Kev Taw Qhia thiab Hom Submerged Arc Rauv
Submerged arc rauv yog tsuas yog siv los txo thiab smelting ore, lub ntsiab ntau yam ntawm smelting yog ferrosilicon, industrial silicon, silicon calcium alloy, siab carbon ferromanganese, manganese silicon alloy, siab carbon ferrochrome, silicon chromium alloy, silicon aluminium alloy thiab tsawg lub ntiaj teb alloy. , thiab lwm yam, ntxiv rau smelting npua hlau, calcium carbide, daj phosphorus, nickel matte thiab corundum thiab lwm yam khoom.
Lub cub tawg feem ntau yog siv cov khoom siv carbonized los yog magnesia-based refractory li hauv ob sab phlu, siv tus kheej-baking electrodes, thiab ntxig electrodes rau hauv tus nqi los siv submerged arc ua haujlwm, ua tiav kev pub noj, sib tshuam tapping thiab slagging, thiab ua haujlwm tas mus li. Lub tshav kub ntawm lub submerged arc rauv feem ntau yog los ntawm Joule tshav kub ntawm cov yaj tsis kam, thiab lub arc tshav kub yog tsawg los yog tsis muaj arc.
Raws li cov yam ntxwv ntawm cov khoom siv, lub cub tawg tuaj yeem muab faib ua:
- Ib-theem, ib leeg-electrode hluav taws xob rauv thiab peb-theem peb-electrode hluav taws xob rauv;
- Qhib hom hluav taws xob rauv, semi-enclosed hluav taws xob rauv thiab tag nrho cov hluav taws xob rauv;
- Tsau thiab teb hluav taws xob rauv;
- Circular reduction furnace thiab rectangular furnace, etc.
Qhov qhib hom submerged arc furnace muaj cov qauv yooj yim, kev nqis peev me me thiab kev saib xyuas yooj yim, tab sis kev ua haujlwm tsis zoo, uas tsis zoo rau kev tshem tawm cov pa luam yeeb thiab plua plav, thiab ua rau ib puag ncig zoo. Lub semi-enclosed submerged arc rauv muaj kev siv zog tsawg thiab tuaj yeem rov qab tau cov hluav taws xob rau hluav taws xob, tab sis cov qauv ntawm lub tshuab hluav taws xob yog qhov nyuaj, nyuaj rau kev khiav lag luam thiab tswj, tshwj xeeb tshaj yog rau cov khoom siv raw ntawm lub cub tawg yog nruj, thiab kev tsim kho. tus nqi siab. Rau qee hom me me submerged arc ntxhia rauv, nws tsis tuaj yeem ua haujlwm kaw thaum lub sij hawm smelting, thiaj li yuav txo tau tus nqi ntawm purification kho roj, tiv thaiv ib puag ncig, thiab rov qab cov khib nyiab cua sov nyob rau hauv lub cub tawg, nce los yog hloov mus rau hauv. ib tug semi-kaw submerged arc rauv. Lub siab fume hood qhib hom submerged arc furnaces feem ntau yog siv nyob rau hauv peb lub teb chaws rau cov laj thawj xws li lub peev xwm me me thiab cov cuab yeej siv qis. Tam sim no cov tshiab tsim thiab kev kho dua tshiab submerged arc furnaces yuav tsum tau txais cov fume hood semi-enclosed hom lossis tag nrho-kaw hom.
