Kiln for producing high-temperature glass

The invention provides a kiln which is uniform in temperature field and suitable for producing high-temperature glass. According to the kiln for producing high-temperature glass, a hearth bottom, a lower side wall, an upper side wall and a kiln top are combined to form a hearth; at least one total oxygen burning gun is arranged on the upper side wall and/or the kiln top, and more than one pair ofheating electrodes is arranged on the lower side wall, wherein the cross section of the hearth is round or tends to be round. According to the invention, the hearth of the kiln for producing glass isdesigned into the circular or approximately circular cavity, so that the temperature field in the kiln is more uniform, and the internal quality of the glass is better; through the reasonable arrangement of the oxygen-fuel combustion burner and the dual effects of the heating electrode, the temperature in the furnace can reach 1,400-1,700 DEG C, and the furnace is suitable for the production of high-temperature glass. 本发明提
