Ferrosilicon ndi alloy yofunika kwambiri yomwe imagwiritsidwa ntchito popanga zitsulo ndi zitsulo zina. Amapangidwa ndi chitsulo ndi silicon, ndi zinthu zina zosiyanasiyana monga manganese ndi carbon. Kupanga kwa ferrosilicon kumaphatikizapo kuchepetsa quartz (silicon dioxide) ndi coke (carbon) pamaso pa chitsulo. Izi zimafuna kutentha kwambiri ndipo zimakhala ndi mphamvu zambiri, zomwe zimapangitsa kuti mitengo yamtengo wapatali ikhale yofunika kwambiri pozindikira mtengo wonse wopanga ferrosilicon.

Ferrosilicon chimagwiritsidwa ntchito mu makampani zitsulo, mafakitale foundry ndi kupanga mafakitale ena. Amadya 90% ya ferrosilicon. Pakati pa magulu osiyanasiyana a ferrosilicon, 75% ferrosilicon ndi yomwe imagwiritsidwa ntchito kwambiri. M'makampani azitsulo, pafupifupi 3-5kg 75% ferrosilicon amadyedwa pa tani iliyonse yachitsulo yopangidwa.

Titaniyamu si maginito.Izi ndichifukwa chakuti titaniyamu ili ndi mawonekedwe a kristalo opanda ma elekitironi osaphatikizidwa, omwe ndi ofunikira kuti chinthu chiwonetsere maginito. Izi zikutanthauza kuti titaniyamu sagwirizana ndi maginito ndipo imatengedwa ngati diamagnetic material.

Titaniyamu ndi Ferrotitanium

Titaniyamu palokha ndi chinthu chosinthira chitsulo chokhala ndi chitsulo chonyezimira, nthawi zambiri chotuwa chasiliva. Koma titaniyamu palokha singakhale wotsutsa

Njerwa ya Refractory ndi zida za ceramic zomwe nthawi zambiri zimagwiritsidwa ntchito m'malo otentha kwambiri chifukwa chosowa kuyaka komanso chifukwa ndi insulator yabwino yomwe imachepetsa kutaya mphamvu. Njerwa zowonongeka nthawi zambiri zimakhala ndi aluminium oxide ndi silicon dioxide. Imatchedwanso "njerwa yamoto."

Pali njira ziwiri zazikulu zopangira ma ferroalloys, imodzi ndikugwiritsa ntchito mpweya wosakanikirana ndi njira zoyenera zosungunulira, ndipo ina ndiyo kuchepetsa metallothermic ndi zitsulo zina. Njira yakale nthawi zambiri imagwirizanitsidwa ndi ntchito zamagulu, pomwe yomalizayo imagwiritsidwa ntchito makamaka poyang'ana ma alloys apamwamba kwambiri omwe nthawi zambiri amakhala ndi mpweya wochepa.
