摘　　要：对金属针布生产与使用特点进行分析 ,认为最佳的钢丝球化退火工艺是金属针布尺寸精度、基体组织、最终淬火质量的保证。对于 5 7B针布钢丝 ,采用低于Ac12 0～ 4 0℃的球化退火温度可使球化级数达到 3～ 3.5级 ,硬度达到 170～ 190HV ,满足高速轧制要求。金属针布钢丝球化退火质量的控制与管理 ,对金属针布稳定化生产和产品质量的一致性起重要的作用。To analyze the manufacturing and use features of metal card clothing. It is considered that the best spheroidization annealing technology of steel wire is the assurance of dimension precision, matrix and final quenching quality of metal card clothing. When spheriodization annealing at 20～40 ℃ below Ac 1 ,the spheroidization grade of the 57B metal card clothing is up to 3～3.5,the hardness is 170～190 HV,which can meet the requirements of high speed rolling. The quality control and supervision of metal card clothing steel wire spheroidization annealing have important effect on metal card clothing stabilized manufacturing and its accordance of products quality.
