Kev sib piv ntawm Castings Thiab Stainless Hlau Forgings

Peb tsis yog tus neeg tsis paub zoo nrog kev nrum , thiab kev thov casting muaj keeb kwm ntev. Hauv cov khoom thaum ub, tib neeg siv cov neeg ua yeeb yam los ua nyiaj npib, riam phom, cuab yeej thiab qee yam khoom siv hauv tsev. Txawm li cas los xij, nyob rau lub sijhawm niaj hnub no, cov hlau nruas feem ntau yog siv los ua cov ntxhib ntawm cov tshuab seem lossis ncaj qha raws li tshuab qhov chaw. Qhov feem ntawm cov neeg tuaj yeem hauv cov khoom siv tshuab pib tau nce ntxiv, cov nyiaj ntawm cov kev siv kuj tseem nce xyoo los ntawm xyoo, thiab cov duab thiab ntau yam ntawm kev ua suab kuj tseem hloov tas li. Castings maj mam dhau los ua qhov tseem ceeb ntawm peb lub neej txhua hnub. Kev siv ntawm cov neeg tuaj yeem tuaj yeem pom nyob rau ntau qhov chaw xws li ntau lub qhov rooj tuav, lub qhov rooj xauv, thiab lub qhov dej me.

Lub casting muaj cov khoom siv zoo thiab lub cev zoo nkauj heev. Nws tuaj yeem muaj ntau yam khoom ntawm lub zog, tawv thiab tawv. Nws kuj tseem tuaj yeem muaj ib lossis ntau yam khoom tshwj xeeb, xws li hnav tsis kam, siab kub thiab tsis kub tsis kam, tiv thaiv corrosion, thiab lwm yam.

Lub suab seev muaj ntau qhov nyhav thiab qhov ntau thiab tsawg. Qhov hnyav tshaj tsuas yog ob peb grams, hnyav tshaj plaws tuaj yeem ncav cuag 400 tons, qhov hnyav tshaj plaws ntawm phab ntsa tuab tsuas yog 0.5 hli, thiab tuab tau tshaj li 1 meter. Muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm kev lag luam sib txawv.

Sib piv qhov sib txawv ntawm kev ua si thiab cov hlau cuav:

1. Castings muaj zoo abrasion tsis kam thiab poob siab nqus, vim graphite hauv cam khwb cia hlau yog qhov zoo rau lubrication thiab roj cia, yog li nws muaj zoo abrasion tsis kam. Ib yam li ntawd, grey graphite cam khwb cia hlau tau zoo dua qhov kev poob siab dua li cov hlau vim muaj graphite.

2. Lub casting muaj cov txheej txheem zoo. Vim tias cov pa roj carbon ntau ntawm cov xim grey cam khwb cia hlau, uas yog ze rau eutectic muaj pes tsawg leeg, lub ntsiab lus melting yog qhov tsawg, cov npliag npliag zoo, thiab qhov shrinkage tsawg. Yog li ntawd, nws tsim nyog rau nrum nrog cov nruas tawv lossis nyias-walled. Nws yog qhov yooj yim los ua cov nti tawg thaum lub sijhawm txiav, yog li ntawd qhov ua kom lub tshuab ntawm grey cam khwb cia hlau zoo dua li ntawm cov hlau.

3. Tom qab forging, stainless hlau tuaj yeem txhim kho nws cov microstructure thiab cov yam ntxwv ua khoom. Vim muaj kev hloov pauv thiab kev rov ua dua tshiab ntawm stainless hlau tom qab kub ua haujlwm deformation ntawm txoj kev forging, thawj coarse dendrites thiab columnar nplej los ua equiaxed recrystallized cov qauv nrog cov finer nplej thiab teeb tsa qhov loj me, uas ua rau tus thawj cais, qhov kev cog lus thiab vuam ntawm looseness, pores , thiab slag suav ua cov qauv tsim ua kev sib txuam ntau dua, uas txhim kho cov khoom yas thiab cov khoom siv ntawm cov hlau.

4. Cov yam ntxwv ntawm cov khoom siv ntawm cov nrum yog qis dua li ntawm cov kev zam ntawm cov khoom qub. Txawm li cas los xij, cov txheej txheem forging tuaj yeem ua kom txuas ntxiv ntawm cov hlau fiber qauv, ua cov qauv fiber ntau ntawm lub forging ua tau zoo nrog cov duab ntawm lub forging, thiab xyuas kom lub qhov muaj cov tshuab zoo thiab lub neej ntev kev pab. Precision tuag forging, txias extrusion, sov extrusion thiab lwm cov txheej txheem yog siv. Cov ntawv zam tsim tawm yog cov tsis tau ua los ntawm kev cia.

Ob qho tib si cuam thiab hlau txhuam kev zam txim yog qhov tsis tuaj yeem hauv cov khoom siv tshuab. Hauv kev tsim tshuab, raws li cov khoom sib txawv ntawm cov khoom lag luam, xaiv qhov sib thooj los yog kev zam txim. Tsuas yog los ntawm kev siv tag nrho lub luag haujlwm ntawm kev ua los yog kev zam txim tuaj yeem muaj cov khoom siv zoo nkauj.
