Cov pa roj carbon steel casting muab lub zog tsis sib xws, hnav tsis kam, thiab cov nqi ua haujlwm rau cov khoom lag luam ua haujlwm nyob rau hauv siab, thermal cycling, lossis abrasive tej yam kev mob. Thaum lub hydraulic manifold ua tsis tiav ntawm 350 bar - lossis lub winch ncej tawg thaum lub sijhawm ua haujlwm offshore crane - lub hauv paus ua rau tsis tshua tsim ib leeg. Nws feem ntau xaiv cov khoom siv, kev tswj hwm microstructural, los yog qhov ruaj khov ntawm qhov sib txawv thaum lub sij hawm casting. Peb tau pom nws thoob plaws peb lub teb chaws: carbon steel castings uas dhau qhov kev sim tensile tab sis tawg hauv kev pabcuam vim tsis muaj qhov tsis pom zoo shrink porosity nyob ze ntawm cov kabmob fillets; lwm tus uas tau ntsib ASTM A27 Qib WCB specs ntawm daim ntawv tab sis warped tom qab kev kho cua sov vim hais tias cov cua txias tsis tau mapped rau seem thickness. Tias yog vim li cas precision carbon steel casting tsis yog hais txog nchuav hlau molten - nws yog hais txog kev tswj kev ruaj khov, validating grain qauv, thiab xauv hauv geometry ua ntej machining txawm pib.
Stainless hlau tiv taus corrosion-tab sis tsis muaj zog tshaj 650 MPa yam tsis muaj nqi ua haujlwm txias. Aluminium txuag qhov hnyav - tab sis qaug zog sai nyob rau hauv cyclic hydraulic loads. Forged steel muaj qhov ntom ntom-tab sis tsis tuaj yeem rov ua dua qhov nyuaj sab hauv ntawm lub piston twj tso kua mis lub tog raj kheej vaj tsev. Carbon steel casting choj uas sib txawv. Qib zoo li ASTM A27 WCB, ASTM A105, thiab ISO 3755 GS-45 xa 485-655 MPa tensile zog, cuam tshuam toughness mus rau -29 ° C, thiab machinability uas txiav lub sij hawm voj voog los ntawm 35% piv rau npib tsib xee alloys. Tseem ceeb heev, carbon steel teb kwv yees rau normalizing, quenching, thiab tempering-ua kom haum rau hardness profiles: 220-260 HB nyob rau hauv bearing nto, 180 HB nyob rau hauv uas tsis yog-tsim flanges, tag nrho los ntawm ib tug casting. Peb tau lees paub qhov no ntawm qhov kev txiav txim tsis ntev los no rau engineering tsheb onboard winch center ncej chais: xuab zeb-cam khwb cia A27 WCB lub cev ua tiav <0.05 hli roundness sib txawv tom qab ua tiav tig-thaum tuav 245 HB core hardness yuav tsum tau rau spline kev koom tes durability.
Tsis yog txhua qhov carbon steel castings ua tau zoo sib npaug. Kev txheeb xyuas qhov tsis ua haujlwm tiag tiag hauv ntiaj teb qhia 72% ntawm thaj chaw ua tsis tiav taug qab mus rau laps hauv ib qho ntawm plaub qhov chaw:
Qhov kev qhuab qhia no piav qhia txog vim li cas peb cov pa roj carbon steel castings rau lub siab li qub tau ua tiav lub rooj zaum rov ua haujlwm tsis pub dhau ± 0.025 hli - qhov tseem ceeb rau kev kaw ntom nti ntawm 700 bar.
Lub twj tso kua mis lub hauv paus tsis yog ib qho slab ntawm hlau. Nws yog ib qho kev vibration-dampening platform nrog 14 tapped qhov, 3 precision dowel bores, thiab nto flatness ≤0.05 hli tshaj 1.2 m². Sim muab qhov kam rau ua yog khib nyiab. Sim tshuab nws los ntawm cov phaj khoom yog kim. Txoj kev daws teeb meem? Kev nqis peev-cam khwb cia carbon steel (ASTM A356) cov duab ntxhib, tom qab ntawd CNC zeb qhov chaw tseem ceeb hauv ib qho kev teeb tsa siv granite-txaj tshuab nrog lub sijhawm them nyiaj thermal. Peb siv txoj kev sib xyaw no rau 68% ntawm peb lub tog raj kheej lub tog raj kheej-txo cov khoom siv raw siv los ntawm 42%, txiav lub sijhawm txhuas los ntawm 11 hnub, thiab tuav bore-rau-flange perpendicularity rau 0.015 hli. Key enablers: fixture-mounted castings nrog machined datum pads, nyob rau hauv-txoj kev sojntsuam xyuas tom qab roughing, thiab kev ntxhov siab-relief annealing * nruab nrab * ntxhib thiab tiav dhau-tsis yog tom qab-casting.

QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. siv cov tshev no txhua hnub. Lawv qhov chaw ISO-raws li hauv Qingdao koom ua ke cov xuab zeb casting, peev casting, multi-axis CNC, thiab lub tshuab nqus tsev kho cua sov nyob rau hauv ib lub ru tsev - tshem tawm cov kev sib koom tes uas ua rau qhov seem txuas ntxiv. Lawv tsis tsuas yog cam khwb cia carbon steel. Lawv engineer nws tus cwj pwm.
Carbon steel casting tseem yog txoj hauv kev ua tau zoo tshaj plaws rau kev ua haujlwm ruaj khov, siab-load muaj cov khoom lag luam-thaum metallurgy, kev tswj cov txheej txheem, thiab kev ntsuas nruj. Cov kauj ruam tom ntej yog tsis xaiv cov khoom siv. Nws yog xaiv leej twg tswj cov kev hloov pauv uas ua rau cov khoom ntawd ua tau.
