Izidingo ezintathu zokuncibilika ngaphakathi ukuchithwa kwesithando somlilo

1. Isamba esiphelele se-slag ngokwethiyori sibeka ukuthi u-1.5-2% we-2-3% yesithando somlilo sokuncibilika kufanele uqinisekiswe, okungukuthi, u-25-30 kg womcako ubalulekile, 5-8 kg we-fluorite, 1.2-1.5 kg we-lime i-ejenti yokunciphisa/isithando somlilo, hlola eyodwa Hlola inani lomcako ngosuku kanye nenani lenyanga le-Ca-Si powder, futhi uyazi ukuthi ikude ukuhlangabezana nezidingo.

2. Ushintsho lwe-slag alukho ngaphansi kwezikhathi ezingu-2.5-3, futhi i-slag ye-oxidation ithathelwa indawo nge-slag entsha; iningi lamasampula e-pre-deoxidation slag ashintshwa nge-slag entsha; i-alloy yengezwe ukupholisa insimbi esikhundleni se-slag entsha. Lezi zikhathi ezintathu kufanele zingenzeki.

3. Ukufakwa kwe-aluminium yokugcina ye-deoxidation ye-H13 0.8-1.0 kg / ton, qinisekisa ukuthi induku ye-electrode inokuqukethwe kwe-aluminium ≥0.004%, ungafaki i-aluminium powder ku-ladle ukuze ubeke esikhundleni sokufakwa kwe-aluminium ye-deoxidation yokugcina; uma i-chromium emaphakathi incibilika, insimbi ephezulu ye-chromium abrasive izoncibilika ensimbi I-oksijeni iphansi. Uma inqubo yokuncibilikisa ingalungile ngokwanele ukwengeza i-aluminium, ngeke yengezwe.
