①Imeko yonikezelo
Imeko yonikezelo ithetha imeko yoguqulo lokugqibela lweplastiki okanye unyango olushushu lokugqibela lwemveliso ezizisiweyo. Ngokuqhelekileyo, iimveliso ezihanjiswa ngaphandle kokunyanga ukushisa zibizwa ngokuba yi-hot-rolled or cold-drawn (rolled) state; iimveliso ezihanjiswa ngonyango lobushushu zibizwa ngokuba yimeko yonyango lobushushu, okanye zinokubizwa njengesiqhelo, ukucima kunye nobushushu, isisombululo, i-annealing states. Imeko yokuhanjiswa kufuneka iboniswe kwikhontrakthi xa iyala.
②Ukuhambisa ngokobunzima bokwenyani okanye ubunzima bethiyori
Ubunzima bokwenene - imveliso ihanjiswa ngokobunzima obulinganisiweyo (kwizikali);
Ubunzima bethiyori - xa uhambisa, ubunzima bemveliso bubalwa ngokobukhulu obuqhelekileyo bezinto zetsimbi. Ifomula yokubala ngolu hlobo lulandelayo (ukuba iimveliso zihanjiswa ngokobunzima bethiyori, kufuneka iboniswe kwikhontrakthi)
Ifomula yokubala yobunzima bethiyori (ubuninzi bentsimbi yi-7.85 kg/dm3) ngemitha yetyhubhu yentsimbi:
W=0.02466(DS)S
Kwifomula:
W——ubunzima bethiyori ngemitha yetyhubhu yentsimbi, kg/m;
D——idayamitha yangaphandle yentsimbi yombhobho, mm;
S--ubukhulu obuqhelekileyo bodonga lwetyhubhu yentsimbi, mm.
③Iimeko zesiqinisekiso
Ngaphantsi kwezibonelelo kumgangatho wangoku, ukuvavanya iimveliso kunye nokuqinisekisa ukuthobela imimiselo yomgangatho kwaziwa ngokuba yimiqathango yesiqinisekiso. Iimeko zesiqinisekiso zinokwahlulwa zibe:
A, Iimeko zesiqinisekiso esisisiseko (esaziwa ngokuba ziimeko eziyimfuneko). Kungakhathaliseki ukuba zichazwe kwikhontrakthi ngumthengi, kufuneka uhlole le nto ngokwemimiselo esemgangathweni, kwaye uqinisekise ukuba iziphumo zovavanyo zihlangabezana nemimiselo esemgangathweni. Umzekelo, ukwakheka kweekhemikhali, iipropathi zoomatshini, ukutenxa komgangatho, umgangatho womphezulu, ukubonwa komonakalo, uvavanyo loxinzelelo lwamanzi okanye imifuniselo yetekhnoloji efana nokucofa isicaba kunye nokwandiswa kwetyhubhu zonke ziyimfuneko.
B, IsiVumelwano siqinisekisa iimeko: ngaphezu kweemeko zesiqinisekiso ezisisiseko, kusekho "ngokweemfuno zomthengi, iimeko kufuneka zixoxwe ngamacala omabini, kwaye imiqathango kufuneka iboniswe kwisivumelwano" okanye "ukuba umthengi ufuna ..., ifanele iboniswe kwikhontrakthi”; abanye abathengi baneemfuno ezingqongqo kwisiqinisekiso esisisiseko seemeko (ezifana nokuqamba, iipropathi zoomatshini, ukutenxa komgangatho, njl. njl.) Ngaphezulu kwezibonelelo kunye neemfuno kufuneka kuxoxwe ngazo ngamacala omabini omthengisi kunye nomthengi, i-Availability Technology Agreement kufuneka isayinwe, kwaye iimfuno kufuneka ziboniswe kwikhontrakthi. Ngoko ke, le miqathango ikwabizwa ngokuba yimiqathango yokuqinisekisa isivumelwano. Ngokubanzi, amaxabiso eemveliso ezinemiqathango yesiqinisekiso sesivumelwano kufuneka anyuswe.
④"Ibhetshi" "kwibhetshi umgangatho" ithetha iyunithi yokuhlola, okt. ibhetshi yokuhlola. Ibhetshi eyahlulwe yiyunithi yokuhanjiswa ibizwa ngokuba yi "delivery batch". Ukuba inani lebhetshi yokuhanjiswa likhulu, ibhetshi yokuhambisa inokubandakanya iibhetshi ezininzi zokuhlola; ukuba inani lebhetshi yokuhanjiswa lincinci, ibhetshi yokuhlola inokubandakanya iibhetshi ezininzi zokuhanjiswa. Iziqulatho “zebhetshi” zihlala zilawulwa ngolu hlobo lulandelayo (jonga imigangatho enxulumeneyo):
A, ibhetshi nganye kufuneka iqulunqwe iityhubhu intsimbi imodeli efanayo (ibakala Steel), kwibhoyila efanayo (itanki) inombolo okanye omnye umama kwibhoyila inombolo izifudumezi, iinkcukacha ezifanayo kunye nenkqubo yonyango ubushushu efanayo (inombolo boiler).
B, Ngokubhekiselele kumbhobho wentsimbi yekhabhoni esemgangathweni kunye netyhubhu yolwelo, ibhetshi inokuqulunqwa imodeli efanayo, ingcaciso efanayo kunye nenkqubo yonyango yobushushu efanayo (inombolo yebhoyila) yeebhoyila ezahlukeneyo (iitanki).
C 、 Ibhetshi nganye yeetyhubhu zentsimbi ezidityanisiweyo kufuneka zenziwe imodeli efanayo (ibakala lentsimbi) kunye neenkcukacha ezifanayo.
⑤Intsimbi esemgangathweni kunye nentsimbi ephezulu
Kwimigangatho ye-GB / T699-1999 kunye ne-GB / T3077-1999, insimbi imodeli yayo ehamba kunye ne "A" yintsimbi ephezulu, ngokuchaseneyo, insimbi yintsimbi eqhelekileyo. Intsimbi yomgangatho ophezulu iphambi komgangatho wentsimbi kule miba ilandelayo ngokuyinxenye okanye ngokupheleleyo:
A, Nciphisa uluhlu lwesiqulatho sokuqulunqa;
B, Ukunciphisa umxholo wezinto ezinobungozi (ezifana nesulfure, i-phosphorus kunye nobhedu);
C, Qinisekisa ucoceko oluphezulu (umxholo wokubandakanywa okungezona isinyithi kufuneka ube mncinci);
D, Qinisekisa iipropathi zoomatshini eziphezulu kunye neempawu zobuchwepheshe.
⑥Isalathiso sexesha elide kunye nesalathiso esinqamlezayo
Kumgangatho, ulwalathiso lwe-longitudinal luhambelana ne-process direction direction (okt ecaleni kwendlela yokucubungula); isalathiso esinqamlezileyo sithe nkqo kunye nesalathiso sokusetyenzwa (isalathiso senkqubo ye-axial yetyhubhu yentsimbi).
Ngexesha lovavanyo lwempembelelo, ukwaphuka kwesampulu yelongitudinal kufuneka kume nkqo kunye nesalathiso sokusetyenzwa, ngaloo ndlela kubizwa ngokuba yi-transverse fracture; Ukwaphuka kwesampulu enqamlezileyo kufuneka ihambelane nesalathiso sokusetyenzwa, kungoko kubizwa ngokuba yi-longitudinal fracture.
