Nyob hauv lub ntiaj teb ntawm Metallurgy,FERRO Silicon 75ua lub luag haujlwm tseem ceeb. Nws qhov zoo yog kev txiav txim siab zoo nyob rau hauv yuav ua li cas zoo nws tuaj yeem siv tau nyob rau hauv ntau cov txheej txheem metallurgical. Cov lus no rho mus tob rau hauv cov kev sib sib zog nqus ntawm FESI 75 ua tau zoo thiab lawv qhov kev cuam tshuam rau metallurgy.
Silicon Cov Ntsiab Lus: Lub ntsiab lus tseem ceeb
Silicon yog qhov tseem ceeb tshaj plaws thiab tseem ceeb tshaj plaws hauv Ferro Silicon 75% thaum nws los txog nws daim ntawv thov hauv Metallurgy. Cov ntsiab lus ntau silicon siab dua txhim kho nwsdeoxidationmuaj peev xwm. Hauv cov hlau - ua cov txheej txheem, piv txwv li, cov cuab yeej no yog qhov tseem ceeb tshaj plaws. Thaum 75 Ferro silicon nrog cov ntsiab lus silicon siab yog ntxiv rau Molten hlau, nws nrawm nrawm nrog cov pa tawm hauv cov hlau. Qhov tshuaj tiv thaiv no cov ntawv silicon dioxide, uas tuaj yeem tshem tawm yooj yim li slag. Raws li ib tug tshwm sim, cov ntsiab lus oxygen hauv cov hlau yog txo qis, ua rau lub tshuab nqus tsev huv thiab purer steel. Lub tshuab ua kom zoo nkauj, nyob rau hauv lem, ua kom pom cov khoom zoo dua xws li nce lub zog, txhim kho kev ua kom muaj zog, thiab ua kom haum corrosion.
Ntxiv mus, kev ruaj ntseg ntawm cov ntsiab lus silicon hauv 75 fesi yog qhov tseem ceeb sib luag. Qib silicon muaj peev xwm ua me me me me ntawm cov txheej txheem ua kom raug. Kho kom meej tswj tau cov txheej txheem alloy yog qhov tseem ceeb rau kev tsim cov hlau nrog kev ua kom zoo ib yam thiab cov khoom siv tau. Hloov pauv hauv cov ntsiab lus silicon tuaj yeem ua rau tsis sib xws alloying, ua rau nws nyuaj kom tau raws li cov qauv nruj ua kom tau zoo rau cov qauv hlau sib txawv.
Cov ntsiab lus tsis raug kaw: tus nqi zais zais
Cov kev phom sij xws li Sulphur thiab Phosphorus
Sulphurur thiab phosphorus yog ob lub ntsiab uas tuaj yeem muaj cov nyhuv ua paug ntawm cov hlau zoo thaum muaj ntau yam nyob hauv Ferro Silicon 75 hauv ntau dhau. Sulphur muaj qhov nyiam ua rau kub brittleness hauv cov hlau. Thaum kub - ua haujlwm cov txheej txheem xws li forging lossis dov, steel nrog cov ntsiab lus faj sulfur siab dua li yuav tawg. Qhov no txo tau tag nrho cov tshuab sib luag ntawm cov hlau thiab txwv nws cov ntawv thov. Phosphorus, ntawm qhov tod tes, ua rau txias brittleness. Steel muaj qib siab ntawm phosphorus dhau los ua lub qhov kub thiab txias, nce txoj kev pheej hmoo ntawm qhov chaw ua haujlwm tsis txias.
Lwm cov ntsiab: Aluminium thiab calcium
Thaum txhuas thiab calcium tuaj yeem muaj cov teebmeem zoo hauv kev sim, lawv muaj ntau lub hauv paus lossis cov qib tsis sib xws hauv Ferro Silicon 75% tuaj yeem ua teeb meem. Aluminium yog deoxidization muaj zog thiab tuaj yeem txhim kho cov deoxidation nyhuv hauv cov hlau - ua cov txheej txheem. Txawm li cas los xij, yog tias cov ntsiab lus txhuas ntau dhau, nws tuaj yeem nce viscosity ntawm Molten hlau. Qhov no ua rau nws nyuaj rau ncuav cov hlau ua pwm rau hauv cov pwm thaum ua pov, muaj peev xwm ua rau tsis xws luag nyob rau hauv cov khoom kawg. Cov tshuaj calcium, txawm hais tias nws tuaj yeem txhim kho cov morphology thiab faib cov suav nrog hauv cov hlau, yuav tsum tau ua tib zoo tswj hwm. Cov theem txwv tsis pub muaj cov tshuaj calcium yuav cuam tshuam tau cov tshuaj ib txwm muaj nyob rau hauv lub cub tawg thiab cuam tshuam rau cov khoom lag luam zoo ntawm cov hlau.
Loj faib: Qhov teeb meem ntawm cov tshuaj tiv thaiv efficiency
Qhov loj ntawm Fesi 75 muaj qhov cuam tshuam tseem ceeb ntawm nws cov tshuaj tiv thaiv kev ua haujlwm hauv cov cub hluav taws xob me me. Qhov kev tsim nyog qhov tsim nyog kom ua rau muaj kev tawg ua kom tiav hauv cov hlau Molten. Thaum 75% Ferrro silicon hais yog qhov loj me, lawv muaj peev xwm faib cov hlau, ua kom muaj ntau lub chaw tiv tauj nrog cov hlau molten. Qhov no ua rau muaj kev tiv thaiv ntau dua, tso cai rau kev deoxidation zoo dua thiab kev siv.
Yog hais tias cov lus tshaj ntawd loj dhau, thaj chaw tiv tauj nrog Molten Steel yog txwv. Qhov no ua rau tus nqi txo qis qis, thiab Ferro Silic Silicon 75 tej zaum yuav tsis muaj peev xwm ua kom muaj kev mob siab rau lub sijhawm. Raws li lub txim, lub deoxidation thiab cov kev sib txuam yuav ua tsis tiav, cuam tshuam qhov zoo ntawm cov khoom kawg steel kawg. Hloov siab, yog hais tias cov lus me me dhau heev, lawv feem ntau yuav tau nqa mus los ntawm cov pa roj hauv cov cua sov, ua rau cov khoom poob. Ib qho ntxiv, cov khoom zoo heev yuav ua rau hauv zos dhau los - kev tawm tsam, cuam tshuam kev ruaj ntseg ntawm cov txheej txheem metallurgical.
Hauv kev xaus, qhov zoo ntawm Ferro silicon 75, suav nrog cov lus sib dhos li Silicon, thiab qhov loj me, muaj qhov cuam tshuam loj rau nws cov kev ua tau zoo hauv cov txheej txheem metallurgical. Kev ua kom tiav siab - zoo Ferro Silica 75 yog qhov tseem ceeb rau kev tsim cov khoom lag luam siab - cov khoom siv zoo thiab lwm yam khoom siv hlau nrog cov khoom siv tshwj xeeb thiab ntseeg tau.
