Dab tsi yog tus tiv thaiv ntawm Rimmed hlau thiab laum hlau tawg?

Raws li lub degree ntawm deoxidization thaum lub sij hawm smelting, lub hlau yuav muab faib ua rimmed hlau, semi-tua hlau, tua hlau thiab tshwj xeeb tua steel. Rimmed hlau yog ib yam hlau uas muaj cov pa carbon dioxide nrog cov deoxidis tsawg heev. Cov pa no ua rau cov pa roj carbon dioxide ua rau cov pa roj carbon dioxide ua rau cov pa roj carbon dioxide thaum cov pa roj carbon dioxide (carbonated) ua rau cov pa roj carbon monoxide (carbonated).

 

Txoj hlua hlau tawg yog lub hlau uas yog deoxidized tag nrho, lub ntsiab lus uas cov ntsiab lus oxygen tsis ntau tshaj 0.01% (feem ntau ntawm 0.002% thiab 0.003%). Cov hlau uas tsis muaj hlau tsis rhaub thaum lub sij hawm casting thiab lawv feem ntau raug muab pov rau hauv cov pob kws nrog cov tsho loj thiab me me. Vim tias muaj lub hau khwb khiab rau saum toj ntawm lub pob zeb (kom ntxiv cov hlau uas muaj hlau thaum solidified steel yog solidified), lub taub hau cap yuav tsum tau muab tshem tawm tom qab dov thiab qoob loo, yog li qhov qis tus nqi ntawm cov hlau ua qis thiab tsis zoo txawm yog, tab sis yuav tsim cov qauv kev cog lus thiab kev cais me me. High quality hlau thiab hlau alloy yog feem ntau tua steel.

 

Kev sib txawv ntawm qhov sib txawv:

Qhov kev kawm ntawm cov raug tua steel yog zoo dua li ntawm cov cua ntawm cov cua. Raug tua cov hlau muaj feem ntau siv los ua kom muaj kev sib haum xeeb los ntawm cov hlau phom sij uas yuav tsum muaj kev ua haujlwm siab, thaum cov tswv yim dav hlau xws li cov vaj tsev zoo tib yam yog cov rimmed los yog cov cua tawg.

 

Daim Ntawv Thov Tawm Tsam:

Txwv los ntawm nws tus kheej cov yam ntxwv, cov roj thiab silicon cov ntsiab lus ntawm rimmed hlau yog tus tsawg. Tom qab muab dov mus rau hauv nyias daim hlau, nws muaj qhov zoo txaus ntom nti thiab kev ua tau zoo heev hauv yas, qhov vuam, kev kub thiab txias. Nws yog dav siv nyob rau hauv steel rau tsheb laij teb tsheb, tsheb dashboards thiab rechargeable roj teeb. Tab sis kuj muaj ntau impurities, muaj pes tsawg leeg segregation loj dua, tsis sib luag thiab lwm yam kev poob haujlwm.

 

Nqe Teebmeem:

Rimmed steels sib txawv los ntawm cov hlau tua pov tseg nyob rau hauv qhov nyiaj deoxidising tus neeg saib xyuas ntxiv yog tsawg dua. Muaj cov qhov loj loj hauv qhov tua cov hlau, uas ua rau nws cov qoob loo ntau dua li ntawm cov cua ntawm qhov rimmed, yog li tus nqi ntawm cov hlau tua raug ntau dua li ntawm cov pob hau.
