Njira zodzitetezera pakugwiritsa ntchito njerwa zosalephereka zopumira

Kuyenga m’ng’anjo yakhala gawo lofunikira pakupanga kwazitsulo kwamakono, ndipo kuwomba kwa argon kuchokera pansi pa ladle ndichinthu chofunikira kwambiri pakuyeretsedwera kunja kwa ng’anjo, ndipo njerwa yololeza yolowetsa mpweya ndiyofunikira kwambiri pozindikira izi, ndi opanga zitsulo amakhudzidwa kwambiri. Njerwa yabwino yolowetsa mpweya iyenera kukhala ndi mawonekedwe a moyo wautali wautali, kuwombera bwino pansi, kopanda (kochepa), kotetezeka komanso kodalirika. Njerwa zomwe zimapumira pano zimaphatikizaponso mtundu wodulidwa ndi mtundu wopanda malire. Kutalika ndi kugawa kwa masileti amtundu wa njerwa zomwe zimatha kulowerera zimayenera kupangidwa molingana ndi kuthekera kwa ladle, mtundu wachitsulo chosungunuka komanso kuloleza kwa mpweya, chifukwa chake kupanga kumakhala kovuta; Posachedwa, kuchuluka kwakukulu kogawidwa mosavomerezeka kudzera pama pores kumapangidwa, ndipo njira yopangira ndiyosavuta.

Njerwa yolimbana ndi mafuta yololeza yololeza imagwiritsa ntchito kapangidwe kazipangizo kamene kamakhala ndi mpweya wolimba kwambiri komanso zida zolimba kwambiri: malo ogwirira ntchito njerwa ndi mapangidwe odana ndi seepage, ndipo chida chachitetezo chimatenga chidutswa chodulira . Njira yodulira mpweya ikawonedwa, imawonetsa kutalika kwakutali kwa njerwa zololeza mpweya sikokwanira, ndipo njerwa yomwe imaloleza mpweya imayenera kusinthidwa.

Chithunzi 1 Njerwa yopumira

Mukamayendetsa ndikukhazikitsa njerwa zopumira, onetsetsani kuti ulusi wa chitoliro chachitsulo sichinawonongeke, kuti mupewe kulumikizana kwa chitoliro ndi kutuluka kwa mpweya, zomwe zingakhudze kuthamanga kwa argon ndikuwombera; onetsetsani kuti chitoliro chachitsulo chachitsulo sichilowa m’fumbi ndi sundries, ndi zina .; onetsetsani kuti njerwa yopumira Imagwira ntchito osaphimbidwa ndi matope amoto kapena zida zina kuti mupewe kuwomba kosalephera. Pakukhazikitsa kapena kugwiritsira ntchito, onetsetsani kuti payipayo yolumikizidwa mwamphamvu ndipo sikutuluka mpweya, apo ayi kukakamiza kwa argon sikokwanira, zomwe zingakhudze zomwe zingayambitse ndikupangitsa kuti muyeso wotsikawo utsike.

Wotembenuzirayo akagundidwa, aloyi amawonjezeredwa molawirira kwambiri ndipo chitsulo chosungunuka mu ladle chimakhala chotsika kwambiri, kutsika kwamphamvu ndi kolimba kwa malo osungunuka a aloyi kumapangitsa kuti pakhale njerwa zopanda pake. Kuphatikiza apo, kuwonjezeranso msanga kwa alloying kumabweretsa kutsika kotsika pansi pa ladle; ngati ntchito yoliza ya argon siyokhazikika, ndipo mpweya wawukulu wa argon sunayendetsedwe munthawi pambuyo pogogoda, ndikosavuta kuyipangitsa kukhala kovuta kuphulika koyambirira koyenga.

Kuphatikizika kwakukulu pansi pa ladle, madothi ambiri pa intaneti, kutaya slag kwakanthawi pambuyo pomaliza kuthira zitsulo, kukonza kotentha osayeretsa njerwa, nthawi yayitali yotentha ya ladle, kutentha pang’ono kwa chitsulo chosungunuka, ndi zina zambiri. .

Chithunzi 2 Njerwa zopumira zopangira utsi wa aluminium

Monga katswiri wopanga zida zotsutsa, kampani yathu yakhala ikukula, ndikupanga ndikugulitsa njerwa zotsutsana ndi mafuta kwa zaka zambiri. Kugwiritsa ntchito njerwa zotsutsana ndi mpweya sikuti kumangokhala ndi chitetezo chokwanira, komanso kumathetsa zolephera za nthawi yayitali kuposa njerwa yopumira, ndipo zimalimbikitsa kwambiri ntchito yopanga chitsulo.
