Nrig Ferro Silicon
Ferrosilicon yog lub zog ntawm cov hlau thiab silicon. Ferrosilicon yog ib hom hlau-silicon alloy, uas yog tsim los ntawm coke, steel chips, quartz (lossis silica) thiab smelted los ntawm hluav taws xob cua sov.
Ferrosilicon yog lub zog ntawm cov hlau thiab silicon. Ferrosilicon yog ib hom hlau-silicon alloy, uas yog tsim los ntawm coke, steel chips, quartz (lossis silica) thiab smelted los ntawm hluav taws xob cua sov. Vim tias silicon thiab oxygen tuaj yeem yooj yim ua ke los ua silicon dioxide, ferrosilicon feem ntau yog siv los ua deoxidizer hauv kev tsim cov hlau, thiab txij li kev tsim cov SIO2 muab tawm ntau qhov kub, nws tau txais txiaj ntsig los ua kom kub ntawm molten steel thaum deoxidizing. Nyob rau tib lub sijhawm, ferrosilicon tuaj yeem siv los ua alloying element additive nyob rau hauv qis alloy qauv hlau, caij nplooj ntoos hlav steel, cov kabmob hlau, hlau tsis kam tiv tshav kub thiab hluav taws xob silicon hlau.
Siv los ua deoxidizer thiab alloying tus neeg saib xyuas hauv kev tsim cov hlau ua haujlwm. Yuav kom tau txais cov hlau nrog cov tshuaj lom neeg tsim nyog thiab xyuas kom zoo ntawm cov hlau, deoxidation yuav tsum tau nqa tawm ntawm theem kawg ntawm kev tsim cov hlau. Cov tshuaj sib xyaw ua ke ntawm silicon thiab oxygen yog qhov loj heev, yog li ferrosilicon yog lub zog deoxidizer rau kev tsim steel thiab yog siv rau nag lossis daus thiab diffusion deoxidation. Qhov sib ntxiv ntawm qee qhov nqi ntawm silicon rau steel tuaj yeem txhim kho lub zog, tawv thiab elasticity ntawm cov hlau, yog li ntawd, ferrosilicon tseem siv los ua alloying tus neeg sawv cev hauv smelting cov txheej txheem steel (0.40-1.75% silicon, cuab tam steel (Sio. 30-) 1.8%), lub caij nplooj hlav hlau (Sio. 40-2.8%) thiab transformer steel (SI 2.81-4.8%). Tib lub sijhawm, nws yog cov cuab yeej tshiab los txhim kho cov hlau tsis zoo, txo tus nqi thiab txuag kev siv ntawm cov hlau los ntawm kev txhim kho cov duab ntawm kev koom ua ke thiab txo cov ntsiab lus ntawm cov pa roj hauv cov hlau ua kua. Nws tshwj xeeb tshaj yog tsim rau Deoxidization ntawm kev nruam casting molten steel. ntawm desulfurization, lub siab nqus thiab muaj zog nkag.
Tsis tas li ntawd, hauv kev lag luam tsim cov hlau, ferro-silicon hmoov tuaj yeem muab cov cua sov ntau los ntawm qhov kub ntawm qhov kub, uas feem ntau siv los ua tus neeg sawv cev cua sov ntawm Ingot cap los txhim kho qhov zoo thiab rov qab los ntawm Ingot.
