Nthawi Yachidule Kuyambitsa Mapaipi Achitsulo

① Delivery state

Delivery state amatanthauza mkhalidwe wa kupindika komaliza kwa pulasitiki kapena kutentha komaliza kwa mankhwala operekedwa. Kawirikawiri, zinthu zomwe zimaperekedwa popanda chithandizo cha kutentha zimatchedwa dziko lotentha kapena lozizira (lozungulira); mankhwala operekedwa ndi kutentha kutentha amatchedwa kutentha kutentha boma, kapena angatchedwe monga normalizing, quenching ndi kutentha, njira, annealing limati. Kutumiza boma liyenera kuwonetsedwa mu mgwirizano mukamayitanitsa.

②Kupereka molingana ndi kulemera kwenikweni kapena kulemera kwake
Kulemera kwenikweni - mankhwalawa amaperekedwa molingana ndi kulemera kwake (pamiyeso);
Theoretical kulemera - popereka, kulemera kwa mankhwala kuwerengedwa molingana ndi kukula mwadzina kwa zinthu zachitsulo. Njira yowerengera ili motere (ngati zinthuzo ziperekedwa molingana ndi kulemera kwake, ziyenera kuwonetsedwa mu mgwirizano)
Kuwerengera chilinganizo cha kulemera kwamalingaliro (kuchuluka kwachitsulo ndi 7.85 kg/dm3) pa mita ya chubu chachitsulo:
W=0.02466 (DS)S
Mu formula:
W——oyerekeza kulemera pa mita ya chubu zitsulo, kg/m;
D--mwadzina kunja awiri a zitsulo chubu, mm;
S---mwadzina makulidwe a khoma lachitsulo chubu, mm.
③Zitsimikizo
Pansi pa zomwe zili mulingo wapano, kuyesa zinthu ndikuwonetsetsa kuti zikutsatira zomwe zili mulingo kumadziwika ngati zitsimikiziro. Chitsimikizo chingagawidwenso kukhala:
A, Zinthu zoyambira zotsimikizira (zomwe zimadziwikanso kuti ndizofunikira). Ziribe kanthu kaya atchulidwa mu mgwirizano ndi kasitomala, muyenera kuyang'ana chinthuchi molingana ndi zomwe zili muyeso, ndikuwonetsetsa kuti zotsatira zoyesedwa zikugwirizana ndi zomwe zili muyeso. Mwachitsanzo, zolemba zamakina, mawonekedwe amakina, kupatuka kwa mawonekedwe, mawonekedwe apamwamba, kuzindikira zowonongeka, kuyesa kuthamanga kwa madzi kapena kuyesa kwaukadaulo monga kukanikiza mopanda phokoso ndi kukulitsa machubu onse ndizinthu zofunika.
B, Mgwirizano umatsimikizira zinthu: kuwonjezera pa zinthu zofunika chitsimikizo, pali akadali "malinga ndi zofunika wogula, zinthu ayenera kukambirana ndi mbali zonse, ndi zinthu ayenera anasonyeza mu mgwirizano" kapena "ngati wogula amafuna ..., ziyenera kusonyezedwa mu mgwirizano”; Makasitomala ena ali ndi zofunika zokhwima pamikhalidwe yotsimikizika yotsimikizika (monga nyimbo, mawonekedwe amakina, kupatuka kwa mawonekedwe, ndi zina zambiri) kapena onjezerani zinthu zoyesa (monga ellipticity, makulidwe a khoma losagwirizana, ndi zina). Pamwamba pa zomwe zili ndi zofunikira ziyenera kukambidwa ndi mbali zonse za wogulitsa ndi wogula, Pangano la Availability Technology liyenera kusainidwa, ndipo zofunikira ziyenera kuwonetsedwa mu mgwirizano. Choncho, zinthu zimenezi amatchedwanso mgwirizano chitsimikizo zinthu. Nthawi zambiri, mitengo yazinthu zomwe zili ndi chitsimikiziro cha mgwirizano ziyenera kuwonjezeka.

④"Batch" mu "batch standard" amatanthauza gawo loyendera, mwachitsanzo. kuyendera gulu. Gulu logawidwa ndi gawo loperekera limatchedwa "delivery batch". Ngati kuchuluka kwa batch yobweretsera kuli kwakukulu, gulu loperekera lingaphatikizepo magulu angapo oyendera; ngati kuchuluka kwa batch yoperekera kuli kochepa, gulu loyendera lingaphatikizepo maulendo angapo obweretsa. Zolemba za "batch" nthawi zambiri zimayendetsedwa motere (onani zofananira):
A, Gulu lililonse liyenera kukhala ndi machubu achitsulo amtundu womwewo (kalasi yachitsulo), chiwopsezo chofananira (thanki) nambala kapena chotenthetsera cha mayi yemweyo nambala, mfundo zomwezo ndi dongosolo lomwelo la kutentha (chiwerengero cha boiler).
B, Ponena za khalidwe mpweya zitsulo chitoliro ndi chubu madzimadzi, mtanda akhoza wapangidwa chitsanzo chomwecho, mfundo chimodzimodzi ndi dongosolo kutentha kutentha (chiwerengero chowiritsa) osiyana boilers (akasinja).
C, Aliyense mtanda welded zitsulo machubu ayenera wopangidwa ndi chitsanzo chomwecho (zitsulo kalasi) ndi mfundo zomwezo.

⑤Chitsulo chamtengo wapatali komanso chitsulo chapamwamba
Mu miyezo ya GB/T699-1999 ndi GB/T3077-1999, chitsulo chomwe chitsanzo chake chinatsagana ndi "A" ndi chitsulo chapamwamba, m'malo mwake, chitsulocho ndi chitsulo chambiri. Chitsulo chapamwamba chimakhala pasadakhale chitsulo chabwino pazinthu zotsatirazi pang'ono kapena kwathunthu:
A, Chepetsani kuchuluka kwa zomwe zikuchokera;
B, Kuchepetsa zili zinthu zoipa (monga sulfure, phosphorous ndi mkuwa);
C, Tsimikizirani ukhondo wapamwamba (zolemba zopanda zitsulo ziyenera kukhala zazing'ono);
D, Tsimikizirani zida zapamwamba zamakina ndi zida zamakono.

⑥Longitudinal njira ndi njira yodutsa
Mu muyezo, longitudinal malangizo ndi kufanana ndi processing malangizo (ie. pamodzi processing malangizo); mayendedwe opingasa ndi ofukula ndi njira yopangira (kuwongolera njira ndi njira ya axial ya chubu lachitsulo).
Pakuyesa kwamphamvu, kupasuka kwa chitsanzo chautali kuyenera kukhala koyima ndi njira yoyendetsera, motero kumatchedwa kupasuka kwapang'onopang'ono; kusweka kwa chitsanzo chodutsa kuyenera kufanana ndi njira yoyendetsera, motero kumatchedwa longitudinal fracture.
