【 摘 要 】
At the present moment the top priority issues are becoming the aspects of resource and utility saving in the process of manufacturing of gauged bars for upsetting of fastening for motor vehicles while providing its better quality and competitive ability. The dominating factor in this direction is the enhancing of efficiency of the full process chain by means of cost saving for both metal and energy. This paper is presenting the results of research of the method for preparation of 38XA steel that has proved itself good for manufacturing of fastening elements in the car industry. It has been proved that drawing of the rolled stock with optimal drafting ensures absence of ellipticity and scale. The available light oxide coating has been removed by etching during some seconds. The resource saving rolled stock processing method is ecologically friendly, causes formation of highly dispersed equally spaced structure and increases the capacity to metal forming. Thereby this increases the upsetting tools service life. At the same time, the absence of the decarburization layer enables to reduce the number of transitions in the process of upsetting of metal articles.【 预 览 】
