Laifin lalacewa ta hanyar da ba za a iya raba shi ba Billet, damuwa na ciki (kamar damuwa na ciki, damuwa nama) ya yi yawa da kuma fashewar bilet.
1. Decarbanization
Decarbization yana nufin cewa Carbon a farfajiya Layer na ƙarfe ne oxidized a cikin babban zazzabi, saboda rage carbons na farfajiya na farfajiya yana raguwa sosai da sabon abu.
Zurfin Layer ƙarshen Layer yana da alaƙa da abun da ke ciki, abun da ke ciki na iskar gas, zazzabi, da kuma rufin da a wannan zafin jiki. Haske yanayin oxoxiDation mai sauƙi yana da sauƙi ga Decarberization, Carbon Karfe mai sauƙi yana da sauƙi ga nasarar, silicon karfe ma yana da sauƙin ƙwallan.
Decarbangization yana rage ƙarfi da gajiya aikin sassan, kuma ya raunana sandar juriya.
2. Carbon yawan
Karkace-zantawa da fatalwar mai mai yawa sau da yawa a farfajiya ko wani bangare na farfajiya. Wasu lokuta kauri daga carbon Layer Layer ya kai 1.5 ~ 1.6mm, abun ciki na carbon na gida ya kai kashi 2% (kashi biyu), da kuma lystenite nama ya bayyana.
Wannan shine mafi yawan lokuta a cikin yanayin dumama mai zafi, lokacin da Billet yake kusa da mai bututun mai, saboda haka man da iska ba su cika da kyau ba, saboda haka man da iska ba su cika ba, saboda haka yana haifar da tasirin carbon Carbon.
Carbon ƙaru yana sa injin ya tsabtace mara kyau, kuma yana da sauƙi a yanka lokacin yankan.
3. Overheat
Overheat yana nufin yawan zafin jiki na ƙarfe Billet ya yi yawa, ko a cikin ƙayyadadden ƙayyadaddun zafin jiki, ko tashi zafin jiki ya haifar da tasirin zafin jiki.
Carbon Karfe (ƙaramin-ko akan ƙarfe na bincike) sau da yawa ya bayyana bayan an overheating. Bayan Martensitic Karfe Overheat, yakan bayyana a cikin Tsarin Crystal, kuma mold karfe galibi ana santa ta hanyar overheating nama. Bayan titanium Dayoy ya yi huhawa, bayyananne a fili gaba na lokaci kuma madaidaiciyar siriri sarkin sei ya bayyana. Bayan overheating na alloy karaya zai bayyana dutse daya ko murhu rauni. Superheated nama, saboda babban hatsi girman, zai rage kaddarorin na inji, musamman ma tasirin tasiri.
Bayan maganin zafi na yau da kullun (ƙonewa, ya faɗi), za a iya inganta ƙungiyar ƙarfe na iya inganta kuma ana mayar da aikin. Wannan overheating galibi ana kiranta rashin iya amfani da ruwa; Kuma mummunan overheating na sutthani bayan kan iyakokin zazzabi (ciki har da fitilar zazzabi), ana iya kawar da ƙwayar cuta ko cin nama ko a sauƙaƙe.
4. Da yawa yana ƙonewa
Overbururing yana nufin cewa yawan zafin jiki na ƙarfe Billet ya yi yawa ko yana kasancewa a cikin babban oxygen da sauransu, da kuma sauran haɗin oxness da iri-iri iri-iri, da kuma yin hade da haɗi tsakanin hatsi, da rage haɗi tsakanin hatsi, da rage hade da filayen. Karfe tare da mummunan ƙonewa zai crack da laushi mai laushi yayin cire fashewar, da fasahar transverse zasu bayyana a ƙona lokacin zane.
Babu wani iyakar zafin jiki mai tsauri tsakanin overburing da zafi. Gabaɗaya, Heɓaɓɓiyar Heada da kuma narkewar halayen don yin hukunci da ƙonewa. Don Carbon Karfe, lokacin da hatsi na narkewa da daskararren oxlygen mold karfe (high Speed karfe, da sauransu (Eter 12 buga ciki, da sauransu. Iyakar Crystal ta narke cikin triangle hanya kuma tunatar da ball bayyana lokacin da aluminum ado ya cika. Karkace bayan an ƙone shi, sau da yawa ba za a iya samun ceto ba, dole ne a scrade.
5. Fasa na zafi
Lokacin da dumin karot tare da manyan sittin da kuma seloyy karfe da kuma yawan zafin jiki zai yi sauri a cikin ƙarancin yanayin zafi, idan dumama zai samar da babbar damuwa mai zurfi a tsakanin ciki da waje. Bugu da kari, billet din yana da matalauta filastik saboda ƙarancin zafin jiki. Idan ƙimar damuwa ta atomatik ta wuce iyakar iyakar Billet, mai haske mai tsananin dumama za a samar da crack da ke tsakiyar zuwa yankin da ke kewaye da shi, yana sanya duka sashi crack.
6. Crisp na tagulla
Bugun tagulla na tagulla a saman gyarwar. A High kallo, haske rawaya rawaya mai launin shuɗi (ko m na silverl) ana rarraba shi tare da iyakar hatsi.
When the billet is heated, such as the residual copper oxide in the furnace, the oxide steel is reduced to free copper at high temperature, and the molten steel atoms expand along the austenite grain boundary, which weakens the connection between the grains. In addition, when the copper content in the steel is higher [>2% (Frain 100)], kamar yadda aka haɗo a cikin yanayin iskar shaye-shaye, an kafa shi a cikin fata na ƙarfe, wanda kuma ke haifar da rauni.
