Nruam ntauwd melting rauv
Nws yog rhuab los ntawm cov roj ntuj thiab feem ntau yog siv rau kev sib tsoo Al. cov kab ke ci thiab cov nplai. Hom ntauwd tuaj yeem txuag tau cov nkev ntau dua 25%. Al. kua tawm nrog cov rho tawm ib hlis lossis tsis siv neeg, ob hom.
Nta
1. Cov qauv dav dav tau muab faib ua ob pawg: Japanese-style ntauwd rooj tog thiab European-style ntauwd rooj tog;
2. Kev siv ua kom zoo ntawm cov nplaim taws ua hluav taws xob muaj li 0.5T / h txog 3T / h, thiab chav tuav muaj peev xwm ntau los ntawm 1.5T txog 8T;
3. oxidation hlawv poob: Japanese cua sov ≤1.5% (tshiab txheem aluminium ingot), European cub tawg ≤1.0% (tshiab txheem txhuas ingot);
4. Qhov ntsuas kub tswj qhov tseeb ntawm cov roj ntsha ntawm txhuas yog ± 5 ℃, lub kaw lus ceev yog 10KPA, thiab lub siab ua ntej ntawm lub qhov ncauj yog 3-4KPA.
