A continuous industrial furnace comprising: an inlet; a heating zone; a cooling zone; and an outlet in this order, the continuous industrial furnace being configured to heat-treat a workpiece while conveying the workpiece from the inlet to the outlet, wherein at least a part of the heating zone comprises a furnace wall heat insulation structure, the furnace wall heat insulation structure comprising: an outer wall having one or more gas introducing ports; and a porous thermal insulation layer arranged with a gap on an inner side of the outer wall; and wherein the heating zone further comprises one or more exhaust ports for sucking and discharging the gas after the gas flows into the heating zone of the furnace from the gas introducing ports through the gap and the porous thermal insulation layer In this order and then flows toward the inlet side.

A method and plant for the thermal treatment of friction elements including a convective heating step which is performed within a convective tunnel oven. The friction elements are arranged laid, in an orderly manner, upon a plurality of trays each tray having a perforated resting plate upon which the friction elements are laid in a position next to one another only, but not overlapped. The trays are piled on top of each other whilst being kept distanced from one another in a stacking direction by an amount that is greater than the thickness of the friction elements. Groups of piled up trays containing the friction elements are arranged side by side on belt conveyor means that pass through the tunnel oven in order to transport the friction elements therethrough.

The invention relates to a method for sintering carbon bodies (16) in a furnace comprising at least a first furnace chamber (11) for receiving the carbon bodies, which are accommodated in a packing material (23), the carbon bodies being arranged between lateral chamber walls (12, 13, 21) of the furnace chamber, and the furnace chamber serving to form a preheating zone V, a heating zone H provided with a heating device, and a cooling zone A, wherein a packing material (23) made, at least in part, of a highly heat-conductive material is used.

A conveyor furnace includes a muffle having an inlet opening and an outlet opening, with a heating device for heating a volume delimited by the muffle, and a closed conveyor belt manufactured at least partially from metal. The conveyor furnace includes another heating device which is arranged so that, during the operation of the conveyor furnace, the heating device heats a section of the conveyor belt extending outside of the muffle.

The plate-formed grate element (1, 2) has a top wall (12), a bottom wall (13), a front end (14) and a back end (15). The front end has a lower inwardly curved wall portion (16) adapted to maintain a predetermined clearance with a back tip edge of a corresponding grate element. An internal cooling fluid chamber (18) includes an internal front cooling fluid channel (19) extending along the front end (14) of the grate element. The grate element has an outwardly curved front wall (22) having a nominal wall thickness varying by less than +35 percent and extending from the top wall of the grate element to the lower inwardly curved wall portion of the front end, and a front tip edge (23) of the front end is formed by the outwardly curved front wall at its connection with the lower inwardly curved wall portion.

An oven for baking a thermally curable binder in a mat of mineral fibers, including plural compartments through which the mat of fibers passes successively, the mat being compressed and transported through the compartments by gas-permeable upper conveyors and lower conveyors, each compartment having a length along a direction of movement of the mat and including a mechanism introducing a hot air flow, located either below or above the fiber mat, and a mechanism extracting the air after having passed through the mat, respectively arranged either above or below the opposite face of the mat, so that the binder is progressively brought to a temperature higher than its curing temperature. In one compartment the mechanism introducing hot air includes air inlets that open partly on openings formed on a first lateral side of the compartment and partly on openings formed on the opposite lateral side of the compartment.

The invention relates to a conveying system for conveying a material to be conveyed along a conveying path. The conveying system includes a conveying chamber in which the conveying path is arranged. At least one component of a conveying mechanism for conveying the material to be conveyed is arranged outside the conveying chamber. The conveying mechanism includes a traction drive having at least one traction element by means of which carrying elements can be moved in order to convey the material to be conveyed. The carrying elements are arranged in the conveying chamber and protrude through a through-opening out of the conveying chamber. Inside the conveying chamber and/or in the region of the through-opening, the surfaces of the carrying elements are at least partially provided with a thermal insulation material.

This application relates to a conveyor and a baking device. A traction rope may bring an electrode plate to move in a transport space. The traction rope may be of high flexibility and can more smoothly bring the electrode plate to move in various complex environments such as an arcuate oven, thereby effectively avoiding derailment or jamming of the conveyor in the oven and conveying the electrode plate more smoothly in the oven.

A continuous industrial furnace comprising: an inlet; a heating zone; a cooling zone; and an outlet in this order, the continuous industrial furnace being configured to heat-treat a workpiece while conveying the workpiece from the inlet to the outlet, wherein at least a part of the heating zone comprises a furnace wall heat insulation structure, the furnace wall heat insulation structure comprising: an outer wall having one or more gas introducing ports; and a porous thermal insulation layer arranged with a gap on an inner side of the outer wall; and wherein the heating zone further comprises one or more exhaust ports for sucking and discharging the gas after the gas flows into the heating zone of the furnace from the gas introducing ports through the gap and the porous thermal insulation layer In this order and then flows toward the inlet side.

A sublimation furnace has a first endless conveyor belt extending along a first axis through the furnace, with a chamber extending above and along that first conveyor belt. Vacuum trays placed on the first belt have products abutting sublimation images to be transferred to the product as the trays pass through the furnace. The furnace has a first sidewall with a slot extending along the sidewall and along the first conveyor belt. A second endless conveyor belt extends along but offset from the first axis. A plurality of vacuum pumps are connected to the second conveyor belt and move with that belt, with each pump connected by a hose passing through the slot during use of the furnace to a different vacuum tray on the first conveyor in order to evacuate the vacuum trays and press the images against the product for sublimation transfer.
