Me yasa graphite zai iya maye gurbin jan ƙarfe a matsayin lantarki?

Ta yaya graphite zai iya maye gurbin jan ƙarfe a matsayin lantarki?Babban ƙarfin injina Graphite Electrode China.

A shekarun 1960, an yi amfani da jan ƙarfe sosai a matsayin kayan lantarki, inda yawan amfani ya kai kusan kashi 90%, yayin da graphite kuma ya kai kusan kashi 10% kawai. A ƙarni na 21, masu amfani da yawa sun fara zaɓar graphite a matsayin kayan lantarki. A Turai, fiye da kashi 90% na kayan lantarki graphite ne. Tagulla, wanda a da yake shine babban kayan lantarki, ya kusan rasa gefensa fiye da graphite. Me ya haifar da wannan babban canji? Tabbas, akwai fa'idodi da yawa na lantarki graphite.

(1) saurin sarrafawa mai sauri: gabaɗaya, saurin sarrafawa na inji naGraphite electrode na sayarwazai iya zama sau 2-5 da sauri fiye da na jan ƙarfe; Duk da haka, edm ɗin ya fi jan ƙarfe sau 2-3 da sauri, kuma kayan ba su da saurin lalacewa. Matsayin tausasa jan ƙarfe yana da kusan digiri 1000, kuma yana da sauƙin lalacewa ta hanyar zafi. Zafin graphite sublimation na digiri 3650; Matsakaicin faɗaɗa zafi shine 1/30 kawai na jan ƙarfe.

(2) nauyi mai sauƙi: yawan graphite shine 1/5 kawai na jan ƙarfe, wanda zai iya rage nauyin kayan aikin injin (EDM) yadda ya kamata lokacin da aka sarrafa manyan electrodes ta hanyar fitarwa; Ya fi dacewa da amfani da babban mold.

(3) yawan fitar da ruwa ya yi ƙasa; Tunda man walƙiya yana ɗauke da ƙwayoyin C, yayin sarrafa fitar da ruwa, zafin jiki mai yawa yana sa ƙwayoyin C da ke cikin man walƙiya su ruɓe, wanda hakan ke samar da fim mai kariya a saman electrode na graphite, wanda hakan ke rama asarar electrode na graphite.

(4) babu burrs; Bayan an sarrafa na'urar jan ƙarfe, yana buƙatar a gyara shi da hannu don cire burrs, yayin da ake sarrafa graphite ta hanyarMasana'antar lantarki ta Graphiteba tare da burrs ba, wanda ke adana kuɗi mai yawa kuma yana sauƙaƙa samar da kayan aiki ta atomatik

(5) graphite ya fi sauƙin niƙawa da gogewa; Tunda graphite yana da kashi ɗaya bisa biyar kawai na juriyar yankewa na jan ƙarfe, yana da sauƙin niƙawa da gogewa da hannu.

(6) ƙarancin farashi da farashi mai ɗorewa; Saboda hauhawar farashin jan ƙarfe a cikin 'yan shekarun nan, farashin isotropic graphite ya yi ƙasa da na jan ƙarfe. A ƙarƙashin wannan adadin, farashin samfuran graphite na toyo carbon ya yi ƙasa da kashi 30% ~ 60% fiye da na jan ƙarfe, kuma farashin ya fi ɗorewa, canjin farashi na ɗan gajeren lokaci ƙanƙanta ne.

Saboda wannan fa'idar da ba ta misaltuwa, graphite ya maye gurbin jan ƙarfe a hankali a matsayin kayan da aka fi so don na'urar lantarki ta EDM.
