Limestone kuj yog siv los tshem tawm cov impurities ntawm lub qhov cub tawg thaum ua hlau. Cov impurities feem ntau yog silicon dioxide (tseem hu ua xuab zeb). Calcium carbonate nyob rau hauv limestone reacts nrog silicon dioxide tsim calcium silicate (tseem hu ua slag).
txheej txheem dab tsi tshwm sim rau cov limestone ntxiv rau qhov cub tawg?
Limestone ntxiv rau hauv qhov cub tawg decomposes muab CaO uas ua rau slag hauv lub xeev molten thiab cais tawm ntawm hlau.
Dab tsi ntxiv rau lub qhov cub tawg?
tawg rauv, lub qhov cub ntsug ntsug uas tsim cov hlau ua kua los ntawm cov tshuaj tiv thaiv ntawm cov cua ntws los ntawm kev nkag siab hauv qab ntawm lub qhov cub nrog sib xyaw ntawm cov hlau ore, coke, thiab flux pub. mus rau sab saum toj.
Vim li cas limestone ntxiv rau qhov cub tawg hauv kev rho tawm cov hlau los ntawm haematite?
Limestone tshem tawm cov impurities uas muaj nyob hauv cov hlau ore. Qhov no ua tiav vim tias, thaum kub kub, calcium carbonate yuav raug thermal decomposition rau calcium oxide. Cov calcium oxide ces reacts nrog cov acidic impurities (tsuas yog silica) tam sim no nyob rau hauv cov hlau ore los ua molten slag (calcium silicate).
Yuav ua li cas rau limestone nyob rau hauv cub tawg?
Thib Ob - limestone decomposes hauv tshav kub los tsim calcium oxide (quicklime) thiab carbon dioxide. Lub limestone undergoes thermaldecomposition. Qhov thib peb - cov pa roj carbon dioxide reacts nrog ntau cov pa roj carbon monoxide tsim carbon monoxide.

Vim li cas tawg hauv qhov cub?
Yog li, Vim Li Cas Qhov Cub iav tawg lossis tawg? Tej zaum nws yuav tshwm sim tias koj lub qhov cub iav qhov rooj yog tawg ua ntu zus, tab sis nws feem ntau yog qhov tshwm sim ntawm ntau cov micro-cracks tsim lub sijhawm. Feem ntau ntawm cov qhov cub niaj hnub no siv cov iav tempered.
Kuv puas tuaj yeem siv qhov cub ntxuav ntawm qhov cub pyrolytic?
Tsis txhob siv cov khoom siv hluav taws xob ua lag luam hauv lossis ib puag ncig ntawm qhov cub huv tus kheej. Kev siv cov tshuaj ntxuav tes tas li ntawm lub qhov cub ntxuav tus kheej yuav ua rau etching thiab discoloration ntawm liner, thiab nws thiaj li ua rau lub qhov cub tsis huv thaum siv lub voj voog ntawm tus kheej.
Qhov cub qhov cub txheem yog dab tsi?
Tus qauv loj ntawm qhov cub yog nyob qhov twg ntawm 2 - 3 ko taw dav, 24 - 29 ntiv tes siab, thiab ib txwm hais txog 16 ntiv tob. Tau kawg, qhov qhib tuaj yeem sib txawv nyob ntawm koj qhov style thiab cov tswv yim tsim, nrog rau qhov chaw koj tab tom nrhiav qhov cub.
Leej twg detering nyob rau hauv tag nrho cov nyob ntsiag to nyob rau sab hnub poob pem hauv ntej?
Detering yog tus neeg ua liaj ua teb los ntawm Txhua Tus Neeg Tsis Txaus Siabntawm Sab Hnub Poob los ntawm Erich Maria Remarque. Nws muaj siab mos siab muag, tshwj xeeb tshaj yog thaum nws los txog rau nees. Nws muaj kev kub ntxhov loj heev thaum nws hnov cov nees quaj thiab txawm sim tua lawv kom kawg lawv txoj kev txom nyem.
