3.1.3Furnace description



-Ladle are mounted within a priority frame activated by hydraulic cylinders

-Induction heater is made of steel frame supporting induction coil which is



cooled by water

-Electric transformers are water cooled type

-System include cooling water

-Hydraulic Power Unit for hydraulic cylinders



3.2- Vertical Ingot induction Furnace loading hopper made of fabrication steel



Loading of the hopper is made of line and transferred toward furnace ladle



by electric motor. Furnace hood being installed door open; load is dropped



inside the ladle by vibration of the bucket, vibration being made through



electro-mechanical device installed in between the fix frame and movable



frame.





3.3- Vertical Ingot Caster



Molten metal is tapped into the mold. The mold is 300mm height. The mold is



water cooled to solidify the heat metal directly in contact with it. In the



mold after solidification the level of the dummy bar cast iron made and



closing the bottom of the mold is going down up to

7.6meters. The dummy bar position is chain actuated in order to follow ingot



solidification all along the ingot length.

Once the dummy bar is down up to seven meters. The ingot is withdrawn by



lifting the dummy up bar pushing the ingot to the level above the mold where



chains are placed around the ingot and the crane is used to complete



extraction.

Carting speed can be adjusted by regulating the amount of metal in the mold.



-Mold heights for CuNi: 300mm

-Casting speed for CuNi : 110mm/minutes





3.4- Ingot automatic handling lift and carriage to storage area and ingot saw



After removing ingot one by one from caster, using chain and cable lifted by



the crane (once the demi bar is near top position). Ingot is delivered on two



wood made supports on floor level. Ingot inspection is made. Automatic lifter



pile up to six ingots on a carriage and then unloaded on roller table and



transferred to the saw. Roller table receive ingot which will have both end



cut by the ingot saw after rotating 180C by the lifting device. Then ingot is



delivered by transfer car to the final storage. Transfer car stroke 9 meters



and speed 6m/minutes.

-Ingot width : 520 mm

-Thickness : 225 mm

-Length before cutting : 5200 mm to 7600 mm

-Net length : 4700 mm or 7000 mm

-Maximum weight : 6T





3.5- Ingot saw



Ingot saw Wagner made is used to cut ingot both ends. Ingot is supported by



roller table. Saw design Data are:

-Power: 45KW

-Vertical Blade diameter : 1090mm

-Blade thickness : 7mm





3.6- Ingot saw chips vacuum and filtrations



Scrap chips produced during cutting both ends are vacuumed using air section



and filtrated through cyclone located outside saw building chips are collected



in a chips scrap bucket located under the cyclone.





3.7- Ingot external storage



After cutting both ingot ends with the saw, Ingots are transferred one by one



by a gear motor transfer car to the automatic storage building equipped with



loading and unloading crane. Buildings steels structure are to be dismounted



with the storage crane.

-Storage dimensions :50 meters length and 8 meters wide

-Storage capacity : 2000Tons

-Crane capacity : 5Tons

-Crane traveling speed : 1m/s





3.8- Ingot preheating and reheating furnaces



From ingot storage building, each ingot is transferred by the transfer car



back to the gas preheating furnace charging table. A set of 3 ingots are



loaded each time on threading table using local overhead crane and up ender,



each ingot is dropped into is individual furnace casing. Once ingot reach



300C, unloading is made by the local overhead crane which removes each ingot



from its gas furnace casing, and shift it toward electric furnace loading



ingot car driven by rack and pinion. After reaching 900C, unloading cars



remove heated ingots from the furnace, the overhead crane lifting fork and



load on the roller table by the up ender toward to hot strip mill.
