Non-metallic inclusions ntawm steel

Taw qhia:

Non-metallic inclusions yog ib hom impurity feem ntau pom nyob rau hauv steel. Lawv tuaj yeem los ntawm ntau qhov chaw xws li cov khoom siv raw siv hauv kev tsim khoom, cov khoom paug hauv lub qhov cub, lossis cov tshuaj tiv thaiv thaum lub sijhawm tsim khoom. Lub xub ntiag ntawm non-metallic inclusions tuaj yeem muaj kev cuam tshuam loj rau kev ua haujlwm ntawm cov hlau.

Kev cuam tshuam ntawm Non-Metallic Inclusions:

Lub xub ntiag ntawm non-metallic inclusions tuaj yeem cuam tshuam tsis zoo rau lub cev thiab lub zog ntawm cov hlau. Lawv tuaj yeem txo qhov ductility, toughness, thiab lub zog ntawm cov khoom, uas ua rau muaj peev xwm ua tsis tiav thaum siv. Non-metallic inclusions kuj tuaj yeem ua rau muaj kev cuam tshuam ntawm cov hlau rau corrosion, uas tuaj yeem ua rau nws cov qauv kev ncaj ncees ntxiv.

Classification ntawm Non-Metallic Inclusions:

Non-metallic inclusions tuaj yeem muab faib ua ntau theem raws li lawv qhov loj thiab cov duab. Cov txheej txheem kev faib tawm feem ntau yog ASTM E45, uas faib cov khoom tsis yog xim hlau sib xyaw ua tsib theem, xws li A txog E. Kev suav nrog qib A yog qhov tsawg tshaj plaws thiab tsis zoo, thaum qib E suav nrog yog qhov loj tshaj plaws thiab muaj kev puas tsuaj loj tshaj plaws. Nws yog ib qho tseem ceeb los saib xyuas thiab tswj cov qib ntawm cov khoom tsis yog xim hlau suav nrog hauv kev tsim cov hlau kom ntseeg tau tias qhov kev xav tau zoo thiab cov qauv kev ua haujlwm tau ua tiav.
