Kev sib piv ntawm cov ntawv kub dov thiab txias dov daim ntawv txheej txheem

Nyob rau hauv cov txheej txheem ntawm cov hlau, kub dov thiab txias dov yog ob qho tseem ceeb heev txheej txheem. Lawv muaj kev cuam tshuam loj rau lub koom haum thiab cov khoom ntawm cov hlau. Lub hom phiaj ntawm tsab xov xwm no yog txhawm rau tshawb nrhiav qhov sib txawv ntawm ob txheej txheem, los pab cov neeg nyeem kom nkag siab zoo dua lawv cov ntawv thov thiab cov yam ntxwv.

 

Ua ntej, cov txheej txheem kub dov

 

Kub dov, raws li lub npe qhia, yog txheej txheem dov uas cov hlau tau rhuab mus rau qhov kub thiab txias. Feem ntau, lub ingot los yog billet yuav rhuab mus rau 1100 degree ~ 1250 degree kub ntau yam, ua raws li los ntawm dov nyob rau hauv lub zeb. Qhov ntsuas kub ntawm qhov kub dov feem ntau yog tswj ntawm 800 degree txog 900 degree, tom qab ntawd cov hlau yog txias lawm hauv huab cua.

 

Qhov saum npoo ntawm cov hlau kub kub yuav tsim ib txheej ntawm cov hlau oxide, uas tsis tsuas yog muab cov hlau ib qho kev tiv thaiv corrosion, yog li nws tuaj yeem khaws cia hauv huab cua qhib, tab sis kuj ua rau lub ntsej muag rougher thiab loj dua qhov hloov pauv. Yog li ntawd, rau qhov chaw tiav thiab qhov tseeb qhov yuav tsum tau muaj ntawm cov hlau siab, feem ntau yog nyob rau hauv cov khoom kub dov semi-tiav los yog cov khoom tiav raws li cov txheej txheem txias dov.

 

Qhov zoo ntawm kev kub dov muaj xws li kev sib sau ceev ceev, siab yields, thiab muaj peev xwm tsim tau ntau yam ntawm cov ntawv hla ntu ntawm cov hlau tsis muaj kev puas tsuaj rau txheej. Tsis tas li ntawd, kub dov kuj tseem tuaj yeem ua rau cov txiaj ntsig zoo ntawm cov hlau, txhim kho nws cov khoom siv kho tshuab.

 

Thib ob, txheej txheem txias dov

Tsis zoo li kub dov, txias dov yog txheej txheem hlau dov ntawm chav tsev kub. Txawm hais tias cov hlau phaj yuav sov so thaum lub sij hawm ua, tab sis tag nrho qhov kub thiab txias tseem nyob rau hauv qis qis. Txias dov feem ntau yog ua nrog kub dov steel coils raws li cov khoom siv raw, tom qab pickling kom tshem tawm cov tawv nqaij oxidized, kev ua haujlwm siab hauv cov dov zeb, thiab thaum kawg tau dov tawv coils.

Cold dov steel muaj qhov ua tiav ntawm qhov siab thiab qhov kev xav zoo, uas feem ntau yog vim cov txheej txheem pickling. Nyob rau tib lub sij hawm, lub zog thiab hardness ntawm txias dov hlau kuj kuj siab, zoo plasticity thiab elongation, yog li nws yog dav siv nyob rau hauv tsheb, khoom siv hauv tsev thiab kho vajtse industries.

Lub ntsiab kom zoo dua ntawm txias dov yog tias nws tuaj yeem rhuav tshem lub koom haum casting ntawm lub ingot, ua kom cov nplej ntawm cov hlau, thiab tshem tawm qhov tsis xws luag ntawm microstructure, yog li txhim kho cov khoom siv ntawm cov hlau. Tsis tas li ntawd, txias dov kuj tuaj yeem ua rau qee qhov kev tshem tawm ntawm kev tsim cov npuas, tawg thiab xoob thiab lwm yam tsis xws luag.

 

Thib peb, qhov sib txawv ntawm qhov kub dov thiab txias dov

1. qhov sib txawv ntawm qhov kub thiab txias: kub dov ntawm qhov kub thiab txias, thaum txias dov yog ua tiav ntawm chav tsev kub. Qhov no yog qhov sib txawv tseem ceeb tshaj plaws ntawm ob txoj kev.

2. nto zoo: txias dov daim ntawv nto tiav yog siab, thaum lub kub dov hlau yog kuj ntxhib.

3. Cov yam ntxwv ntawm kev ua tau zoo: qhov taw tes tawm ntawm cov ntawv kub dov yog siab dua, tab sis lub zog thiab hardness ntawm txias dov hlau yog siab dua. Tsis tas li ntawd, txoj kev tsim cov khoom ntawm cov kuav los tiag txias kuj zoo dua rau cov kub dov hlau.

Zuag qhia tag nrho, kub dov thiab txias dov muaj lawv tus kheej cov yam ntxwv thiab qhov zoo, qhov kev xaiv ntawm cov txheej txheem yog nyob ntawm cov kev xav tau tshwj xeeb ntawm daim ntawv thov thiab kev ua haujlwm ntawm cov hlau. Los ntawm kev nkag siab txog qhov sib txawv thiab cov yam ntxwv ntawm ob txoj haujlwm no, peb tuaj yeem xaiv cov hlau zoo rau qhov project.
