European iav kev lag luam siv ntau tshaj 100,000 tons ib xyoos ib zaug rau ntawm qhov cub nrog lub neej ntawm 5-8 xyoo, uas ua rau ntau txhiab tons ntawm cov khoom pov tseg refractory los ntawm kiln dismantling.Feem ntau ntawm cov ntaub ntawv no raug xa mus rau cov chaw pov tseg cov chaw pov tseg (CET) lossis cov chaw khaws khoom ntiag tug.
Txhawm rau txo cov ntaub ntawv pov tseg uas tau xa mus rau qhov chaw pov tseg, VGG tau koom tes nrog cov tuam txhab iav thiab kiln dismantling los tsim cov qauv kev lees paub pov tseg thiab tsim cov khoom tshiab tsim los ntawm cov khoom siv rov ua dua tshiab.Tam sim no, 30-35% ntawm cov khoom siv silica uas tau muab tshem tawm los ntawm qhov cub tuaj yeem rov qab siv dua los ua ob hom cib, suav nrogsilicawedge bricks siv rau cov pas dej ua hauj lwm los yog cov cua sov cia chamber ru tsev, thiab lub teeb yuag rwb thaiv tsevsilicacib.
Muaj lub Hoobkas nyob sab Europe uas tshwj xeeb hauv kev rov ua dua tshiab ntawm cov ntaub ntawv pov tseg refractory los ntawm iav, hlau, incinerators, thiab tshuaj lom neeg kev lag luam, ua tiav qhov rov qab ntawm 90%.Lub tuam txhab iav tau ua tiav cov txiaj ntsig zoo ntawm lub pas dej phab ntsa los ntawm kev txiav nws tag nrho tom qab qhov cub melting, tshem tawm cov iav adhering rau saum npoo ntawm ZAS cib siv, thiab ua rau cov cib tawg los ntawm quenching.Tom qab ntawd cov khoom tawg tau muab tso rau hauv av thiab sifted kom tau gravel thiab hmoov zoo ntawm ntau qhov ntau thiab tsawg, uas tau siv los tsim cov khoom siv hluav taws xob qis thiab cov khoom siv hlau.
Txoj kev loj hlob ruaj khov tau raug muab coj los siv rau hauv ntau qhov chaw ua ib txoj hauv kev los ua qhov tseem ceeb rau kev txhim kho kev lag luam mus sij hawm ntev uas xav txog ob qho tib si tam sim no thiab yav tom ntej tiam neeg xav tau thiab muaj peev xwm, tso lub hauv paus rau ecological civilization kev tsim kho.Kev lag luam graphite crucible tau tshawb nrhiav thiab tshawb nrhiav kev txhim kho kom ruaj khov rau ntau xyoo.Tom qab cov txheej txheem ntev thiab nyuaj, qhov kev lag luam no thaum kawg tau pib nrhiav kev cia siab rau kev txhim kho kom ruaj khov.Qee lub tuam txhab graphite crucible tau pib siv "carbon forestation," thaum lwm tus tab tom nrhiav cov khoom siv tshiab thiab cov txheej txheem tshiab los hloov cov graphite crucibles.
Qee lub tuam txhab txawm nqis peev ntau hauv thaj av hav zoov txawv teb chaws kom txo lawv txoj kev vam khom rau Tuam Tshoj cov peev txheej hav zoov.Niaj hnub no, peb xav tsis thoob los nrhiav kev txhim kho tshiab rau kev lag luam graphite crucible los ntawm txoj kev yuav khoom thiab rov siv cov qub graphite crucibles.Nyob rau hauv qhov kev ua siab loj siab qis-carbon ib puag ncig kev sib tw, kev lag luam graphite crucible tau rov ua qhov tseem ceeb thiab tus nqi tsim kho tshiab.
Peb ntseeg siab tias qhov no yuav yog txoj hauv kev tshiab hloov kho kom ruaj khov rau kev lag luam graphite crucible hauv Suav teb thiab nws tau nkag mus rau theem tshiab ntawm kev txhim kho tiam sis.Kev lag luam graphite crucible yog nyob ntawm cov peev txheej hav zoov, thiab vim tias cov peev txheej no dhau los ua tsawg zuj zus, tus nqi ntawm cov khoom siv raw siv hauv graphite crucibles nce.
Yuav ua li cas txo cov nqi tsim khoom ntawm graphite crucibles yam tsis muaj kev cuam tshuam lawv qhov zoo ib txwm ua rau mob taub hau rau cov tuam txhab.Raws li cov khoom siv ntuj tsim muaj rau kev lag luam poob qis, kom tswj tau lub neej zoo, leej twg tuav txoj kev loj hlob tam sim no ntawm kev lag luam ntsuab, cov cuab yeej siv hluav taws xob tsawg, thiab cov khoom siv hluav taws xob tsawg-carbon ib puag ncig tiv thaiv cov saw hlau yuav tuav txoj haujlwm tseem ceeb hauv kev lag luam. kev lag luam kev sib tw nyob rau hauv lub xyoo pua 21st.Nws yog qhov nyuaj los txo cov pa roj carbon dioxide emissions thaum lub sij hawm tag nrho cov txheej txheem ntawm graphite crucibles.
