Ingcaciso yeMveliso:
Le mveliso isetyenziswa kwi-oven elawulwayo yonyango lobushushu eyahlukeneyo, ukuthintela ukudibana kwesiphumo sokutsha kwe-elding okanye ukuthintela ukugqwala kwegesi ye-oven ibe yinto yokufudumeza. Inkqubo (ukuguqulwa kokutsha kwe-elding okanye amandla ombane) ifakwa kwityhubhu yentsimbi enganyangekiyo kwaye ivumela ubungakanani bobushushu bukhanye ngodonga lwetyhubhu. Esi sixhobo sibizwa ngokuba yityhubhu ye-heater.

Ityhubhu yeheater ye-electrothermal iya kuyivala into yokufudumeza ekwijakethi, emva kokufaka umbane nobushushu, ubushushu budluliselwa ngokungathanga ngqo kwi-liner ye-furnace kunye ne-workpiece ukuze bufudunyezwe nge-bushing. Ubushushu betyhubhu yeheater busetyenziswa kwi-furnace kunye nokukhusela i-aural kunye ne-corrodent aural, njenge-furnace eqhubekayo, i-roller furnace, i-pit furnace.

Iingenelo zetyhubhu:
Ukulawulwa kwesithando somlilo ngaphakathi kwesandi kunokuqinisekiswa.
Ulawulo lobushushu, ukuhlanganiswa kunye nokugcinwa kwezinto kulula kakhulu kwaye kulula ukulivala.
I-cubage yeziko iyandiswa kwaye amandla okukhupha aphucukile ngenxa yokungabikho kwembiza yokuthula
Amandla okufudumeza aqinileyo kunye nokusebenza kakuhle okuphezulu
Izinto zentsimbi ezichaseneyo zigcinwa.
Izinto ezisetyenziswa kwityhubhu:
Izinto ze-electrothermal alloy ezisetyenziswa yityhubhu yokufudumeza kufuneka zibe nesantya esiphezulu sokuxhathisa. Ukuguqulwa kwepesenti ye-galvanothermy kuphezulu. Ngenxa yokuba ityhubhu yokufudumeza ifakwa kwi-bushing, inkqubo yokudlulisela ubushushu yahlukile kweyesixhobo sokufudumeza esivulekileyo. Isikhuselo sayo sobushushu sikhulu. Ubushushu besixhobo kufuneka bulawulwe ngexesha lokunyuka kobushushu, ukuze kuthintelwe ukunyuka kobushushu besixhobo.
Xa ityhubhu yeheater ivaliwe kwaye ishushu, ubushushu bomphezulu wento yokufudumeza buphezulu kakhulu kunobushushu bomlilo nge-100 C ~ 150 C. Ngoko ke ubushushu bomlilo kunye nomoya wobushushu bomlilo ziyafuneka ukuze kuhlalutywe. Khetha izinto zokufudumeza ezichanekileyo.
Ityhubhu yeheater eveliswa yinkampani yegongtao idla ngokusebenzisa iCr20Ni80, Cr25A15, Cr21A16Nb, Cr27A17Mo2 njl.
