Keeb kwm ntawm tuag casting.

Keeb kwm ntawm tuag casting.

Cov piv txwv ntxov tshaj plaws ntawm kev tuag casting los ntawm kev txhaj tshuaj siab - tsis zoo li casting los ntawm lub ntiajteb txawj nqus - tshwm sim nyob rau hauv nruab nrab-1800s. Ib daim ntawv pov thawj tau muab tsub rau Sturges hauv 1849 rau thawj lub tshuab ua haujlwm rau kev luam ntawv hom. Cov txheej txheem tau txwv rau lub tshuab luam ntawv hom rau 20 xyoo tom ntej, tab sis kev loj hlob ntawm lwm cov duab pib nce mus rau qhov kawg ntawm lub xyoo pua. Los ntawm 1892, cov ntawv thov kev lag luam suav nrog cov ntawv sau npe thiab cov ntawv sau nyiaj ntsuab, thiab kev tsim khoom loj ntawm ntau hom khoom pib thaum xyoo 1900s.

Thawj qhov tuag casting alloys yog ntau yam sib xyaw ntawm tin thiab txhuas, tab sis lawv cov kev siv tau poob qis nrog kev qhia txog zinc thiab aluminium alloys hauv xyoo 1914. Magnesium thiab tooj liab alloys sai sai ua raws li, thiab los ntawm xyoo 1930, ntau cov khoom siv niaj hnub no tseem siv niaj hnub no. muaj.

Cov txheej txheem tuag casting tau hloov zuj zus los ntawm thawj txoj kev txhaj tshuaj qis qis rau cov tswv yim suav nrog kev kub siab casting - ntawm cov rog tshaj 4500 phaus ib square inch - nyem casting thiab semi-solid tuag casting. Cov txheej txheem niaj hnub no muaj peev xwm ua kom muaj kev ncaj ncees, nyob ze ntawm lub ntsej muag zoo li cas nrog cov txheej txheem zoo heev.
