Specifications Introduction
Prestressed steel wire is the epitome of precision engineering, crafted meticulously from premium high-carbon steel plates. The process encompasses acid washing and cold drawing, followed by a stable treatment post-phosphating. This versatile wire comes in two primary forms based on production techniques: the resilient cold-drawing steel wire and the stress-relieved variant. The surface texture further diversifies it into plain, indentation, and spiral rib steel wire. Notably, the cold-drawing wire stands ready for immediate use in prestressed concrete applications.
Raw Material Requirements
At the heart of prestressed concrete lies the high-quality carbon steel wire rods, specifically SWRH77B or SWRH82B. These rods must adhere to stringent criteria concerning size, shape, weight, and allowable deviations. Additional requisites include grading, chemical composition, smelting technique, state upon delivery, mechanical properties, decarbonization layer, microstructure integrity, surface finish, and any bespoke specifications.
Innovative Sterem technology governs the cooling process, ensuring an impressive 85% Sotenization rate. By adhering strictly to standard procedures, the resulting coils seamlessly align with the production demands for both prestressed concrete steel wire and steel strand.
Standards of Steel Wire for Prestressed Concrete
The present regulatory benchmarks are encapsulated in GB/T5223-2014 Prestressed concrete steel wire, according to renowned international standards such as 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, and others.
Applications for the Reinforcement of Concrete Constructions
The scope of steel wire for prestressed concrete is vast, spanning the construction of single and multi-story buildings, robust highway and railway bridges, durable sleepers, electric poles, pressure water conduits, capacious storage tanks, and towering water towers. The potential extends to contemporary high-rise and subterranean structures, intricate hydraulic and marine edifices, expansive airport facilities, including runways and terminals, as well as the critical pressure vessels of nuclear power stations. This product serves diverse sectors, supporting super-tall, super-span, super-volume, and super area-heavy structures, addressing unique functional needs in structural engineering.
