Heating and/or temperature-maintaining furnace (11) for slabs (35), which includes lateral intake (12a) and outlet (12b) roller conveyors the axis of which is at a right angle to the axis of movement of the slabs (35) within the furnace (11), the roller conveyors (12a-12b) consisting of a plurality of roller-bearing bogies (13) able to move at a right angle to the axis of the roller conveyors (12a-12b), the roller-bearing bogies (13) having a first maintenance/replacement position (13a) outside the furnace (11) and a second working position (13b) in which they cooperate with the inside of the furnace (11), means being also included for the movement of the slabs (35) in the furnace (11), the rollers (10) being supported at both their ends on the roller-bearing bogie (13) by supporting means (19) and being driven by appropriate motor means (21), the supporting means (19) and motor means (21) being located outside the furnace (11) when the roller-bearing bogie (13) is brought to its second working position (13b), the ends of the rollers (10) being accessible from outside the furnace (11), an insulated bottom (39) and insulated sidewalls (22) being included in the roller-bearing bogie (13) to protect the roller-supporting means (19) and the motor means (21) associated with the rollers (10).
摘要:
A firing kiln for ceramic products, and the like, comprising at least a first channel (2) and at least a second channel (3) defined between kiln walls (1), their respective first feeding means (4a) of the products in at least said first channel (2) and second feeding means (4b) of the products in at least said second channel (3), respective firing means (5) of the same products, means of exchange (6) of hot air for sending pre-determined air flows between respective areas of the first channel (2) with areas of the second channel (3). The means of exchange (6) comprise a distribution of damper valves (22), provided with respective ports (23), designed to collect and adjust in a unidirectional manner the flow of hot air from the first end cooling area (10) to the second preheating area (13), and from the second end cooling area (15) to the first preheating area (8).
摘要:
The invention relates to a device for continuously and catalytically removing binder from metallic and/or ceramic moulded bodies produced by powder injection moulding, the device comprising a binder-removing furnace, through which the moulded bodies pass in a direction of conveyance and in which they are brought to a suitable processing temperature, a conveying device, for introducing a process gas which is needed to remove the binder and contains a reaction partner, at least one device for introducing a protective gas into a reaction chamber of the binder-removing furnace, and a burner, for burning the gaseous reaction products that result from the binder removing process, one or more devices being included which lead to a targeted flow of the process gas in the device transversely to the direction of conveyance.
摘要:
A heating furnace system is provided for receiving finite lengths of workpieces from one or more continuous casters and from a supply of heated workpieces at a temperature suitable for rolling in a hot rolling mill (6). The system includes, in one aspect, a holding furnace (4) receiving a workpiece during continuous casting until it is severed by a cutoff device (3) to prevent unwanted cooling. The workpiece is fed from a holding furnace (4) to a heating furnace (5) wherein it is deposited onto one of a series of vertically spaced supports in a heated section where it remains static throughout the heating process. After heating the workpiece is removed from the stationary supports and returned to rollers of the hearth for discharge from the furnace to a rolling mill (6).
