Claims

[Scope of Claim for Utility Model Registration] (1) In a firing furnace of the type in which a front cylinder and a rear cylinder are connected in front and behind a furnace body with a built-in furnace core tube, and a conveyor belt is passed between them, A mechanism is installed to blow atmospheric gas onto the workpiece from the ceiling and sides, while suction pipes are installed in the inlet and outlet areas of the furnace core tube to exhaust the atmosphere inside the furnace to the outside of the furnace. A rectifying atmosphere blowing mechanism is installed horizontally between the opening at the end and the opening of the furnace core tube to blow out the atmospheric gas toward the opening and downward, and the inner bottoms of the furnace core tube, front cylinder, and rear cylinder are made of ceramic. A conveyor-type kiln characterized by a ceramic rail that connects the rollers of a chain belt. (2) The mechanism that blows atmospheric gas onto the workpiece from the ceiling and sides over the entire length of the furnace core tube consists of an atmosphere introduction tube that has many nozzle holes and is arranged along the ceiling of the furnace core tube, and a large number of It consists of an atmosphere introduction pipe that has nozzle holes and is arranged along both sides of the furnace core tube, and the rectifying atmosphere blowing mechanism consists of a tube that runs horizontally through the ceiling area of the front and rear cylinders in the width direction of the furnace. A conveyor-type kiln according to claim 1, wherein the pipe is provided with a large number of nozzle holes, and the cross-sectional area of the front cylinder and the rear cylinder decreases toward the opening. (3) The conveyor type kiln according to claim 1, wherein the ceramic rail is made of a plate, and the bottom of the hearth tube is sandwiched between the ceramic rail and the hearth plate. (4) The conveyor-type kiln according to claim 1, wherein the ceramic chain belt is meshed and driven by a drive sprocket on the outlet side, and the loose side makes rolling contact with the ceramic rail. (5) The conveyor type according to claim 1 of the utility model registration, which has several sets of link plates in the width direction and a rotatable roller between them, and the rotatable roller is supported by a protrusion of a ceramic rail. Firing furnace.
