Dab tsi yog 1018 txias dov hlau?
1018 steel yog qis- carbon steel hauv SAE / AISI kev faib tawm nrog cov ntsiab lus carbon txog li 0.18%. Nws belongs rau "10" series, uas qhia tau hais tias cov pa roj carbon zoo tib yam. Qhov "18" qhia txog cov ntsiab lus carbon ntawm 0.18%. Txias dov yog txheej txheem uas cov hlau ua tiav raws li qhov yuav tsum tau ua thiab cov duab ntawm chav tsev kub uas siv lub tshuab dov lossis tshuab kos duab. Txias-rolled steel muaj zog dua thiab hardness, ib tug du nto thiab siab precision{11}} txias-rolled steel yog haum rau cov khoom uas yuav tsum tau siab precision thiab zoo nkauj, xws li shafts, zog thiab tshuab qhov chaw.
Cov txheej txheem khoom
- Pib nrog kub- dov steel, uas feem ntau yog dov saum toj no qhov kub ntawm recrystallization.
- Pickling tshem tawm cov nplai thiab ua kom lub ntsej muag huv.
- Txias dov lossis kos duab txias: Cov khoom siv tau ua tiav ntawm chav tsev kub hauv lub tshuab dov lossis lub tshuab nqus tsev rau qhov xav tau tuab lossis loj. Txias dov yog siv rau daim ntawv thiab strips, thiab kos duab txias rau tuav.
- Annealing tej zaum yuav ua tau los txo hardness thiab txhim kho ductility, los yog kev nyuaj siab relieving kom txo tau cov residual kev nyuaj siab.
Cov txheej txheem txias dov nce lub zog thiab hardness, tab sis tuaj yeem qhia txog kev ntxhov siab sab hauv. Seb los yog tsis yuav anneal nyob ntawm daim ntawv thov.
Qhov zoo thiab qhov tsis zoo ntawm 1018 txias dov hlau
Qhov zoo:
- Qhov saum npoo yog du thiab muaj qhov siab qhov tseeb, haum rau kev tsim khoom ntawm precision qhov chaw.
- Nws muaj cov machinability zoo heev thiab tsim nyog rau kev xa thiab drilling.
- Cov txheej txheem txias dov nce lub zog thiab hardness, ua rau nws haum rau cov ntawv thov uas xav tau lub zog siab.
- Lub hardness saum npoo tuaj yeem nce ntxiv los ntawm carburizing, txuas ntxiv rau qhov kev siv.
Qhov tsis zoo:
- Cov nqi siab dua li kub - dov steel, thiab nws yuav tsis haum rau cov ntawv loj - cov qauv siv.
- Nws cov ductility qis dua qhov kub ntawm -khoov hlau, thiab kev ntxhov siab yuav tsum tau ua kom tsis txhob tawg thaum lub sijhawm khoov hnyav.
- Nws cov kev tiv thaiv corrosion yog nruab nrab, thiab nws yooj yim rau xeb thaum raug cov av noo lossis ntsev tsuag ib puag ncig. Nws yuav tsum tau pleev xim los yog galvanizing rau kev tiv thaiv.
Cov kev tshawb fawb tau pom tias nws tsis txaus corrosion kuj yog qhov txwv tsis pub siv sab nraum zoov thiab yuav tsum tau saib xyuas tshwj xeeb.
Kev sib piv nrog lwm cov hlau
Piv rau 1018 kub- dov steel: qhov txias -rolled version muaj zog (tensile zog 440 MPa vs . 440-530 MPa rau kub- dov, tab sis siab dua yield zog), muaj ib tug smoother nto thiab zoo dua qhov tseeb, tab sis yog kim dua.
Piv rau 1020 steel: 1020 muaj cov pa roj carbon ntau dua me ntsis (0.18-0.23%) thiab muaj zog me ntsis, tab sis nws yog me ntsis formable.
Piv rau A36 kub- dov steel: A36 qis zog (yield zog 250 MPa), tab sis nws yog pheej yig dua thiab haum rau kev siv cov qauv siv.

Kev xaiv tswv yim
Xaiv raws li qhov xav tau ntawm qhov project:
- Yog hais tias siab precision thiab nto tiav lawm, xaiv 1018 txias-rolled steel, haum rau shafts, zog thiab precision qhov chaw.
- Yog tias xav tau lub zog siab dua, xav txog nruab nrab carbon steel xws li 1045.
- Rau kev siv sab nraum zoov, pleev xim lossis galvanizing yog pom zoo los txhim kho corrosion.
- Ua ntej txiav txim siab zaum kawg, nws raug nquahu kom sab laj tus neeg muag khoom rau cov ntaub ntawv ua haujlwm tshwj xeeb thiab cov lus qhia tshwj xeeb.
