Specifications Introduction
Prestressed steel wire signifies an exceptional category of steel wire crafted from superior high-carbon steel plates. These plates undergo meticulous processes such as acid washing, cold drawing, or consistent treatment post-phosphating. Depending on the manufacturing technology, they are categorized into cold-drawing steel wire and stress-eliminating steel wire. Furthermore, based on surface conditions, the steel wire is classified into plain steel wire, indentation steel wire, and spiral rib steel wire. Cold drawing wire is predominantly used in prestressed concrete applications following the cold drawing process.
Raw Material Requirements
The quintessential raw materials for crafting prestressed concrete include high-quality carbon steel wire rods, specifically SWRH77B or SWRH82B. These wire rods must adhere to stringent standards concerning size, shape, weight, and permissible deviations. Other critical parameters include grade and chemical composition, smelting techniques, delivery conditions, mechanical properties, decarbonization layer, micro-structure, surface quality, in addition to any bespoke requirements.
Cooling is meticulously regulated by Sterem technology, ensuring an impressive over 85% Sotenization rate. Generally, coils crafted through standard processes meet all necessary production criteria for prestressed concrete steel wire and steel strand.
Standards of Steel Wire for Prestressed Concrete
The prevailing standards are set forth as 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 for steel wire designated for prestressed concrete is extensive, encompassing single-story and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its utility extends to contemporary high-rise buildings, subterranean structures, towering edifices, hydraulic structures, marine installations, airport infrastructures (including runways and terminal buildings), and pressure vessels within nuclear power facilities. The steel wire is essential across diverse sectors, particularly in super-tall, super-span, super-volume, and super-large area projects, as well as constructions bearing overweight loads. It supports various structural engineering projects, distinguished by their unique shapes and multifaceted functions.
