Abstract

The invention relates to the technical field of steel bar processing and production technology and relates to a spray quenching device and a steel bar production line. The spray quenching device comprises a box, a 360-degree quenching cooling sprinkler, a semicircular quenching cooling sprinkler and a 180-degree quenching cooling sprinkler. The bar body is firstly transmitted to the 360-degree quenching cooling sprinkler for quenching cooling; then, the bar body is transmitted to the semicircular quenching cooling sprinkler for accelerated cooling; then, the bar body enters the 180-degree quenching cooling sprinkler for accelerated cooling; and finally, quenching cooling ends. Through operation of a first nozzle, 360-degree all-dimensional quenching cooling is realized such that the heated steel bar body can be quenched and cooled 360 degrees to achieve no-blind zone quenching, no soft spots, no soft belt, micro-deformation and achieve bending effect with no deformation after quenching. The steel bar production line comprises a quality control machine and the spray quenching device. In comparison with the prior art, the steel bar production line has above advantages.

Description

technical field [0001] The invention relates to the technical field of steel bar processing and production, in particular to a spray quenching device and a steel bar production line. Background technique [0002] In the current steel bar induction quenching and tempering production line, although some manufacturers have adopted the overall liquid quenching of the steel bar and 180° water spray quenching, which cannot solve the bending deformation of the steel bar during the quenching process, but the quality hidden dangers will occur in the later processing, which will affect the final product quality. steel rod quality. The existing steel bar is quenched by liquid quenching and 180° water spray quenching. During the production operation, after the austenite of the whole steel bar is heated and kept warm, the heated parts enter the quenching cold zone as a whole and spray, resulting in large bending of the steel bar. It is necessary to increase the straightening process to ...
