Bitewe nigiciro mpuzamahanga cyamabuye yicyuma, vuba aha ibicuruzwa byavanyweho byazamutse kandi igiciro cyicyuma cyingurube cyatangiye kuzamuka. Ikindi kandi kurengera ibidukikije bigira ingaruka nziza murwego rwohejuru rwa karburizingi ntirubikwa. Noneho guta igiciro cyicyuma birashobora kuzamuka mukwezi gutaha. Dore ibisobanuro bikurikira:
1 Ingurube y'icyuma na kokiya
Muri Shandong, Shanxi, Jiangsu, Hebei, Henan no mu tundi turere nubwo ibyoherezwa mu byuma ari bito, ariko hari ababikora bake cyane mu bicuruzwa bityo kubara ntabwo ari byinshi. Kuzamuka kw'isoko ry'ibyuma, kokiya n'amabuye y'agaciro bigira ingaruka ku biciro by'icyuma byazamutse, mu cyumweru gishize icyuma cy'ingurube cyazamutseho 1% - 3%, kokiya yazamutseho 2% kandi ibarura ryaragabanutse. Impeshyi yingufu ziza, ibisabwa nigiciro cya kokiya bizakomeza kwiyongera. Ariko kubera ubushyuhe bwinshi nigihe cyigihe kiraza, ibyuma ninganda zikenera ibyuma byingurube ntabwo ari byiza, Biteganijwe ko igiciro cyiyongera cyane mugihe gito.
2 Umukozi usibanganya na carburizing
Igikombe cya fondasiyo cyavanyweho kubera ibibazo by’ibidukikije, ibigo byinshi byatangiye guhindura uburyo bwo gushonga itanura ry’amashanyarazi inshuro nyinshi, bifashishije igiciro gito kandi cyongera gukoreshwa mu byuma bishaje ndetse n’ibikoresho bya karubasi kugira ngo bibyare ibyuma cyangwa ibyuma byangiza. Igikoresho cyiza cya grafite carburizing nurufunguzo, ariko igice cyambere cyumwaka wa mbere kurinda ibidukikije byatumye inganda nyinshi zifunga kandi umukozi wa carburizing ntabikwa. Niki kirenzeho, ibiciro by'ibicuruzwa byazamutse kuburyo ibiciro byinganda byiyongereye no guta imiyoboro yicyuma & fitingi igiciro nacyo gishobora kwiyongera.
