Zinthu zomwe zimawonjezeredwa kuzitsulo zodula mwaulere zikuphatikizapo S, Pb, Ca ndi P. Ntchito zawo zazikulu ndi izi:
1. Ntchito ya sulfure
Sulfure imapanga MnS inclusions ndi Mn muzitsulo, zomwe zingasokoneze kupitiriza kwa matrix, kupanga tchipisi kukhala kosavuta kusweka, ndi kuchepetsa malo okhudzana pakati pa chips ndi chida. Sulfure imathanso kuchepetsa mikangano ndikuletsa tchipisi kuti zisamamatire kumapeto. Komabe, kukhalapo kwa sulfure kungapangitse chitsulo kukhala chotentha komanso chophwanyika, kotero kuti sulfure nthawi zambiri imakhala yochepa pa w(s)=0.10%~0.30%, ndipo zomwe zili mu Mn ziyenera kuwonjezeredwa moyenerera kuti zigwirizane nazo.
2. Udindo wa mtsogoleri
Kuphatikizika kwa Pb kumatha kusintha magwiridwe antchito achitsulo. Popeza Pb samasungunuka mu ferrite muzitsulo ndipo samapanga mankhwala, imakhala mumkhalidwe waulere ndipo imapanga tinthu tating'onoting'ono (2 ~ 3μm) zomwe zimagawidwa mofanana mu dongosolo la matrix. Kutentha komwe kumapangidwa panthawi yodula kumafika posungunuka particles za Pb, zimakhala zosungunuka ndipo zimakhala "lubricant" pakati pa chida ndi tchipisi ndi pakati pa chida ndi workpiece pamwamba, kuchepetsa mikangano, kutentha kwa chida, ndi mavalidwe. Kuchuluka kwa Pb kuwonjezeredwa kuli mu w(Pb)=0.1%~0.35%.
3. Udindo wa calcium
Ca ikhoza kupanga Ca ndi Al silicate inclusions muzitsulo, zomwe zimamatira ku chida chopangira filimu yopyapyala, kukhala ndi zotsatira zochepetsera mikangano, ndikuletsa kuvala kwa zida. Kuchuluka kwa Ca kuwonjezeredwa nthawi zambiri ndi w(Ca)=0.001%~0.005%.
4. Udindo wa phosphorous
P amawonjezedwa ku chitsulo chokhala ndi sulfure chodula mwaulere kuti chisungunuke mu ferrite, kuchititsa kulimbitsa ndi kusungunula kupititsa patsogolo ntchito yake yodula. Pofuna kupewa "kuzizira kozizira", w(P) amatchulidwa kuti ≤0.15%.
Kuwonjezera kwa zinthuzi kungathenso kupititsa patsogolo khalidwe lapamwamba la workpiece ndikuwonjezera moyo wautumiki wa chidacho.

Ngati mukufuna zambiri zatsatanetsatane, tikulimbikitsidwa kuti mutifunse kuti mumve zambiri zatsatanetsatane komanso ntchito zazitsulo zazitsulo za alloy.

FAQ

Q: Kodi opanga ua?

A: Inde, ndife opanga. Tili ndi fakitale yathu yomwe ili ku Daqiuzhuang Village, Tianjin City, China. Kupatula apo, timagwirizana ndi mabizinesi ambiri aboma, monga BAOSTEEL, SHOUGANG GROUP, SHAGANG GROUP, etc.

Q: Kodi ndingakhale ndi oda yoyeserera matani angapo okha?

A: Zoonadi. Titha kukutumizirani katunduyo ndi LCL serivece.(Kuchepa kwa chidebe)

Q: Kodi muli ndi malipiro apamwamba?

A: Kwa dongosolo lalikulu, masiku 30-90 L / C akhoza kuvomerezedwa.

Q: Ngati chitsanzo chaulere?

A: Zitsanzo zaulere, koma wogula amalipira katundu.

Q: Kodi ndinu ogulitsa golide ndipo mumatsimikizira zamalonda?
