Okugabanya ebbugumu-ekyuma ekiziyiza .

Okugabanya nga aloy elementi ebirimu .
1) low-ekyuma kya kaboni: Wakati mu kyuma ng’ekyo kirimu oba tekitera kubaamu bintu bya aloy ebirala, okutwalira awamu kaboni waakyo tasukka 0.2%.
2) Ekyuma ekiziyiza ebbugumu erya aloy ekitono: Mu kyuma eky’ekika kino kirimu ekintu kimu oba ebiwerako eby’ekika kya aloy, naye ebirimu si bingi, omuwendo gwonna ogw’ebintu bya aloy ebisangibwa mu kyuma eky’awamu tebisukka 5%, kaboni alimu tasukka 0.2%.
3) Ekyuma ekigumira ebbugumu eringi: Mu kika kino eky’ebintu ebikozesebwa mu kukola aloy, okutwalira awamu elementi ya alloy esukka 10%, oba wadde nga waggulu nga 30%.
Okusinziira ku mpisa z’okugabanya ebyuma .
1) Ekyuma ekiziyiza obuwuka obuleeta obulwadde (oba okuziyiza ebbugumu si kyuma kya ddiba): Ekyuma eky’ekika kino ku bbugumu erya waggulu (okutwalira awamu mu 550~1200℃) kirina okuziyiza okulungi okw’okwokya n’okuziyiza okukulukuta okw’ebbugumu eringi, era kirina amaanyi agamu ag’ebbugumu eringi. Ekozesebwa okukola ebitundu eby’ekika kya kyokya ebya buli ngeri n’ekyuma ekikyusa ebbugumu, okukola akatale k’okwokya ebbugumu mu bbugumu, crane ya boiler, wansi w’ekikoomi n’oluguudo lwa roller ne payipu y’ekikoomi. Omulimu gw’okuziyiza obuwuka obuleeta obulwadde (antioxidant performance) gwe muwendo omukulu, era ekitundu kyennyini tekirina puleesa nnene.
2) Ekyuma amaanyi g’ebbugumu: Ku bbugumu erya waggulu (ebiseera ebisinga 450~900℃) esobola okugumira okunyigirizibwa okw’enjawulo n’okuziyiza okw’okwokya okulungi ennyo, okuziyiza okukulukuta kw’omukka ogw’ebbugumu eringi, ebiseera ebisinga era kyetaagisa okugumira okunyigirizibwa okukyukakyuka okw’ekiseera. Kitera okukozesebwa nga rotor ne blade ya steam turbine ne gas turbine, superheater ya boiler, bolt ne spring nga zikola ku bbugumu erya waggulu, inlet ne exhaust valve ya internal combustion engine, petroleum hydrogenation reactor, etc.
Okusinziira ku nkozesa enkulu ey’okugabanya ebyuma .
Industrial furnace heat-ekyuma ekiziyiza: Ng’oggyeeko riyakita, ekyuma ekikola amasannyalaze, ekikoomi ky’amakolero eky’amafuta, mu kyuma, ebyuma, ebizimbisibwa, amakolero amatono n’amakolero amalala, agakozesebwa ennyo ng’ekikyusa ebbugumu, ekyuma ekifumbisa ekikoomi, ttanka eraga n’ebitundu ebirala ebiziyiza 1} 1} lest steel steel steel steel stell steel 1} least steel steel 1} 1} 1}. ebyuma ebisuuliddwa. All kinds of annealing furnace cover, continuous heating tank, radiation pipe, charging frame, chain belt of controllable atmosphere continuous heating furnace, mostly use 310 (0Cr25Ni20) or 3Cr24Ni7SiNRe, 2Cr25Ni13 steel, etc. A large number of furnace bottom roller and radiation pipe in the continuous heating furnace and heat treatment furnace also use high alloy heat resistant steel centrifugal casting pipe, Commonly used brands are 0Cr18Ni9, 00Cr18Ni9, 1Cr18Ni9Ti, 0Cr17Ni12Mo2, 00Cr17Ni12Mo2, 3Cr24Ni7SiNRe, 0Cr23Ni13,1Cr20Ni14, Cr25Ni20Si2, 00Cr10Ni20Mo6Cu6, 4CR25NI35NBW, 70CRMOVBRE, 4CR28NI48W5SI2, 3CR26NI4MNMORE NE . Mu makolero ga seminti, omuwendo omunene ogw’ebbugumu-enjegere z’ekyuma ezigumira mu kikoomi kya seminti omubisi pre-epulati ey’omu ttaka, ey’ekisenge mu kikoomi ekinene ekya seminti, ebbugumu-ebitundu by’ebyuma ebiziyiza, nga 3CR24NI7SINRE, 1CR20NI14, CR25NI25ni2, etc24ni7sinre
