Ukusebenziseka Kwamandla Welding Welding Consumables Ukwakhiwa

Ukuqondiswa kokusebenza kahle kwesakhiwo se-weld sensimbi enamandla amakhulu ukukhiqiza i-ferrite eyengeziwe. Ucwaningo lukhombisile ukuthi i-acicular ferrite inosayizi omuhle wokusanhlamvu kanye nokuqina okuphezulu kokuhlukaniswa. Lapho okuqukethwe kwayo kukhulu kuno-65% futhi ubukhulu be-lath bucishe bube yi-1 μm, insimbi ye-weld ingaba namandla amakhulu nobulukhuni.

Ungayithola kanjani le nhlangano engenhla?

Idizayini efanelekile yokwakheka kwensimbi yokwakha ingukhiye.

1. C. Okuqukethwe C ngokuvamile kulawulwa ku-0.05% kuye ku-0.10%, kanti okulingana nekhabhoni kungaphansi kuka-0.39. Kulolu hlu, kungenziwa i-side slat ferrite ne-acicular ferrite, futhi indawo evuselelayo ye-weld iguqulwa ibe yi-equiaxed ferrite enkulu.
2. Mnu. UMn unemiphumela emibili ephikisanayo ekucwengweni kwensimbi nasekuqiniseni. Okuqukethwe okulungile kwe-Mn kungathola i-ferrite engaphezulu. Kodwa-ke, ukwengezwa ngokweqile kwe-Mn kuzobangela ukuthi isilinganiso semingcele ye-bainite ye-bainite sibe ngaphezulu kune-intragranular nucleation rate ye-acicular ferrite, ezokwandisa ubulukhuni be-weld. Okuqukethwe kwe-Mn ngokuvamile kulawulwa ku-0.6 kuya ku-1.8%.
3. Cr. Njengoba okuqukethwe kwe-Cr kusimbi yensimbi kukhuphuka, inani le-acicular ferrite liyakhula, ukwakheka kwe-weld kuyacwengisiswa, ne-proeutectoid ferrite esendaweni enezindawo eziyikholamu nendawo ecezwana kakhulu iyancipha. Ubulukhuni bomthelela buyancipha ngokwanda kokuqukethwe kwe-Cu futhi kukhuphuke ngokwanda kokuqukethwe kwe-Cr. Okuqukethwe kwe-Cr ngokuvamile kungu-0.9 kuye ku-1.0%.
4. Ti. Ibanga lokuqukethwe le-Ti lokuthola inhlanganisela ephelele yesakhiwo nokusebenza komthelela kungu-0.02% kuye ku-0.05%. Ucwaningo lukhombisile ukuthi lapho okuqukethwe kwe-Ti kusimbi ye-weld kungu-0.014% kuya ku-0.048%, isakhiwo se-weld sepuleti le-Q235 sakhiwe kakhulu nge-equiaxed ferrite ne-acicular ferrite. Ngokwanda kokuqukethwe kwe-Ti, i-acicular ferrite Ukwanda kokuqukethwe nokwehla kobude kuzokhulisa ukuqina kwensimbi ye-weld. Lokhu kungenxa yokwakhiwa kwe-TiO2 inclusions lapho okuqukethwe kwe-Ti kusimbi yensimbi kuphakeme kunokuqukethwe kwe-Al, okuhambisana ne-nucleation ye-acicular ferrite.
5. B. Ukuhlolwa kukhombisa ukuthi lapho okuqukethwe kwe-B kuphakathi kuka-0.0032% no-0.0103%, i-acicular ferrite iyancipha ngokwanda kokuqukethwe kwe-B, namandla omthelela ancishiswe kakhulu. Lokhu kungenxa yokwehla kwezinga lokushisa le-eutectoid elidalwe nguB. Kodwa-ke, uma kufakwa iTi ephakeme ocingweni lwe-welding futhi i-alkalinity ephansi iqinisekiswa, futhi lapho isilinganiso se-boron ne-nitrogen (B / N) ku-weld metal u-0.6 kuye ku-0.8, ukwakheka kwezinaliti kungasiza. I-ferrite nucleated Ti-equkethe i-oxide inclusions ingathola inani eliphakeme lokuqina kwensimbi ye-weld; uma i-B / N ingaphezulu kuka-0.8, ubunzima bethonya luzokwehla. Okuqukethwe kwe-B kuvame ukulawulwa ngaphakathi kwe-0.003 ～ 0.006%.
6. U-O. O uyisici sokungcoliswa esivimbelayo ensimbi ye-weld. I-Al, Mg namanye ama-ejenti wokunciphisa anamandla avame ukungezwa ensimbi ye-weld ukwenza i-deoxidize nokulungisa i-nitrogen, kepha kulula ukwenza i-polygonal AlN inclusions inclusions, eyonakalisa kakhulu ubunzima obuphansi bokushisa kwensimbi ye-weld. Kuphakanyiswa emibhalweni ukuthi ukufaka inani elifanele le-LiF kumgogodla we-flux kuzokhiqiza i-Li3N nge-N endaweni ye-arc, ngaleyo ndlela kunciphise kakhulu okuqukethwe kwe-N kwinsimbi yensimbi futhi kunciphise inani lokufakwa kwe-AlN okuyingozi. Kukhona nombono wokuthi ukwakheka kwesigaba se-V (C, N) ngemvula ye-N ne-V kungakhuthaza i-nucleation ye-acicular ferrite. Kubuye kuvezwe ezincwadini ukuthi ukwengezwa kwamanani afanele we-Fe2O3, MnO2, njll. Kumongo kungakhuphula okuqukethwe kwe-O kwinsimbi yensimbi, kepha kwakha ukufakwa okuyindilinga okubuswa yi-Al2O3, okusalungele ukuthola i-acicular ferrite . Inhlangano ye-Weld. Ngokuvamile kukholelwa ukuthi ngaphakathi komkhawulo we-Al / O = 0.45, ukwanda okufanelekile kwe-Al / O isilinganiso esiphansi sensimbi yensimbi yensimbi kungakhuthaza ukukhiqizwa kokufakwa okuningi ngosayizi we-0.2 kuye ku-0.8 μm, kukhuthaze i-nucleation ye-ferrite ye-acicular, ngakho-ke ukuqina kuyathandeka.
7. I-S.S futhi iyinto yokungcola enomkhawulo kunsimbi eyinsimbi, kepha izinhlayiya ze-FeS eziqukethe inani elincane le-Mn ne-Cu zisebenza ku-nucleation ye-acicular ferrite.

Ngaphezu kwalokho, ukulawulwa kobukhulu nokuma kokufakwa nakho kubaluleke kakhulu. Ngokuvamile kukholakala ukuthi izinhlayiya eziyindilinga ikakhulukazi ezakhiwe yi-MnS nezinye izigaba ze-amorphous ezinosayizi we-0.5-0.8 μm kanye noqweqwe oluncane lwe-TiO ebusweni lusiza kakhulu i-acicular ferrite nucleation.
