Ucingo lwensimbi olucindezelwe lunomlando omude, futhi ukukhiqizwa kwalo kwezimboni kanye nokusetshenziswa kwalo kungalandelelwa emuva ngawo-1920. Luye lwathuthuka kakhulu eminyakeni edlule, okwaholela emikhiqizweni eyahlukahlukene enezakhiwo ezahlukene ezifanele ukusetshenziswa okuhlukahlukene. Lokhu kufaka phakathi ucingo oludonswayo olubandayo, ucingo oluqondile noluthambile, ucingo oluphansi lokuphumula, ucingo oluhlanganisiwe kanye nocingo olunezinti. Le mikhiqizo kanye nemicu yensimbi ecindezelwe eyenziwe ngayo iye yaba izinhlobo zensimbi ezicindezelwe ezisetshenziswa kakhulu emhlabeni jikelele.
1) Okujwayelekile: ASTM A-421
2) Usayizi: 3mm-12mm
3) Amandla okuqina: ≥1700Mpa
4) Isisindo sekhoyili: 800-1500kg
5) Ukupakisha: Iphakheji Efanelekela Ulwandle
Ucingo lwensimbi olucindezelwe oluyi-12.7mm luwucingo lwensimbi olunekhabhoni ephezulu oluklanyelwe ngokukhethekile ukuhlangabezana nezidingo zokuqinisa zekhonkrithi ecindezelwe. Lwenziwe ngenduku yocingo olugoqiwe olushisayo oluyinsimbi enekhabhoni ephezulu oluphathwa ngokushisa futhi olusebenza ngokubanda ukuze kutholakale izakhiwo ezidingekayo. Okuqukethwe kwekhabhoni kwalolu hlobo lwentambo yensimbi kungu-0.65% kuya ku-0.85%, kanti okuqukethwe kwesulfure ne-phosphorus kuphansi, kungaphansi kuka-0.035%.
Amandla okuthamba kwentambo yensimbi ngokuvamile angaphezu kuka-1470MPa, futhi izinga lamandla liye lashintsha kancane kancane lisuka ku-1470MPa kanye no-1570MPa laya ku-1670~1860MPa. Ngokuphathelene nobubanzi, intambo yensimbi ikhule isuka ku-3mm yaya ku-5 kuya ku-7mm yamanje.
Ngokombono wokuhlukanisa, ucingo lwensimbi olucindezelwe oluyi-12.7mm lungolwensimbi yensimbi ecindezelwe esezingeni eliphezulu. Luklanyelwe ngqo ukuhlangabezana nezidingo zokuqinisa ukhonkolo olucindezelwe, olunikeza amandla esakhiwo kanye nokuqina kumaphrojekthi okwakha asetshenziswa yilo.
Uma sibheka imininingwane, ucingo lwensimbi olucindezelwe oluyi-12.7mm lunokuqukethwe kwekhabhoni okungu-0.65% kuya ku-0.85%, okuqinisekisa ukusebenza okudingekayo ukuze kube nempahla eqinile nehlala isikhathi eside. Lunokuqukethwe okuphansi kwesibabule ne-phosphorus, okuthuthukisa ukusebenza kwalo. Amandla okubamba ucingo makhulu kune-1470MPa, kanti ububanzi buphakathi kuka-5 kuya ku-7mm.
Ucingo lwensimbi olucindezelwe oluyi-12.7mm lusetshenziswa kabanzi kumaphrojekthi ahlukahlukene okwakha ngenxa yamandla alo aphezulu okubamba kanye nokusebenza kahle kakhulu. Lusetshenziswa kakhulu ezakhiweni zekhonkrithi ezicindezelwe ukuze kuqinisekiswe futhi kuqiniswe. Kungakhathaliseki ukuthi lusetshenziswa emabhulohweni, ezakhiweni noma kwamanye amaphrojekthi engqalasizinda, lolu cingo lwensimbi luqinisekisa ukuqina nokusebenza okuhlala isikhathi eside kwezakhiwo oluzisekelayo. Ukuguquguquka kwalo kanye nokuthembeka kwalo kuyenza ibe yingxenye ebalulekile yezakhiwo zanamuhla.
Ngamafuphi, ucingo lwensimbi olucindezelwe oluyi-12.7mm luwumkhiqizo osezingeni eliphezulu ohlangabezana nezidingo zokuqinisa zekhonkrithi ecindezelwe. Amandla ayo aphezulu, okuqukethwe kwayo okuphansi kwe-sulfur ne-phosphorus, kanye nemininingwane ehlukahlukene kwenza kube kuhle kakhulu ezinhlotsheni ezahlukene zezicelo zokwakha. Ngomlando wayo omude nokuqashelwa emhlabeni jikelele, lolu cingo lwensimbi selube yingxenye ebalulekile embonini yokwakha, okuqinisekisa ukuqina nokuqina kwezakhiwo emhlabeni jikelele.
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.
