为了提高钎钢的使用效果,即延长其使用寿命,必须在制造钎杆时选择适当的热处理制度。文中详细介绍和分析了按不同热处理制度生产的钎杆进行工业和实验台试验时所获得的寿命资料,并提出主要结论:感应加热优于其它加热方式;淬火后硬度32～36HRC是最佳的热处理制度;经热处理强化的钎杆平均寿命提高0.5～1.0倍。本文对改进钎杆使用效果具有重要参考价值。
In order to improve the effect of brazing steel, that is to extend its service life, it is necessary to select an appropriate heat treatment system in the manufacture of drill rods. In this paper, the life data of the drill rods produced by different heat treatment systems are introduced and analyzed in detail. The main conclusions are drawn as follows: Induction heating is superior to other heating methods; hardness of 32 ~ 36HRC after quenching is the best Heat treatment system; by heat treatment to enhance the average life expectancy of drill rod 0.5 to 1.0 times. This article has important reference value for improving the effect of drill rod.
