Iav Log rau Gear Hobbing Tshuab Ua los ntawm Cov Hlau Casting Tshwj Xeeb

(1) Low-pressure casting (low-pressure casting) Low-pressure casting: yog hais txog ib txoj hauv kev uas cov hlau ua kua tau ntim nrog pwm nyob rau hauv lub siab tsis tshua muaj siab (0.02 ~ 0.06 MPa) thiab crystallized nyob rau hauv siab los tsim ib tug casting. Cov txheej txheem ntws: Cov yam ntxwv tshwj xeeb: 1. Lub siab thiab ceev thaum lub sij hawm nchuav tuaj yeem hloov kho, yog li nws tuaj yeem siv rau ntau yam pwm pwm (xws li pwm hlau, xuab zeb pwm, thiab lwm yam), casting ntau yam alloys thiab castings ntawm ntau yam. qhov ntau thiab tsawg; 2. Siv hauv qab Txhaj hom filling, molten hlau filling yog ruaj khov, tsis muaj splashing, uas tuaj yeem zam qhov kev nkag ntawm cov pa roj thiab yaig ntawm phab ntsa thiab cov tub ntxhais, uas txhim kho qhov tsim nyog tus nqi ntawm cov casting; 3. Lub casting crystallizes nyob rau hauv siab, cov qauv ntawm cov casting yog ntom, thiab cov qauv ntshiab, du nto, thiab cov neeg kho tshuab siab, tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov casting ntawm qhov loj thiab nyias-walled; 4. Tshem tawm qhov kev xav tau ntawm feeder risers, thiab nce cov nqi siv hlau rau 90-98%; 5. Kev siv zog tsawg, kev ua haujlwm zoo, thiab cov cuab yeej siv yooj yim, yooj yim rau kev paub tshuab thiab automation. Daim ntawv thov: Feem ntau cov khoom siv (lub tog raj kheej taub hau, lub log hub, lub tog raj kheej ncej, thiab lwm yam).

(2) Centrifugal casting: Centrifugal casting yog ib txoj kev casting uas molten hlau yog poured rau hauv ib tug rotating pwm, thiab cov pwm yog sau nyob rau hauv qhov kev txiav txim ntawm centrifugal quab yuam kom solidify thiab zoo. Cov txheej txheem ntws: txheej txheem cov yam ntxwv thiab qhov zoo: 1. Yuav luag tsis muaj hlau noj nyob rau hauv cov txheej txheem pouring thiab riser system, uas txhim kho cov txheej txheem yield; 2. Cov tub ntxhais tuaj yeem raug tshem tawm thaum tsim cov hollow castings, yog li nws tuaj yeem txhim kho tau zoo thaum tsim cov tubular castings ntev. Txhim kho hlau filling peev xwm; 3. Cov khoom siv ntom ntom ntom ntom ntom ntom, tsawg dua qhov tsis xws luag xws li pores thiab slag suav, thiab cov khoom siv hluav taws xob; 4. Nws yog qhov yooj yim los tsim cov thoob thiab lub tes tsho sib xyaw hlau castings. Qhov tsis zoo: 1. Muaj qee qhov kev txwv thaum siv los tsim cov khoom tshwj xeeb zoo li cov castings; 2. Lub cheeb ntawm lub puab qhov ntawm lub casting yog tsis raug, lub puab qhov nto yog ntxhib, qhov zoo yog tsis zoo, thiab cov nyiaj txiag machining yog loj; 3. Lub casting yog yooj yim rau segregation ntawm lub ntiajteb txawj nqus. Daim ntawv thov: Centrifugal casting yog thawj zaug siv los tsim cov kav dej. Nyob rau hauv tsev thiab txawv teb chaws, centrifugal casting yog siv nyob rau hauv metallurgy, mining, tsheb thauj mus los, irrigation, ntws machinery, aviation, lub teb chaws tiv thaiv, tsheb, thiab lwm yam industries los tsim steel, hlau, thiab non-ferrous carbon alloy castings. Ntawm lawv, kev tsim cov castings xws li centrifugal cam khwb cia hlau kav, sab hauv combustion engine lub tog raj kheej liners, thiab lub tes tsho ncej yog feem ntau.
