Chisonkhezero cha zinthu zisanu za chitsulo chotsitsa

Kupanga kwamankhwala kwa chitsulo cha Dutile kumaphatikizapo kaboni, silicon, manganese, sulufule, phosphorous zinthu zofala zinthu. Kwa kupanduka kwina ndi zofunikira zapadera zamagulu ndi magwiridwe, kuphatikizapo magawo ochepa a Aloy. Chosiyana ndi imvi wamba, kuti tiwonetsetse zojambula za graphite, chivundikiro cha Dutile ayeneranso kukhala ndi ndalama zotsalazo zotsalira.
1. Mfundo yosankhidwa yosankha kaboni ndi kaboni chimodzimodzi: kaboni ndiye chitsulo choyambirira, komanso kaboni kwambiri ndi yofunika kwambiri. Chifukwa kukopa kwa graphite pa makina ocheperako achepetsedwa pamlingo wotsika kwambiri, ma carbon omwe ali ndi chitsulo nthawi zambiri amakhala okwera, pakati pa 3.5%, ndi 4.7%. Tengani malire kumtunda kwa khoma loonda, lotsalira lalikulu lazinthu zopumira kapena kuperewera kosakwanira; khalani ndi malire. Kusankha kaboni Kutalika pafupi ndi Cocrystal mfundo sikungakuthandizeninso kungodzilimbitsa thupi, komanso kusintha luso la chitsulo, komanso kusintha luso la chitsulo, komanso kusintha kuthekera kwa chitsulo, chifukwa chofuna kuchita zachitsulo chifukwa cha kuchuluka kwa zolimba. Komabe, zomwe zili m'misika yayitali zimatha kuchititsa galasi kuyandama. Chifukwa chake, malire apamwamba a kaboni ofanana ndi chitsulo cha Dutile amatengera mfundo ya palibe choyandama cha graphite.
2, Mfundo yosankhidwa ya silicon: silicon ndi chinthu cholimba. Mu chitsulo cha Dutile, silika sichingachepetse chizolowezi choyera ndikuwonjezera kuchuluka kwa chiphunzitso cha Ferrite, komansonso mphamvu yakuyeretsa gulu la cocrystal ndikuwongolera kuchuluka kwa malo ojambula zithunzi. Komabe, silicon imawongolera kutentha kwa britletch yosinthanso chitsulo (Chithunzi 1) Kuti muchepetse kulimba mtima, makamaka pomwe zomwe zakhala ndikukhala ndi chitsulo chokwera kwambiri, ndizofunikira kwambiri kuwongolera zomwe zili mu Sicon. Kuchuluka kwa siyicnon yomaliza mu chitsulo cha ductile nthawi zambiri 1.4- -3.0%. Pambuyo posankha kaboni chimodzimodzi, mfundo ya mphamvu yayikulu ya kaboni ndi yotsika ya silicon nthawi zambiri imakhazikitsidwa. Malire otsika a silicon amatengera mfundo yopanda thupi laulere.
3. Mfundo zosankhira ku Mangaese: Kuyambira pa sulufule chitsulo chotsika kwambiri, palibe chifukwa cha Manganese kwambiri kuti agwirizane ndi chisoti champhamvu chimakhala chikuwonekera bwino. Carbide iyi imayang'aniridwa pamalire a tirigu ndipo imathandizira kwambiri pakulimba kwa chitsulo. Manganese adzachulukitsa kutentha kwa Brittle kwa Ferrite Deracle Chitsulo, kuchuluka kwa 0,1% pofika 10 mpaka 12 digiri. Chifukwa chake, zomwe zimachitika mu chitsulo cha Ductile nthawi zambiri zimatsika, ngakhale chitsulo chopepuka cha bead ductor ductile, zokhala ndi manganese siziyenera kupitirira 0,4 ~ 0.6%. Malalanje okhaokha okha ndi a Ferrite pa cholinga chotha kusintha.
4. Mfundo Zosankhidwa za phosphorous: phosphorous ndi chinthu choyipa. Ili ndi kusungunuka kochepa kwambiri mu chitsulo, pomwe zomwe zili ndi zosakwana 0.05%, kusungunuka kolimba mu matrix, osagwira ntchito pamakina. Zomwe zili zokulirapo kuposa 0,05%, phosphorous ndizosavuta kusiyanitsa m'malire a gulu la kristalo, oyenda kapena ma phosphorous co-grosil stanch. Phosphorous imawonjezera kutentha kwa brittle kusinthitsa chitsulo, ndikuwonjezera mawu a phosphorous pofika 4 mpaka 4.5 digiri. Chifukwa chake, kutsitsidwa kwa zomwe zili mu phosphorous mu chitsulo chodyera, chabwino, nthawi zambiri chimayenera kukhala chosakwana 0.08%. Kuti mupeze zotumphukira kwambiri, zomwe zilipo za phosphorous ziyenera kukhala zosakwana 0,05%.
