Cov txheej txheem los daws cov teeb meem suav nrog

* Kev txiav txim tsis raug:

Muaj qhov pom tseeb qhov chaw, thaiv thiab sawb tsis xws luag nyob rau saum npoo ntawm steel phaj.Tom qab annealing, nws yuav pom tseeb dawb los yog dub.Nyob rau hauv cov xwm txheej hnyav, deg tev tawm, qhov tsis xws luag thiab tsis sib xws concave-convex defects yuav tshwm sim.Nws yog ib qho yooj yim los txiav txim qhov suav nrog tev, tab sis nws yog ib qho yooj yim kom tsis meej pem rau qhov kev txiav txim ntawm me ntsis nto stripe inclusion thiab nto khawb.Kev txiav txim siab qhov sib txawv tseem ceeb no yog qhov kev raug mob Ge yog qhov tsis tu ncua, zoo ib yam, qhov dav yog nqaim heev;Strip suav nrog tsis tu ncua, tsis sib xws, dav dav.Los yog los ntawm kev sib tsoo nto, khawb qhov tob yuav tsis sib sib zog nqus, kev sib tsoo tuaj yeem raug tshem tawm, thiab suav nrog qhov sib sib zog nqus, tom qab sib tsoo nto, yuav muaj qhov tob ntxiv.

 

 

* Kev soj ntsuam ua rau:

Kev suav nrog yog tshwm sim los ntawm cov hlau tsis muaj hlau nyob hauv cov txheej txheem nruam casting, uas pib muaj nyob rau hauv daim tawv nqaij ntawm daim tawv nqaij, thiab raug rau saum npoo tom qab kub dov thiab txias dov.Vim muaj cov roj thiab oxidation thiab lwm yam impurities nyob rau saum npoo ntawm dov tawv phaj, cov inclusions tsis pom tseeb, thiab tuaj yeem qhia meej meej tom qab annealing.

* Txoj kev kho mob:

1) Npaj cov qauv, thaij duab thiab sau lawv, thiab sau cov lus pom zoo rau cov txheej txheem kawg hauv ib qho kev taw qhia

2) Tshem tawm qhov pom muaj qhov tsis xws luag ua ntej cov txheej txheem annealing tiav lawm

3) Tom qab annealing, pom me me tsis xws luag yuav tsum degraded los ntawm kev kho thiab kho muaj nuj nqi
