The present technology relate to an equipment and method for drying an electrode substrate including a screen for distributing the flow of hot air, and according to the present technology, it is possible to uniformly dry the electrode substrate in the width direction.

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 provides a heat treatment furnace with stable conveyance, including a furnace body, a conveyance mechanism, a carrier locking mechanism, and a carrier unlocking mechanism. The furnace body is provided with an isolation zone, a drying zone, and a cooling zone in a product conveyance direction. The isolation zone, the drying zone, and the cooling zone are jointly provided with a product channel which extends through the furnace body. The drying zone includes at least one drying box body. Circulating heating modules are symmetrically disposed on two sides of each drying box body. The conveyance mechanism includes a carrier bearing surface. The carrier locking mechanism is arranged on the carrier bearing surface, and is used for locking the carrier on the carrier bearing surface. The carrier unlocking mechanism is at least arranged at an outlet of the product channel, and used for releasing the locking of the carrier.
