Description

Technical Field

[0001] The utility model relates to the field of quenching equipment, in particular to a prestressed steel strand quenching equipment. Background Art

[0002] Prestressed steel strand is a twisted steel cable composed of 2, 3, 7 or 19 high-strength steel wires, and has been stress-relieved. It is suitable for prestressed concrete and similar purposes. Prestressed steel strand is mainly used in post-tensioned and pre-tensioned prestressed concrete projects, with the largest amount used in bridge structures. Prestressed steel strand needs to be quenched using quenching equipment during the production process.

[0003] In the existing prestressed steel strand quenching equipment, the prestressed steel strand is generally directly passed through the quenching equipment, and quenched and cooled under the action of the coolant in the quenching equipment. However, the direct crossing requires that the length of the quenching equipment must be long enough to achieve the quenching and cooling effect. The too long quenching equipment is not only costly, but also the prestressed steel strand is only cooled at a single height. For the too long prestressed steel strand, the longer the time, the worse the cooling effect. Moreover, when the prestressed steel strand passes through the quenching equipment, a large amount of coolant is easily taken away from the surface, resulting in a waste of coolant. In addition, a large amount of smoke is generated during quenching and cooling. These smoke are likely to cause air pollution and damage the human respiratory tract. Utility Model Content
