Yuav tsum tau kho thiab ntxiv dag zog rau ob-alloy ntsia hlau
Nov 03, 2021
Cov cuab yeej txhaj tshuaj ntawm cov ntsia hlau txhaj tshuaj molding tshuab muaj lub thoob, ntsia hlau ntawm kev txhaj tshuaj molding tshuab, nozzle, Hopper, metering khoom, ntsia hlau kis tau tus mob, txhaj tshuaj chim, txhaj tshuaj txav chim thiab lwm yam khoom.
Kev ua haujlwm zoo ntawm ob chav alloy ntsia hlau muaj qhov tseem ceeb ntawm cov khoom siv plasticization, cov khoom zoo thiab kev ua haujlwm ntau lawm. Cov kev ua haujlwm zoo no muaj feem xyuam nrog kev tsim khoom precision thiab sib dhos clearance. Thaum cov khoom siv tiag tiag thiab cov zis ntawm extruder txo qis, qhov tsim nyog kho thiab ntxiv dag zog txoj hauv kev yuav tsum tau siv rau cov ntsia hlau ntxaib alloy.
1. Kev npaj ntawm qhov tsos
Ua ntej txau cov ntsia hlau vuam, cov khoom seem ntawm cov yas seem ntawm cov ntsia hlau yuav tsum tau muab cais tawm thiab ntxuav. Txoj kev ua tiav yog txhawm rau nruab cov ntsia hlau rau ntawm lub tshuab txau thiab tig nws, ci nrog cov nplaim nruab nrab ntawm rab phom txau, thiab tshem tawm nrog lub tshuab txiav tom qab yas. Tom qab ntawd, siv cov xuab zeb-blasting phom kom tiav qhov tsos thiab tshem tawm cov oxide txheej ntxiv.
2. Preheat
Thaum preheating, siv lub tshuab txheej los yog kev vibration vuam tshuab kom clamp lub taub hau ntsia hlau. Ua kom qhov kev sib hloov ceev ntawm lub tshuab cuab yeej qis dua 15r / nin, nruab nrab nplaim taws, preheat tag nrho cov ntsia hlau los ntawm muzzle rau cov ntsia hlau 100 hli mus txog 270, txo cov thermal stress ntawm lub ncej thiab xyuas kom zoo ntawm thermal txau txheej.
3. Dav hlau vuam
Tib lub tshuab vuam tshuab, xaiv SPH-1 / h tshuaj tsuag phom, No. 2 nozzle, oxygen siab 0.25MPa, acetylene siab 0.06MPa.
Thaum lub sij hawm kev sib hloov, cov ntsia hlau hnav ib feem raug kho los ntawm kev txau cov vuam, thiab cov ntsia hlau hnav yog li 2-3 hli. Hauv ib qho kev ua haujlwm, qhov loj txaus yuav tsum tau txau, thiab qhov chaw ua haujlwm yuav tsum tau txiav txim siab. Yog tias cov tshuaj tsuag tsis ua haujlwm ib zaug, xyuam xim rau qhov kub thiab txias preheating uniformity thaum rov welding lwm zaus los tiv thaiv cov txheej vuam los ntawm kev tawg.
4. Trimming thiab kho
Vim yog cov kev xav tau ntawm cov ntsia hlau ntsia hlau, uas yog qhov ncaj, qhov pom ntawm cov ntsia hlau thiab kev co ntawm cov ntsia hlau ua haujlwm ntawm cov ntsia hlau ncej kab, cov ntsia hlau yuav tsum tau txiav tom qab vuam. Txoj kev trimming yog ua cov mandrel ntawm qhov chaw nruab nrab thiab nias nws mus rau hauv qhov bearing qhov ntawm lub taub hau ntsia hlau.
5. Preheating ntawm lub workpiece ua ntej tha xim
Preheating lub workpiece ua ntej txheej muaj qhov ua tau zoo, uas tuaj yeem tshem tawm cov tsos ntawm noo noo thiab txo qhov kev ntxhov siab ntawm cov txheej, tshwj xeeb tshaj yog cov oxide nplai ncej zoo li peb lub Hoobkas, qhov kub thiab txias yog qhov tsim nyog ntawm txog 100C. Sab nraum cov ntawv kho mob, txhuas coated npib tsib xee sib xyaw hmoov F505 yog txau ua cov nplaum txheej. Lub thickness ntawm cov txheej txheem yuav yog 0.10-0.15. Txij li cov txheej no tsuas yog siv los ua kev sib xyaw ua ke, nws tsis tuaj yeem txau cov tuab heev.
Tom qab txau cov txheej khi, tshuaj tsuag G101 hmoov txheej ua haujlwm. G101 hmoov yuav tsum tau preheated ntawm qhov kub ntawm 105-250 ua ntej daim ntawv thov, thiab raug rho tawm haujlwm los xyuas kom meej lub flowability ntawm cov hmoov thiab tiv thaiv cov blocks los ntawm thaiv cov tshuaj tsuag channel. nruj me ntsis tswj lub siab ntawm ejected nruab nrab thiab roj, nplaim taws kub, ejected lub sij hawm, ejected lub kaum sab xis thiab txav ceev kom lub txheej txawm thiab tiaj tus, thiab lub tsev yog ruaj khov. Lub preheating kub yog 100-200C degrees Celsius. Txau nrug 180-200mm; Txau lub kaum sab xis 90; Txhaj phom txav ceev 12mm / min; Roller linear ceev yog 8-12m / min.
Yog tias cov nplaim nruab nrab siv thaum txau cov txheej txheem ua haujlwm, cov hmoov tuaj yeem pom los ntawm cov nplaim taws, thiab cov hmoov ntawm qhov kawg ntawm cov nplaim taws yog dawb. Qhov no txhais tau hais tias yog qhov kub thiab txias, qhov kub yuav tsis ua haujlwm yog tias nws yog xim liab lossis xim liab. Nyob rau lub sijhawm no, nws yog qhov zoo dua los kho qhov loj ntawm cov hmoov pub airflow thiab cov nplaim hluav taws xob kom sov cov hmoov ua dawb. Tam sim no cov hmoov muaj qhov kub thiab txias, ceev ceev thiab zoo tsub zuj zuj nyhuv.
6. Hlau ua tom qab txheej
Tom qab tha xim tiav lawm, txheej txheej yog qhwv nrog asbestos hauv ntau txheej kom txias kom tsis txhob tawg. Tom qab txias rau chav tsev kub, lub tsheb ntxhib yog nqa tawm, thiab cov nyiaj sib tsoo tuaj yeem tso rau kev sib tsoo. Qhov yuav tsum tau teev thiab teev roughness ntawm kev sib tsoo drawings. Lub luag haujlwm hloov kho xaus ntawm no.
