Indlela yokukhetha isiseko sokubumba?

Iisiseko sokungundayinkxaso yokungunda. Umzekelo, kumatshini wokuphosa ukufa, iindawo zokubumba ziyadityaniswa kwaye zilungiswe ngokwemigaqo ethile kunye nezikhundla, kwaye inxalenye eyenza ukuba i-mold ifakwe kumatshini wokuphosa ubizwa ngokubaisiseko sokungunda. Yenziwe ngepedi yokufa kunye nepleyiti yokuhlala. Xa usebenzisa isiseko sokubumba esichanekileyo, kufuneka sisebenze kakuhle ukwenzela ukuqinisekisa ukuba yonke i-mold inomsebenzi omhle kakhulu kwisicelo. Ngoko ke, xa uthenga olu hloboisiseko sokungunda, kufuneka uzame konke okusemandleni akho ukukhetha Phakathi kwabo, isiseko sokungunda esinemisebenzi efanelekileyo kakhulu siluncedo kakhulu kwisicelo somntu wonke.

Ukuchanekaisiseko sokungundaigcina umlinganiselo omncinci wentsalela ye-austenite kwaye inokuphumza uxinzelelo njengoko kufuneka, esebenza njengesithinteli. Ngenxa yokuba i-austenite eshiyekileyo ithambile kwaye yomelele, inokufunxa ngokuyinxenye amandla okwanda okukhawulezayo kwe-martensitize kwaye inciphise uxinzelelo lotshintsho; yikhuphe emva konyango olubandayo Ukubeka iisiseko sokungundaemanzini ashushu ukufudumala kunokuphelisa i-40% -60% yoxinzelelo lonyango olubandayo. Emva kokufudumala kwiqondo lokushisa kwegumbi, kufuneka lihlanjululwe ngexesha lokuphelisa ngakumbi uxinzelelo lonyango olubandayo, ugweme ukubunjwa kweentanda zonyango ezibandayo, ufumane iimpawu ezizinzileyo zezicubu, kwaye uqinisekise ukuba iimveliso zesiseko sokubumba zigcinwa kwaye zisetyenziswe. Akukho kugqwethwa kwenzekayo.
