Abstract
A rotary centrifugal quartz melting furnace comprises a rotary furnace body, a feeding system, a heating element and an automatic control system. The heating element is arranged in the center of the rotary furnace body, high-temperature-resistant insulating end covers are arranged at two ends of the rotary furnace body, electrode inserting holes are arranged in centers of the insulating end covers, movable electrode stands are arranged on two sides of the rotary furnace body, electrodes are arranged on the electrode stands, and two ends of the heating element are connected with the electrodes. Materials are ejected towards the inside of the rotating furnace by a feeding gun, materials injected into the furnace form a 'cylindrical' quartz material ring owing to the action of centrifugal force generated when the furnace body rotates at a high speed, and the heating element is inserted into the charged 'cylindrical' quartz material ring of the furnace rotating at the high speed to electrically melt the 'cylindrical' quartz material ring. Melted quartz forms a consistent, smooth and compact 'cylindrical' quartz block along the inner wall of the furnace body under the action of the centrifugal force, so that the maximum utilization rate can reach 80% in the aspect of deep processing for special quartz products such as thick-walled tubes, conical tubes, quartz rings and plates. Besides, the precision of the special quartz products can be improved, and the processing time can be shortened.
