APPLICATIONS:

Ya dace da walda na bakin ciki na simintin walda na simintin ƙarfe da saman injina, kamar kawunan silinda, tubalan injunan simintin ƙarfe mai launin toka mai mahimmanci, akwatunan kaya, da Kayan aikin injin da sauri.

HALAYE:

TQZ308ne mai tsarki nickel waldi core, karfi da rage graphite irin shafi baƙin ƙarfe sanda.Ana iya amfani da shi a cikin AC da DC dual manufa kuma yana da sauƙin aiki.Lokacin walda, ba lallai ba ne don waldawa don preheat.Yana da kyau tsaga juriya da kuma aiwatarwa.

GABATARWA:

1. Kafin waldawa, da lantarki bukatar da za a gasa for 1 hour tare da zafin jiki na 150 ± 10 ℃ kafin amfani.
2 Yana iya kawar da damuwa na walda kuma guje wa tsagewa ta hanyar guduma da ɗinkin walda.
3. Domin rage ƙazanta abubuwa a cikin tushe karfe shigar weld, kunkuntar farin band nisa, inganta tsaga juriya da sarrafa Properties, ya kamata a yi amfani da kananan halin yanzu waldi a Cast baƙin ƙarfe sanyi waldi.

Gyara murdiya walda:

Don gyara nakasawa a cikin yanayi mai zafi, gyaran injina da guduma an hana su sosai a cikin kewayon zafin jiki mai shuɗi (300 ℃ ~ 500 ℃) don guje wa fashewa.

Kula da waɗannan buƙatun lokacin da harshen wuta ke zafi a gida

Ba shi da kyau a sake maimaita dumama a bangare guda don kauce wa canje-canje a cikin tsarin metallographic da kayan aikin injiniya na karfe.

Kada ku haifar da maimaita gyare-gyare na tashin hankali da matsawa a bangare ɗaya.

Don ɓangarorin welded masu tauri, shayarwa da saurin sanyaya an hana su sosai.

Ya kamata a gyara sassan walda waɗanda ke buƙatar gogewa kafin a cire su don kawar da damuwa na ciki yayin cirewa.Lokacin da ake cirewa, sassan da aka naɗe dole ne a sanya su a hankali don kada su sake lalacewa.

The harshen wuta mike dumama zafin jiki na iya zama 700 ℃ ~ 850 ℃ (fuchsia), kuma kada ya wuce 900 ℃ (m ja) ga low gami tsarin karfe.
