Abantu abaninzi bathanda ukunxiba izacholo zentsimbi ezixabisekileyo ezifana nezacholo, iintsimbi zomqala, imisesane, amacici, njl. njl. Iintsimbi eziphambili ezisetyenziswa kubucwebe yigolide neplatinam.
Inyathelo lokuqala ekwenzeni izacholo zentsimbi exabisekileyo kukunyibilikisa intsimbi exabisekileyo ngokusebenzisa aiziko elinyibilikayo.Kukho iintlobo ezininzi zeengqayi zokunyibilika kwiimarike.Siza kuhlangabezana neengxaki ezithile xa sikhetha isithando somlilo esinyibilikayo.Siyenzile'Siyazi ukuba leliphi na iziko elinyibilikayo elifaneleke ngakumbi kwiimfuno zethu zokunyibilikisa izinto zesinyithi.
Kwishishini lobucwebe, kuqhelekile ukusebenzisa iziko le-induction ukunyibilikisa isinyithi.Ke ukuba ufuna ukukhetha iiziko lokunyibilikisa, kufuneka unikele ingqalelo kwezi ngongoma zilandelayo:
Ngapha koko, ii-furnaces zokunyibilikisa ze-induction ziqhele ukusetyenziswa kumaza omoya aphakathi kunye neziko lombane eliphezulu.Ubushushu obuphezulu besithando somlilo esinyibilikayo esiphakathi ngama-2600°C. Ubushushu obuphezulu besithando somlilo esiphezulu yi-1600°C. Ngoko ke ukuba ujonge ukuthenga isitovu se-induction, kuxhomekeke kwintsimbi ofuna ukuyinyibilikisa.
Indawo yokunyibilika kwegolide yi-1064°C, indawo yokunyibilika kweplatinam yi1768°C, kwaye indawo yokunyibilika yesilivere yi-961°C. Ke ukuba unyibilikisa igolide nesilivere, kuya kufuneka usebenzise isithando somlilo esinyibilikisayo, hayi isithando somlilo esiphakathi.Ukuba ukushisa okunyibilikayo kuphezulu kakhulu, kuya kubangela utshintsho kumgangatho wentsimbi.Isinyithi esinyibilikisiweyo sinokungcoliseka.
Ngendlela, xa sikhetha isithando somlilo esinyibilikayo, kufuneka kwakhona sinikele ingqalelo kuhlobo lwe-crucible.Kukho iintlobo ezimbini ze-crucibles: i-graphite crucible kunye ne-quartz crucible.Ngokuxhomekeke kwiqondo lokushisa elinyibilikayo, i-graphite crucibles isetyenziswa kwii-furnaces eziphezulu.Kwaye i-quartz crucible yesithando somlilo esiphakathi.Iquartz imelana kakhulu nobushushu obuphezulu kunegraphite.Kufuneka kuqatshelwe ukuba isilivere ingasetyenziselwa kuphela kwi-graphite crucibles, kungekhona kwi-quartz crucibles.Ngenxa yokuba isilivere isabela kunye ne-quartz kwaye ikhusela isilivere ukuba inyibilike ngokupheleleyo, iya kuthi ibambelele kwi-crucible kwaye ibangele ilahleko ephezulu.
