Covslag ibyog lub thawv ntim khoom thiab kev kho mob tsim los rau kev kho cov slag pov tseg, txhim kho kev ua haujlwm zoo thaum muab kev lees paub rau kev nyab xeeb thiab ib puag ncig. Huantai tseem tuaj yeem muab rau koj nrog ntau qhov sib txawv ntawm qhov sib txawv ntawm slag hauv, dross yias, tseb pwm thiab lwm yam khoom siv smelting, kuj tuaj yeem kho raws li koj qhov kev xav tau ntau lawm, kom ntseeg tau tias kev sib koom ua ke nrog koj cov txheej txheem ntau lawm.
► Yuav ua li cas molten slag thauj los ntawm lub cub tawg?
Muaj ob txoj hauv kev tseem ceeb los hloov cov kua dej kub los ntawm smelting furnaces:
Slag Pot Hloov: Molten slag yog ladled los ntawm ib tug crane mus rau hauv loj reinforced slag pots. Thaum ua tiav, cov lauj kaub hauv qab yog coj mus rau qhov chaw ua haujlwm slag. Molten slag tej zaum yuav granulated los yog solidified ua ntej thauj mus los txo nws cov kub thiab ua kom muaj kev ruaj ntseg. Qhov no tuaj yeem ua tiav los ntawm kev txau cov dej los yog lwm cov khoom ua kom txias rau hauv cov molten slag, tsim cov granules lossis pellets uas yooj yim rau kev tswj thiab thauj.
Slag Rail Tsheb: Ladles sau tshwj xeeb rail tsheb lined nrog refractory cib. Locomotives thauj cov tsheb thauj khoom mus rau qhov chaw slag. Qhov twg cov slag ntws nyob rau hauv lub ntiajteb txawj nqus los yog pumped mus rau ib tug cais ua los yog pov tseg chaw. Txoj kev no feem ntau yog siv rau hauv cov txheej txheem nruam nruam lossis cov nroj tsuag sib xyaw ua ke uas cov slag tau ua tsis tu ncua.
Molten slag tuaj yeem ncav cuag qhov kub txog li 3000 degree F (1650 degree), yog li hloov cov hlab ntsha yuav tsum tiv taus cua sov. Kev hloov pauv yooj yim yog qhov tseem ceeb kom tsis txhob muaj kev sib tsoo thiab kev sib tsoo nyob ib puag ncig cov khoom molten txaus ntshai.
Robust slag pots thiab tsheb ciav hlau yog tsim los kom muaj kev nyab xeeb muaj ntau txhiab phaus ntawm cov kua liab-kub slag thaum thauj. Kev thauj mus los ntawm molten slag yog ib feem tseem ceeb ntawm cov txheej txheem metallurgical, thiab ua tib zoo xav txog yuav tsum tau muab rau kev nyab xeeb, kev ua tau zoo, thiab kev cuam tshuam ib puag ncig thaum xaiv txoj kev thauj mus los uas tsim nyog.
► Qhov twg slag coj mus rau txias thiab ua?
Tom qab tawm hauv qhov cub, slag yuav tsum txias thiab khov ua ntej tuav ntxiv. Nws raug coj mus rau lub slag processing yard.
◇ Dedicated slag pits muab thaj chaw tswj kev pov tseg thiab txias slag.
◇ Thaum txias, cov khoom loj tuaj yeem tawg thiab ua tiav raws li xav tau.
◇ Tej zaum yuav muaj kev sib tsoo, kev tshuaj ntsuam xyuas, cov hlau nplaum, qhov loj me, thiab kev faib tawm.
◇ Residual metallic cov ntsiab lus tuaj yeem rov qab los ntawm cov khoom siv slag.
◇ Muab cov khoom lag luam muag muag muag thiab npaj cov khoom seem hlau.
Qhov kev qhia dav dav no ua rau cov khoom lag luam muag khoom lag luam thiab npaj cov khoom seem hlau, ua rau tag nrho cov txheej txheem nqi-zoo thiab ib puag ncig zoo. Ua tib zoo ua kom txias thiab ua haujlwm hloov molten slag rau hauv cov ntaub ntawv ruaj khov rau rov siv dua. Los ntawm ua tib zoo ua kom txias thiab ua cov molten slag, nws tau hloov mus rau hauv cov ntaub ntawv ruaj khov uas tsim nyog rau kev rov qab siv ntau yam kev siv, ua rau muaj txiaj ntsig zoo thiab txo qis hauv kev lag luam.
► Lub slag bin ua lub luag haujlwm tseem ceeb li cas?
CovSlag hauvmuab cov khoom ntim loj ntawm lub qhov cub thiab lub processor.
Covslag ibyog ib qho tseem ceeb ntawm kev ua cov molten slag los ntawm furnaces. Cov khoom siv dag zog no nrog cov ntaub ntawv refractory tuaj yeem tiv taus qhov kub thiab txias ntawm molten slag thiab muab cov khoom ntim loj ntawm lub qhov cub thiab cov khoom siv. Raws li cov khoom siv slag los yog lub tsheb tuaj txog, lawv tso lawv cov ntsiab lus mus rau hauv cov khoom, qhov twg cov slag tuav kom txog thaum nws npaj txhij rau kev ua haujlwm ntxiv. Nrog rau qhov muaj peev xwm ntawm 20 tons lossis ntau dua, cov bins no yog tsim los nrog cov qhov rooj qhib hauv qab uas tso cai rau kev tswj cov dej. Cov bins yog elevated ntawm cov pob zeb hauv paus ntawm qhov siab uas yooj yim rau cov slag pots, thiab lawv tau teem rau hauv lub vaj slag raws li cov khoom siv ua haujlwm.
Raws li ib qho tseem ceeb buffer, lubslag ibenables du ua hauj lwm ntawm lub cub tawg thiab processors. Lub peev xwm khaws cia thiab tswj cov dej ntws ntawm slag tso cai rau cov txheej txheem ntau lawm, txo qis sijhawm thiab txhim kho kev ua haujlwm tag nrho. Yog li ntawd, cov khoom lag luam yog ib qho tseem ceeb ntawm cov khoom siv niaj hnub steelmaking, ua kom lawv ua tau raws li qhov xav tau ntawm kev lag luam hloov zuj zus. Lawv lub xub ntiag yog qhov tseem ceeb hauv cov khoom siv hlau niaj hnub no, uas lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li qhov xav tau ntawm kev lag luam.
► Dab tsi ntawm slag tau rov ua dua rau lwm daim ntawv thov?
Ua tsaug rau kev ua cov slag, cov seem slag zoo tuaj yeem nrhiav kev siv thib ob:
Cua txias slag: Crushed khoom siv los ua aggregates hauv pob zeb, asphalt, thiab lwm yam.
Granulated slag: Cov iav pellets siv los ua cov cement ntxiv, thiab sandblasting abrasive.
Pelletized slag: Tsim los rau hauv lub teeb yuag aggregate.
Hlau granules: Hlau thiab lwm yam hlau oxides yog reclaimed.
Lwm cov khoom siv slagnrhiav siv raws li kev tsheb ciav hlau ballast, vov tsev granules, av hloov kho, thiab lwm yam.
Ua tsaug rau kev ua slag, ntau hom slag tuaj yeem siv rau ntau yam kev siv. Cov ntaub ntawv sib txawv ntawm slag uas feem ntau rov siv dua muaj xws li cua txias slag, uas yog crushed thiab siv los ua aggregates hauv pob zeb thiab asphalt; granulated slag, uas yog hloov mus rau hauv iav pellets siv los ua cov cement ntxiv thiab sandblasting abrasive; pelletized slag, uas yog zoo li lub teeb aggregate; metallic granules, qhov twg hlau thiab lwm yam hlau oxides reclaimed; thiab lwm yam slag khoom uas yog siv raws li kev tsheb ciav hlau ballast, ru tsev granules, av kho, thiab lwm yam. Los ntawm kev siv aslag ib, kev siv tau zoo ntawm cov slag byproducts yog yooj yim, tiv thaiv lawv los ntawm kev mus pov tseg. Peb cov slag bins tau ua tib zoo tsim thiab tsim, Huantai yuav yog qhov kev xaiv zoo rau koj, tiv tauj peb ntawm tech@huan-tai.org.
