Ucingo lwensimbi oluqinile, olwaziwa nangokuthi ucingo lwensimbi olunekhabhoni ephezulu, luyizinto zokwakha ezisetshenziswa kabanzi futhi ezinokwethenjelwa ezihlangabezana nezidingo zokuqinisa izakhiwo zekhonkrithi eziqinile. Ucingo lwenziwe ngenduku yensimbi eshisayo egoqwe ngensimbi eshisayo esezingeni eliphezulu, elashwe ngokushisa futhi yasebenza emakhazeni ukuqinisekisa ikhwalithi nokusebenza kwayo okuphezulu. Ucingo lunokuqukethwe kwekhabhoni okungu-0.65% kuya ku-0.85%, okuqukethwe kwesulfure ne-phosphorus okungaphansi kuka-0.035%, futhi lwenziwa ngezindinganiso eziphakeme kakhulu zemboni.
Ucingo lwensimbi olucindezelwe ngaphambili luye lwathuthukiswa amashumi eminyaka kusukela ekukhiqizweni nasekusetshenzisweni kwalo kwezimboni ngawo-1920. Namuhla, uchungechunge lwemikhiqizo ehlukile luye lwakhiwa ukuze kuhlangatshezwane nezidingo zokwakha ezahlukahlukene. Lokhu kufaka phakathi ucingo oludonswayo olubandayo, ucingo oluqondile, ucingo olukhululekile oluphansi, ucingo oluhlanganisiwe kanye nocingo olunezinti. Le mikhiqizo ehlukene, uma isetshenziswa ekwenziweni kwezintambo zensimbi ezicindezelwe ngaphambili, iye yaba izinhlobo zensimbi ezicindezelwe ngaphambili ezisetshenziswa kakhulu emhlabeni.
Amandla okuxhunywa kwezintambo zensimbi zekhonkrithi ezicindezelwe ngokuvamile angaphezu kuka-1470MPa, futhi izinga lamandla alo lishintshe kusuka ku-1470MPa kanye no-1570MPa kuya ku-1670~1860MPa ikakhulukazi. Ububanzi bentambo nabo bushintshile, kusuka ku-3-5 mm kuya ku-5-7 mm. Ukwanda kwamandla nobubanzi kuqinisekisa ukuzinza nokuthembeka kwezakhiwo zekhonkrithi eziqinisiwe.
Izintambo zekhonkrithi ezicindezelwe zisetshenziswa kabanzi embonini yokwakha. Amandla ayo okuqina nokuqina kwayo kwenza ibe yindawo ekahle yokuqinisa izakhiwo zekhonkrithi ezahlukahlukene njengamabhuloho, izakhiwo kanye nemigwaqo emikhulu. Iqeda ngempumelelo ukucindezeleka kokuqina kwekhonkrithi, inciphise imifantu futhi ithuthukise amandla okuthwala umthwalo. Ngaphezu kwalokho, ukuguquguquka kwayo kwenza kube lula ukuyihlela ukuze ihlangabezane nezidingo ezithile zokwakha.
Ngamafuphi, ucingo lwekhonkrithi olucindezelwe luyizinto zokwakha ezisezingeni eliphezulu ezinganikeza ukuqina okuhle kakhulu kwezakhiwo zekhonkrithi ezicindezelwe. Uhla lwemikhiqizo kanye nezici zalo ziqinisekisa ukuthi zonke izidingo zokwakha ziyahlangatshezwa. Ngenxa yamandla alo aphezulu, ukuqina kanye nokuguquguquka, selube yisinqumo esithandwayo embonini yokwakha yomhlaba wonke. Kungakhathaliseki ukuthi lusetshenziswa emabhulohweni, ezakhiweni noma emigwaqweni emikhulu, ucingo lwekhonkrithi olucindezelwe luqinisekisa ukuqina kwesakhiwo kanye nokuphila isikhathi eside.
Isicelo
Njengoba imboni yezinto zensimbi yaseShayina ihamba phambili embonini, ukuhweba ngensimbi kanye ne-logistics kuzwelonke "ibhizinisi elikhulu elinokwethembeka okuhle", amabhizinisi okuhweba ngensimbi yaseShayina, "amabhizinisi azimele ayi-100 aphezulu eShanghai". I-Shanghai Zhanzhi industry Group Co., Ltd., (efinyeziwe ku-Zhanzhi Group) ithatha "Ubuqotho, Ukusebenza, Ukusungula Izinto Ezintsha, Ukunqoba" njengomgomo wayo wokusebenza kuphela, ihlala iqhubeka nokubeka isidingo samakhasimende endaweni yokuqala.
