6515 Cov pa roj ntau ntxiv rau steelmaking

6515 Cov pa roj carbon silicon siv rau steelmaking feem ntau yog hais txog cov pa roj carbon monoyes yog kwv yees li 65% thiab cov pa roj caricon yog kwv yees li 15%. Nws yog tsuas yog tsim ntawm silicon (si) thiab carbon (c), thiab tej zaum yuav muaj ib qho me me ntawm txhuas (ib qho), phosphorus (p), leej faj (thiab lwm yam impurities. Nws feem ntau yog nyob rau hauv daim ntawv pob lossis granular, nrog nyiaj - grey xim hlau luster rau saum npoo. Nws muaj cov oxidation zoo ua kom tsis kam thiab corrosion tsis kam, tuaj yeem ruaj khov nyob rau ntawm qhov kub, thiab muaj qhov nthuav dav tsawg thiab zoo thermal stability.

Nws yog tsim nyog rau smelting ntawm ntau hom hlau, suav nrog cov hlau ua tib zoo li qub, nruab nrab cov roj hlau hlau, nruab nrab cov roj hlau hlau, cov hlau ua kom zoo, thiab lwm yam.

Siab tus nqi - ua tau zoo:

Nws tuaj yeem hloov cov khoom kim heevDeagidizersxws liferrosiliconthiab calcium carbide. Nws tuaj yeem ib txhij ib txhij, nce silicon thiab nce cov pa roj carbon ntau, ua kom siv ntau yam ntxiv, yog li txo tus nqi ntawm steelmaking.

Zoo tau txais kev ua tau zoo:

Nws tsis tsuas yog muaj zog deoxidation muaj peev xwm, tab sis kuj txhawb cov dej ntawm Molten Steel Purer. Nws cov nyhuv sib sau yog qhov tseem ceeb, uas tuaj yeem ua rau cov txheej txheem statmipate, pab txhawb kev haus dej thiab kho kom zoo thiab ntom ntawm cov hlau. Deoxidizers tsuas yog tsom rau deagidation muaj nuj nqi, thiab kev txhim kho ntawm lwm cov khoom ntawm Molten Steel yog tsawg tsawg.

Tus Nqi Them Ruaj Ntseg:

Nws tau muaj cov tshuaj siv lub cev muaj zog thiab tshuaj ceev, siab ceev, siab purity, thiab muaj peev xwm tswj tau tus nqi siab thiab ruaj khov thaum cov txheej txheem statmaking. Qhov no ua rau cov txheej txheem tswj hwm hauv cov txheej txheem statmaking ntau dua thiab txo cov teeb meem ntawm cov tawv nqaij tsis ruaj khov tshwm sim los ntawm kev rov ua dua ntawm deoxidization. Nyob rau hauv kev sib piv, muaj ib txwm deoxidizers xws li txhuas yog nquag mus rau cov pa roj thaum lub sij hawm mathgaking, ua rau muaj kev tswj hwm tsis ruaj khov thiab cuam tshuam rau kev tswj hwm cov hlau zoo.

Kev tiv thaiv ib puag ncig zoo:

Thaum lub sijhawm tsim khoom thiab siv, 6515 hc silicon tsim cov kuab paug ntawm ob peb paug. Nws tsis ua rau cov hlau tsis muaj zog, txo cov khoom uas muaj kev phom sij thaum muaj kev tiv thaiv kev tiv thaiv kev lag luam ib puag ncig. Deoxidizers xws li Calcium Carbide yuav ua cov roj teeb meem xws li acetylene thaum siv, ua rau qee qhov kev qias neeg.

Deoxidation:

Thaum lub sij hawm cov txheej txheem statmaking, qee qhov nqi ntawm cov pa oxygen yog inevitably tam sim no hauv Molten Steel. Lub xub ntiag ntawm cov pa tuaj yeem cuam tshuam rau cov hlau zoo, txo nws lub zog thiab tawv thiab ua rau tsis xws luag thiab xoob. Cov silicon hauv 6515 siab}} pabon fiber silic silicity rau oxygen, sai sai reacting tshuaj los ua silicon dioxide (sitio). Cov tshuaj tiv thaiv kev siv tshuaj yog: Si + ₂=sio₂. Lub txiaj ntsig silicon dioxide muaj qhov ntom ntom ntom thiab nce mus rau saum npoo ntawm cov hlau molten li slag, zoo heev tshem tawm cov kev coj dawb huv thiab kev ua kom zoo.

Carburization:

Cov pa roj carbon yog qhov tseem ceeb hauv kev txiav txim siab steel cov khoom. Cov hlau nrog cov roj carbon sib txawv ua kom pom cov yam ntxwv sib txawv. Cov pa roj carbon hauv 6515 high - pa roj carbon si hauv cov qauv roj hmab uas xav tau txhim kho lub zog, Hardness, thiab lwm yam khoom. Thaum lub sij hawm steelmaking, unoxidized cov pa roj carbon dissolves hauv cov qauv steel, yog li ua kom zoo dua ntawm cov qauv steel, xws li txhim kho lub zog ntawm cov roj carbon monoxide, xws li kev txhim kho lub zog ntawm cov roj carbon monoxide, xws li kev txhim kho lub zog ntawm cov roj carbon monoxide, xws li kev txhim kho lub zog ntawm cov roj carbon monoxide, xws li kev txhim kho lub zog ntawm cov qauv hlau.

Cov nyhuv alhoying:

Ntxiv nrog rau deoxidation thiab carburization, 6515 siab} pabon sawbon kuj tseem tuaj yeem ntxiv rau cov khoom siv roj av, hloov kho nws cov microstructure thiab cov khoom. Silicon yaj nyob rau hauv ferrite ua ntxiv dag zog zog, nce cov hlau lub zog thiab hardness thaum tseem ua rau nws elasticity. Thaum tsim cov high- Lub zog alloy, cov txheej txheem sib txawv, thiab kev sib ntsib ntawm txoj hlua hluav taws xob, thiab kev sib ntsib ntawm txoj hlua khi rau cov hlau ua kom zoo rau hauv ntau yam kev siv.
