Problems solved by technology

The key factor that restricts the performance index of the fan spindle is how to improve the toughness of the spindle product. According to professional analysis, poor quenching is the key factor that leads to the inability to improve the toughness. Complete quenching and product cracking form a contradiction, which cannot be pursued in a single way. The quenching effect must be considered comprehensively to achieve a suitable node

Description

technical field [0001] The invention relates to a quenching device for the main shaft of a blower fan for large forgings. Background technique [0002] At present, almost all fan shafts are large-scale forgings. The heat treatment process of fan shafts is quenching and tempering (quenching + high temperature tempering). Fans have been in harsh environments for a long time. As an important component, the performance indicators of the shaft are very strict. The key factor that restricts the performance index of the fan spindle is how to improve the toughness of the spindle product. According to professional analysis, poor quenching is the key factor that leads to the inability to improve the toughness. Complete quenching and product cracking form a contradiction, which cannot be pursued in a single way. The quenching effect must be considered comprehensively to achieve a suitable node. Contents of the invention [0003] The purpose of the present invention is to provide a l...
