Silicon Carbide Pob
1. Qhov tseeb, silicon yog tib yam li txhuas. Cov oxide muaj cov qauv spinel-hom, thiab cov chav tsev ntawm cov ciam teb nrog cov hlau yog zoo sib xws thiab sib koom ua ke. Cov nplai oxide yog nruj nreem txuas rau cov hlau, txawm tias nws tsis tev tawm txawm tias nyob rau hauv qhov kub thiab txias. Yog li nws muaj zog oxidation tsis kam thiab kub tsis kam, thiab ntxiv rau cov hlau tsis muaj cua sov.
2. Nws yog qhov zoo los txhim kho cov elasticity ntawm cov hlau. Ntxiv 1 mus rau 2% Si rau nruab nrab carbon steel yuav nce σb los ntawm 15 mus rau 20% thaum lub sij hawm quenching thiab tempering, thiab Aku kuj yuav nce, nrog rau σs thiab δ.
65% SiC Briquettes
3. Nws yog qhov zoo los txhawb graphitization hauv steel thiab siv rau refining graphite steel. Cov hlau no tuaj yeem siv los ua cov kabmob, thiab tuaj yeem siv los hloov cov cuab yeej steel los ua cov punches, kos duab tuag, khoov tuag, thiab lwm yam.
4. Nws muaj peev xwm deoxidizing muaj zog thiab yog ib qho kev siv deoxidizer hauv steelmaking. Yog li, cov hlau dav dav muaj Si, thiab nws cov nyiaj tsawg dua lossis sib npaug rau 0.5%.
Ferro Silicon Briquettes
5. Silicon tuaj yeem txo cov anisotropy ntawm cov muaju, ua kom cov hlau nplaum yooj yim dua, thiab txo cov hlau nplaum. Nws kuj tseem tuaj yeem txo qhov kev puas tsuaj ntawm lwm yam impurities hauv steel rau magnetic teb induction. Yog li ntawd, eddy tam sim no poob tuaj yeem txo qis heev. Vim lub brittleness ntawm silicon, cov ntsiab lus ntawm silicon tam sim no ntawm high-silicon steel los xij yog teev kom tsawg dua 4.5%.
6. Silicon tuaj yeem ua rau qeeb qeeb ntawm qhov decomposition ntawm tempered martensite ntawm qhov kub thiab txias. Silicon yog ib qho ferrite tsim. Ntxiv ntau silicon yuav ua rau A- transformation.
