Extend the moving beam and move the billet 10-1 to the furnace.
It is positioned at the center of the charging table 17.

F-2 in FIG . 3B is a moving beam.
7 after F-1 stroke, steel billet 10-1 into furnace
7 shows a stroke advanced to the center of the rule 17. Cut out
By extending the piston rod of cylinder 8-2
Cutting head 8-1 from the upper surface of the furnace charging table 17
And load the billet 10-1 on the furnace charging table 17.
By doing so, the billet 10-1 is placed on the furnace charging table 17.
It is cut out. Hereinafter, this is repeated to cut out all ten billets.

(2) Transfer of the billet block to the cut-out position The moving beam 7 is moved by the shift cylinder 13 to the origin position 9.
Retreat until The moving beam 7 is cycled while the cutting head 8-1 is lowered (FIG. 2B).
The billet blocks 11 and 12 move forward by one pitch, and 11 is a cutout position.

(3) Rejection of steel slab The steel slab cut out on the furnace loading table 17 is rejected.
When moving to the skid 14, as shown in FIG.
As described above, the user can move by performing the following procedure.
Anti-reject of billets loaded on the furnace charging table 17
On the skid 14 side, raise the cutting head 8-1
From lever to advance the walking beam 7, billet cut f
8-1 and moved to the reject skid 14
can do.

In the above operation, during cutting of the billet,
Alternatively, when extruding the billet into the reject skid 14
Even in the middle, the upper surface of the moving beam 7 has 15 fixed beams.
Because it is located below the upper surface of the
That is, a new billet is suspended by crane on 15 rows of fixed beams.
Can be taken down.
