采煤机截齿盐浴钎焊──热处理一体化工艺研究

Study on the Integration of Salt-Bath Brazing with Heat Treatment of Cutters for Mining Machinery

本文研究了３５ＣｒＭｎｓｉ钢与ＹＧ１１Ｃ硬质合金高频钎焊与盐浴钎焊工艺．根据钎缝剪切强度和３５ＣｒＭｎＳｉ钢性能等方面探讨了盐浴钎焊、热处理一体化工艺代替高频钎焊焊后重新加热热处理工艺的可行性．

n this thesis, high-frequency Btazing (HFB) and salt-bath brazing(SBB)for 35CrMnSiSteel and YG11C ceramic are investigated and the feasibility of substituting the integrated prccers of SBB and beat-treatment for the process of HFB and reheating treatment is also discussed in view of the shearing strength of brazing joint and the tensile properties of 35CrMnSi steel.
