摘要:
A drop-out conveyor (10) for a pusher-type slab reheat furnace (12) having a sloped drop-out is disclosed. The drop-out conveyor comprises a plurality of reciprocating slab carts (20) movable between a first loading position within the furnace and a second discharge position outside of the furnace. A track (24) is provided for supporting each of the carts along the sloped drop-out of the furnace between the loading position and the discharge position. A mechanism (40) is provided for reciprocating each cart between the first position and the second position. The present invention additionally includes a device for removing the slabs from the slab cart to a roller table (16) at the discharge position.
摘要:
For burning electrode blanks, the latter pass in coaxial succeeding manner through a burning section and hot gas flows round them. This hot gas flow is segmentally regulated along the burning section. From the actual and desired values of this flow regulation is derived a control quantity for the fuel supply, which is used for heating with fresh hot gas the hot gas conveyed in the circuit, accompanied by the simultaneous burning of its charge of combustible constituents, this taking place stoichiometrically in such a way that no harmful oxygen is present in the fresh hot gas.

摘要:
A battery of stationary hearth furnaces, and method for using, for producing metallic iron nodules having a furnace having a stationary hearth, an inlet and an outlet; a heating chamber beneath the stationary hearth having heated fluids circulated thereto and heating reducible material on the stationary hearth; passageways circulating fluids, through ports from the furnace housing above the reducible material to the heating chamber beneath; burners and air inlets in the furnace and optionally in at least one passageway and a heating chamber for drying and heating the reducible material, driving off and burning volatile material, and forming metallic iron nodules; a loading device for loading reducible material and optionally hearth material onto the stationary hearth through the inlet; and a discharging device capable of discharging metallic iron nodules and optionally related material from the stationary hearth through the outlet.
摘要:
A pusher furnace includes a pusher assembly having first and second coordinated pushers for pushing load supports with loads to be heated thereon to provide continuous downstream movement of the load supports through a furnace section. A removal assembly includes a first removal mechanism which removes the load supports from the furnace section and a second removal mechanism which removes the loads from the first removal mechanism to facilitate the continuous downstream movement. The first removal mechanism preferably includes a parallelogram-type four-bar linkage for lifting the load supports and lowering them onto the second removal mechanism. Entry and exit plenums are connected to respective ends of the furnace section to provide a controlled atmosphere within the furnace section. The pusher and removal assemblies are timed with opening and closing of various gates of the plenums to maintain the controlled atmosphere.
