Cr12MoV bir wareeg ah oo kulul oo duuban

Birta Cr12MoV waxay leedahay adkeysi aad u sareysa, iyo kuwa leh qeybta iskutallaabta ee 300 ilaa 400 mm ama ka yar si buuxda ayaa loo demi karaa
Waxay ilaalin kartaa adkaanta wanaagsan waxayna xirtaa iska caabin ah 300 ℃ 400 ℃, adaygeeda ayaa ka sarreeya birta Cr12, isbeddelka mugga ayaa ah mid aad u yar inta lagu jiro deminta. Waxaa loo isticmaali karaa in lagu soo saaro noocyo kala duwan iyo qalabyo leh qaybo waaweyn oo isku dhafan, qaabab adag, iyo u adkeysiga culeysyada waaweyn ee saameynta leh. Tusaale ahaan, feedhku waxa uu ku dhintaa qaabab kakan, gelinta dhinta kakan, birta sawirka qoto dheer ayaa dhinta, sawirida siligga ayaa dhimata, saxan silig dunsan, bakhti qaboojiye ayaa dhinta, maqas goynta qabow, miinshaar wareeg ah, qalabka caadiga ah, qalabka wax lagu cabbiro, iwm.
Birta Cr12MoV waa kaarboon-sare, bir lysic-molybdenum-sare ah. Kaarboonka ku jira aad ayuu uga hooseeyaa kan birta Crl2, waxaana lagu daraa molybdenum iyo walxo vanadium, taas oo si weyn u wanaajisa habaynta kulaylka birta, saamaynta adkaanta iyo qaybinta carbide. Birtu waxay leedahay iska caabin heersare ah oo xidhasho ah, adkaansho, adkeysi, adkaansho, xasilooni kulayl, xoog cadaadis, iyo sidoo kale qallafsanaanta yar yar, wax qabad dhamaystiran oo heersare ah iyo laqabsi ballaaran. Heerkulka jilcinta kulaylku waa 520 ℃. Cabbirka goynta ayaa ka hooseeya 4mm oo si buuxda ayaa loo adkeyn karaa. Iska caabbinta xirashada birtan ayaa 3 ~ 4 jeer ka sarreysa tan qalabka birta ee xoogga yar, mugga deminta waa yar yahay. Moolka adag: saliidda deminta 200 ~ 300mm.
Inta lagu jiro habka crystallization, tiro badan oo ah carbides cad eutectic ah ayaa la sameeyay (jajabka walaxda carbonized waa qiyaastii 20%, iyo heerkulka eutectic waa qiyaastii 1150 ° C). Carbides-yadani waa kuwo aad u adag oo jilicsan. Inkasta oo kaarbiidyadu ay u jajaban yihiin heer go'an ka dib marka la rogo billet, kaarbides-yada waxaa loo qaybiyaa guntiyo, dhejisyo, baloogyo, iyo tuunsyo ay la socdaan jihada duubista, iyo heerka kala soocida ayaa kordheysa dhexroorka birta.

Codsiga

Shaqada qabowgu waxay dhintaa birta, adkaanta birta, deminta, iyo adkaysiga xanaaqa, xidho caabbinta, xooggu wuu ka sarreeyaa Cr12. Loo isticmaalo soo saarista noocyo kala duwan oo dhinta hargabka lagu dhejiyo iyo qalab leh qaybo waaweyn oo isgoysyada, qaabab adag iyo xaalado shaqo oo culus, sida dhinta feedhiyaha, dhinta jarista, dhinta tuubooyinka, dhinta sawir qoto dheer, miinshaar wareeg ah, qalabka caadiga ah, iyo cabbirada dunta duubista ayaa dhinta. iwm.
