Ucingo lwentsimbi oluxineneyo luyinto eguquguqukayo nebalulekileyo kushishino lokwakha. Lwenziwe ngeentambo zentsimbi ezishushu eziqengqelekayo zentsimbi eshushu eziphathwa ngobushushu kwaye zisebenza kubanda, ezi ntambo zenzelwe ngokukodwa ukuhlangabezana neemfuno ezifunekayo zokuqinisa ikhonkrithi exineneyo. Ucingo lwentsimbi lunomxholo wekhabhoni ophakathi kwe-0.65% ukuya kwi-0.85%, umxholo wesalfure kunye ne-phosphorus ongaphantsi kwe-0.035%, kwaye lunamandla kwaye luhlala ixesha elide.
Ucingo lwentsimbi oluxinzelelweyo luye lwenza inkqubela phambili enkulu ukusukela kwimveliso yalo yemizi-mveliso kunye nokusetyenziswa kwalo ngeminyaka yoo-1920. Namhlanje, kuye kwenziwa iintlobo ngeentlobo zeemveliso ezifanelekileyo kwizicelo ezahlukeneyo kwaye zineempawu ezahlukeneyo. Ezi ziquka ucingo olutsalwa ngokubandayo, ucingo oluthe tye, ucingo oluphumlayo oluphantsi, ucingo olugqunyiweyo kunye nocingo olunemigca. Ezi mveliso, zidityaniswe nemicu yentsimbi exinzelelweyo, ziye zaba zezona ntlobo zentsimbi ezixinzelelweyo ezisetyenziswa kakhulu kwihlabathi liphela.
Ngokuphathelele udidi, ucingo lwePC olune-serrated oluphantsi lukhetho oludumileyo. Amandla alo abalaseleyo okutsalwa alwenza lube lolona lufanelekileyo kwiindlela zokusetyenziswa ezixineneyo kakhulu. Ukongeza, ubukhulu bocingo lwentsimbi yi-2.64 mm, nto leyo eyenza ukuba lufaneleke kwiiprojekthi ezahlukeneyo zokwakha. Ukongeza, olu cingo lwekhonkrithi oluxineneyo luhambelana nemigangatho echazwe kwi-1084 SAEJ403, ukuqinisekisa umgangatho kunye nokuthembeka kwalo.
Enye yezona zinto zibalulekileyo ngocingo lwentsimbi oluxinzelelweyo ngamandla alo angaqhelekanga okuxinzelela. Ngokubanzi, amandla okuxinzelela olu hlobo locingo lwentsimbi angaphezulu kwe-1470MPa, etshintsha kancinci ukuya kwinqanaba eliphambili lamandla eliyi-1670 ~ 1860MPa. Ngaphezu koko, ububanzi bocingo buye batshintsha ngokuhamba kwexesha, ukusuka kwi-3 ukuya kwi-5 mm ukuya kuluhlu lwangoku lwe-5 ukuya kwi-7 mm. La mandla akhulayo kunye nobubanzi obukhulu kwenza ucingo oluxinzelelweyo lube lula kakhulu kwaye lukwazi ukumelana nemithwalo emikhulu.
Ngenxa yeempawu zayo ezintle, ucingo lwentsimbi oluxinzelelweyo lusetyenziswa kakhulu kwiindawo ezahlukeneyo zokwakha. Lusetyenziswa kakhulu ukuqinisa izakhiwo ezifana neebhulorho, izakhiwo kunye neendlela zikaloliwe ukuphucula amandla azo okuthwala umthwalo kunye nokuqina kwesakhiwo ngokubanzi. Amacandelo emizi-mveliso kunye neziseko zophuhliso axhomekeke kakhulu kwiintambo zentsimbi ezixinzelelweyo ukuqinisekisa ukuba iiprojekthi zawo zihlala ixesha elide kwaye zikhuselekile.
Ngamafutshane, uphuhliso lwengcingo yentsimbi exineneyo lutshintshe kakhulu ishishini lokwakha. Ukudibanisa intsimbi esemgangathweni ophezulu enekhabhoni ephezulu kunye neendlela eziphambili zoomatshini kuphumela kuluhlu lweemveliso ezifanelekileyo kwiintlobo ngeentlobo zezicelo. Ngoluhlu olubanzi lohlu kunye nobungakanani, kunye namandla okutsalwa agqwesileyo kunye nokusetyenziswa okuninzi, ingcingo yentsimbi exineneyo isalokhu iyinxalenye ebalulekileyo kulwakhiwo lwanamhlanje.
Isicelo
Njengoko ishishini lezinto zesinyithi laseTshayina likhokela amashishini, urhwebo lwesizwe lwentsimbi kunye ne-logistics "Ikhulu leenkampani ezilungileyo", amashishini orhwebo lwentsimbi laseTshayina, "Amashishini abucala ali-100 aphezulu eShanghai". I-Shanghai Zhanzhi industry Group Co., Ltd., (efinyezwe kwi-Zhanzhi Group) ithatha "Ingqibelelo, ukuSebenza, ukuVula, ukuPhumelela" njengomgaqo wayo wokusebenza, ihlala iqhubeka nokubeka iimfuno zabathengi kwindawo yokuqala.
