SU442013A1 - Hot rolling device for porous belts - Google Patents

Description

The invention relates to the field of powder metallurgy, in particular, to devices for rolling porous strips of metal powders and alloys.

A device for hot sealing rolling of porous strips is known, which consists of a continuous furnace for heating strip trays and a rolling mill. Here, the furnace is adjacent to the rolling mill, and the rolled belts are cooled in air.

The proposed device differs from the known fact that for rolling tapes in a protective atmosphere and improving their quality, it contains a heat insulating gateway, hermetically connecting the furnace with the rolling mill, an empty pallets shop and a sealed container for receiving rolled tapes.

The drawing shows the proposed apparatus for rolling porous strips.

The device consists of a frontal furnace I and a rolling mill 2, interconnected by a heat insulating gateway 3.

The heating of the tape or package of sheets in the furnace and their transportation to the mill inside the sluice was carried out on pallets 4. The sluice

It is equipped with manipulators 5. The pallets with ribbons through the gateway move along the guides 6. The master manipulator 7 is designed as a pusher. Between guides 6 and mill 2

The drive rolls 8 are placed. On the other side of the rolls of the mill 2 is the receiving tank 9 for rolled strips. In order to collect the emptied pallets 4, the device is provided with a magazine (not shown in the drawing) located on the side wall of the airlock.

The rolls 8 have a mechanism Yu, which regulates the pressure on the belt, and an adjustable drive I,

IE compaction ensures that the sluice fits snugly to the mill rolls and creates tightness throughout the device. At the level of the upper roll of the rolling mill, on the feed side of the belt, there is a candle 13 for burning hydrogen leaking through the gap in the rollers.

The device works as follows

. On the pallet A- stack stack

porous sheets or tapes molded from metal powders. The pallet with the material is heated in the furnace I in the atmosphere of hydrogen or other protective gas, and then pushed into the gateway 3. There the pallet enters the guides using the pusher. The driver rolls 8 pick up a stack of tapes from the pallet and are fed to the rolls of the mill 2 for hot sealing rolling. Laminated tapes or sheets - enter the hermetic container 9, where they cool down. The emptied pallets are brought into the store, from where they are retrieved, for reloading. The proposed device allows rolling of porous tapes in any controlled atmosphere, the rolling process can be fully automated,
