Abstract
In a pass-through sintering furnace for sintering a succession of ceramic tubes fed lengthwise through the furnace and rotated as they pass through the furnace, the tubes, when heated in the furnace, are kept apart by pushing each tube into the furnace at one end and pulling it out from the other end. The pulling speed is less than the pushing speed to ensure uniform firing throughout the length of the tube, allowing for shrinkage as the tube is fired, but is sufficient to hold the pulled tube clear of the next following tube so as to obviate any pushing against the end of a hot tube.
