Kev piav qhia ntawm Kev Tsim Khoom Siv Rau Cov Khoom Siv iav

Nov yog cov lus piav qhia ntawm cov txheej txheem tsim khoom rau cov khoom iav:

Raw Material Preparation: Cov txheej txheem pib los ntawm kev sau cov ntaub ntawv raw uas xav tau los ua iav, uas feem ntau suav nrog silica xuab zeb, dej qab zib tshauv, limestone, thiab lwm yam khoom ntxiv. Cov ntaub ntawv no tau ua tib zoo ntsuas thiab sib xyaw hauv qhov xav tau proportions.

Melting: Cov khoom sib xyaw ua ke yog ces muab tso rau hauv lub cub tawg ntawm qhov kub thiab txias, feem ntau nyob ib ncig ntawm 1,500 degrees Celsius (2,732 degrees Fahrenheit). Qhov kub kub no melts cov ntaub ntawv raw, tsim ib lub iav molten.

Shaping: Thaum lub khob nyob rau hauv nws lub xeev molten, nws tuaj yeem ua rau ntau hom. Muaj ntau ntau txoj hauv kev rau shaping iav, suav nrog:

Tshuab: Nyob rau hauv txoj kev no, ib lub tshuab raj siv lub tshuab tshuab los sau cov iav molten los ntawm lub cub tawg thiab ua kom nws los ntawm tshuab cua rau hauv cov yeeb nkab, tsim cov cua siab uas nthuav cov iav mus rau hauv daim ntawv xav tau.

Nias: Rau qee yam khoom siv iav, molten iav yog nchuav rau hauv pwm ua ntej thiab nias rau hauv cov duab siv lub tshuab xovxwm. Cov txheej txheem no feem ntau yog siv rau kev tsim khoom loj.

Casting: Hauv iav casting, molten iav yog poured rau hauv pwm thiab sab laug kom txias thiab solidify lub sij hawm. Txoj kev no feem ntau yog siv los tsim cov khoom siv iav zoo nkauj lossis cov khoom zoo nkauj.

Annealing: Tom qab lub iav zoo li tus, nws nkag mus rau txheej txheem hu ua annealing. Annealing yuav maj mam txias lub khob hauv kev tswj hwm kom txo tau cov kev ntxhov siab sab hauv thiab ntxiv dag zog rau cov khoom. Qhov no pab tiv thaiv kev tawg lossis tawg tom qab.

Tiav: Thaum lub iav tau annealed thiab txias, nws dhau los ua ntau yam txheej txheem tiav. Cov no tuaj yeem suav nrog txiav, sib tsoo, polishing, thiab etching kom ua tiav cov duab xav tau, smoothness, thiab cov teebmeem zoo nkauj. Cov kev kho mob ntxiv, xws li siv cov txheej txheem los yog xim, kuj yuav ua tau nyob rau theem no.

Kev Tswjhwm Zoo: Thoob plaws hauv cov txheej txheem tsim khoom, kev tswj xyuas kev ua tau zoo yog siv los xyuas kom meej tias cov khoom iav ua tau raws li cov qauv xav tau. Qhov no suav nrog kev tshuaj xyuas lub khob rau qhov tsis xws luag, xws li npuas, tawg, lossis qhov chaw tsis sib xws, thiab tsis lees txais cov khoom tsis zoo.

Ntim thiab Kev faib tawm: Thaum kawg, cov khoom iav tiav tau ua tib zoo ntim los tiv thaiv lawv thaum thauj thiab khaws cia. Tom qab ntawd lawv muab faib rau cov muag khoom, cov khw muag khoom, lossis ncaj qha rau cov neeg siv khoom, npaj rau kev siv lossis muag.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov txheej txheem tsim khoom tshwj xeeb yuav txawv nyob ntawm seb hom iav khoom tsim, nrog rau cov yam ntxwv thiab cov kev xav tau.
