(1) Lahlela flange le flange e entsoeng
Flange ea cast e na le sebōpeho le boholo bo nepahetseng, molumo o monyenyane oa ho sebetsa le litšenyehelo tse tlaase, empa o na le liphoso tsa ho lahla (pores, cracks, inclusions);mohaho o ka hare oa ho lahla o futsanehile ka mokhoa o fokolang (haeba e le karolo ea ho itšeha, ho phalla ho hobe le ho feta);
Li-flange tse entsoeng ka maiketsetso hangata li na le khabone e tlase ho feta li-cast flanges 'me ha ho bonolo ho rusa.Forgings e bonolo, e na le sebopeho se teteaneng, 'me e na le thepa e ntle ea mochine ho feta li-flanges;
Mokhoa o sa nepahalang oa ho qhekella o tla boela o bake lithollo tse kholo kapa tse sa lekanang tsa kristale, mapetsong a thata, le litšenyehelo tsa ho qhekella tse phahameng ho feta li-flanges.
Forgings e ka mamella matla a phahameng a ho kuta le a thata ho feta li-castings.
Molemo oa li-castings ke hore li ka hlahisa libopeho tse rarahaneng le ho fokotsa litšenyehelo;
Molemo oa ho forgings ke hore sebopeho sa ka hare se tšoana, 'me ha ho na liphoso tse kotsi tse kang li-pores le li-inclusions ho lahla;
Ho tloha ts'ebetsong ea tlhahiso, phapang pakeng tsa flange ea cast le flange e entsoeng e fapane.Ka mohlala, centrifugal flange ke mofuta oa flange e entsoeng.
Li-centrifugal flanges ke tsa mokhoa o nepahetseng oa ho lahla ho hlahisa li-flange.Ha ho bapisoa le ho lahla lehlabathe le tloaelehileng, sebopeho sa mofuta ona oa ho lahla se setle haholo, 'me boleng bo ntlafala haholo.Ha e na bothata ba ho ba le mathata a kang sebopeho se hlephileng, li-pores le trachoma.
Pele ho tsohle, re hloka ho utloisisa hore na flange ea centrifugal e hlahisoa joang, mokhoa oa ts'ebetso le sehlahisoa sa centrifugal casting ho etsa flange e bataletseng ea welding, e khetholloang ka hore sehlahisoa se sebetsoa ka mehato e latelang:
① Beha tšepe e tala e khethiloeng ka seboping sa motlakase sa maqhubu a mahareng bakeng sa ho qhibiliha, e le hore mocheso oa tšepe e qhibilihisitsoeng o fihle ho 1600-1700 ℃;
② Preheat hlobo ea tšepe ho 800-900 ℃ ho boloka mocheso o sa khaotseng;
③ Qala centrifuge, 'me u tšollele tšepe e qhibilihisitsoeng mohatong oa ① ka har'a hlobo ea tšepe ka mor'a ho futhumatsa pele mohatong ②;
④ Ho lahla ho pholile ka tlhaho ho 800-900 ℃ 'me ho bolokoa metsotso e 1-10;
⑤ Fokotsa ka metsi ho ea haufi le mocheso o tloaelehileng, tlosa 'me u ntše ho lahlela.
