Abstract

The invention discloses cooling equipment for a large bar material, which is used for cooling a bar material (11) after rolling. The cooling equipment is equipped with a short passing water cooler; the bar material (11) penetrates through the short passing water cooler; a water spraying box (2) is arranged on the short passing water cooler at the entering end part of the bar material (11); an annular nozzle (3) is arranged on the spraying box (2). Through adopting the technical scheme, the fast cooling capacity is improved, sufficient cooling is achieved, stability and uniformity of cooling are achieved, and the manufacture requirement of passing water cooling manufacture technology for rolling the large bar material (Phi 60-Phi 150 mm) is satisfied; the products can be manufactured are various and have a wide specification range; the position change is convenient and fast; the bar material product subjected to passing water cooling has increased performance with obvious economical benefits; the cooling equipment is safe and reliable in use, saves energy, protects the environment and is easy for popularization.

Description

technical field [0001] The invention belongs to the technical field of production equipment in the metallurgical industry, and in particular relates to a large-scale bar cooling treatment equipment. Background technique [0002] In the production and processing of bearing steel, controlled cooling is mainly to control the level of reticulated carbides. In the production process, during the cooling process after hot rolling, excessive network carbides (secondary carbides), that is, network carbides, are precipitated along the austenite grain boundaries. The higher the final rolling temperature and the slower the subsequent cooling rate, the more serious the carbide precipitation. [0003] In the prior art, the cooling method of the large bar after rolling cannot guarantee its cooling effect. In terms of water-piercing cooling technology, what the industry can do at present is wire rods, and the research and development of effective water-piercing cooling equipment for large...
