1. Dab tsi yog daim ntawv thov ntawm seamless steel kav hauv kev lag luam aerospace?Hauv kev lag luam aerospace, seamless steel kav yog siv rau hauv kev tsim cov dav hlau, foob pob hluav taws, thiab satellites vim lawv lub zog siab, lub teeb yuag, siab precision, thiab siab -kub tsis kam. Cov ntawv thov muaj xws li: aircraft hydraulic systems (siv siab - siab, siab - precision seamless steel kav xa cov roj hydraulic), cav roj tshuab (siv corrosion-cov kav dej tsis muaj seamless thauj roj), thiab cov khoom siv (siv siab - lub zog alloy seamless kav los txo qhov hnyav thiab txhim kho cov qauv). Cov kav dej seamless steel siv nyob rau hauv kev lag luam aerospace yuav tsum ua tau raws li cov qauv zoo heev, nrog rau qhov tseeb qhov siab, tsis muaj qhov tsis xws luag sab hauv lossis sab nraud, thiab cov khoom siv zoo heev. Cov qib sib xws suav nrog siab -alloy steel kav xws li 40CrNiMoA thiab 30CrMnSiA.
2. Dab tsi yog qhov txawv ntawm seamless steel kav rau kev thauj cov kua thiab cov khoom siv tshuab?Seamless steel kav rau kev thauj cov kua dej (xws li GB / T 8163) feem ntau yog siv los thauj ntau cov kua (dej, roj, roj, thiab lwm yam), yog li lawv tsom rau kev ua haujlwm siab, sealing kev ua tau zoo, thiab corrosion kuj. Lawv cov phab ntsa tuab yog tsim los raws li kev ua haujlwm siab, thiab lawv yuav tsum dhau qhov kev sim hydrostatic kom tsis txhob muaj qhov xau. Seamless steel kav rau cov cuab yeej siv tshuab (xws li GB / T 8162) yog siv los tsim cov khoom siv kho tshuab (shafts, tes tsho, connectors, thiab lwm yam), yog li lawv tsom rau cov khoom siv kho tshuab (lub zog, toughness, thiab hnav tsis kam) thiab qhov tseeb qhov tseeb. Lawv cov phab ntsa tuab yog tsim raws li cov load-cov kabmob uas yuav tsum tau ua, thiab lawv yuav raug ua haujlwm ntxiv (xws li tig, sib tsoo) kom tau raws li qhov yuav tsum tau ua. Tsis tas li ntawd, mechanical structure seamless pipes muaj cov kev xav tau ntau dua rau kev ua tiav thiab qhov ncaj.
3. Yuav khaws thiab thauj cov kav dej seamless steel li cas kom tsis txhob muaj kev puas tsuaj?Txhawm rau kom tsis txhob muaj kev puas tsuaj thaum khaws cia thiab kev thauj mus los ntawm cov kav dej seamless: ua ntej, khaws cov kav dej hauv qhov chaw qhuav, qhov cua, thiab corrosion- lub tsev khaws khoom dawb (tsis txhob raug sab nraum zoov los nag, daus, thiab av noo los tiv thaiv xeb); Thib ob, muab cov kav dej tso rau ntawm lub tiaj tiaj (xws li cov hlua khi ntoo) kom tsis txhob muaj kev sib cuag ncaj qha rau hauv av (tiv thaiv qhov chaw khawb thiab xeb); thib peb, faib thiab faib cov kav dej raws li lawv qhov loj, qib, thiab cov lus qhia tshwj xeeb (tsis txhob sib xyaw cov qib sib txawv kom tsis txhob muaj kev tsis sib haum xeeb, thiab tsis txhob sib tsoo ntau dhau kom tsis txhob deformation); thib plaub, thaum lub sij hawm thauj mus los, siv cov ntaub thaiv npog (xws li zaj duab xis yas los yog canvas) los tiv thaiv cov yeeb nkab nto ntawm khawb thiab kev sib tsoo, thiab kho cov kav dej kom ruaj khov kom tsis txhob zawv zawg thiab puas; thib tsib, tsis txhob thauj cov kav dej nrog cov khoom ntse lossis cov khoom corrosive.
4. Dab tsi yog qib "25Cr2MoVA seamless steel yeeb nkab", thiab nws cov kev siv tseem ceeb yog dab tsi?25Cr2MoVA yog qib siab - alloy seamless steel yeeb nkab qib, belongs rau Cr-Mo-V alloy steel. Nws cov tshuaj muaj pes tsawg leeg muaj xws li: carbon (C) 0.22-0.29%, chromium (Cr) 1.50-1.80%, molybdenum (Mo) 0.90-1.10%, vanadium (V) 0.15-0.30% sib npaug li 0.30%, thiab nick Cov qib no tau zoo heev - kub lub zog, nkag siab, thiab qaug zog tiv thaiv, nrog rau qhov siab tshaj plaws kev pab kub ntawm 570℃. Nws cov ntawv thov tseem ceeb suav nrog - qhov kub thiab txias, siab - siab, thiab cov khoom siv thauj khoom siab hauv cov chaw tsim hluav taws xob (xws li cov kav dej kub siab boiler lub ntsiab chav kav, cov kav dej taub hau), kev lag luam petrochemical (kub kub cov hlab ntsha thiab cov kav dej), thiab cov tshuab hnyav (xws li high-pressure hydraulic cylinders thiab kis tau tus mob).
5. Dab tsi yog qhov kev txhim kho yav tom ntej ntawm seamless steel kav?Txoj kev txhim kho yav tom ntej ntawm cov kav dej seamless steel feem ntau yog tshwm sim hauv plaub yam: thawj, kev ua haujlwm siab (tsim siab- zog, siab- corrosion- tiv taus, thiab siab- kub- cov kav dej seamless kom tau raws li qhov xav tau ntawm kev ua haujlwm hnyav xws li kev sib sib zog nqus {{5} roj av} thiab kev tsim hluav taws xob ntau 6}); thib ob, precision manufacturing (kev txhim kho qhov tseeb qhov tseeb thiab nto tiav los ntawm kev tsim cov thev naus laus zis xws li precision dov thiab kos duab txias, kom tau raws li qhov xav tau ntawm precision machinery thiab aerospace industries); thib peb, ntsuab thiab qis- carbon (optimizing ntau lawm txheej txheem los txo lub zog noj thiab ib puag ncig muaj kuab paug, tsim recycle seamless steel kav); thiab thib plaub, kev kho kom haum (muab cov khoom siv seamless tus kheej raws li cov neeg siv khoom- cov kev xav tau tshwj xeeb, xws li qhov loj me, qib, thiab kev kho saum npoo, kom hloov mus rau ntau hom kev thov).
