Abstract

The invention discloses a making method of an alloy coat coated prestressed steel wire. The method comprises the following steps: 1, preparing an alloy coat which is powdery; 2, sequentially carrying out pickling treatment phosphatization treatment and surface drying treatment of a prestressed steel wire rod; 3, sending the above obtained treated prestressed steel wire into a drawing machine, drawing to obtain the prestressed steel wire having required specifications and dimensions, and cleaning the prestressed steel wire; 4, sending the prestressed steel wire into a hot spraying device, uniformly spraying the surface of the prestressed steel wire with the prepared alloy powder by a spray gun, allowing the sprayed prestressed steel wire to an intermediate frequency heating furnace, and heating the prestressed steel wire to 550-570DEG C within 5-8s; and 5, allowing the prestressed steel wire to enter a quenching cooling device, cooling through a second cooling operation, air-cooling to room temperature, allowing the prestressed steel wire to a take-up machine, examining, and warehousing to obtain the alloy coat coated prestressed steel wire. The method increases the strength of the prestressed steel wire, further improves the wear resistance and the corrosion resistance of the prestressed steel wire, and prolongs the service life of the prestressed steel wire.

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...
