Silicon Aluminium Calcium Alloy

Taw qhia

Silicon Aluminium Calcium Alloy muaj zog affinity nrog oxygen, sulfur, hydrogen, nitrogen thiab carbon nyob rau hauv molten steel, yog li nws feem ntau yog siv raws li Oxygen scavenger thiab desulfurizer. Tsis tas li ntawd, ntxiv cov khoom no rau cov hlau molten tuaj yeem ua kom muaj zog exothermic, uas yog qhov zoo rau kev tswj xyuas qhov kub ntawm cov hlau molten. Calcium vapor kuj muaj cov nyhuv nplawm ntawm cov hlau molten, uas yog qhov tsim nyog rau cov ntab ntawm cov tsis yog xim hlau. Hauv kev tsim cov cam khwb cia hlau, silicon calcium alloy muaj txiaj ntsig zoo hauv kev txhim kho cov khoom ntawm cam khwb cia hlau dua li cov hlau silicon. Cov khoom no tsis yog tsuas yog ib qho zoo inoculant los txhawb kev tsim ntawm nodular graphite, tab sis kuj muaj lub luag haujlwm ntawm deoxidation, desulfurization, denitrification, thiab silicon li. Peb tau koom nrog hauv kev lag luam no tau ntau xyoo, nrog kev paub nplua nuj thiab kev paub tab, yog li koj tuaj yeem sab laj nrog peb yog tias koj muaj lus nug.

Cov khoom no feem ntau yog siv los ua Oxygen scavenger thiab desulfurizer hauv steelmaking. Calcium thiab sulfur yuav tsim ib tug ruaj khov compound CaS uas yog insoluble nyob rau hauv molten hlau. Ntxiv nrog rau magnesium thiab cov hlau tsis tshua muaj hauv ntiaj teb, calcium kuj tuaj yeem txo cov pa oxygen thiab sulfur uas cuam tshuam kev tsim cov graphite kheej kheej. Cov khoom no tuaj yeem zam qhov teeb meem ntawm nodulation thiab blockage ntawm lub ladle nozzle. Kev kho cov hlau molten nrog cov khoom no tuaj yeem txhim kho lub cev thiab tshuaj lom neeg ntawm cov hlau, nrog rau kev ua kom huv ntawm cov khoom xws li oxides thiab sulfides. Cov khoom no tsis tsuas yog muaj zog deoxygenation muaj peev xwm. Thiab nws kuj txhim kho kev ua haujlwm ntawm cov hlau. Txhim kho lub plasticity, cuam tshuam toughness, thiab flowability ntawm steel.

Nta

1. Silicon Aluminium Calcium Alloy muaj ntau yam deoxygenation Cheebtsam, nrog rau cov yam ntxwv ntawm melting point thiab ceev diffusion, uas muaj peev xwm deoxygenate tag nrho thiab txhawb desulfurization.

2. Cov calcium uas nyob hauv cov khoom no tuaj yeem ua tau zoo spheroidize inclusions hauv molten steel, hloov cov duab ntawm cov inclusions, thiab yog li purify cov hlau molten.

3. Cov khoom no yog siv dav hauv cov txheej txheem xws li tapping ceev nyob rau hauv pem hauv ntej ntawm lub cub tawg thiab refining sab nraum lub cub tawg. Nws tuaj yeem txhim kho smelting ceev, txo lub sij hawm smelting, thiab ua lub luag haujlwm tseem ceeb hauv kev txo cov nqi steelmaking.

4. Cov khoom no tsis muaj pa luam yeeb, tsis muaj plua plav, tsis muaj ntxhiab, thiab tsis muaj fluorine, thiab yuav tsis ua rau muaj kev phom sij rau kev noj qab haus huv ntawm cov neeg ua haujlwm.

5. Cov khoom no muaj qhov zoo ntawm cov tsis muaj hygroscopic, tsis crushing, zoo stability, thiab cia yooj yim.

Daim ntawv thov

-Hardener: siv los txhim kho lub cev thiab lub zog ntawm cov hlau alloys.

-Grain Refiner: Siv los tswj kev tawg ntawm ib tus neeg muaju hauv cov hlau los tsim cov txheej txheem zoo dua thiab zoo dua qub.

-Modifiers thiab tshwj xeeb alloys: feem ntau siv los txhim kho lub zog, ductility, thiab workability.

Qhov zoo

Silicon Aluminium Calcium Alloy yog siv los ua lub zog Oxygen scavenger thiab desulfurizer hauv kev tsim cov hlau qib siab, qis carbon steel thiab stainless hlau. Qhov tseeb, ob qho tib si calcium thiab silicon muaj cov tshuaj muaj zog affinity rau oxygen. Tshwj xeeb tshaj yog calcium muaj ib tug muaj zog tshuaj affinity tsis tsuas yog rau oxygen, tab sis kuj rau sulfur thiab nitrogen. Calcium silicon yog siv los tswj cov duab, qhov loj, thiab kev faib tawm ntawm oxide thiab sulfide inclusions, yog li txhim kho cov flowability, processability, ductility, thiab cuam tshuam kev ua tau zoo ntawm cov khoom steel.

Lub hom phiaj

(1) Cov khoom no yog cov khoom siv rau steelmaking. Haum rau deoxidation nyob rau hauv ntau hom steelmaking, tshwj xeeb tshaj yog haum rau converter steelmaking.

(2) Cov khoom yog cov khoom sib xyaw Oxygen scavenger, uas silicon thiab oxygen muaj kev sib raug zoo. Nws reacts tsim silicon dioxide impurities, uas ntab rau saum npoo ntawm cov hlau molten thiab yooj yim tshem tawm.

(3) Cov nyhuv deoxygenation ntawm cov khoom no txo ​​cov kev suav nrog.
