Amandla aphantsi angqongqo kunye ne-microscopic (amandla aphezulu) iimfuno zezicubu. Ulwakhiwo olusezantsi lolwakhiwo lweukuthwala intsimbiibhekiselele kwi-general loose, i-central loose kunye nokwahlula, kunye ne-microscopic (ukukhulisa okuphezulu) i-microstructure ibandakanya i-annealing microstructure yentsimbi, inethiwekhi ye-carbide, i-strip kunye ne-liquid evolution, njl. I-carbide yenethiwekhi inciphisa ukuqina kwempembelelo yentsimbi kwaye yenza ukuba isakhiwo singalingani, okulula ukukhubaza kunye nokuqhekeka ngexesha lokucima. I-Banded carbides ichaphazela i-annealed and quenched tempering microstructure kunye namandla okudinwa koqhagamshelwano. Umgangatho wesakhiwo samandla aphantsi kunye naphezulu unempembelelo enkulu ekusebenzeni kunye nobomi benkonzo yeebheringi eziqengqelekayo, ngoko ke kukho iimfuno ezingqongqo zesakhiwo samandla aphantsi kunye naphezulu ekuthwaleni imigangatho yezinto eziphathekayo.
Iimfuno ezingqongqo kakhulu zokukhubazeka komphezulu kunye neziphene zangaphakathi. Ukuthwala intsimbi, iziphene zomhlaba zibandakanya ukuqhekeka, ukufakwa kwe-slag, i-burrs, i-scarring, i-oxide yesikhumba, njl. Ezi ziphene zinempembelelo enkulu ekusebenzeni kweebheringi, ukuthwala ukusebenza kunye nobomi. Kucaciswe ngokucacileyo kwimigangatho yezinto eziphathekayo ukuba ezi ziphene azivumelekanga.
Iimfuno ezingqongqo ze-carbide inhomogeneity. Ekuthwaleni intsimbi, ukuba kukho ukusabalalisa okungalinganiyo kwe-carbide, kulula ukubangela ukungalingani kwe-microstructure kunye nobunzima kwinkqubo yonyango lokushisa. I-microstructure engalinganiyo yentsimbi inefuthe elikhulu kumandla okudinwa koqhagamshelwano. Ukongeza, ukungangqinelani kwe-carbide enzulu kukwalula ukuqhekeza iindawo ezithweleyo ngexesha lokupholisa, kwaye ukungafani kwe-carbide kuya kukhokelela ekunciphiseni ubomi bokuzala. Ngoko ke, ekuthwaleni imigangatho yezinto eziphathekayo, kukho iimfuno ezithile kwiinkcazo ezahlukeneyo zetsimbi.
Iimfuno zobunzulu bomaleko we-decarburization womphezulu ongqongqo. Kukho imimiselo engqongqo kwi-surface decarburization layer yentsimbi kwimigangatho yezinto ezithwele. Ukuba umphezulu decarburization umaleko idlula scope emiselweyo umgangatho, kwaye ayisuswanga ngokupheleleyo kwinkqubo processing phambi kokuba unyango ubushushu, kulula ukuvelisa iintanda ukucima kwinkqubo yokucima unyango ubushushu, okubangela scrap of iinxalenye.
Kumgangatho wezinto zentsimbi, kukho iimfuno ezingqongqo kwindlela yokunyibilikisa, umxholo we-oksijini, ubulukhuni be-annealing, ukwaphuka, izinto ezishiyekileyo, uvavanyo lwentlantsi, imeko yokuhanjiswa, ukumakisha njalo njalo.
