Magnesium pack steel wire main cable steel tendon and manufacturing method thereof

Abstract

The invention discloses a magnesium pack steel wire main cable steel tendon and a manufacturing method thereof, and relates to the technical field of steel wire main cable steel tendon manufacturing methods. The magnesium pack steel wire main cable steel tendon aims to solve the problems that the manufacture of common anchorage devices are generally only subjected to flaw detection by using ultrasonic waves, the detection is insufficient, and the potential safety hazard is easily caused due to the fact that the residual anchorage devices are used. The method comprises the following steps that1, the detection, acid pickling and high-pressure washing are carried out on high-carbon steel wire rods; 2, phosphorization, washing and drying are carried out; 3, stretching is carried out; 4, electrolytic degreasing, acid pickling and electrolytic magnesium plating are carried out; 5, polishing is carried out, and marking wires are manufactured; 6, wires releasing, wires coiling, dragging, packwinding and shaping are carried out, and marking wires are cut off; 7, the anchorage device is subjected to making and detecting; 8, the quality detection is carried out on the whole main steel wiremain cable steel tendon; and 9, the steel wire main cable steel tendon is subjected to stacking and packing.

Description

technical field [0001] The invention relates to a magnesium-clad steel wire main cable strand and a manufacturing method thereof, and relates to the technical field of a steel wire main cable strand manufacturing method. Background technique [0002] The steel wire main cable is one of the most important load-bearing components of the suspension bridge and the lifeline of the suspension bridge. The current mainstream form of the main cable of the suspension bridge is the parallel steel main cable, which is made of multiple high-strength steel wires in the factory and assembled into the main cable at the construction site. At present, the main cable of domestic suspension bridges mainly chooses PWS prefabricated parallel steel wire bundles (cable strands). Generally, the main cable of suspension bridges is composed of several strands, and the strands are assembled by a number of high-strength galvanized steel wires. The ends of the strands are equipped with anchors. [0003]...
