摘　　要：首先根据砂锯切割机理,分析切割过程中对锯条的性能要求,并指出锯条的制造工艺流程中应重点控制好熔炼、加热、轧制、冷却等环节,最终获得锯硬度最佳值为HRC28-37,抗拉强度为σb≥950MPa,金相组织为细匀索氐体的最好综合性能.然后根据锯条使用特点,提炼了掌握锯条的紧固、变形量控制及锯条连杆的偏移量控制等关键技术,并对锯切过程锯条几何中心与石材中心偏移问题,提出解决办法.On the base to the gang saw cutting mechanism, the performance requirements of saw blade during the cutting process and the key manufaeturing technology was analysed, the result showed the best comprehensive mechanical properties of saw blade is that the mierostrueture is homogeneous sorbite, the hardness obtained optimum value is 28 to 37 HRC, the tensile strength is over 950 MPa. Then according to the characteristics of saw blade, the key technology how to master saw blade fastening, control the connecting rod deformation and the offset were pointed out.
