Incazelo Yomkhiqizo:
Umkhiqizo usetshenziswa esithandweni esilawulekayo se-aural sokwelashwa okuhlukahlukene kokushisa, ukugwema ukuthintana komphumela ovuthayo we-elding noma ukugwema ukugqwala kwegesi yesithando somlilo ukuya endaweni yokushisisa. Inqubo (ukuguqulwa kokushiswa kwe-elding noma amandla kagesi) ifakwa eshubhuni yensimbi ephikisayo futhi ivumele inani lokushisa liphume ngodonga lweshubhu. Le divayisi ibizwa ngokuthi ishubhu yokushisa.

I-Electrothermal heater tube izovala isici sokushisa ejazini, ngemuva kokufakwa kukagesi nokushisa, ukushisa kukhishwa ngokungaqondile ku-liner yomlilo kanye ne-workpiece ezoshiswa nge-bushing. Ukushisa kweshubhu yokushisa kusetshenziswa esithandweni sokuvikela indlebe nokugqwala, njengesithando somlilo esiqhubekayo, i-roller furnace, isithando somlilo somgodi.

Izinzuzo ze-tube:
Ukulawuleka kwe-aural ngaphakathi kwesithando somlilo kungaqinisekiswa.
Ukulawula izinga lokushisa, ukuhlanganisa kanye ne-maintainace kulula kakhulu futhi kungaba lula ukuvala.
I-cubage yeziko liyakhuliswa futhi ukuphuma kuyathuthukiswa ngenxa yokuthi alikho ibhodwe le-muffle
Amandla okushisa aqinile nokusebenza kahle okuphezulu
I-refractory steel material igcina.
Izinto ze-tube:
I-electrothermal alloy material esetshenziswa yithubhu yokushisisa kufanele ibe nezinga eliphezulu lokumelana. Iphesenti lokuguqulwa kwe-galvanothermy liphezulu. Ngenxa yokuthi ishubhu lokufudumeza lifakwa esihlahleni, inqubo yokudlulisa ukushisa ihlukile kuleyo yohlobo oluvulekile lwesici sokushisa. Isivikelo sayo sokushisa sikhulu. Izinga lokushisa le-elementi kufanele lilawulwe lapho izinga lokushisa likhuphuka, ukugwema ukuhamba kwezinga lokushisa kwento.
Uma ishubhu lokushisisa livaliwe futhi lishiswa, izinga lokushisa elingaphezulu lesici sokushisa liphezulu cishe kunezinga lokushisa leziko ngo-100 C~150 C. Ngakho-ke izinga lokushisa leziko nomoya wokushisa wesithando kuyadingeka ukuze kuhlaziywe. Khetha izinto zokushisisa ezifanele.
Ishubhu yokushisa ekhiqizwa inkampani ye-gongtao ivamise ukusebenzisa i-Cr20Ni80, Cr25A15, Cr21A16Nb, Cr27A17Mo2 ect.
