Smelting yog muab ingots rau kev ua yas. Smelting furnaces feem ntau siv cov roj hluav taws xob reverberatory furnaces los yog roj hluav taws xob reverberatory furnaces, muaj peev xwm ntawm 20 mus rau 40 tons lossis ntau dua; kuj siv cov cua sov reverberatory furnaces, muaj peev xwm ntawm feem ntau txog 10 tons. Txhawm rau kom txo lub sijhawm ua haujlwm ntawm lub cub tawg, txhim kho kev ua haujlwm ntawm melting efficiency, thiab txo cov pa nqus thiab oxide zaj duab xis kev koom tes, tilting sab saum toj-loading ncig furnaces tau saws nyob rau hauv kev lag luam.
Nws yog qhov zoo tshaj plaws los siv cov cuab yeej tshuaj ntsuam xyuas sai los soj ntsuam cov alloy muaj pes tsawg leeg thaum lub sij hawm smelting thiab ua kom raws sijhawm. Txhawm rau kom ntseeg tau tias purity ntawm yaj, tiv thaiv cov pa phem ntawm cov pa phem thiab tswj cov tshuaj muaj pes tsawg leeg, ntxiv rau kom txo lub sijhawm smelting kom ntau li ntau tau, nws raug nquahu kom npog nws nrog cov hmoov flux feem ntau ntawm cov poov tshuaj chloride thiab sodium. tshuaj chloride. Qhov ntau npaum li cas yog {{0}}.4 mus rau 0.4% ntawm qhov hnyav ntawm tus nqi. 2%. Lub melting kub feem ntau yog tswj ntawm 700 ~ 750 degree.
