Wrought hlau yog ib hom kev lag luam hlau muaj tsawg dua 0.10% ntawm carbon , tsawg dua 0.25% ntawm impurities tag nrho cov sulfur, phosphorus, silicon thiab manganese, thiab tsawg dua 2% slag los ntawm qhov hnyav. Wrought hlau yog redshort los yog kub luv yog hais tias nws muaj sulfur ntau ntau.
Yog li ntawd, cov ntsiab lus carbon ntawm wrought hlau yog dab tsi?
Wrought hlau yog ib hom kev lag luam hlau muaj tsawg dua 0.10% ntawm carbon , tsawg dua 0.25% ntawm impurities tag nrho cov sulfur, phosphorus, silicon thiab manganese, thiab tsawg dua 2% slag los ntawm qhov hnyav. Wrought hlau yog redshort los yog kub luv yog hais tias nws muaj sulfur hauv ntau dhau.
Qhov thib ob, qhov feem pua ntawm carbon nyob rau hauv cam khwb cia hlau yog dab tsi? Feem ntau cam khwb cia hlau muaj cov tshuaj muaj pes tsawg leeg ntawm 2.5-4.0% carbon 1-3% silicon, thiab lwm yam hlau.
Tom qab ntawd, ib tus tuaj yeem nug, qhov feem pua ntawm cov pa roj carbon hauv npua hlau yog dab tsi?
3.5 - 4.5%
Qhov twg los ntawm cov hlau muaj qhov siab tshaj plaws ntawm cov pa roj carbon?
Cam khwb cia hlau nrog 4.2% carbon yog carbon ntau ua tau, vim 4.2% yog solubility txwv rau carbon hauv hlau.

Yuav ua li cas yog qhov tsawg kawg nkaus pob zeb npog nyob rau hauv mm ntawm ib tug cam khwb cia nyob rau hauv qhov chaw pob zeb tso tawm tsam thiab mus tas li raug rau lub ntiaj teb?
Table-1: Yam Tsawg Npog Thickness rau Cast-in-Place Qhob Hom kev tsim ua vaj tse hla, hli Qhob nrum tiv thaiv thiab txuas mus tas li nrog hauv av 75 Pob zeb sib chwv nrog av lossis dej No. 19 txog No. 57 tuav 50 No. 16 bar thiab me dua 40
Dab tsi txaus ntshai zoo kawg li nws yog qhov peb yuav tsum tau khawb trenches thiab sim cov roj npog qhov ncauj qhov ntswg ntawm no vim muaj kev sib cav nyob hauv lub tebchaws nyob deb ntawm cov neeg uas peb tsis paub dab tsi?
Qhov txaus ntshai npaum li cas, zoo heev, zoo kawg yog tias peb yuav tsum tau khawb trenches thiab sim roj-qhov ncauj qhov ntswg ntawm no vim muaj kev sib cav nyob rau hauv ib lub teb chaws nyob deb ntawm cov neeg uas peb tsis paub dab tsi. Nws zoo nkaus li tseem tsis yooj yim dua tias kev sib cav uas twb tau hais tseg hauv txoj cai yuav tsum yog kev ua tsov rog
Nyob rau hauv cov nroj tsuag twg photosynthesis tshwm sim nyob rau hauv qia es tsis nyob rau hauv nplooj?
1 Teb. Nyob rau hauv cov nroj tsuag photosynthesis tshwm sim nyob rau hauv chloroplasts. Chloroplast tuaj yeem nyob hauv lub hlwb ntawm cov txiv hmab txiv ntoo, stems, tab sis feem ntau ntawm tag nrho cov nplooj. Hauv qee qhov succulents (xws li cacti), lub ntsiab photosynthetic kev ua haujlwm yog txuam nrog lub qia
