淬火工艺是保证钢丝圈开口拉伸变形率的关键

Quenching Process is the Key to Guarantee the Rate of the Open Elasticity of Wire Rolls

针对钢丝圈热处理后存在的“软硬混杂”现象 ,对有关工序进行多次反复试验 ,并采用钢丝圈开口拉伸测量仪精确测量其开口距离 ,重点在淬火工序采取了诸项改进措施 ,使钢丝圈的淬火质量有了较大幅度的提高 ,“软硬混杂”现象基本得以控制 ,开口拉伸变形率合格率达 80

Through repeated test on related process on the travellers which are hest treated.Something is done to much improve the quality of the travellers in which there 'soft plus hard'mixture.The quality of the rate of open elasticity reach to 80% above the grade in regarding the open deformation.
