Ts'ebetso ea graphitization ea iron ea cast le lintlha tse amang graphitization ea iron ea cast

 1. Ts'ebetso ea graphitization ea tšepe ea tšepe

    Ts'ebetso ea graphite ka tšepe ea tšepe e bitsoa ts'ebetso ea graphitization. Ts'ebetso ea mantlha ea sebopeho sa tšepe ea tšepe ke ts'ebetso ea graphite ka tšepe ea tšepe. Ka hona, ho bohlokoa haholo ho utloisisa maemo le lintlha tse susumetsang tsa ts'ebetso ea graphitization ho tseba sebopeho le thepa ea lisebelisoa tsa tšepe.

    Ho latela setšoantšo se habeli sa mmuso sa alloy ea Fe-C, ts'ebetso ea graphitization ea tšepe e ka aroloa ka mekhahlelo e meraro:

    Mokhahlelo oa pele ke karolo ea mokelikeli oa hypoeutectic crystallization. Ho kenyelletsa khanya e hlakileng ea "graphite" ea mantlha e tsoang karolong ea mokelikeli ea likarolo tsa hypereutectic le karolo ea mokelikeli ea likarolo tsa eutectic ho hlakisa austenite plus graphite, graphite e entsoeng ka ho bola cementite ea mantlha le cementite ea eutectic nakong ea mocheso o phahameng

    Sethala se mahareng ke sethala lipakeng tsa phetoho ea eutectic le phetoho ea hypoeutectoid. Ho kenyelletsa pula e tobileng ea graphite ea bobeli e tsoang ho austenite le graphite e entsoeng ke ho bola ha samente ea sekhahla maemong ana a mocheso.

    Mokhahlelo oa boraro, ke hore, karolo ea phetoho ea theolelo eohle. Ho kenyelletsa graphite ea eutectoid e entsoeng nakong ea phetoho e kopaneng le graphite e entsoeng ke ho bola ha samente ea eutectoid nakong ea ho annealing.

2. Lintho tse amang graphitization ea iron iron

    Sebopeho sa tšepe e entsoe ho latela boholo ba graphitization. Bakeng sa ho fumana sebopeho se hlokahalang, senotlolo ke ho laola boemo ba graphitization. Ts'ebetso e netefalitse hore lintlha tse ngata tse kang lik'hemik'hale tsa tšepe e entsoeng ka tšepe, sekhahla se pholileng sa likristale tsa tšepe, ho chesa le ho ema ha tšepe e qhibilihisitsoeng, jj. Kaofela li ama graphitization le microstructure ea iron e entsoeng.

1. Tšusumetso ea sebopeho sa lik'hemik'hale

    Har'a tse tloaelehileng tsa C, Si, Mn, P, le S ka tšepe ea tšepe, C le Si ke likarolo tse khothalletsang graphitization ka matla, 'me S ke ntho e sitisang graphitization ka matla. Ebile, tšusumetso ea karolo e ngoe le e ngoe ho bokhoni ba graphitization ea tšepe ea tšepe e thata haholo. Tšusumetso ea eona e amana le litaba tsa karolo ka 'ngoe ka bo eona le hore na e sebelisana le likarolo tse ling, joalo ka Ti, Zr, B, Ce, Mg, jj. Kaofela li sitisa graphitization, empa haeba litaba tsa eona li le tlase haholo (joalo ka B, Ce <0.01%, T <0.08%), li bonts'a litlamorao tsa ho khothaletsa graphitization.

2. Phello ea sekhahla se pholileng

    Ka kakaretso, sekhahla se pholileng sa li-castings se lula se le butle haholo, ha se le molemo haholo bakeng sa kristale le phetoho ho latela setšoantšo sa mmuso sa sistimi e tsitsitseng ea Fe-G, le graphitization e felletseng; ho fapana le hoo, ho molemo bakeng sa kristale le phetoho ho latela setšoantšo sa mmuso sa Fe-Fe3C sistimi e fetolehang. Qetellong a fumana tšepe e tšoeu. Haholo-holo ho graphitization sethaleng sa eutectoid, kaha mocheso o tlase, sekhahla sa ho futhumatsa sea eketseha, 'me phallo ea liathomo e thata, ka kakaretso ho thata ho ntšetsa pele graphitization sethaleng sa eutectoid.

    Sekhahla se futhumatsang sa tšepe ea tšepe ke ntlha e pharalletseng, e amanang le mocheso o tšollang, ho khanna hoa thepa ea letsopa le botenya ba lebota. Mme hangata lintlha tsena li na le tšusumetso e tšoanang methating e 'meli.

    Ho eketsa mocheso o tšollang ho ka liehisa sekhahla se pholileng sa ho betsa, se khothalletsang mohato oa pele oa graphitization le mohato oa bobeli oa graphitization. Ka hona, ho eketsa mocheso o tšollang ho ka silafatsa graphite ho isa bohōleng bo itseng, hape ho ka eketsa phetoho ea eutectoid.

3. Phello ea ho chesa haholo le ho ema ha mocheso o phahameng oa tšepe

    Nakong ea mocheso o itseng, ho eketsa mocheso o chesang haholo oa tšepe e qhibilihisitsoeng le ho eketsa nako ea mocheso o phahameng ho tla fella ka ntlafatso ea sebopeho se entsoeng ka graphite ka tšepe ea tšepe le ho eketsa matla a tšepe ea tšepe. Haeba superheat e eketsoa ka ho eketsehileng, bokhoni ba nucleation ea tšepe ea tšepe bo tla fokotseha, 'me graphite morphology e tla senyeha, mme le samenteite ea mahala e tla hlaha, e tla fokotsa matla, ka hona ho na le' mocheso o matla '. Mocheso o mahlonoko haholo-holo o ipapisitse le lik'hemik'hale tsa tšepe e qhibilihisitsoeng le sekhahla sa ho futhumatsa ha ho betsa. Ka kakaretso ho lumeloa hore mocheso o mahlonoko oa tšepe e tloaelehileng ea bohlooho e ka ba 1500-1550 ℃, ka hona ho lula ho ts'epuoa hore mocheso oa tšepe o phahame.

Ka kopo boloka mohloli le aterese ea sengoloa sena hore se hatisoe hape: Ts'ebetso ea graphitization ea iron ea cast le lintlha tse amang graphitization ea iron ea cast
