Specifications Introduction
Prestressed steel wire boasts superior craftsmanship as it is meticulously produced from premium high-carbon steel plates. The process involves thorough acid washing, precise cold drawing, and stable post-phosphating treatment. This remarkable steel wire is categorized by production technique into cold-drawing steel wire and stress-eliminating steel wire. Surface conditions further classify it into plain steel wire, indentation steel wire, and spiral rib steel wire. Cold drawing wire, known for its exceptional performance, is directly used for prestressed concrete upon post-cold drawing.
Raw Material Requirements
The backbone of prestressed concrete production lies in the superior quality of high-carbon steel wire rods, specifically SWRH77B or SWRH82B. These wire rods must meet stringent requirements in size, shape, weight, and allowable deviations, alongside grade and chemical composition, smelting method, delivery state, and mechanical properties. Additional considerations include decarbonization layer, microstructure, surface quality, and any special requirements, ensuring unparalleled reliability and performance.
Cooling is expertly controlled using advanced Sterem technology to achieve a staggering Sotenization rate of over 85%. This meticulous process ensures that coils meet the exacting standards required for prestressed concrete steel wire and steel strand production, consistently satisfying industry demands.
Standards of Steel Wire for Prestressed Concrete
The prevailing standards are GB/T5223-2014, setting the benchmark for quality.Prestressed concretesteel wire, according toASTM 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
Steel wire for prestressed concrete is pivotal in the construction of single-story and multi-story houses, highways, and railway bridges, sleepers, and electric poles. It also fortifies pressure water pipes, storage tanks, and water towers. Its remarkable versatility extends to contemporary high-rise buildings, subterranean structures, hydraulic edifices, marine constructions, airport infrastructures like runways and terminals, and the pressure vessels of nuclear power plants. The steel wire serves a multitude of industries, supporting super-tall, super-span, super-volume, super-large area, and heavy load structures with diverse shapes and complex engineering functions.
