Monga mtundu wotchuka padziko lonse wa low sulfure calcined,graphitized carburizing wothandizirandi kuchepetsa wothandizila mankhwala mankhwala, timayesetsa kulenga mtengo oposa 3000 zitsulo mphero, foundries ndi zomera mankhwala m'mayiko 65 padziko lonse.

Choyamba, mphero zitsulo, mu smelting ndondomeko zitsulo ndi zitsulo mankhwala, chifukwa smelting nthawi, kugwira nthawi, kutenthedwa nthawi ndi zinthu zina, kusungunuka imfa ya carbon zinthu mu madzi chitsulo kumawonjezera, chifukwa mu carbon zili mu madzi chitsulo sangathe. kufika pamtengo woyengedwa woyenga.Pakusungunula, gawo lina la carburizer limayikidwa mu cholinga chachikulu ndikuwonjezera kaboni muchitsulo chosungunuka, kuti asungunuke chitsulo choyenera.

Awiri, makampani oponyera, carburizing wothandizira omwe amagwiritsidwa ntchito poponya, amatha kuwonjezera kuchuluka kwa zitsulo zotsalira, kuchepetsa kuchuluka kwa chitsulo cha nkhumba, ndipo wothandizila wa carburizing ali ndi cholinga chopaka mafuta, amatha kusintha bwino moyo wautumiki woponya, kuwongolera pang'onopang'ono.

Pankhani ya uinjiniya wamankhwala, mawonekedwe akuthupi ndi mankhwala a othandizira ochepetsera amafunika kukhala olondola.Mpweya monga chochepetsera amatenga nawo mbali pakuchitapo kanthu.Pansi pa kutentha kwapamwamba kwambiri, chomangira chamankhwala cha oxide chimasweka, ndipo kaboni ngati chochepetsera ndi oxidized, ndipo valence imawonjezeka.

Zinayi, zida zina zowonjezera zimakhalanso zothandiza ku carburizing agent, monga ma brake pad okhala ndi zowonjezera, monga zida zolimbana.
