Specifications Introduction
Prestressed steel wire represents the pinnacle of innovation in steel wire manufacturing, crafted meticulously from premium-grade high-carbon steel plates. These plates undergo rigorous processes like acid washing, cold drawing, and a precise stable treatment post-phosphating to ensure their unparalleled quality. The production techniques divide these wires into two distinct categories: the robust cold-drawing steel wire and the exceptionally durable stress-eliminating steel wire. Moreover, based on the immaculate surface conditions, they are further classified into plain steel wires, intricately designed indentation steel wires, and the elegantly twisted spiral rib steel wires. Cold drawing wire stands out as a cornerstone material, providing unmatched strength and dependability for prestressed concrete applications.
Raw Material Requirements
The cornerstone of producing premium prestressed concrete lies in the meticulous selection of high-caliber carbon steel wire rods, notably SWRH77B or SWRH82B. These materials are evaluated against stringent criteria encompassing dimensions, geometrical precision, weight, and permissible deviations. Additionally, their grade, precise chemical composition, cutting-edge smelting methodologies, and the condition upon delivery are scrutinized. The mechanical prowess, depth of decarbonization layers, intricate micro-structural integrity, flawless surface finish, and any specialized stipulations are carefully analyzed to ensure they align with the highest industry benchmarks.
Cooling is meticulously regulated through advanced Sterem technology, achieving an impressive Sotenization rate surpassing 85%. This innovative cooling approach ensures that the coils produced meet and exceed the demanding production standards required for prestressed concrete steel wire and steel strand. With Sterem technology, reliability and superior performance are guaranteed, even in the most challenging construction scenarios.
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
The application spectrum of prestressed steel wire for concrete is both vast and varied, finding its indispensability in constructing single-story and multi-story residences, robust highway and railway bridges, durable sleepers, utility poles, and high-pressure water pipelines. Additionally, these wires are pivotal in forming storage tanks, water towers, and have expanded their utility in modern marvels such as towering skyscrapers, subterranean buildings, intricate high-rise structures, and critical hydraulic and marine constructions. Their usage extends to airport facilities, encompassing both runways and terminal structures, and the pressure vessels of ***s. These wires cater to a multitude of industries, adeptly supporting projects of mammoth scale, extraordinary span, significant volume, expansive area, and substantial loads. Their adaptability in diverse structural engineering tasks, across various shapes and functions, underscores their unparalleled versatility and strength.
