Njira zopangira Ferro-tungsten ndi njira ya agglomeration, njira yochotsera chitsulo ndi njira yotentha ya aluminiyamu.

Calcium silicate cored wire (CaSi Cored Wire) ndi mtundu wa waya wokhazikika womwe umagwiritsidwa ntchito popanga zitsulo ndi kuponyera ntchito. Lapangidwa kuti liziwonetsa kuchuluka kwa calcium ndi silicon muzitsulo zosungunuka kuti zithandizire kutulutsa mpweya, kutulutsa sulphurization ndi alloying. Polimbikitsa machitidwe ovutawa, waya wa cored amawongolera khalidwe, ukhondo ndi makina azitsulo.

Vanadium ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito popanga zitsulo. Chitsulo chokhala ndi Vanadium chili ndi zinthu zabwino kwambiri monga kulimba kwambiri, kulimba kwambiri, komanso kukana kwabwino, motero chimagwiritsidwa ntchito kwambiri pamakina, magalimoto, kupanga zombo, njanji, ndege, milatho, ukadaulo wamagetsi, mafakitale achitetezo ndi mafakitale ena.

Njira zopangira mpweya wochepa komanso wapakatikati wa carbon ferromanganese makamaka umaphatikizapo njira yotenthetsera ya electrosilicon, njira ya rocker ndi njira yowombera mpweya.

Black silicon carbide imapangidwa kuchokera ku mchenga wa quartz ndi petroleum coke silica monga zida zazikulu zopangira kudzera pakutentha kwambiri kusungunula mung'anjo yotsutsa. Kulimba kwake kuli pakati pa corundum ndi diamondi, mphamvu zake zamakina ndizokwera kuposa corundum, ndipo ndizovuta komanso zakuthwa. Green silicon carbide imapangidwa kuchokera ku petroleum coke ndi silika monga zida zazikulu zopangira, zokhala ndi mchere wowonjezera ngati chowonjezera, ndikusungunulidwa pa kutentha kwakukulu mu ng'anjo yotsutsa. Kuuma kwake kuli pakati pa corundum ndi diamondi, ndipo mphamvu yake yamakina ndi yapamwamba kuposa corundum.

Ferromolybdenum ndi aloyi wa molybdenum ndi chitsulo ndipo amagwiritsidwa ntchito makamaka ngati chowonjezera cha molybdenum popanga zitsulo. Kuwonjezera molybdenum ku chitsulo kungapangitse chitsulo kukhala ndi mawonekedwe ofananira bwino, omwe angathandize kuchotsa kupsa mtima ndikuwongolera kuuma kwachitsulo. Muzitsulo zothamanga kwambiri, molybdenum imatha kusintha gawo la tungsten. Pamodzi ndi zinthu zina zopangira ma alloying, molybdenum imagwiritsidwa ntchito kwambiri popanga zitsulo zosagwira kutentha, zitsulo zosapanga dzimbiri, zitsulo zosagwira asidi ndi zitsulo zamagetsi, komanso ma alloys okhala ndi zinthu zapadera zakuthupi. Kuwonjezera molybdenum ku chitsulo choponyera kungathe kuwonjezera mphamvu zake ndi kukana kuvala. Ferromolybdenum nthawi zambiri imasungunuka ndi njira yotenthetsera yachitsulo.
