GUCURUZA
Ingano za LF1 na LF2 byaba byiza zikozwe ku bushyuhe buri hagati ya 2250-2300ºF (1230-1260ºC) kandi ntibishoboka byakozwe munsi ya 1650-1700ºF (900-925ºC.) Itsinda Ubwoko bwa LF3 bwaba bukozwe ku bushyuhe buri hagati ya 2150-2200ºF (1175-1205ºC) kandi ntibishobokabyakozwe munsi y'ubushyuhe bwa 1700ºF (925ºC.)
UBUVUZI/UBUSHYUHE
Nta gushidikanya ko gutunganya ubushyuhe bw'ibyuma by'imiyoboro bizakorwa buri gihe nyuma yo gusudira. Imiterere y'ibyo byuma izabanza kugenwa n'uburyo bwo kuzingurura/gucura. Umuyoboro ubwawo uzatangwa n'ibyuma bishyushye, ibyuma bifunganye n'ibindi bivuye mu byuma bifunganye. Uburyo nyabwo bwo gusudira buzaba ingenzi mu kwemeza ko umuyoboro ukwiriye kandi ufite umutekano n'imikorere yawo nyuma yo kuwusukura. Gushyushya no gusukura nyuma yo gushyushya ni ingenzi.
Amanota atatu yavuzwe hano ashobora gusukurwa byoroshye n'uburyo bwose bwageragejwe kandi bwageragejwe.
UBUSHOBOZI BW'AMASHINI
Ku bijyanye n'ibikoresho by'ubukorikori n'ibice by'ubukorikori, ibi byiciro gishoboragukorerwa imashini uko bikenewe, kandi uburambe buhoraho buzagena niba gutunganya ari byiza gukorwa ku nyubako ikozwe nk'iy'ubukorikori, inyubako isanzwe cyangwa inyubako ifunze. Uko biri kose, bitewe n'imiterere y'ingenzi y'ikoreshwa rya nyuma, inama zigomba gutangwa n'ikigo cyemewe gishinzwe gutunganya ubushyuhe..
