Raws li qhov yooj yim ntawm kev lag luam niaj hnub, cov khoom siv tau siv hauv cov txheej txheem ua lag luam ua kom zoo dua qub, uas cuam tshuam nrog cov khoom lag luam ua lag luam kom zoo dua qub,
Kev tsim cov nrumtsum feem ntau pib nrog cov khoom siv pwm kom paub meej tias cov khoom lag luam cov khoom lag luam yog qhov tsim nyog rau cov khoom lag luam tshwj xeeb yog qhov tsim nyog rau cov hom cam khwb thiab ntau lawm Yuav tsum .}
Tom ntej no yog Smelting Stage . Cov ntaub ntawv hlau yuav tsum tau ua kom meej thaum muaj kuab lom thiab tshuaj lom neeg {} Cov tshuaj tshiab niaj hnub siv cov cuab yeej siv hluav taws xob smelting los txhim kho kev ua tau zoo thiab txo cov tib neeg ua yuam kev {4 4}}
Tom qab smelting, cov kua hlau tau hliv rau hauv cov pwm, thiab cov kev xav tau tshwj xeeb ntawm cov khoom siv casting, thiab cov khoom siv hluav taws xob tshwj xeeb puab .
After solidification, the casting needs to be cleaned and processed. Cleaning includes removing excess parts such as pouring risers, flash and burrs to ensure that the surface of the casting is clean. Subsequently, the casting may need to be heat treated, machined or surface treated to improve its strength, wear resistance or corrosion resistance.
Thaum kawg, tus casting yuav yauv mus kuaj qhov zoo, suav nrog kev ntsuas kev ntsuas thiab cov neeg siv khoom siv rau cov rooj sib txoos lossis siv.
Cov txheej txheem ntau lawm ntawm cov chaw ua haujlwm cuam tshuam nrog ntau qhov kev sib tham ua lag luam thiab txhawb nqa kev sib koom tes ua lag luam zoo dua qub, tsis yog muaj kev koom tes zoo ntawm kev koom tes.
