(54) HEATING LINE FOR HEATING HEATING

FLAT INGOTS FROM DENTAL METALS

The purpose of the invention is to increase the production capacity and lower the weight of the equipment and the cost of production.

The delivered chain is reached by a t & l that the line is equipped with a device for applying protective coatings, containing a floor storage of ingots with feet, multi-stage trolleys for single-piece transfer of ingots, a cleaning chamber from filaments and applying protective

coatings, while these cameras are provided with lateral directions for the transport of ingots in an upright position.

FIG. 1 shows a flow line 15 for furnace heating of flat ingots of non-ferrous metals, a general plan view; Fig, 2 - view A on phage. one; in fig. 3 section & FIG. I; in fig. 4 shows a section in FIG. I.20

The proposed production line consists of a device for applying a protective composition (coating), which contains a floor storage unit I ingots in feet, two multi-position trolleys 2 for 25

double transfer, ingots; tilters of 3 ingots, roller-roll 4 with lateral directions of the thickness “1 5, cleaning chamber 6 and chamber 7 applying protective composition.

The composition of the stream line also includes: 30 transfer cart 8, pushers 9. | intended for transportation. and s (arrays of ingots on pallets (the latter are not shown on the drawings) in the heating furnaces Y. At the exit of 35 tote windows, there are unloading devices II, which are forward-looking agal beams and are used for receiving e-casings, pallets and y7 them for the role-, grade i2 of the rolling mill. The chain transfer 4Q gear conveyor 13 is intended for:

-shipping pallets and stacking for transfer. What telshsu 8.

Floor storage of 1 ingot by bars is a tangent device5 which is voidable in B1 of L-shaped arms 14, whose faces are ELEVED by centering screws which are driven by a counterbalance 15,

The MioPlayer 2 MvieioT trolleys are able to move along ramps 16 and are equipped with tick-borne grippers 17, as well as electric drives 18 for lifting j ingot and 19 moving trucks. How- . The 3 owners of the head and tail parts of the device for applying the zashit composition are similar in design and are intended for loading (unloading) ingots onto the live rolls (from it), respectively. By design, the tilter is a welded metal structure consisting of movable 2O and fixed 2.1 parts. The moving part is driven by a hydraulic cylinder 22,

The conveyor 4 is designed for transporting ingots in a vertical position sequentially through the cleaning chambers and applying a protective composition. The cleaning chamber is a device in which the ingots are cleaned using DC electrolytic plasmatrons 23, mounted (dummy) on the hinged suspensions 24. Due to the constant pressing of the support rollers 25 to the side surfaces of the ingots under the action of the counterweight 26, a constant the gap D between the working surfaces of the plasmatrons and the side surfaces of the ingots. Flushing of electrolyte residues and impurities from ingots is performed in another section of the purification chamber using hot water by the jet method. The solution circulation system (pumps, tanks, etc.) ensures the uninterrupted supply of electrolyte (aqueous solution of Noi-i BOD or into the flame lamps, as well as hot water to the nozzles for washing.

The protective coating chamber 7 is designed for applying a protective coating using a jet method. The Circulation System (solution heated tank, pumps) ensures uninterrupted solution delivery to chamber nozzles

From the warehouse of ingots located near the section of the furnace heating, the ingots are transferred by large stops to the production line for furnace heating. With the help of a bridge crane, the ingots are stacked into the floor storage device I, where they are centered. The multi-position trolley 2 puts ingots individually from the centering device onto the movable part 20 of the turner 3, which, turning on 9O, sets the ingot on the roller table in a vertical position (position on the edge). The live rolls 4 feeds the ingot into the cleaning chamber 6, where with the help of DC plasmatrons the ingot is cleaned, washed from the nozzles with hot water and sent to the protection application chamber 7. In chamber 7, the ingot is covered with a protective coating, zvg &

the roller table 4 is directed to the tilter 3 of the tail section, which places the slide checker in the flat position on its movable part. With the help of the clutch 17, the positioning trolley 2 of the tail part of the line removes the ingot from the movable part 20 of the turner and places it on the pallet mounted on the transfer carriage 8, which is moved to the corresponding furnace U, is stopped between the entrance to the furnace by the pusher. The pusher makes a stroke forward, pushing the ingot along with the pan into the heating furnace. Pallets are needed to move the ingots along the base of the furnace to the furnace without compromising the integrity of the protective composition.

At the exit of the furnace, the ingot enters the rolling table 12 of the rolling mill, and the pallets using the same roller table and chain transfer conveyor 13 are delivered to the transfer carriage 8, which moves to the transfer conveyor, takes the pallet and transports it to the multi-view carriage 2, where It is laid next ingot with a protective coating. After that, the cycle repeats.

The techno-economic effect is achieved through a set of equipment that provides for the continuous production of flat ingots, while the crane operation is provided only at the head of the flow and is accomplished with large stops, as well as due to the complete mechanization of technological operations (cleaning, applying protective coatings, transporting operations for loading, vypeuzke, transfer of pallets, etc.), which allows a 1.5-2 times increase in line capacity, reduce the number of service personnel, the mind "to reduce the weight of equipment performing these operations.
