Hais txog Kev Xaiv Cov Khoom Zoo Raw Ore

 

Ore Qib Kev Ntsuas:
Ua ntej, yuav tsum tau ua qhov kev ntsuam xyuas qib siab ntawm cov hlau ore. Qhov no suav nrog kev txiav txim siab cov ntsiab lus hlau hauv cov ore nrog rau cov ntsiab lus tsis zoo xws li sulfur thiab phosphorus los ntawm kev tshuaj xyuas tshuaj. Dhau li ntawm qhov yuav tsum tau hais yav dhau los hais tias cov ntsiab lus hlau yuav tsum zoo dua siab dua 60%, rau cov ntsiab lus sulfur, cov hlau zoo yuav tsum tau tswj xyuas hauv qab no 0.05%, thiab cov ntsiab lus phosphorus zoo dua. qis dua 0.1%. Piv txwv li, qee cov hlau ore nyob rau thaj tsam Pilbara ntawm Australia muaj cov ntsiab lus hlau siab txog 62% - 65%, nrog cov ntsiab lus tsis tshua muaj leej faj thiab phosphorus impurity, ua rau lawv cov khoom siv zoo tagnrho rau kev tsim cov nkoj tsim steel phaj.
Lub caij no, lwm cov kab hauv cov ore yuav tsum tau txiav txim siab. Txawm hais tias qee cov kab lus muaj nyob rau hauv me me, lawv yuav muaj kev cuam tshuam rau kev ua haujlwm ntawm cov phaj steel. Piv txwv li, cov khoom xws li titanium (Ti) thiab vanadium (V), yog tias tsim nyog, tuaj yeem ua lub luag haujlwm muaj txiaj ntsig zoo xws li kev ua kom zoo ntawm cov nplej hauv kev ua haujlwm tom ntej. Txawm li cas los xij, yog tias lawv cov ntsiab lus siab dhau los lossis yog tias muaj qee qhov teeb meem kab mob (xws li arsenic (As)), qhov zoo ntawm cov phaj hlau yuav raug txo.

 

 

 

Chemical Pretreatment (Yeem):
Rau qee cov ores nrog cov ntsiab lus impurity siab, chemical pretreatment txoj kev tuaj yeem siv tau. Piv txwv li, rau ores nrog cov ntsiab lus sulfur siab, siv txoj kev roasting desulfurization. Nyob rau hauv qhov kub thiab txias thiab ib qho chaw tshwj xeeb (xws li oxidizing cua), cov sulfides hauv cov ore hnov ​​​​mob nrog oxygen los tsim cov roj sulfur dioxide, uas khiav tawm, yog li txo cov sulfur cov ntsiab lus hauv cov ore. Txawm li cas los xij, txoj kev no muaj tus nqi siab thiab yuav muaj qee yam cuam tshuam rau ib puag ncig, yog li nws yuav tsum tau siv nrog ceev faj.

 

Hais txog Kev Tswj Xyuas Qhov Zoo ntawm Alloy Additives

 

Tus neeg muab kev tshuaj ntsuam xyuas thiab kev teeb tsa zoo:
Cov neeg muab khoom ntawm alloy additives yuav tsum tau soj ntsuam nruj me ntsis. Xaiv cov neeg muag khoom nrog lub koob npe zoo uas tuaj yeem muab cov khoom lag luam ruaj khov thiab ua tau raws li cov qauv siab. Piv txwv li, xav kom cov neeg muag khoom muab cov ncauj lus kom ntxaws txog cov khoom lag luam soj ntsuam zoo, suav nrog cov ntsiab lus ntawm cov ntsiab lus alloy thiab qhov txwv ntau ntawm impurity ntsiab. Rau manganese alloys, ntxiv rau qhov yuav tsum tau hais yav dhau los uas cov ntsiab lus manganese yuav tsum siab dua 75%, cov ntsiab lus sulfur yuav tsum raug txwv rau hauv qab 0.03% thiab cov ntsiab lus phosphorus qis dua 0.04%.
Lub tuam txhab nws tus kheej yuav tsum tsim cov qauv nruj zoo rau cov khoom siv alloy. Cov qauv no yuav tsum siab tshaj qhov yuav tsum tau ua hauv kev lag luam thiab yuav tsum tau hloov kho raws li cov kev xav tau tshwj xeeb ntawm cov nkoj tsim steel phaj. Piv txwv li, rau alloy additives siv nyob rau hauv kev tsim cov high-strength thiab high-toughness shipbuilding steel daim hlau, lub impurity ntsiab uas yuav cuam tshuam rau toughness, xws li arsenic (As) thiab tin (Sn), yuav tsum tau tswj nyob rau hauv ib tug tsawg kawg nkaus theem. .

 

Cov txheej txheem tshuaj xyuas tuaj:
Yuav tsum tsim kom tiav cov txheej txheem tshuaj xyuas. Thaum alloy additives nkag mus rau hauv lub Hoobkas, yuav tsum tau ua tiav kev tshuaj xyuas. Ua ntej, kev tshuaj xyuas qhov muag yuav tsum tau ua los xyuas seb puas muaj cov impurities pom tseeb, agglomeration, thiab lwm yam. Tom qab ntawd, kev tshuaj xyuas tshuaj yuav tsum tau ua los ntawm cov cuab yeej tshuaj ntsuam xyuas meej (xws li spectrometers) txhawm rau txiav txim siab cov ntsiab lus ntawm cov ntsiab lus alloy thiab impurity ntsiab kom paub meej tias lawv ua tau raws li cov qauv zoo tsim los ntawm lub tuam txhab. Yog tias qhov kev soj ntsuam tsis ua tiav, cov additives yuav tsum tau muab pov tseg kom ruaj khov los tiv thaiv cov additives uas tsis tsim nyog nkag mus rau hauv cov txheej txheem ntau lawm.

 

Kev Tswj Cia:
Tsim nyog kev tswj hwm ntawm alloy additives yuav tsum tau nqa tawm. Sib txawv alloy additives yuav tsum tau khaws cia nyias kom tsis txhob muaj kev sib kis. Qhov chaw khaws cia yuav tsum tau khaws cia kom qhuav thiab zoo-ventilated los tiv thaiv cov additives los ntawm damp, oxidized, thiab lwm yam. Piv txwv li, niobium (Nb) alloy additives tej zaum yuav oxidized nyob rau hauv ib tug ntub ib puag ncig, txo cov ntsiab lus ntawm lawv active Cheebtsam, yog li tshwj xeeb. kev saib xyuas yuav tsum tau them rau cov xwm txheej khaws cia. Lub caij no, cov ntaub ntawv khaws cia yuav tsum tau khaws cia kom zoo, thiab kev nkag thiab tawm ntawm cov khoom siv ntxiv yuav tsum tau sau npe kom meej rau kev taug qab cov teeb meem zoo.
