Specifications Introduction
Prestressed steel wire represents an exceptional category of steel wires, fashioned from top-tier high-carbon steel plates. These undergo meticulous processes such as acid washing, cold drawing, or stabilization post-phosphating, ensuring unparalleled quality. The intricate manufacturing techniques delineate two distinct types: cold-drawing steel wire, prized for its immediate applicability in prestressed concrete, and stress-eliminating steel wire, renowned for its resilience. Furthermore, based on surface texture, these wires are classified into plain, indentation, and spiral rib varieties, each serving specific construction needs.
Raw Material Requirements
The foundation of premium prestressed concrete lies in the exceptional carbon steel wire rods, specifically the SWRH77B and SWRH82B variants. These materials are stringently assessed for diverse attributes, including dimensional precision, geometric silhouette, mass and permissible fluctuations, classification, chemical composition, metallurgical processes, delivery condition, mechanical performance, decarburization layers, microstructural integrity, surface excellence, and unique specifications, ensuring they meet the highest standards.
Employing cutting-edge Sterem technology, the cooling process is expertly managed to secure an impressive Sotenization rate exceeding 85%. The coils produced under this advanced methodology effortlessly align with the rigorous production standards demanded by prestressed concrete steel wire and strand applications.
Standards of Steel Wire for Prestressed Concrete
The current 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
Prestressed concrete steel wire boasts an extensive application spectrum, from reinforcing single-story and multi-level buildings to underpinning vast highway and railway bridges, sleepers, electric poles, and pressure water conduits. It also fortifies storage facilities, water towers, and evolves to support modern marvels like high-rise and subterranean structures. Additionally, it is pivotal in crafting hydraulic, marine, and aviation edifices, including runways and terminal buildings, as well as securing pressure vessels in nuclear facilities. This wire's versatility excels in diverse industries, accommodating super-tall, super-spanning, and super-massive constructions, as well as unique, multi-functional architectural endeavors.
