矿用牙轮钻头大跑道材料表面处理分析

Analysis on Materials and Its Heat Treatment of the Roller Raceway in Mi ning Tri-cone Bit

摘要:

分析比较了国内外矿用牙轮钻头所采用材料、热处理工艺的特点 ,欲提高牙轮钻头的寿命 ,除了从材料和热处理工艺方面入手外 ,还需考虑加工、装配等方面因素的影响。

Abstract:

The characteristics of materials and their heat treatments, which are applied to domestic and abroad mining tri cone bit, were carefully checked and compared. It follows from the analyses that the factors of machining and assembling bit should be taken into consideration besides the factors of improving quality of material and its heat treatment, in order to prolong the life of domestic tri cone bit.
