The present invention relates to a reducing and fusing method and device for a metal oxide using a hermetically sealed crucible. More specifically, the present invention relates to a reducing and fusing method and device for a metal oxide using a hermetically sealed crucible, whereby a reducing atmosphere in which a reducing agent and oxygen readily react can be formed within the crucible, and whereby a metal oxide can be continuously reduced and fused within the same device. The reducing and fusing method for a metal oxide using a hermetically sealed crucible of the present invention comprises the steps of: introducing a metal oxide into a crucible; sealing the crucible; and reducing and fusing the metal oxide by heating the sealed crucible. The reducing and fusing device comprises: a crucible containing a material to be reduced and fused; and a furnace which contains the crucible and heats the crucible, wherein the crucible is hermetically sealed.

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.

Die Erfindung betrifft ein Verfahren zum Sintern von Kohlenstoffkörpern (16) in einer Ofeneinrichtung mit zumindest einer ersten Ofenkammer (11) zur Aufnahme der in einem Packungsmaterial (23) aufgenom- menen Kohlenstoffkörper, wobei die Kohlenstoffkörper zwischen seitlichen Kammerwänden (12, 13, 21) der Ofenkammer angeordnet werden, und die Ofenkammer zur Ausbildung einer Vorwärmzone V, einer mit einer Heizeinrichtung versehenen Heizzone H und einer Abkühlzone A dient, wobei ein zumindest anteilig aus einem hoch wärmeleitfähigen Werkstoff gebildetes Packungsmaterial (23) verwendet wird.
摘要:
A method for treating a piece (1) made of a first porous material (8) with a second material (2) when this second material is in liquid state, said second material (2) being suitable for infiltration when a predetermined temperature range (DTi) and a predetermined field of infiltration pressure (Dpi), comprises the steps of: - providing a crucible (4) suitable for containing the piece (1) and the second material (2) and capable of withstanding the temperatures and pressures for the infiltration of the second material (2) in the piece (1); providing a cover (5) for the crucible (4) suitable for closing the crucible creating a chamber (6) inside the crucible; placing the piece (1) and the second material (2) in said crucible chamber (6), when this second material is not yet in liquid state; -subsequently closing the crucible (4) with the cover (5); -at a pressure (pa or pal)- unsuitable for the infiltrations of the second material in the first porous material, raising the temperature of the piece (1). and the second material (2) contained in the crucible up to a predetermined temperature (T2) suitable for liquefying said second material (2) for making it suitable for infiltration in said piece (1) made of first porous material; - subsequently, lowering the pressure to a predetermined pressure value (p2) lower than the previous pressure (pa or pal) and allow the infiltration of the second material (2) in said piece (1) made of first porous material (8).
摘要:
A method of heating an article (29) with microwave energy is described in which a thin layer (34) of a highly microwave absorbed material is provided around at least a portion of a container (31) made of microwave transparent material. The article (29) to be heated is placed at a position within the container (31) where the article (29) is adjacent the thin layer (34) of highly microwave absorbent powdered material, and microwave energy is applied to the container (31).

摘要:
The food pan assembly of the present disclosure includes a food pan with a well for storing food, and two separate heating pads for supplying heat to food that may be placed in the pan. The heating pads are connected to an exterior side of the pan on a bottom and side surfaces. This allows for improved flexibility in heating options over what is currently available. The heating pads can be independently powered and controlled, according to specific demands for the food to be heated.
