Specifications Introduction
Prestressed steel wire represents a hallmark of advanced steel engineering, being meticulously crafted from premium high-carbon steel plates. These wires undergo a transformative journey of acid washing, cold drawing, or stabilizing treatment post-phosphating, further classified by their production technology into cold-drawing and stress-eliminating variants. Depending on surface characteristics, they are categorized as plain, indented, or spiral rib steel wires. The cold drawing wire, renowned for its robustness, finds its direct application in prestressed concrete, enhancing structural integrity.
Raw Material Requirements
The production of prestressed concrete demands exceptional raw materials, specifically high-quality carbon steel wire rods such as SWRH77B or SWRH82B. These wire rods are critically evaluated on parameters including size, shape, weight, and permissible deviations. Further essential criteria comprise grade specifications, precise chemical composition, smelting techniques, delivery condition, mechanical robustness, decarburization depth, microstructural integrity, surface finish, and any bespoke requirements tailored to specific engineering needs.
Employing the cutting-edge Sterem technology, the cooling process is expertly controlled to achieve an impressive Sotenization rate exceeding 85%, ensuring optimal performance. The resulting coils seamlessly align with the stringent production demands of prestressed concrete steel wire and strands, reliably meeting industry standards.
Standards of Steel Wire for Prestressed Concrete
The prevailing standards are meticulously outlined in GB/T5223-2014, providing comprehensive guidelines. 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 versatile application of prestressed steel wire extends to constructing resilient single-story and multi-story edifices, enhancing the durability and safety of highway and railway bridges, and fortifying infrastructure such as sleepers, electric poles, and pressure water conduits. This steel wire also lends its strength to storage tanks and water towers, and finds critical utilization in state-of-the-art high-rise buildings, subterranean structures, towering edifices, hydraulic facilities, marine and airport constructions, and nuclear power plant pressure vessels. It supports a myriad of industries, fulfilling the demands of super-tall, super-span, super-volume, and super-large area projects, adeptly accommodating various shapes and specialized structural engineering functions.
