煅燒

Soda ash was obtained by calcining sodium bicarbonate. 重堿經(jīng)煅燒得純堿，母液經(jīng)蒸發(fā)得硫酸銨。

The relation beside the temperature of the product calcined and the final calcining temperature in production of prebaked-anode has been discussed. 并進(jìn)一步討論了預(yù)焙陽極生產(chǎn)工藝中，制品焙燒溫度與石油焦煅燒最終溫度的關(guān)系。
