Application of Far Infrared Heating Technology in Oven to Dry Unfired Pottery and Sand Core

To dry the unfired pottery with far infrared radiation can result in such advantages as speedy temperature rise, high heating efficiency, large amount of energy-saving and high quality. Some analyses are done in this paper of the oven design and calculation, circulation of heating wind and temperature control to make a suggestion that the casting in dustry attach importance to the application of the far infrared radiation heating technology.
