Abstract

The invention discloses a method for manufacturing prestressed steel wire coated with alloy coating. The method is carried out in the following steps: (1) Alloy coating is arranged, and the alloy coating is in powder form; (2) Prestressed steel wire is pickled sequentially with wire rod treatment, phosphating treatment and surface drying treatment; (3) send the treated prestressed steel wire into the wire drawing machine and draw it into the required specification and size, and then clean the prestressed steel wire; (4) send the prestressed steel wire into the thermal spraying equipment, and configure The good alloy powder is evenly sprayed on the surface of the prestressed steel wire with a spray gun, enters the intermediate frequency heating furnace, and heats the prestressed steel wire to 550-570°C within 5-8 seconds; (5) the prestressed steel wire enters the quenching cooling device, passes The second cooling process is cooled, and finally air-cooled to room temperature, then enters the wire take-up machine, inspects and puts into storage; thereby obtains the prestressed steel wire coated with alloy coating; the present invention increases the strength of the prestressed steel wire, and the wear resistance and resistance The corrosion resistance is further improved and the service life is increased.

Description

technical field [0001] The invention relates to a processing method of steel wire, in particular to a manufacturing method of alloy-coated prestressed steel wire. Background technique [0002] At present, in the existing technical conditions, when using prestressed steel wire, the environment used is extremely harsh, and there are corrosive gases or liquids in many cases, which can easily lead to corrosion and rust of the prestressed steel wire, which greatly reduces the prestressed steel wire. The service life of steel wire, and caused certain potential safety hazard, increased production cost, wasted a large amount of manpower and material resources for maintenance, wasted a large amount of resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a method for manufacturing prestressed steel wire coated with alloy coating in view of the above shortcomings of the prior art, which realizes the coating of a layer...
