I-VIM vacuum induction ncibilikisa isithando somlilo esinesistimu yokushisisa yokonga amandla

I-Vacuum Induction Melting (VIM) ukuncibilika kwensimbi ngokungeniswa kwe-electromagnetic ngaphansi kwevacuum.Isithando somlilo esifakiwe esiqukethe i-refractory line crucible ezungezwe ikhoyili yokungeniswa sitholakala ngaphakathi kwegumbi le-vacuum.Isithando somlilo esingeniswayo siwumthombo wamandla oxhunywe imvamisa ehlobana ngokunembile nosayizi wesithando somlilo nezinto ezincibilikiswayo.

Okubalulekile kushajwa esithandweni sokungeniswa ngaphansi kwevacuum futhi amandla asetshenziswa ukuncibilikisa inkokhiso.Izindleko ezengeziwe zenziwa ukuletha umthamo wensimbi owuketshezi kumthamo ofunekayo wokuncibilika.Insimbi encibilikisiwe icwengwa ngaphansi kwe-vacuum futhi ikhemistri ilungiswa kuze kube yilapho kutholakala ikhemistri encibilikayo enembile.Ukungcola kususwa ukusabela kwamakhemikhali, ukuhlukaniswa, ukuntanta kanye nokuguquguquka.Lapho ikhemistri encibilikayo oyifunayo ifinyelelwa, i-tundish eshisiwe ifakwa nge-valve ehlukanisiwe yokhiye wokufaka i-tundish eshisayo.Le tundish ephikisayo ibekwe phambi kwesithando somlilo sokungeniswa futhi insimbi encibilikisiwe ithululelwa nge-tundish, ekubunjweni okulindile.

I-VIM inqubo esetshenziselwa ukwenza ama-superalloys, izinsimbi ezingagqwali, ama-alloys kazibuthe namabhethri, ama-alloys kagesi, namanye ama-alloys yenani eliphakeme adinga kakhulu.
