Problems solved by technology
[0003] In order to improve the structural strength of the steel strand, it is necessary to heat-treat the surface of the steel strand; the current steel strand mainly has the following problems in the process of heat treatment: there is a certain bending on the surface of the steel strand, which affects the steel strand during heat treatment. The treatment effect; and the bending of the outer wall of the steel strand will affect the movement effect of the steel strand in the process of winding and trimming; it is difficult to ensure that the outer wall of the steel strand is heated evenly in the process of heat treatment on the surface of the steel strand, and the steel strand In the process of water quenching and cooling, the outer wall of the steel strand cannot be completely cooled by one-time immersion water cooling

Embodiment Construction
[0034] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific drawings. It should be noted that, in the case of no conflict, the embodiments and Features in the embodiments can be combined with each other.
[0035] Such as Figure 1 to Figure 9 Shown, a kind of prestressed steel strand manufacturing heat treatment method, the manufacturing heat treatment steps of concrete prestressed steel strand are as follows:
[0036] S1. Steel strand fixing: Manually place the coiled steel strand on the unwinding device, and pull out one end of the coiled steel strand to pass through the outer limit unit 1, straightening unit 2, heating unit 3 and cooling in sequence The unit 4 is also fixed on the winding device; respectively operate the No. 1 adjusting lever 22 and the No. 2 adjusting lever 26 to control the relative height between...

The invention provides a prestressed steel strand manufacturing heat treatment method. Manufacturing heat treatment of a prestressed steel strand is completed through cooperation of an outer limiting unit, a straightening unit, a heating unit and a cooling unit. The prestressed steel strand manufacturing heat treatment method provided by the invention can solve the problems that certain bending exists on the surface of a steel strand in the heat treatment process of the current steel strand, and the treatment effect of the steel strand is influenced during heat treatment; the bending of the outer wall of the steel strand can influence the moving effect of the steel strand in the rolling and trimming process; and the uniform heating of the outer wall of the steel strand is difficult to ensure in the heat treatment process of the surface of the steel strand, and the complete cooling of the outer wall of the steel strand cannot be ensured through one-time soaking type water cooling in the water quenching cooling process of the steel strand.
Description
technical field [0001] The invention relates to the technical field of steel material processing, in particular to a heat treatment method for manufacturing prestressed steel strands. Background technique [0002] The stranded wire is a steel product composed of multiple steel wires, which can be divided into prestressed steel strands, unbonded steel strands, galvanized steel strands, etc. Its carbon steel surface can be added with galvanized layer, zinc-aluminum alloy layer, aluminum-clad layer, copper-plated layer and epoxy resin coating as required. [0003] In order to improve the structural strength of the steel strand, it is necessary to heat-treat the surface of the steel strand; the current steel strand mainly has the following problems in the process of heat treatment: there is a certain bending on the surface of the steel strand, which affects the steel strand during heat treatment. The treatment effect; and the bending of the outer wall of the steel strand will a...
