Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing, in particular to a steel bar heating and quenching water recycling device. Background Art

[0002] Steel rods have been widely used in prestressed components such as high-strength prestressed concrete centrifugal pipe piles, electric poles, viaduct piers, railway sleepers, etc. abroad due to their high strength and toughness, low relaxation, strong bond with concrete, good weldability, upset forging properties, and material saving (such as φ11mm PC steel rods can replace φ20mm hot-rolled steel bars). They have a very broad market internationally, especially in Asia.

[0003] At present, during the processing of steel bars, it is necessary to first cut the steel bars into steel bars of uniform length, and then perform quenching and tempering treatment. After the steel bars are cut, they need to be heated to several hundred degrees, and then quenched under water cooling conditions. After the steel bars are cut, there will be some metal chip powder on the surface. At this time, when water-cooled quenching is performed, the metal chip powder on the surface of the steel bars will be washed into the water. If the quenching is carried out for a long time, the metal chip powder will be accumulated, and the high-temperature water after quenching cannot be recycled. This is the shortcoming of the existing technology. Utility Model Content
