Lub tshuab nruam nruam, tseem hu ua lub tshuab nruam nruam, yog cov khoom siv tseem ceeb uas ncaj qha hloov cov hlau molten rau hauv cov khoom lossis ib nrab - cov khoom siv hluav taws xob los ntawm cov txheej txheem nruam nruam. Nws lub hauv paus ntsiab lus tseem ceeb nyob rau hauv kev ua tiav cov txheej txheem txuas ntxiv los ntawm cov kua mus rau cov khoom los ntawm crystallizer txias, thib ob txias txias, thiab cov txheej txheem casting, hloov cov kev sib txuam ntau lawm ntawm ntau lub ncuav thiab demolding hauv tsoos ingot casting.
Cov Ntsiab Cai thiab Cov Ntsiab Lus Tseem Ceeb Lub tshuab ua haujlwm tas li tuaj yeem muab faib ua peb kauj ruam:
Kev txhaj tshuaj ua kua:*High-kub molten hlau (xws li molten steel lossis aluminium) yog txhaj rau hauv lub crystallizer los ntawm tundish. Lub phab ntsa sab hauv ntawm lub crystallizer yog ua los ntawm dej- cov phaj tooj liab txias, thiab yuam kom txias ua rau lub plhaub tseem ceeb ntawm cov hlau.
Nruam Solidification thiab Casting: Lub plhaub pob zeb maj mam thickens nyob rau hauv lub crystallizer, thaum lub tshuab casting rub lub solidified billet downwards ntawm qhov ceev ceev (xws li, 0.5-2 m / min). Qhov thib ob qhov chaw txias txias ntxiv kom txias rau lub billet los ntawm cov tshuaj tsuag dej los yog huab cua huab cua kom ua tiav cov khoom tiav.
Txiav thiab tso zis: Tom qab solidification, lub billet yog nplaim taws - txiav los yog hydraulically sheared rau hauv ntev ntev (xws li, 6-25m) thiab xa ncaj qha mus rau lub dov txheej txheem los yog stacking.
Raws li cov duab billet, nruam casting tshuab tuaj yeem muab faib ua square billet nruam casting tshuab, round billet nruam casting tshuab, slab nruam casting tshuab, thiab irregularly zoo li billet nruam casting tshuab. Piv txwv li, round billet nruam casting tshuab (xws li lub tshuab nqus tsev nruam nruam casting hais nyob rau hauv cov ntaub ntawv cov khoom) yog tsim tshwj xeeb rau kev tsim cov hlau billets nrog ncig cross-sections. Lawv tsim nyog rau kev ua cov hlau ntshiab, siab - kub alloys, thiab tshwj xeeb alloys. Lawv qhov nrawm nrawm tuaj yeem ncav cuag 50mm / min, nrog qhov kub siab tshaj plaws ntawm 1600 degree. Ua ke nrog kev tiv thaiv argon / nitrogen thiab cov dej txias, lawv tuaj yeem ua kom muaj kev sib haum xeeb ntawm cov hlau alloy.
