Intshayelelo
Intsimbi ibisoloko iyimfuneko kwimpucuko yabantu kangangeenkulungwane, isebenza njengesixhobo esisisiseko kulwakhiwo, ukuvelisa, kunye nobuchwepheshe. I umgangatho wentsimbi umisela ukusebenza kunye nokuqina kweemveliso ezisekelwe kwintsimbi, ezichaphazela amashishini kwihlabathi jikelele. Eli nqaku liphonononga iimpawu ezichaza umgangatho ogqwesileyo wentsimbi, ukuphonononga iimpawu zayo, amabakala, iindlela zokuvelisa, kunye nezicelo zokubonelela ngokuqonda okubanzi kwesi sinyithi esibalulekileyo.
Ukubunjwa kweMichiza kunye noBunyulu
Ukwakhiwa kweekhemikhali zentsimbi kuchaphazela kakhulu umgangatho wayo. Intsimbi ephezulu ecocekileyo iqulethe ukungcola okuncinci njengesulfure, i-phosphorus, kunye ne-non-metallic inclusions. Oku kungcola kunokunciphisa ukunyaniseka kwesakhiwo sesinyithi kwaye kuchaphazele iimpawu zayo zomatshini. Owona mgangatho wentsimbi ubalaseleyo ubonisa ukubunjwa okulinganayo kunye nezixa ezilawulwayo zekhabhoni kunye nezinto ezixutywayo ezifana nemanganese, isilicon, kunye nenickel. Ngokomzekelo, i-iron enekhabhoni ephantsi, eyaziwa ngokuba yintsimbi ekhandiweyo, inika i-ductility egqwesileyo kunye nokuqina, iyenze ilungele umsebenzi wokuhombisa kunye nezakhiwo zentsimbi ezintsonkothileyo.
Indima yoMxholo weCarbon
Isiqulatho sekhabhoni sidlala indima ebalulekileyo ekumiseleni ubulukhuni bentsimbi kunye nokomelela kwayo.
