Abstract: A carrier transport system transports a plurality of carriers by a transport conveyor into a heating furnace, advances a comb-shaped carrier stopper having a plurality of protrusions toward the carriers, moves the carriers by the transport conveyor in a transport direction to engage cutout grooves, provided respectively for the carriers, with the protrusions of the carrier stopper to thereby position the carriers at a time. The carrier transport system advances the carrier stopper toward the carriers to insert distal ends of the protrusions of the carrier stopper into insertion holes, and then determines, on the basis of a moved distance X of the carrier stopper, whether the carriers are properly positioned.

Abstract: The invention provides a tunnel kiln for firing ceramic porous bodies which can fire ceramic porous bodies containing organic binders in a shorter period of time than in conventional methods without producing breaks or requiring nitrogen gas. The tunnel kiln includes a preheating zone 1, a firing zone 2, and a cooling zone 3 and fires the ceramic porous bodies loaded on a carriage 7 by driving it in a furnace. A heat storage regenerative burner 10 is used as means of heating the firing zone 2 so that low-oxygen-concentration exhaust gas discharged from the heat storage regenerative burner 10 may be returned to an exhaust gas return line 14 and supplied into the preheating zone 1. The exhaust gas return line 14 may be provided with a combustion device 17 that reduces the oxygen concentration by consuming oxygen contained in the exhaust gas.

Abstract: A conveyance section positioning method has carrier pallets on which workpieces are fixed, a conveyer, a heating furnace for heating the workpieces, and a positioning mechanism for positioning the carrier pallets, and the method stops the carrier pallets at predetermined positions. The heating furnace has halogen heaters for heating the workpieces. The carrier pallets each have projections and output grooves. Comb tooth-shaped stopper projections engaging with the projections are formed on a carrier stopper. When the carrier stopper is moved forward, the stopper projections and the projections are engaged with each other. In this one operation, the carrier pallets are positioned at places corresponding to the halogen heaters, and then the workpieces are heated.

Abstract: A thermal system for separating out co-mingled metals in almost pure form, the system including a tunnel kiln having temperature zones through which the co-mingled metals are conveyed and progressively heated until at least one metal of the co-mingled metals melts thereby separating the melted metal from the other metal or metals of the co-mingled metals. The system includes molten metal catch basins for collecting the melted metal which are arranged beneath a conveyor on which the co-mingled metals are transported within the kiln. The catch basins are tapped to the outside of the kiln so that as the various metals melt out at progressively higher temperatures, they can be collected into cast iron chills or other collection devices to form pure ingots.

Abstract: Systems and methods for use in processing raw material (e.g., iron bearing material) include a linear furnace apparatus extending along a longitudinal axis between a charging end and a discharging end (e.g., the linear furnace apparatus includes at least a furnace zone positioned along the longitudinal axis). Raw material is provided into one or more separate or separable containers (e.g., trays) at the charging end of the linear furnace apparatus. The separate or separable containers are moved through at least the furnace zone and to the discharging end where the processed material is discharged resulting in one or more empty containers. One or more of the empty containers are returned to the charging end of the linear furnace apparatus to receive further raw material.
