Xav txog cov tshuaj Chemical Composition thiab Initial Microstructure ntawm Steel Phaj

 

Cov nyhuv ntawm Chemical Composition: Cov tshuaj muaj pes tsawg leeg ntawm CCS E550 steel phaj muaj qhov cuam tshuam tseem ceeb ntawm cov txheej txheem kev ua haujlwm tsis zoo. Piv txwv li, cov ntsiab lus ntawm alloying ntsiab xws li manganese (Mn), chromium (Cr), thiab npib tsib xee (Ni) tuaj yeem hloov pauv qhov tseem ceeb (xws li Ac1, Ac3) kub ntawm cov hlau. Yog tias cov ntsiab lus ntawm cov ntsiab lus alloying siab, Ac3 kub yuav nce. Nyob rau hauv cov ntaub ntawv no, lub normalizing cua sov kub kuj yuav tsum tau nce raws li kom ntseeg tau tias ferrite yog kiag li hloov mus rau hauv austenite. Lub caij no, cov ntsiab lus carbon kuj tseem ceeb. Cov ntsiab lus carbon ntau dua tuaj yeem ua rau muaj zog dua tom qab normalizing, tab sis nws kuj tseem tuaj yeem cuam tshuam cov tawv nqaij. Yog li ntawd, kho qhov normalizing kub raws li cov tshuaj muaj pes tsawg leeg yog thawj kauj ruam hauv kev txiav txim siab txoj kev pom.

 

Reference ntawm Initial Microstructure: Thawj qhov microstructure ntawm cov hlau phaj (xws li seb nws puas tau dhau los ua forging, dov, los yog ua ntej kev kho cua sov) tuaj yeem cuam tshuam cov txheej txheem normalizing. Yog tias cov phaj hlau tau ua tiav thiab deformed yav dhau los thiab muaj qhov sib txawv loj heev los yog tsis yog cov qauv microstructure sab hauv, nws yuav tsim nyog kom tsim nyog ncua sij hawm tuav lub sij hawm normalizing kom tag nrho homogenize microstructure. Piv txwv li, rau CCS E550 steel phaj uas tau dhau los dov nrog qhov loj deformation, nws cov nplej sab hauv yuav raug elongated raws li cov kev taw qhia dov, thiab lub sij hawm tuav txaus yuav tsum tau thaum lub sij hawm normalizing kom tshem tawm cov microstructure tsis sib xws.

 

Ua Kev sim ua kom zoo li qub thiab kuaj kev ua haujlwm

 

Tsim Cov Me Me - Batch Experiments: Ua ntej kev tsim khoom tiag tiag, me me - batch sim normalizing kev kho mob yuav tsum tau ua ua ntej. Kev sib txawv ntawm cov cua kub kub, tuav lub sij hawm, thiab cov cua txias tuaj yeem raug xaiv kom normalizing me me - loj CCS E550 steel phaj qauv. Piv txwv li, cov cua kub kub tuaj yeem teem caij los ntawm 30 degree saum Ac3 txog 80 degree saum Ac3, thiab lub sijhawm tuav tuaj yeem nyob ntawm 10 feeb mus rau 60 feeb. Cov txheej txheem cua txias sib txawv xws li huab cua ntuj - cua txias lossis cua txias - cua txias tuaj yeem xaiv.

 

Cov khoom ntsuas kev ua tau zoo: Kev ntsuam xyuas kev ua tau zoo yuav tsum tau ua ntawm cov qauv tom qab kev sim normalizing kev kho mob. Ua ntej, kev ntsuam xyuas cov cuab yeej cuab tam suav nrog kev ntsuas tensile los txiav txim siab lub zog tawm los, lub zog tensile, thiab elongation los ntsuas lub zog thiab tawv ntawm cov phaj steel. Qhov kev sim hardness tuaj yeem txais yuav Rockwell hardness lossis Brinell hardness kuaj txoj hauv kev kom nkag siab txog qhov hardness hloov ntawm steel phaj tom qab normalizing. Tsis tas li ntawd, qhov kev ntsuam xyuas toughness tuaj yeem ua tiav. Charpy impact test yog siv los txheeb xyuas qhov cuam tshuam ntawm cov hlau phaj ntawm qhov sib txawv ntawm qhov kub thiab txias, uas yog ib qho tseem ceeb heev rau daim ntawv thov scenarios uas yuav tsum tau tiv taus dynamic loads.
