Isihloko: Ukuqonda ukubaluleka kokunyibilikisa i-Metal Alloys kwi-aI-Vacuum Induction yokunyibilikisa i-Furnace

Inkqubo yokunyibilikisa idlala indima ebalulekileyo xa kuveliswa iintsimbi ezikumgangatho ophezulu. Ukunyibilika kubandakanya ukukhupha isinyithi kwi-ores kunye nokudala i-alloys ngokudibanisa izinto ezahlukeneyo zetsimbi. Enye yeendlela eziphambili zokunyibilikisa i-alloys yesinyithi kukusetyenziswa kwe-vacuum induction melting (VIM) . Le teknoloji entsha ibonelela ngeenzuzo ezininzi, iyenza ibe sisixhobo esibalulekileyo sokuvelisa i-alloys zetsimbi ezahlukeneyo.

Ngoko ke, zeziphi iintlobo zeentsimbi zensimbi ezifuna ukunyibilika kwi-aivacuum induction yokunyibilikisa iziko? Ukuphendula lo mbuzo, kubalulekile ukuqonda iimpawu ezikhethekileyo zesithando somlilo se-VIM kunye neemfuno ezithile zee-alloys zetsimbi ezahlukeneyo.

Okokuqala, kubalulekile ukuqaphela ukubaluleka kokusebenza kwindawo ye-vacuum xa kunyibilika ii-alloys ezithile zetsimbi. Ukugcina igumbi le-vacuum lingenawo umoya kunye nokunye ukungcola kubalulekile ukukhusela i-oxidation kunye nokungcoliswa ngexesha lenkqubo yokunyibilikisa. Oku kubaluleke ngakumbi kwii-alloys ezisebenza kakhulu okanye ezithanda ukwakheka kweoksidi xa zisemoyeni.

Olunye uhlobo lwealloyi yesinyithi oluxhamlayo ekunyibilikisweni kwi-vacuum induction melting furnace yi-alloys yobushushu obuphezulu. Ezi zixhobo zihambele phambili ziyaziwa ngamandla azo akhethekileyo, ukuxhathisa kwi-corrosion kunye nokusebenza okuphezulu kobushushu, nto leyo ezenza zibe yimfuneko kumashishini afana ne-aerospace, ukuveliswa kwamandla kunye nokulungiswa kweekhemikhali. I-alloys ephezulu yokushisa ihlala iqulethe i-nickel, i-cobalt, isinyithi kunye nezinye izinto, kwaye ukuveliswa kwazo kufuna ukulawulwa ngokuchanekileyo kwenkqubo yokunyibilika ukuze kuqinisekiswe ukuba izinto eziphathekayo ezifunwayo ziyafezekiswa. Ngokusebenzisa isithando somlilo se-VIM, abavelisi banokususa ngokufanelekileyo ukungcola kunye nokugcina ingqibelelo ye-alloy, okubangelwa kwiipropati eziphezulu zoomatshini kunye ne-thermal.

Ukongeza kwi-alloys yobushushu obuphezulu, ezinye iintsimbi ezikhethekileyo zikwafuna ukusetyenziswa kwe-vacuum induction melting furnaces ukwenzela ukunyibilikisa. Ngokomzekelo, insimbi engenasici iyaziwa ngokuchasa ukubola kunye nokungcolisa, okwenza kube yinto ekhethiweyo yokhetho kwizicelo zokutya kunye nokusela, amashishini amayeza kunye neekhemikhali. Ukunyibilikisa intsimbi engatyiwayo kwindawo efunxayo kunceda ukunciphisa ubukho bobumdaka obunobungozi obufana nesalfure kunye nephosphorus, ezinokubeka esichengeni ukuxhathisa kokutya. Ngenxa yoko, isinyithi esigqityiweyo esingenasici sinokucoceka okuphezulu kunye nokusebenza, ukuhlangabezana neemfuno ezingqongqo zezicelo ezahlukeneyo zoshishino.

Ukongezelela, i-aerospace kunye necandelo lokukhusela lixhomekeke kwimveliso ye-titanium alloys, enika amandla abalaseleyo okulinganisa amandla kunye nokumelana nokugqwesa okubalaseleyo. Ukunyibilika kwealloyi zetitanium kwiziko lokunyibilikisa elifunxayo kubalulekile ekufezekiseni ubunyulu obuphezulu kunye nokufana okufunekayo kumalungu asemajukujukwini afana neenjini zenqwelomoya kunye nezakhiwo. Ukukwazi ukulawula ukubunjwa kunye ne-microstructure ye-titanium alloys ngokusebenzisa iteknoloji ye-VIM iqinisekisa ukuba imveliso yokugqibela idibana nokusebenza okungqongqo kunye nemigangatho yokuthembeka kwiindawo ezifunwayo ze-aerospace.

Ukongeza kule mizekelo ethile, ezinye ii-alloys zetsimbi ezininzi, ezibandakanya izixhobo zentsimbi, i-steel-speed-speed, kunye ne-alloys magnetic, zinokuzuza ngokuchaneka kunye nokucoceka okubonelelwa nge-vacuum induction melting melting. Ukukwazi ukulungelelanisa inkqubo yokunyibilika kwiimfuno ezizodwa ze-alloy nganye ivumela abavelisi ukuba bahlale bevelisa izinto ezinomatshini ofunekayo, i-thermal kunye ne-chemical properties ukuhlangabezana neemfuno ezahlukeneyo zamashishini ahlukeneyo.

Isishwankathelo, i-alloys yensimbi enyibilikayo kwi-vacuum induction melting furnaces ibalulekile ekufezekiseni amanqanaba aphezulu okucoceka, ukufana kunye nokulawula okufunekayo kwizinto eziphambili. Nokuba zizii-superalloys zokusetyenziswa kobushushu obugqithisileyo, intsimbi engenastainless yezixhobo ezikwaziyo ukumelana nomhlwa, okanye ialloys yetitanium ye-aerospace kunye neenkqubo zokhuselo, amandla obuchwepheshe beVIM adlala indima ebalulekileyo ekufezekiseni iimfuno ezingqongqo kushishino lwanamhlanje. Ngokuqonda ukubaluleka kokunyibilika kwindawo ye-vacuum kunye neemfuno ezithile zee-alloys zetsimbi ezahlukeneyo, abavelisi banokusebenzisa ngokupheleleyo amandla e-VIM furnaces ukuvelisa izinto eziphezulu eziqhuba izinto ezintsha kunye nokuqhubela phambili kwiinkalo ezahlukeneyo.
