Umbhobho wesikwere ligama lombhobho wesikwere nombhobho ongxande, oko kukuthi, umbhobho wentsimbi onobude obulinganayo nobungalinganiyo emacaleni. Wenziwe ngentsimbi egoqwe ngemicu emva kokulungiswa kwenkqubo. Ngokubanzi, umbhobho wentsimbi uyasuswa, ulinganiswe, ugoqwe kwaye udityaniswe ukuze wenze umbhobho ongqukuva, uze ugoqwe ube ngumbhobho ongqukuva ukusuka kumbhobho ongqukuva, uze unqunyulwe ube ngubude obufunekayo.

1. Ukuphambuka okuvumelekileyo kobukhulu bodonga lombhobho wesikwere akumele kudlule i-plus okanye i-minus 10% yobukhulu bodonga obuqhelekileyo xa ubukhulu bodonga bungadluli kwi-10mm, kunye okanye i-minus 8% yobukhulu bodonga xa ubukhulu bodonga bungaphezulu kwe-10mm, ngaphandle kobukhulu bodonga lweekona kunye neendawo zokuwelda.

2. Ubude obuqhelekileyo bokuhanjiswa kwepayipi yesikwere esingunxande yi-4000mm-12000mm, uninzi lwayo yi-6000mm kunye ne-12000mm. Ityhubhu engunxande ivumelekile ukuhambisa iimveliso ezimfutshane nezingenazingqinisiso ezingaphantsi kwe-2000mm, kwaye ingahanjiswa ngendlela yetyhubhu yojongano, kodwa iDemander iya kuyinqumla ityhubhu yojongano xa iyisebenzisa. Ubunzima beemveliso zegeyiji emfutshane kunye neemveliso zegeyiji ezingazingqinisiyo aziyi kudlula i-5% yomthamo wokuhanjiswa uwonke. Kwiityhubhu zesikwere ezinobunzima obungaphezulu kwe-20kg / m, aziyi kudlula i-10% yomthamo wokuhanjiswa uwonke.

3. Iqondo lokugoba lombhobho ongxande wesikwere aliyi kuba ngaphezu kwe-2mm ngemitha, kwaye iqondo lokugoba lilonke aliyi kuba ngaphezu kwe-0.2% yobude bubonke

Ngokwenkqubo yemveliso, iityhubhu zesikwere zahlulwe zaba ziityhubhu zesikwere ezingenamthungo ezigoqwe ngobushushu, iityhubhu zesikwere ezingenamthungo ezitsalwe ngokubandayo, iityhubhu zesikwere ezingenamthungo ezikhutshiweyo kunye neetyhubhu zesikwere ezidityanisiweyo.

Umbhobho wesikwere odibeneyo wahlulwe waba

1. Ngokwenkqubo – ityhubhu yesikwere yokuwelda ye-arc, ityhubhu yesikwere yokuwelda yokumelana (i-frequency ephezulu kunye ne-frequency ephantsi), ityhubhu yesikwere yokuwelda yegesi kunye netyhubhu yesikwere yokuwelda yesitovu

2. Ngokwe-weld - umbhobho wesikwere odibeneyo othe tye kunye nombhobho wesikwere odibeneyo ojikelezayo.

Ukuhlelwa kwezinto

Iityhubhu zesikwere zahlulwe zaba ziityhubhu zesikwere zentsimbi yekhabhoni eqhelekileyo kunye neetyhubhu zesikwere ze-alloy eziphantsi ngokwezinto ezisetyenzisiweyo.

1. Intsimbi yekhabhoni eqhelekileyo yahlulwe yaba yi-Q195, Q215, Q235, SS400, 20# intsimbi, 45# intsimbi, njl.

2. Intsimbi ye-alloy ephantsi yahlulwe yaba yi-Q345, 16Mn, Q390, St52-3, njl.

Udidi oluqhelekileyo lwemveliso

Ityhubhu yesikwere yahlulwe yaba yityhubhu yesikwere esemgangathweni yesizwe, ityhubhu yesikwere esemgangathweni yaseJapan, ityhubhu yesikwere esemgangathweni yaseBritane, ityhubhu yesikwere esemgangathweni yaseMelika, ityhubhu yesikwere esemgangathweni yaseYurophu kunye netyhubhu yesikwere engeyomgangatho ngokwemigangatho yemveliso.

Ulwahlulo lwemilo yecandelo

Iipayipi zesikwere zihlulwe ngokwemilo yecandelo:

1. Ityhubhu yesikwere yecandelo elilula: ityhubhu yesikwere, ityhubhu yoxande.

2. Ityhubhu yesikwere enecandelo elintsonkothileyo: ityhubhu yesikwere emile okwentyatyambo, ityhubhu yesikwere evulekileyo, ityhubhu yesikwere erhangqiweyo kunye netyhubhu yesikwere emile okwekhethekileyo.

Ulwahlulo lonyango lomphezulu

Iipayipi zesikwere zahlulwe zaba ziipayipi zesikwere ezifakwe i-hot-dip galvanized, iipayipi zesikwere ezifakwe i-electro galvanized, iipayipi zesikwere ezifakwe ioyile kunye neepayipi zesikwere ezifakwe i-pickle ngokwendlela esetyenziswa ngayo umphezulu.

Sebenzisa udidi

Iityhubhu zesikwere zahlulwe ngokwendlela ezisetyenziswa ngayo: iityhubhu zesikwere zokuhombisa, iityhubhu zesikwere zezixhobo zezixhobo zoomatshini, iityhubhu zesikwere zoshishino loomatshini, iityhubhu zesikwere zoshishino lweekhemikhali, iityhubhu zesikwere zesakhiwo sentsimbi, iityhubhu zesikwere zokwakha iinqanawa, iityhubhu zesikwere zemoto, iityhubhu zesikwere zemiqadi yentsimbi kunye neekholamu, kunye neetyhubhu zesikwere zeenjongo ezikhethekileyo.

Ulwahlulo lobukhulu bodonga

Iityhubhu eziziingxande zahlulwe ngokobukhulu bodonga: iityhubhu eziziingxande ezinde kakhulu, iityhubhu eziziingxande ezinde kunye neetyhubhu eziziingxande ezinde. Umzi-mveliso wethu uneteknoloji yemveliso ethengiswayo, kwaye unobuchule kakhulu. Wamkelekile abahlobo bamazwe ngamazwe ukuba badibane nathi. Siza kuzama konke okusemandleni ethu ukuhlangabezana neemfuno zenu ezahlukeneyo.
