Cov teeb meem cuam tshuam rau kev pabcuam lub neej ntawm cov cib ua hluav taws xob hauv cov roj cua

Hauv kev tsim khoom thiab ua haujlwm tiag, cov xwm txheej uas cuam tshuam rau kev pabcuam lub neej ntawm cov cib hluav taws xob rau cov cua sov ua kom sov tuaj yeem muab faib ua peb pawg: thermal kev ntxhov siab shear extrusion, tshauv yaj ntxhua thiab cov tshuaj tiv thaiv yaig.

1, thermal stress shear extrusion

Thaum pib, kaw thiab txheej txheem kom qhuav ntawm lub tshuab ua kom lub tshuab tso pa, vim qhov sib txawv ntawm qhov kub nce thiab txias txias ntawm cov cib ua hluav taws thaum lub cua sov lossis txheej txheem txias ntawm lub tshuab ua kom sov, kev sib txheeb txheeb ze tshwm sim. Cov cua sov nthuav dav ntawm cov cib hluav taws xob ua rau txiav thiab nyem ntawm nruab nrab cov nplaim hluav taws. Siab, ua rau cov nplaim tawg, cov nplaim hluav taws kub hnyiab thiab txawm tias ib nrab ntog saum npoo av. Cov kab nrib pleb no muab cov channel rau kev nkag mus ntawm cov hmoov tshauv molten.

2, molten tshauv yaig

Thaum lub sijhawm ua haujlwm ntawm lub tshuab ua kom lub tshuab ua pa, ntau qhov kub thiab txias tshauv thiab cov slag nqa los ntawm huab cua nrawm yuav ua rau muaj zog hnav thiab yaig ntawm cov nplaim hluav taws kub, ua rau maj mam hnav thiab ua kom tawv nqaij ntawm lub cib refractory.

3, tshuaj lom neeg cov tshuaj tiv thaiv corrosion

Thaum lub sijhawm ua haujlwm ntawm lub tshuab ua pa, cov kua silicon dioxide, txhuas oxide, titanium oxide, potassium oxide, sodium oxide thiab lwm yam tsis huv hauv qhov kub kub molten tshauv nkag mus rau qhov tob ntawm cov nplaim hluav taws los ntawm cov nplaim tawg thiab tawg ntawm cov nplaim hluav taws, thiab dhau los ntawm qhov hws ntawm cov cib hluav taws xob. Nkag mus rau sab hauv ntawm cov nplaim hluav taws. Cov tshuaj tiv thaiv tshuaj nruab nrab ntawm cov khoom siv hluav taws xob qis thiab cov khoom siv hluav taws xob ua kom tawg tau maj mam tsim, uas txo qis lub zog, tawv thiab tiv taus kub ntawm cov cib refractory.
