A groove-type cable bridge and an anticorrosion process thereof

Abstract

The invention discloses a groove-type cable bridge, comprising a groove frame and a shield arranged on the groove frame, wherein the groove frame comprises the following components in percentage by mass: C: 0.15-0.19%, Cr:1.0-3.0%, Si:2-4%, Al:0.5-0.9%, Ti:0.2-0.5%, Cu:0.05-0.08%, B:0.05-0.08%, Sb:0.1-0.3%, Mo:0.2-0.35%, Zr:0.03-0.05%, Zn:0.5-0.8%, Nb:0.05-0.07%, Mn:0.45-0.48%, S:0.003-0.005%, P:0.005-0.007%, V: 0.01-0.03%, rare element: 0.15-0.18%, the rest is Fe and inevitable impurities; the invention also designs an anticorrosion process of the groove cable bridge, which has good anticorrosion performance and long service life.

Description

technical field [0001] The invention relates to a bridge frame, in particular to a grooved cable bridge frame and its anti-corrosion process. Background technique [0002] The cable tray is a rigid structural system with closely connected supporting cables composed of straight sections, bends, components, brackets, hangers, etc. of trays or ladders.

Problems solved by technology

[0002] The cable tray is a rigid structural system with closely connected supporting cables composed of straight sections, bends, components, brackets, hangers, etc. of trays or ladders. It is mainly used for comprehensive wiring such as power supply supporting power transmission and wired telecommunication transmission, laying cables This kind of supporting member is most widely used in the supply department of the store, the power transmission system of centralized power supply and distribution of industrial and mining enterprises, hotels, and comprehensive office facilities, and wired telecommunications; the existing cable bridges are mostly linear, and the shape Relatively single, when the cable needs to change direction, only two straight cables can be connected vertically, the transition is not smooth, and the cable is bent too seriously, often resulting in damage to the bend, affecting normal use, and reducing the service life of the cable. In order to overcome the above defects, those skilled in the art have developed a trough cable tray, which is a fully enclosed cable tray, which is most suitable for laying computer cables, communication cables, thermocouple cables and other highly sensitive cables. The control cable of the system, etc., it has a good effect on the shielding interference of the control cable and the protection of the cable in the heavy corrosion environment, so the scope of application is getting wider and wider;

[0003] At present, the design of the cable bridge is unreasonable, the service life is short, the corrosion resistance is low, the strength is low, the wear resistance is poor, the use cost is high, and the construction efficiency is relatively low
