Cov Cim Tseg) 1. Thaum lub cev los tiv thaiv kev laus muaj qhov tshwj xeeb hauv SGCD3 nplooj ntawv thiab coils, cov yam ntxwv los tiv thaiv kev laus muaj kev lav zoo rau rau (6) lub hlis tom qab xa khoom los ntawm cov tsim khoom.
Kev tiv thaiv kev laus yog hais txog tus yam ntxwv tiv thaiv kev ua kom tsis txhob ua mob los ntawm kev tshwm sim thaum tsim khoom.
2. Hauv txoj ntsiab cai, kev ntsuas lub zog tensile tsis ua rau ntawm cov phaj nrog tuab hauv qab 0.25mm
3. SGCC cov khoom lag luam feem ntau muaj cov ntsiab lus ntau dua 205N / mm2 thiab lub zog tensile ntau dua 270N / mm2.
Tshuaj lom neeg cov cuab yeej siv tshuaj thiab lub cev muaj peev xwm
