Specifications Introduction
Prestressed steel wire represents a pinnacle in steel technology, crafted meticulously from high-quality high-carbon steel plates. Undergo processes like acid washing, cold drawing, and stable treatment post-phosphating. Distinguished by production technology, it divides into two categories: cold-drawing steel wire and stress-eliminating steel wire. Surface conditions further diversify it into plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire serves as a cornerstone in prestressed concrete, ensuring superior performance.
Raw Material Requirements
The backbone of prestressed concrete lies in high-quality carbon steel wire rods of SWRH77B or SWRH82B. The wire rods must adhere to stringent standards regarding size, shape, weight, and permissible deviation. Essential attributes include grade, chemical composition, smelting method, delivery state, mechanical properties, decarbonization layer, micro-structure, surface quality, and any special requirements. Each element ensures the integrity and performance of the final product.
Cooling is expertly managed through advanced Sterem technology, attaining an impressive over 85% Sotenization rate. This precision ensures that the coils produced are impeccably tailored to meet the rigorous demands of prestressed concrete steel wire and steel strand production, aligning with industry standards.
Standards of Steel Wire for Prestressed Concrete
The prevailing 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
Steel wire for prestressed concrete extends its utility across a wide array of structures: from single-story and multi-story residences to the robustness of highway and railway bridges. It supports infrastructure like sleepers, electric poles, and pressure water pipes, while also fortifying storage tanks and water towers. Its adaptability shines in modern high-rise buildings and underground constructions, reaching into high-rise structures, hydraulic edifices, marine structures, airport buildings (including runways and terminals), and nuclear power plant pressure vessels. It is indispensable in diverse fields, accommodating super-tall, super-span, super-volume, super-large area, and overweight load projects, manifesting in various structural engineering forms and functions.
