♦ Rau hmoov thiab granules, cov muaj pa roj caricon silicon feem ntau tau ntim rau hauv cov hnab yas lossis ntawv sib txawv ntawm 25 kg rau 1 tuj, nyob ntawm seb tus neeg yuav tsum tau ua. Cov hnab no tuaj yeem ntim ntxiv rau hauv lub hnab loj lossis ntim rau kev xa khoom.

♦ Rau briquettes thiab qog, cov pa roj caricon ntau ntau ntim hauv cov hnab yas lossis cov lus sib txawv nrog ntau dua 25 kg mus rau 1 tuj. Cov hnab no feem ntau stacked ntawm pallets thiab qhwv nrog zaj duab xis yas rau kev thauj mus los nyab xeeb

 

Cov pa roj carbon ntau yog qhov tseem ceeb me me, mas suav nrog ntawm silicon thiab carbon thiab siv tau siv hauv cov hlau thiab muaj kev lag luam. Nws cov tshuaj muaj kuab lom ua rau nws ua si ntau lub luag haujlwm hauv cov txheej txheem smelting, pab ua ib qho alloy addutive, deoxidizer thiab inoculant. Piv nrog zoo ib yam ferrosilicon alloys, muaj cov pa roj carbon silicon muaj cov ntsiab lus muaj roj carieve, uas muab nws cov txiaj ntsig tshwj xeeb hauv qee cov txheej txheem tshwj xeeb.

 

 

Nyob rau hauv steel smatting, lub ntsiab muaj nuj nqi ntawm cov pa roj carbon silicon yog deoxidation thiab kev sib dhos. Silicon muaj kev sib txawv nrog cov pa oxygen thiab tuaj yeem tshem tawm cov pa oxygen dawb hauv Molten Hlau, thiab txhim kho cov roj paug oxide, thiab txhim kho cov pa purity. Nyob rau tib lub sijhawm, silicon kuj tseem tuaj yeem txhim kho lub zog thiab hardness ntawm steel thiab txhim kho nws cov khoom siv neeg. Cov carbon lub caij nyob rau hauv cov pa roj carmoo silicon pab kom kho cov qauv hlau, tshwj xeeb tshaj yog thaum muaj ntau cov pa roj carbon monoxide, nws tuaj yeem siv lwm cov kev siv lwm cov pa roj carbon. Tsis tas li ntawd, tus nqi ntawm cov pa roj carbon ntau dua yog qhov tsawg, uas tuaj yeem txo cov nqi ntau lawm thaum ua kom zoo. Nyob rau hauv lub foundry kev lag luam, cov pa roj carbon ntau feem ntau siv los ua cov inoculant los txhim kho cov qauv thiab cov khoom ntawm cov hlau cam khwb cia. Cov hlau nrum hlau yog qhov tsis tshua muaj duab ya thaum lub suab nrov nrov thaum lub zog, uas cuam tshuam rau nws lub zog thiab tawv. Tom qab ntxiv cov pa roj ntau ntxiv, silicon tuaj yeem txhawb nqa cov khoom faib khoom lag luam zoo nkauj dua, yog li kev txhim kho nws lub zog tensile thiab hnav tsis kam. Nyob rau tib lub sijhawm, qhov sib ntxiv ntawm cov carbon elements tuaj yeem ruaj khov cov tshuaj muaj zog ntawm cam khwb cia hlau, txo cov cam khwb cia, thiab txhim kho cov txiaj ntsig ntawm cov khoom siv.

 

 

Cov txheej txheem ntau lawm ntawm cov pa roj carbon silicon yog yooj yim. Nws ib txwm yog smelted nyob rau hauv ib submerged arc rauv nrog silica thiab coke raws li lub ntsiab raw cov ntaub ntawv. Raws li cov kev mob siab, cov silicon dioxide hauv cov sillica yog txo thiab sib xyaw ua ke nrog cov pa roj carlicon. Tus txheej txheem no muaj qee qhov yuav tsum tau ua rau cov khoom siv raw thiab cua sov tswj kom paub tseeb tias qhov kev ruaj ntseg ntawm cov khoom ntawm cov khoom kawg. Vim tias qhov qis melting point ntawm cov pa roj carlicon, lub smelting zog siv yog qhov me me, uas ua rau nws muaj kev lag luam ntawm cov ntaub ntawv metallurgical. Txawm hais tias cov pa roj carbon ntau muaj ntau yam kev siv, nws tseem tsim nyog kom them sai sai rau nws cov txiaj ntsig carbon cov ntsiab lus ntawm cov khoom kawg thaum siv nws. High cov ntsiab lus carbon yuav ua rau kev ua tau zoo ntawm cov hlau lossis cov hlau pov tseg kom raug suav los ntawm cov kev cia siab, yog li cov piv yuav tsum tau xam thaum ntxiv nws.
