Ucingo lwentsimbi oluxineneyo lunembali ende, kwaye imveliso yalo yemizi-mveliso kunye nokusetyenziswa kwalo kunokulandelwa emva kwiminyaka yoo-1920. Luye lwaphuhliswa kakhulu kule minyaka idlulileyo, nto leyo ebangele ukuba kubekho uluhlu lweemveliso ezineempawu ezahlukeneyo ezifanelekileyo kwiintlobo ngeentlobo zezicelo. Ezi ziquka ucingo olutsalwa ngokubandayo, ucingo oluthe tye noluthambileyo, ucingo oluphumlayo oluphantsi, ucingo olugqunyiweyo kunye nocingo olunezikhonkwane. Ezi mveliso kunye nemicu yentsimbi exineneyo eyenziwe ngazo ziye zaba zezona ntlobo zentsimbi ezixineneyo ezisetyenziswa kakhulu kwihlabathi liphela.
1) Umgangatho: ASTM A-421
2) Ubungakanani: 3mm-12mm
3) Amandla okuxinana: ≥1700Mpa
4) Ubunzima bekhoyili: 800-1500kg
5) Ukupakisha: Iphakheji efanelekileyo yolwandle
Ucingo lwentsimbi oluxineneyo oluyi-12.7mm lucingo lwentsimbi olunekhabhoni ephezulu olulungiselelwe ngokukodwa ukuhlangabezana neemfuno zokuqinisa zekhonkrithi exineneyo. Lwenziwe ngentonga yocingo oluxineneyo olushushu oluxutywe nekhabhoni ephezulu olunyangwa ngobushushu kwaye lusebenza kubanda ukuze kufunyanwe iimpawu ezifunekayo. Umxholo wekhabhoni wolu hlobo lwentsimbi yentsimbi yi-0.65% ukuya kwi-0.85%, kwaye umxholo wesalfure kunye ne-phosphorus uphantsi, ungaphantsi kwe-0.035%.
Amandla okutsalwa kwentambo yentsimbi ngokubanzi angaphezulu kwe-1470MPa, kwaye umgangatho wamandla uye watshintsha kancinci kancinci ukusuka kwi-1470MPa kunye ne-1570MPa ukuya kwi-1670~1860MPa ikakhulu. Ngokuphathelele ububanzi, intambo yentsimbi iphuhlile ukusuka kwi-3mm ukuya kuluhlu lwangoku lwe-5 ukuya kwi-7mm.
Ngokwembono yokwahlulahlula, ucingo lwentsimbi oluxineneyo oluyi-12.7mm lulolwentsimbi yentsimbi yekhonkrithi exineneyo ekumgangatho ophezulu. Lwenzelwe ngokukodwa ukuhlangabezana neemfuno zokuqinisa ikhonkrithi exineneyo, nto leyo enika amandla olwakhiwo kunye nozinzo kwiiprojekthi zokwakha ezisebenzisa yona.
Xa sijonga iinkcukacha, ucingo lwentsimbi oluxineneyo oluyi-12.7mm lunomxholo wekhabhoni ophakathi kwe-0.65% ukuya kwi-0.85%, nto leyo eqinisekisa ukusebenza okufunekayo kwisixhobo esomeleleyo nesihlala ixesha elide. Lukwanomxholo ophantsi wesalfure kunye ne-phosphorus, nto leyo ephucula ukusebenza kwalo. Amandla okuxinana kocingo makhulu kune-1470MPa, kwaye ububanzi buphakathi kwe-5 ukuya kwi-7mm.
Ucingo lwentsimbi oluxinzelelweyo oluyi-12.7mm lusetyenziswa kakhulu kwiiprojekthi ezahlukeneyo zokwakha ngenxa yokuba lunamandla aphezulu okutsala kunye nokusebenza kakuhle. Lusetyenziswa kakhulu kwizakhiwo zekhonkrithi ezixinzelelweyo ukubonelela ngokuqina nokuzinza. Nokuba lusetyenziswa kwiibhulorho, kwizakhiwo okanye kwezinye iiprojekthi zeziseko zophuhliso, olu cingo lwentsimbi luqinisekisa ukuqina nokusebenza okuhlala ixesha elide kwezakhiwo oluzixhasayo. Ukuguquguquka kwalo kunye nokuthembeka kwalo kuyenza ibe yinxalenye ebalulekileyo yoyilo lwanamhlanje.
Ngamafutshane, ucingo lwentsimbi oluxineneyo oluyi-12.7mm luyimveliso esemgangathweni ophezulu ehlangabezana neemfuno zokuqinisa zekhonkrithi exineneyo. Amandla ayo aphezulu, umxholo wayo ophantsi wesalfure kunye ne-phosphorus, kunye neenkcukacha ezahlukeneyo zenza ukuba ilungele ukusetyenziswa kwezixhobo ezahlukeneyo zokwakha. Ngembali yayo ende kunye nokwaziwa kwihlabathi liphela, olu cingo lwentsimbi lube yinxalenye ebalulekileyo kushishino lokwakha, luqinisekisa ukuqina kunye nozinzo lwezakhiwo kwihlabathi liphela.
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.
