APPARATUS FOR MANUFACTURING CERAMIC PIPE

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing ceramic pipes which enables the ceramic pipes to be rotated without the occurrence of rubbing flaws in firing and is low in fuel consumption. SOLUTION: This apparatus is provided with a preheating furnace 3 for preheating the molded and dried ceramic pipes P while conveying the same and a heating furnace 2 which has plural sets of forward and backward pipe rotating means 22 consisting of a pair of forward rotating and backward rotating ceramic rollers 22a and a rotary moving hearth 21 for rotationally moving plural sets of these pipe rotating means 22 around the perpendicular axial center and fires the ceramic pipes P preheated in the preheating furnace 3 while forward and backward rotating the ceramic pipes and conveying the pipes by the rotary moving hearth 21. The apparatus is provided with a cooling furnace 4 for cooling the ceramic pipes P fired by the heating furnace 2 and is provided with pipe transfer means for transferring the ceramic pipes P from the preheating furnace 3 to the heating furnace 2 and from the heating furnace 2 to the cooling furnace 4.
