Codsiyada ballaaran
Iyada oo leh sifooyin muuqaal ah oo aad u wanaagsan iyo faa'iidooyin dhaqaale oo la taaban karo.birta ductileayaa si tartiib tartiib ah u noqonaysa agabka doorashada ee goobo badan oo warshado ah, iyadoo si weyn u bedelaysa agab dhaqameedka sida birta been abuurka ah, birta shaambadaysan, alxanka, birta shubka ah ee malleable,birta cawlaniyo bir tuur. Dalka Maraykanka, isbeddelkani waa mid si gaar ah u muuqda. Birta birta ah waxay qabsatay qayb muhiim ah oo suuqa ah waxayna si guul leh u bedeshay qaybo kala duwan oo ka mid ah agabyada aan kor ku soo sheegnay, taas oo muujinaysa awoodeeda codsi ee aan la barbar dhigi karin iyo tartanka suuqa.
| Goobaha Codsiga | Kacitaanka Caadiga ah ee Birta Ductile | Tilmaamaha Waxqabadka | Darajo |
| Dhuumaha biyaha, gaaska iyo saliidda | Tuubooyin sentifugalis ahaan loo tuuray iyo qalabyada, dhexroorkoodu ka yar yahay ama la mid yahay 2600 mm | Cadaadiska cadaadiska, caabbinta daxalka, caabbinta dhulgariir iyo caabbinta ciidda | |
| Baabuur, cagafyo | Crankshaft, camshaft, usha isku xirka, gear, guryeynta faashashka, xajinta usheeda dhexe, guri kala duwan, iwm. | Xiro u adkaysta, daalka adkaysi u leh, xoog sare iyo adayg, oo u adkeysan kara culayska saameeynta ee -40°C | QT900-2 QT800-2 QT700-2 QT600-3 QT400-8 QT450-10 |
| Maraakiibta, gawaarida, matoorada naaftada | Shafka, usha isku xirka, shafka, marshada, xadhkaha dhululubada | Xiro u adkaysta, daal u adkaysta, xoog sare | QT900-2 QT800-2 QT700-2 QT600-3 |
| Mashiinada beeraha | Makiinadu ku talaabsanayso xaaqidda tiirarka, mashiinku harrows, daboolka shafka, gooyayaasha, ilaalada daab, geerka | Adag sare, caabbinta culeyska saameynta | QT400-15 QT450-10 QT500-7 |
| Qaybaha Haydarooliga | Jirka Valve, jirka bamka | Cadaadiska saliidda u adkaysta oo xidho adkaysi | QT400-15 QT450-10 |
| Gaadhi qaada | Gears, shafts, wheel wheels | Xiro u adkaysta, xoog sare | QT900-2 QT800-2 QT700-2 QT600-3 |
Falanqaynta halabuurka wax soo saarka
Marka loo eego qaab-dhismeedka wax-soo-saarka, wax-soo-saarka birta ductile waxay u badan tahay matrix ferrite, oo xisaabiya 60% wadarta guud ee wax-soo-saarka, halka matrix pearlite ay si dhow u raacdo oo ay ku jirto meel. Intaa waxaa dheer, matrixka isku-dhafka ah ee ferrite iyo pearlite ayaa sidoo kale xisaabiya saami aad u badan. Saddexda si wadajir ah waxay ku dhawaad 95% ka yihiin dhammaan wax soo saarka birta ductile, taasoo muujinaysa booska ugu sarreeya ee labadan mitir ee soo saarista birta ductile.
Falanqaynta guryaha farsamada ee heer sare ah
Sababta ugu muhiimsan ee ay birta ductile ay uga dhex muuqan karto maaddooyin badan ayaa ku jira sifooyinkeeda makaanikada ee gaarka ah. Ma laha meel wax-soo-saarka dareenka dhaqanka, iyo qalooca cadaadis-culaysku wuxuu muujinayaa sifooyin isdaba-joog ah oo ka sarreeya xadka saamiga. Dabeecaddani waxay ka timaadaa habdhaqanka gaarka ah ee kubbadaha graphite ee cadaadiska: marka diiqadu ka badato xadka laastikada, inkasta oo kubbadaha graphite ay u muuqdaan inay yihiin qayb ka mid ah matrixka, dhab ahaantii mar dambe ma qalloocinayaan, samaynta nusqaamaha jihada dhererka, taasoo keentay ballaarinta mugga. , balaadhintanna laguma kabo cudud dhinaca dambe ah.
Isbarbardhigga waxqabadka iyo walxaha kale
Birta Cawlan: Dhaqan ahaan, kaliya xoogga xajinta ayaa loo adeegsadaa tilmaame hawleed, iyo darajada ugu sarraysa ayaa leh awood xaddidan (kaliya 350 MPa). Taas bedelkeeda, birta ductile waxay muujinaysaa faa'iidooyin la taaban karo xagga xoogga iyo caagga labadaba.
Birta shubka ah ee la dhayalsan karo: Inkasta oo ay leedahay tilmaameyaal caag ah, haddii ay tahay madow-core, pearlite ama birta malleable ee cad-core, sifooyinkeeda farsamo ee dhamaystiran uma fiicna sida birta ductile.
Birta la tuuro iyo birta qaab dhismeedka: Inkasta oo ay leedahay wax qabad aad u fiican xagga dheereynta jabka ka dib iyo adkeynta saameynta, xoogga wax-soo-saarku uma fiicna sida birta ductile, taasoo sii muujineysa sareynta birta ductile ee codsiyada gaarka ah.
