Amamodeli nezinto zokwakha zenqwaba yeshidi lensimbi ye-lasen

 

Izinhlobo zeizinqwaba zeshidi lensimbi
Ngokuvumelana ne "Inqwaba Yeshidi Lensimbi Egoqiwe Eshisayo” (GB∕T 20933-2014), inqwaba yensimbi egoqwe ngokushisa ihlanganisa izinhlobo ezintathu, izinhlobo ezithile kanye namagama azo ekhodi yilezi ezilandelayo:Inqwaba yeshidi lensimbi yohlobo lwe-U, igama lekhodi: Inqwaba yeshidi lensimbi yohlobo lwe-PUZ, igama lekhodi: Inqwaba yeshidi lensimbi eqondile ye-PZ, igama lekhodi: PI Qaphela: lapho u-P eyinhlamvu yokuqala yenqwaba yeshidi lensimbi ngesiNgisi (iNqwaba), kanye no-U, Z, kanye no-I kumelela ukuma kwenqwaba yeshidi lensimbi.

 

Isibonelo, inqwaba yensimbi yohlobo lwe-U esetshenziswa kakhulu, i-PU-400X170X15.5, ingaqondwa njengobubanzi obungu-400mm, ukuphakama okungu-170mm, ukujiya okungu-15.5mm.

Inqwaba yeshidi lensimbi yohlobo lwe-U

 

Kungani kungelona uhlobo lwe-Z noma uhlobo oluqondile kodwa uhlobo lwe-U oluvame ukusetshenziswa kwezobunjiniyela? Eqinisweni, izici zemishini zohlobo lwe-U nohlobo lwe-Z ziyafana ngokuyisisekelo kolulodwa, kodwa inzuzo yenqwaba yensimbi yohlobo lwe-U ibonakala esenzweni esihlangene sezinqwaba eziningi zensimbi yohlobo lwe-U.

 

Kusukela esithombeni esingenhla, kungabonakala ukuthi ukuqina kokugoba ngemitha ngayinye yomugqa wenqwaba yensimbi yohlobo lwe-U kukhulu kakhulu kunokwenqwaba yensimbi yohlobo lwe-U eyodwa (indawo ye-axis engathathi hlangothi ishintsha kakhulu) ngemva kokuba inqwaba yensimbi yohlobo lwe-U ilunywe ndawonye.
2. Izinto zensimbi ezinqwabelene
Ibanga lensimbi i-Q345 likhanseliwe! Ngokusho kwe-“Low Alloy High Strength Structural Steel” GB/T 1591-2018 ejwayelekile, kusukela mhla lu-1 kuNhlolanja 2019, izinga lensimbi i-Q345 likhanseliwe futhi lashintshwa laba yi-Q355, elihambisana nebanga lensimbi i-S355 ejwayelekile ye-EU. I-Q355 iyinsimbi evamile enamandla aphezulu ene-alloy ephansi enamandla angu-355MPa.
