6515 High Carbon Silicon Rau Steelmaking

6515 siab carbon silicon siv rau steelmaking feem ntau yog hais txog carbon silicon alloy, nyob rau hauv uas cov ntsiab lus silicon yog hais txog 65% thiab cov ntsiab lus carbon yog hais txog 15%. Nws yog tsim los ntawm silicon (Si) thiab carbon (C), thiab tej zaum yuav muaj ib tug me me ntawm txhuas (Al), calcium (Ca), hlau (Fe) thiab lwm yam, raws li zoo raws li tus nqi ntawm manganese (Mn), phosphorus (P), sulfur (S) thiab lwm yam impurities. Nws feem ntau yog nyob rau hauv pob los yog granular daim ntawv, nrog ib tug silver - grey metallic luster nyob rau saum npoo. Nws muaj qhov zoo oxidation tsis kam thiab corrosion kuj, tuaj yeem nyob ruaj khov ntawm qhov kub thiab txias, thiab muaj qhov sib txawv qis thiab zoo thermal stability.

Nws yog tsim rau smelting ntawm ntau hom hlau, nrog rau cov pa roj carbon zoo tib yam, siab - zoo carbon steel, alloy structural steel, aluminium static steel, vuam fwj steel, nruab nrab carbon alloy structural steel, weathering steel, thiab lwm yam.

Tus nqi siab -kev ua tau zoo:

Nws tuaj yeem hloov pauv qee yam uas kim heevcov deoxidizersxws liferrosiliconthiab calcium carbide. Nws tuaj yeem ua ib txhij deoxidize, nce silicon thiab nce carbon, txo kev siv ntau yam khoom ntxiv, yog li txo tus nqi ntawm steelmaking.

Kev ua tau zoo qhia dav:

Nws tsis tsuas yog muaj zog deoxidation muaj peev xwm, tab sis kuj txhim kho cov fluidity ntawm molten steel thiab ua rau cov hlau molten purer. Nws cov nyhuv slag sau yog qhov tseem ceeb, uas tuaj yeem sib sau ua ke oxides sai sai hauv cov txheej txheem steelmaking, pab lim thiab kho, thiab txhim kho qhov zoo thiab ntom ntawm cov hlau. Ib txwm deoxidizers tsuas yog tsom rau kev ua haujlwm deoxidation, thiab kev txhim kho ntawm lwm yam khoom ntawm cov hlau molten yog qhov txwv.

Stable rov qab tus nqi:

It has stable physical and chemical properties, high density, high purity, and can maintain a high and stable recovery rate during the steelmaking process. Qhov no ua rau kev tswj xyuas muaj pes tsawg leeg hauv cov txheej txheem steelmaking ntau qhov tseeb thiab txo qhov teeb meem ntawm cov hlau tsis ruaj khov uas tshwm sim los ntawm kev hloov pauv ntawm qhov rov qab ntawm deoxidizer. Nyob rau hauv sib piv, qee cov tshuaj deoxidizers xws li txhuas yog nquag hnov ​​​​mob nrog oxygen nyob rau hauv cov huab cua thaum lub sij hawm steelmaking txheej txheem, ua rau tsis ruaj tsis khov cov nqi rov qab thiab cuam tshuam rau kev tswj cov hlau zoo.

Kev tiv thaiv ib puag ncig zoo:

Thaum lub sijhawm tsim khoom thiab siv, 6515 HC silicon tsim cov pa phem tsawg. Nws tsis ua phem rau cov hlau molten, txo cov tiam thiab emission ntawm cov khoom tsis zoo thaum lub sij hawm steelmaking, thiab ua tau raws li kev tiv thaiv ib puag ncig ntawm kev lag luam steel niaj hnub. Cov tshuaj deoxidizers xws li calcium carbide yuav tsim cov pa phem xws li acetylene thaum siv, ua rau qee qhov ua paug rau ib puag ncig.

Deoxidation:

Thaum lub sij hawm steelmaking txheej txheem, ib tug tej yam nqi ntawm oxygen yog inevitably muaj nyob rau hauv cov hlau molten. Lub xub ntiag ntawm oxygen tuaj yeem cuam tshuam rau cov hlau zoo, txo nws lub zog thiab tawv thiab ua rau muaj qhov tsis xws luag xws li porosity thiab looseness. Lub silicon nyob rau hauv 6515 siab-carbon silicon muaj ib tug muaj zog affinity rau oxygen, sai heev reacting chemically tsim silicon dioxide (SiO₂). Cov tshuaj tiv thaiv kab mob sib npaug yog: Si + O₂=SiO₂. The resulting silicon dioxide has a low density and rises to the surface of the molten steel as slag, effectively removing it and deoxidizing the steel, significantly improving its purity and quality.

Carburization:

Cov pa roj carbon monoxide yog lub hauv paus tseem ceeb hauv kev txiav txim siab cov khoom steel. Cov hlau uas muaj cov ntsiab lus sib txawv ntawm cov pa roj carbon monoxide muaj cov yam ntxwv ua tau zoo. Cov pa roj carbon nyob rau hauv 6515 siab-carbon silicon plays lub luag haujlwm tseem ceeb hauv qib steel uas xav tau cov ntsiab lus carbon ntau dua los txhim kho lub zog, hardness, thiab lwm yam khoom. Thaum lub sij hawm steelmaking txheej txheem, unoxidized carbon dissolves nyob rau hauv lub molten steel, zoo ua rau cov hlau cov pa roj carbon ntsiab lus kom tau raws li cov ntsiab lus carbon cov ntsiab lus ntawm cov steel qib, yog li optimizing cov hlau kev ua tau zoo, xws li kev txhim kho lub zog thiab hnav tsis kam ntawm cov qauv steel.

Alloying nyhuv:

Ntxiv nrog rau deoxidation thiab carburization, 6515 siab -carbon silicon kuj tuaj yeem muab ntxiv rau cov hlau ua cov hlau alloying, hloov pauv nws cov microstructure thiab cov khoom. Silicon yaj nyob rau hauv ferrite tsim cov khoom muaj zog ntxiv zog, ua rau cov hlau lub zog thiab hardness thaum tseem txhim khu nws elasticity. Thaum tsim high-lub zog alloy steels, caij nplooj ntoos hlav steels, thiab lwm yam qib, qhov tsim nyog ntxiv ntawm 6515 siab-carbon silicon precisely kho cov hlau cov tshuaj muaj pes tsawg leeg, uas ua rau lub zuag qhia tag nrho kev ua tau zoo thiab ua tau raws li cov kev cai nruj rau steel kev ua tau zoo nyob rau hauv ntau yam kev siv.
