specifications or requirements.
Cooling is meticulously regulated using advanced Sterem technology, ensuring an impressive Sotenization rate of over 85%. Typically, the coils produced through this meticulous process are more than adequate to meet the rigorous production demands of prestressed concrete steel wire and steel strand.
Standards of Steel Wire for Prestressed Concrete
The prevailing standards are GB/T5223-2014 Prestressed concrete steel wire, according to ASTM A421-16, ASTM A881/A881M -2005, BS5896-2012, EN10138-2:2009, GOST 7348-81, TU U27.3-136-004-2003, DSTU ISO 6934-2, GOST 7348-81, DSTU ISO 6934 - 2, ABNT NBR 7482:2008, etc.
Applications for the Reinforcement of Concrete Constructions
The diverse application spectrum of steel wire for prestressed concrete encompasses a wide array of construction projects. This includes single-story and multi-story structures, as well as complex highway and railway bridges. The steel wire is also fundamental in the construction of sleepers, electric poles, pressurized water pipes, storage silos, and water towers. Its utility extends to modern engineering marvels such as high-rise buildings, subterranean constructions, towering structures, hydraulic edifices, maritime installations, and expansive airport buildings including runways and terminal complexes. It is a vital component in the infrastructure of nuclear power plants, serving in pressure vessels. The material is indispensable in fields demanding super-tall, expansive spans, colossal volumes, extensive areas, and extraordinary loads, supporting a myriad of structural designs with varying purposes and engineering applications.
