①Isimo sokulethwa
Isimo sokudiliva sisho isimo sokuwohloka kokugcina kwepulasitiki noma ukwelashwa kokushisa kokugcina komkhiqizo olethiwe. Ngokuvamile, imikhiqizo ehanjiswa ngaphandle kokwelashwa kokushisa ibizwa ngokuthi isimo esigoqiwe esishisayo noma esidonswa ngokubanda (esigoqiwe); imikhiqizo elethwa ngokwelashwa okushisa ibizwa ngokuthi isimo sokwelashwa kokushisa, noma ingabizwa ngokuthi i-normalizing, quenching and tempering, solution, annealing states. Isimo sokulethwa kufanele sikhonjiswe kwinkontileka lapho uyala.
②Ukuletha ngokwesisindo sangempela noma isisindo sethiyori
Isisindo sangempela — umkhiqizo ulethwa ngokwesisindo esilinganisiwe (ezikalini);
Isisindo sethiyori - lapho uletha, isisindo somkhiqizo sibalwa ngokuya ngosayizi ojwayelekile wezinto zensimbi. Ifomula yokubala imi kanje (uma imikhiqizo ilethwa ngokwesisindo sethiyori, kufanele ikhonjiswe kunkontileka)
Ifomula yokubala yesisindo sethiyori (ukuminyana kwensimbi ngu-7.85 kg/dm3) imitha ngayinye yeshubhu lensimbi:
W=0.02466(DS)S
Kufomula:
W——isisindo sethiyori imitha ngalinye leshubhu lensimbi, kg/m;
I-D---diameter yangaphandle yensimbi, mm;
I-S——ubukhulu obuncane bodonga lweshubhu yensimbi, mm.
③Izimo zokuqinisekisa
Ngaphansi kwezinhlinzeko ezisezingeni lamanje, ukuhlola imikhiqizo nokuqinisekisa ukuthobelana nezinhlinzeko zezinga kwaziwa njengemibandela yesiqinisekiso. Izimo zesiqinisekiso nazo zingahlukaniswa zibe:
A, Izimo zokuqinisekisa eziyisisekelo (ezaziwa nangokuthi izimo ezidingekayo). Kungakhathaliseki ukuthi zicaciswe yini kunkontileka yikhasimende, kufanele uhlole le nto ngokuvumelana nezinhlinzeko ezisezingeni, futhi uqinisekise ukuthi imiphumela yokuhlolwa ihlangabezana nezinhlinzeko ezisezingeni. Isibonelo, ukwakheka kwamakhemikhali, izakhiwo zokukhanda, ukuchezuka kobukhulu, ikhwalithi yendawo, ukutholwa komonakalo, ukuhlolwa komfutho wamanzi noma ukuhlolwa kobuchwepheshe okufana nokucindezela isicaba nesiphetho seshubhu ukunwetshwa yizimo ezidingekayo.
B, Isivumelwano siqinisekisa imibandela: ngaphezu kwemibandela yesiqinisekiso esiyisisekelo, kusekhona “ngokwezimfuneko zomthengi, izimo kufanele kuxoxiswene ngazo nhlangothi zombili, futhi imibandela kufanele iboniswe kwinkontileka” noma “uma umthengi edinga …, kufanele kuboniswe kwinkontileka”; amanye amakhasimende anezidingo eziqinile ezimweni ezijwayelekile zokuqinisekisa (ezifana nokuqanjwa, izakhiwo zemishini, ukuchezuka kwe-dimensional, njll.) noma andise izinto zokuhlola (ezifana ne-ellipticity, ukujiya kodonga olungalingani, njll.). Ngaphezulu kwezinhlinzeko nezimfuneko kufanele kuxoxiswene ngazo yizinhlangothi zombili zomphakeli nomthengi, Isivumelwano Sobuchwepheshe Sokutholakala kufanele sisayinwe, futhi izidingo kufanele ziboniswe kwinkontileka. Ngakho-ke, le mibandela ibizwa nangokuthi izimo zesiqinisekiso sesivumelwano. Ngokuvamile, izintengo zemikhiqizo enemibandela yesiqinisekiso sesivumelwano kufanele zinyuswe.
④"Iqoqo" "kuzinga leqoqo" lisho iyunithi yokuhlola, isb. iqoqo lokuhlola. Iqoqo elihlukaniswe ngeyunithi yokulethwa libizwa ngokuthi "i-delivery batch". Uma inani leqoqo lokulethwa likhulu, iqoqo lokulethwa lingafaka amaqoqo amaningana okuhlola; uma inani leqoqo lokulethwa lilincane, iqoqo lokuhlola lingafaka phakathi amaqoqo amaningana okulethwa. Ukwakheka “kwenqwaba” kuvame ukulawulwa ngale ndlela elandelayo (bona amazinga ahlobene):
A, Iqoqo ngalinye kufanele lakhiwe amashubhu ensimbi emodeli efanayo (ibanga lensimbi), inombolo kabhayela (ithangi) efanayo noma izifudumezi zenombolo kabhayela kamama, ukucaciswa okufanayo kanye nesistimu yokushisa efanayo (inombolo yebhoyili).
B, Mayelana nekhwalithi yepayipi lensimbi ye-carbon steel kanye neshubhu eliwuketshezi, inqwaba ingakhiwa imodeli efanayo, ukucaciswa okufanayo kanye nesistimu yokwelapha ukushisa okufanayo (inombolo ye-boiler) yama-boilers ahlukene (amathangi).
C, Iqoqo ngalinye lamashubhu ensimbi ashiselwe kufanele lakhiwe ngemodeli efanayo (ibanga lensimbi) kanye nokucaciswa okufanayo.
⑤Insimbi yekhwalithi nekhwalithi ephezulu
Ezindinganisweni ze-GB/T699-1999 kanye ne-GB/T3077-1999, insimbi imodeli yayo ehambisana ne-"A" iyinsimbi yekhwalithi ephezulu, ngokuphambene nalokho, insimbi iyinsimbi yekhwalithi evamile. Insimbi yekhwalithi ephezulu ingaphambi kwensimbi yekhwalithi kulezi zici ezilandelayo ngokwengxenye noma ngokuphelele:
A, Yehlisa ububanzi bokuqukethwe kokubhaliwe;
B, Yehlisa okuqukethwe kwezinto eziyingozi (njengesulfure, i-phosphorus nethusi);
C, Qinisekisa ukuhlanzeka okuphezulu (okuqukethwe okungeyona insimbi kufanele kube kuncane);
D, Qinisekisa izakhiwo eziphezulu zemishini kanye nezakhiwo zobuchwepheshe.
⑥Isikhombisi-ndlela se-longitudinal nesiqondiso esiphambene
Esilinganisweni, isiqondiso se-longitudinal sihambisana nesiqondiso sokucubungula (okungukuthi. eduze nendawo yokucubungula); isiqondiso esiphambene siqondile nesiqondiso sokucubungula (isiqondiso sokucubungula i-axial ye-tube yensimbi).
Ngesikhathi sokuhlolwa komthelela, ukuphuka kwesampula ye-longitudinal kufanele kume mpo ngokuqondiswa kokucubungula, ngaleyo ndlela kubizwa ngokuthi ukuphuka okuphambene; ukuphuka kwe-specimen ephambene kufanele kuhambisane nokuqondisa kokucubungula, ngaleyo ndlela kubizwa ngokuthi ukuphuka kwe-longitudinal.
