Specifications Introduction
Prestressed steel wire emerges as an engineering marvel, meticulously fashioned from superior high-carbon steel plates. This intricate creation involves precision processes such as acid washing, cold drawing, and stable treatment following phosphating. Depending on the manufacturing techniques, it divides into two categories: cold-drawing steel wire and stress-relieved steel wire. According to surface textures, it branches into plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawn variant is directly employed for prestressed concrete post its cold drawing.
Raw Material Requirements
The quintessential raw materials for prestressed concrete comprise premium carbon steel wire rods, primarily SWRH77B or SWRH82B. These wire rods must adhere to stringent standards including dimension, shape, weight, and allowable deviations, grade and chemical composition, smelting method, delivery condition, mechanical properties, decarburization layer, microstructure, surface quality, and any specific requirements.
Cooling is executed with utmost precision using the advanced Sterem technology, achieving a remarkable Sotenization rate that surpasses 85%. Typically, coils manufactured through these standard processes meet and exceed the demanding production requirements for prestressed concrete steel wire and steel strand.
Standards of Steel Wire for Prestressed Concrete
The prevailing standards are GB/T5223-2014Prestressed concretesteel wire, in accordance withASTM 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,among others.
Applications for the Reinforcement of Concrete Constructions
Steel wire designed for prestressed concrete shines in reinforcing single-story and multi-story residential buildings, highway and railway bridges, sleepers, electrical poles, pressure water conduits, storage tanks, and water towers. Its utility extends to cutting-edge high-rise buildings, subterranean structures, lofty constructions, hydraulic establishments, marine structures, airport facilities including runways and terminals, and pressure vessels within nuclear power installations. It plays a pivotal role across industries, supporting super-tall, super-span, super-volume, super-large area, and overweight load designs, catering to diverse shape and engineering functions.
