Uma kuqhathaniswa nezitini ezivamile ezimelana nokushisa, izitini zokuvimbela ukufudumala ezilula zilula ngesisindo, ama-pores amancane asatshalaliswa ngokulinganayo ngaphakathi, futhi ane-porosity ephezulu. Ngakho-ke, kungaqinisekisa ukuthi ukushisa okuncane kuzolahleka odongeni lwesithando, futhi izindleko zikaphethiloli ziyancishiswa ngokufanele. Izitini ezilula nazo zinesitoreji esincane sokushisa, ngakho kokubili ukushisa nokupholisa kwesithando esakhiwe ngezitini ezilula kuyashesha, okuvumela izikhathi zomjikelezo ezisheshayo zesithando. Izitini zokuvimbela ukufudumala ezilula ezimelana nokushisa zifanelekela izinga lokushisa elingu-900 ℃ ~ 1650 ℃.
Izici zeisitini sokushisa esilula
1. Ukushisa okuphansi, amandla okushisa aphansi, okuqukethwe okungcolile okuphansi
2. Amandla aphezulu, ukumelana okuhle nokushaqeka kokushisa, ukumelana okuhle nokugqwala emoyeni we-asidi ne-alkali
3. Ukunemba kobukhulu obuphezulu
Ukusetshenziswa kwezitini zokuvimbela ukukhanya okulula
1. Izinto ezahlukahlukene zokufakelwa kwe-hot surface lining, njenge: i-annealing furnace, i-carbonization furnace, i-tempering furnace, i-oil refinering heating furnace, i-cracking furnace, i-roller furnace, i-tunnel furnace, njll.
2. Izinto zokuvikela ezisekelayo zezitofu zezimboni ezahlukahlukene.
3. Ukunciphisa isithando somlilo.
