① mkhalidwe wobereka
Zimatanthawuza mkhalidwe wa kusinthika kwa pulasitiki komaliza kapena chithandizo chomaliza cha kutentha kwa mankhwala operekedwa. Kawirikawiri, kutentha kotentha kapena kuzizira (kugwedeza) dziko kapena kupanga dziko: kutentha kwa kutentha kwa kubereka pambuyo pa chithandizo cha kutentha, kapena moto wokhazikika (wachibadwa), kusintha kwa khalidwe, yankho lolimba, dziko la annealing malinga ndi gulu la chithandizo cha kutentha.Pamene mukuyitanitsa, chikhalidwe chobweretsera chidzawonetsedwa mu mgwirizano.
② imaperekedwa ndi kulemera kwenikweni kapena kulemera kwake
Kulemera kwenikweni-Pakubereka, kulemera kwa mankhwala kumaperekedwa ndi kulemera (kulemera) kulemera;
Kulemera kwachidziwitso-Kulemera kwa mankhwala ndi kulemera kowerengedwa kuchokera ku kukula kwadzina kwa chitsulo.Chiwerengero chowerengera chili motere (chofunika molingana ndi kulemera kwa chiphunzitso, chidzasonyezedwa mu mgwirizano): kulemera kwa chiphunzitso pa mita (kuchuluka kwachitsulo). ndi 7.85 kg/dms3) chilinganizo chowerengera:
Mtundu w = (DS) S: ongoyerekeza kulemera kwa T chitoliro chimodzi zitsulo pa mita, kg/m;m'mimba mwake mwadzina akunja a D-zitsulo chitoliro, m: s mwadzina khoma makulidwe a chitoliro chimodzi zitsulo, m.
③ chitsimikizo zinthu
Malinga ndi mulingo wapano wa tsiku lowunikira ndikuwonetsetsa kuti mulingowo watsatiridwa, wotchedwa ma guarantee conditions.Makhalidwe a chitsimikizo amagawidwanso:
A. Basic guarantee conditions (omwe amadziwikanso kuti compulsory guarantee conditions). Kaya zasonyezedwa mu mgwirizano kapena ayi. Miyezo yonse yaukadaulo idzathawa kuwunika, ndikuwonetsetsa kuti zotsatira zoyendera zikugwirizana ndi zomwe zaperekedwa.Monga chemical composition, mechanical katundu, kupatuka kwa kukula, mawonekedwe apamwamba ndi kuzindikira zolakwika, kuyesa kwa hydraulic kapena fan fan kapena kukulitsa 1 1 ndi kuyesa kwina kwa machitidwe, ndizofunikira.
B. Chitsimikizo cha mgwirizano wa mgwirizano: Kupatulapo zitsimikiziro zoyambira muyeso, pali ” zokambirana pakati pa maphwando awiriwo molingana ndi zomwe wofunayo akufuna. Ndipo zindikirani mu mgwirizano?kapena ” pamene wogula akufuna.Fufuzani…, ziyenera kuwonetsedwa mu mgwirizano ";makasitomala ena, zofunika chitsimikizo zofunika monga zikuchokera, makina katundu, kupatuka kukula, etc.) kapena zinthu zina kuyendera (monga zitsulo chitoliro elliptical, m'lifupi khoma makulidwe) mawu pamwamba ndi zofunika, poyitanitsa, kupereka ndi amafuna maphwando adzakambirana, kusaina mgwirizano waukadaulo woperekera ndikuwuwonetsa mu mgwirizano.Chifukwa chake, izi zimadziwikanso kuti zitsimikiziro za mgwirizano.Pazinthu zomwe zili ndi zitsimikiziro za mgwirizano, mtengo uyenera kuwonjezeka.
④ lembani malangizo kapena ndemanga
"Mgulu" muyeso umatanthawuza gawo loyang'anira, ndilo gulu loyendera.Ngati gulu la gulu loperekera, lotchedwa batch yobweretsera. Ndi yaying'ono, gulu loyang'anira litha kugawidwa m'magulu angapo obweretsera. Mapangidwe a "gulu" nthawi zambiri amakhala ndi izi (onani zofunikira):
A. Gulu lirilonse lidzapangidwa ndi mapaipi achitsulo omwe ali ndi nambala yamtundu womwewo (kalasi yachitsulo), nambala ya ng'anjo yofanana (thanki) kapena nambala ya ng'anjo ya mayi yemweyo, ndondomeko yofanana ndi njira yochizira kutentha (nthawi za ng'anjo).
B. Kwa mapaipi apamwamba kwambiri a carbon steel structural mapaipi ndi mapaipi amadzimadzi, ng'anjo zosiyanasiyana (matangi) amatha kukhala ndi nambala yamtundu womwewo, mawonekedwe omwewo komanso njira yochizira kutentha (nthawi za ng'anjo).Mapangidwe a chitoliro chachitsulo.
C. Gulu lililonse la chitoliro chachitsulo chowotcherera lidzakhala lopangidwa ndi chitoliro chachitsulo chokhala ndi kalasi yofanana (kalasi yachitsulo) ndi ndondomeko yomweyo.
⑤ chitsulo chamtengo wapatali ndi chitsulo chapamwamba kwambiri
M'miyezo ya GB / T699-1999 ndi GB / T3077-1999, mtundu wake wabwereranso ndi "A", chifukwa cha chitsulo chapamwamba, apo ayi chitsulo chapamwamba kwambiri. Chitsulo chapamwamba chimakhala chapamwamba mwa zina kapena zonsezi:
A. Chepetsani kuchuluka kwa zinthu:
B. Chepetsani zomwe zili zovulaza (monga kutuluka, phosphorous ndi chitsulo):
