摘要
挖泥船的铰刀齿采用30Cr2MoNiMnSi铸钢制作,工况恶劣,必须进行热处理强化。该绞刀齿铸件经1080℃油淬、500℃回火,然后890℃油淬、320℃回火后,力学性能达到了要求。
A type of reamer tooth, made of 30Cr2MoNiMnSi cast steel, must be strengthened by heat treating owing to its severe operating condition. The reamer tooth was quenched from 1080 ℃ in oil and tempered at 500 ℃, subsequently quenched from 890 ℃ in oil and tempered at 320 ℃ , as a result, its mechanical properties have conformed with the requirements.
