Cov yam ntxwv smelting ntawm lub cub hluav taws xob yog ib qho kev xav txog ntawm cov khoom siv thiab cov txheej txheem smelting. Cov tsis muaj thiab cov ntsiab lus uas muaj kev cuam tshuam cov yam ntxwv melting ntawm lub cub hluav taws xob muaj xws li txoj kab uas hla ntawm cov tshuaj tiv thaiv cheeb tsam, qhov tob tob ntawm cov electrode, kev khiav hauj lwm tsis kam, lub tshav kub faib coefficient ntawm lub cub hluav taws xob, roj permeability ntawm tus nqi, thiab cov khoom siv hluav taws xob. tshuaj tiv thaiv ceev ntawm cov khoom siv raw.
Cov yam ntxwv melting ntawm hluav taws xob furnaces feem ntau hloov nrog cov kev hloov ntawm sab nraud xws li cov khoom siv raw thiab kev ua haujlwm. Ntawm lawv, qee cov yam ntxwv tsis zoo yog qhov tsis txaus ntseeg, thiab lawv cov txiaj ntsig feem ntau nyuaj rau ntsuas kom raug.
Tom qab kev ua kom zoo ntawm cov khoom siv raw khoom thiab kev ua haujlwm, cov yam ntxwv ntawm lub tshuab hluav taws xob muaj kev cuam tshuam txog qhov tsim nyog ntawm cov qauv tsim.
Cov yam ntxwv smelting ntawm slag smelting (silicon-manganese smelting) feem ntau suav nrog:
(1) Cov yam ntxwv ntawm lub pas dej molten nyob rau hauv cheeb tsam cov tshuaj tiv thaiv, lub zog faib cov yam ntxwv ntawm peb-theem electrodes, cov yam ntxwv ntawm cov electrode insertion qhov tob, lub cub tawg kub thiab lub zog ceev cov yam ntxwv.
(2) Qhov kub ntawm lub cub tawg yog cuam tshuam los ntawm ntau yam thaum lub sij hawm smelting txheej txheem. Kub hloov pauv cov tshuaj sib npaug ntawm cov hlau slags, ua
(3) Alloy muaj pes tsawg leeg hloov pauv. Qhov hloov pauv ntawm cov ntsiab lus hauv cov alloy qhia txog kev hloov pauv ntawm qhov cub kub rau qee qhov.
Piv txwv li: cov ntsiab lus ntawm txhuas nyob rau hauv ferrosilicon muaj feem xyuam rau lub cub tawg kub, qhov kub ntawm lub cub tawg ntau dua, qhov txo qis ntawm aluminium ntau dua.
(4) Nyob rau hauv tus txheej txheem ntawm pib lub cub tawg, cov ntsiab lus txhuas ntawm cov hlau yuav maj mam nce nrog qhov nce ntawm qhov cub kub, thiab cov ntsiab lus txhuas ntawm cov hlau kuj stabilizes thaum lub cub tawg kub stabilizes.
Qhov hloov pauv ntawm cov ntsiab lus silicon hauv manganese silicon alloy kuj tseem cuam tshuam qhov kev hloov ntawm qhov cub qhov rooj kub. Raws li lub melting point ntawm lub slag nce, lub superheat ntawm cov alloy nce, thiab cov ntsiab lus silicon nce raws li.
