Isalathiso senkqubo yemveliso ye-isothermal ye-isothermal inyibilikisi eUnited States

Kukho umahluko kwiipropathi zoomatshini phakathi kwe-isothermal ye-isothermal yentsimbi ye-United States kunye ne-isothermal gucile iron. Umzekelo, i-isothermal gucile i-numbile e-china iqala ngeepropathi zoomatshini ezingama-900 megapascals, ngelixa eUnited States iqala ngo-750 megapascals ezingama-750. Ukongeza, kukho izinto ezahlukileyo ngokwemigaqo yenkqubo yenkqubo, ukunyibilika, kunye nonyango lobushushu. Masijonge ezi ndawo zahlukile kwikhaya lethu kwaye ubone ukuba kukho naziphi na iindawo esinokufunda kuzo. Amabakala asemgangathweni we-isothermal yentsimbi yentsimbi e-United States ikakhulu isekwe ikakhulu kwi-ASTM A897, kwaye ezona ziqhelekileyo zezi zilandelayo:

Ukongeza, kukho amabakala aqhelekileyo anjengeBakala 1-6. Yintoni umahluko ekuqulunqwa kwe-isothermal gucile huctile phakathi kwe-China ne-United States? Kumgangatho we-American Astm A897, ubume obuqhelekileyo beekhemikhali ze-isothermal yentsimbi efana neBanga lesi-2 kunye neBanga le-5 le-5,5% ye-Mybdenum, ≤ 2.0% i-iron yentsimbi, kunye ne-93% intsimbi. Ukuqulunqwa kwekhemikhali ye-Chinese Qt1050-6 kunye namanye amabakala e-Isthermal ye-Isthermal i-3.5% -0% ye-pholboron, i-0.0.6% i-pholbon, 0.5% -0.5% -0.5% -0.25% molybdenum, kunye ne-0.02% -0.05% umhlaba onqabileyo. Ukuthelekisa ibonisa ukuba umxholo wekhabhoni wezinto eziphambili ilungiswe malunga ne-3.7% kwimigangatho yamabanga athile aseMelika, ngelixa umxholo wekhabhoni wamabakala ohlukeneyo e-China uyahluka phakathi kwamabakala athile kunye neemfuno zomsebenzi. Umxholo weSilicon: Ngokubanzi malunga ne-2,5% eUnited States kunye ne-2.2% -2.6% eTshayina, eguquguqukayo ngakumbi. Umxholo we-manganese wezinto ze-Alloy: Ngokubanzi, yi-0.28% e-United States, ngelixa e-China, umxholo ubukhulu becala iphakathi kwe-0.2%, kunye ne-United States izinzile ngakumbi. Umxholo wobhedu: I-United States ichaza umxholo wobhedu lwe-0.80%, i-China ngokubanzi iphakathi kwe-0.3% -0% okanye i-0.4% -0.6%, i-0.6% ye-Clearing eTshayina. Umxholo we-molybdenum: 0.00% -0.25% kwi-United States kunye ne-0.15% -0.25% eTshayina. I-China inolawulo oluthile olungakumbi lomxholo we-molybdenum. Umxholo weNickel: I-United States ivumela umxholo we-NCEKCE ukuze ube ≤ 2.0%, ngelixa i-China ayichazi ngokucacileyo imigangatho ye-NCEKCEL kwimigangatho yokwenziwa kweekhemikhali kwimigangatho ye-isothermal. I-Magnesium yeNqaku lokuPhakamisa: I-China ngokubanzi ilawula umxholo we-magnesium nge-0.03% -0% -0.05%, ngelixa umgangatho wase-US ungachazanga ngokucacileyo umxholo wezinto eziphambili zokuphuma. Umxholo womhlaba onqabileyo: i-China ichaze ngokucacileyo ukuba umxholo womhlaba onqabileyo ungaphakathi kwe-0.02% kwaye i-0.05%, ngelixa iUnited States ayikhange iwakhange.

Uthini umahluko kwiinkqubo zonyango lwe-SURFAL ye-isothermal ductile phakathi kwe-China ne-United States?

Iqondo lokushisa inqanaba le-Austeriting: e China, intsimbi ye-ductile ngokubanzi ishushu kakhulu kwi-850-950 ℃. EUnited States, xa bevelisa i-120-90-2, iqondo lobushushu lokufudumeza liyi-880-900 ℃, kunye neqondo lobushushu eliqhelekileyo yi-820-860 ℃.

Ixesha lokufakelwa: I-China ihlala igcina i-Intermating iiyure eziyi-1-2, ngelixa iUnited States imisela i-interm kangangeyure ezingama-25mm yonke i-25mm yodonga ngokusekwe kubungakanani bomhlaba kunye nobungakanani bokuphosa.

Iqondo lokupholisa ngexesha lokuphumelela kwinqanaba: IChina igxininisa ukupholisa ngokukhawuleza kuluhlu lwamaqondo obushushu okuthintela ukubekwa kwe-Pearls kwi-SEARLINS KWI-MOSTERSE YOKWENZA UMSEBENZI WOKUGQIBELA WOKUGQIBELA WOKUGQIBELA. Xa ucekeceke eUnited States, iingcinga zipholile ngokukhawuleza ekucimeni kwemithombo yeendaba ezinje ngeoyile okanye ityuwa etyhidiweyo ukufumana isakhiwo seMa Martianici. I-Conech: Ukuhlambela ityuwa kuqhelekile isetyenziswa njengeyona ndlela iphakathi e-China, enjengokusebenzisa ifomula ye-witrate ye-55% ye-potassium ye-titsium kunye ne-45% sodium nitite. I-United States isebenzisa ukucima imithombo yeendaba efana neoyile okanye ityuwa etyhidiweyo.

I-SOERMMAL DOFERMAL ISETYENZISE IXESHA LOKUGQIBELA EUnited States, xa bevelisa intsimbi ye-gucile enje nge-120-90-2 yokupeyinta, ubushushu bobushushu buhlala phakathi kwe-250-350 ℃. Yokuphoxeka okufuna ukusebenza okuphezulu kakhulu, ubushushu obungatshatanga abangama-500-600 ℃ bungasetyenziswa.

Ixesha leSothermal: I-China igcina eli qondo lobushushu le-1.5-3.5, ngelixa umlinganiso kunye nexesha lokufakwa kunye nokufakwa kwi-United States ngokubanzi.

Inqanaba lokupholisa e-China: Ihlala ipholile ukuba ipholile kubushushu begumbi. Indlela yokupholisa emva kokuba umlinganiso e-United States ihlala ipholile okanye ipholise.
