Dab tsi yog txoj kev tshuaj xyuas zoo rau steel coils? Cov txheej txheem kuaj tsis muaj kev puas tsuaj:

 

Mechanical Property Testing

 

Tensile Test
Cov qauv ntawm cov hlau kauj yog ncab los ntawm lub tshuab ntsuas tensile los ntsuas cov cuab yeej cuab yeej ntsuas xws li lub zog tawm los, lub zog tensile, thiab elongation. Thaum lub sij hawm qhov kev xeem, cov qauv yog tsau rau ntawm lub grips ntawm lub tensile xeem tshuab, thiab ib tug tensile quab yuam yog siv nyob rau hauv ib tug tej yam ceev kom txog rau thaum cov qauv fractures. Lub zog tawm los yog qhov kev ntxhov siab uas cov khoom pib muaj qhov pom tseeb ntawm cov yas deformation. Lub zog tensile yog qhov siab tshaj plaws uas cov khoom tuaj yeem tiv taus ua ntej tawg, thiab elongation qhia txog cov khoom siv yas deformation muaj peev xwm. Cov ntsuas no yog qhov tseem ceeb heev rau kev ntsuas lub load - bearing peev xwm thiab deformation kev ua tau zoo ntawm steel kauj hauv kev siv tswv yim. Piv txwv li, steel coils siv nyob rau hauv kev tsim kho, mechanical manufacturing thiab lwm yam kev lag luam yuav tsum tau raws li tej yam yuav tsum tau rau yield zog thiab elongation.

 

Impact Test
Nws yog tsuas yog siv los ntsuam xyuas lub toughness ntawm steel kauj, tshwj xeeb tshaj yog lub toughness nyob rau hauv ib tug tsawg - kub ib puag ncig. Cov qauv tsis zoo yog raug rau ib qho kev cuam tshuam dabtsi yog khoov los ntawm lub tshuab kuaj qhov cuam tshuam, thiab lub zog nqus tau thaum cov khoom tawg tau sau tseg. Qhov loj ntawm qhov cuam tshuam - lub zog nqus tau tuaj yeem cuam tshuam lub peev xwm ntawm cov hlau kauj los tiv thaiv kev puas tsuaj thaum raug cuam tshuam. Nyob rau hauv lub tsev tsim nyob rau hauv ib co cheeb tsam txias los yog cov neeg kho tshuab Cheebtsam uas yuav tsum tau tiv thaiv dynamic tej yam kev mob, tej yam toughness ntawm steel kauj yog heev yuav tsum tau. Piv txwv li, nws yog ib qho tsim nyog yuav tsum tswj kom muaj zog txaus ntawm qhov kub thiab txias los tiv thaiv cov khoom ntawm brittle fracture.

Hardness Test
Hardness yog ib qho kev ntsuas ntawm lub peev xwm ntawm steel kauj los tiv thaiv lub zos deformation. Feem ntau - siv hardness - kuaj cov qauv suav nrog Brinell hardness (HB), Rockwell hardness (HR), thiab Vickers hardness (HV). Piv txwv li, hauv Brinell hardness test, lub pob cemented carbide nrog ib txoj kab uas hla yog nias rau hauv qhov chaw ntawm steel kauj, thiab tus nqi hardness yog xam raws li txoj kab uas hla ntawm indentation. Qhov kev ntsuam xyuas hardness tuaj yeem ntsuas qhov kev ua tau zoo thiab hnav-tiv taus thiab lwm yam khoom ntawm cov hlau kauj. Rau qee qhov steel - coil daim ntawv thov scenarios uas yuav tsum tau machining los yog muaj siab hnav - cov kev cai tiv thaiv, hardness yog ib qho tseem ceeb zoo qhia.
