Definitions
- the invention relates to furnace flaps for winding furnaces which can be used, in particular, in Steckel rolling mills, in which a hot-rolled strip is reversibly wound up and down and possibly heated on the inside of a furnace during transport back and forth, including guide tables for threading mounted on the movable furnace flaps of the winding furnace and / or guiding the rolled strip.
- the winding furnace known from the aforementioned document comprises an upper housing part and a lower housing part, which can be firmly connected to one another, as well as an oven drum in the housing with means for receiving a rolled strip.
- the housing has a bottom part separate from the lower housing, the bottom housing part being movable relative to the lower housing. As a result, the bottom case part can be moved even when the inside of the oven is still hot.
- the bottom housing part is designed and arranged so that it can be moved or removed together with movable roller table rollers. As a result, the changeover time is shortened from, for example, 30 hours to about 5 hours.
- furnace flaps of the type mentioned in the preamble of claim 1 with the invention in that the furnace flaps and the associated winding furnace are separate structures, that the furnace flaps are arranged on a part of a roller table frame located below the winding furnace, and that each furnace flap is in at least two foldable elements are divided and both fold elements are connected via a flap bearing and are pivotally attached.
- roller table frame can be moved on guide rails with the furnace flap out of the radiation area of the winding furnace.
- furnace flaps can be attached to the sliding roller table underneath, so that the furnace flaps can be moved out of the radiation area of the furnace for maintenance.
- the oven tables and flaps can then be easily serviced.
- the operation of the flaps and their movement elements can also be made easier by the use of hydraulic cylinders.
- An embodiment of the device according to the invention further provides that the flap bearing is mounted on the roller table frame on the drive and operator side on at least one console.
- the movable part of the roller table frame is pushed onto adjustable support points when it is reinserted.
- the exact positioning in the rolling direction can be achieved by a guide at the point of contact.
- roller table frame is locked according to the invention by clamping cylinders.
- pivotable flap elements of the furnace flap are each assigned at least one hydraulic cylinder, which is preferably arranged on the operating side.
- the design of the furnace flap according to the invention is characterized in that it is arranged on the console so that it can be adjusted in height.
- FIG. 1 shows a sectional view of a plane xx in FIG. 4 a winding furnace above a roller table with a furnace flap completely closed for the free passage of a rolled strip
- FIG. 2 shows the winding furnace according to FIG. 1, but with the part of the furnace flap partially open and lowered obliquely towards the roller table,
- FIG. 3 shows the winding furnace according to FIG. 1, but with the furnace flap completely open and inclined to reel a rolled strip in threading mode
- Figure 4 shows the roller table frame and the winding furnace arranged behind it in the section of a plane perpendicular to its running direction.
- the furnace flap 2, 2 ', 2 "according to the invention and the associated winding furnace 1 are separate structures. These are arranged on a part 4' of the roller table frame 4 located below the winding furnace 1.
- the furnace flap is in at least two elements 2 ', 2 which can be folded relative to one another "can be divided, which are articulated to one another via a hinge 7 which is firmly connected to the part 4 'of the roller table frame 4 and is designed as a flap bearing. This results in the possibility of forming a lower opening in the housing of the winding furnace 1, which has a favorable effect on the accessibility of the furnace interior, for example during repair or revision work.
- the front flap part 2 ' is draulic cylinder 3 'raised obliquely to the front, whereas the rear flap part 2 "still remains in the horizontal position.
- the two flap parts 2', 2" are connected and supported together at one pivot point with the flap bearing 7.
- the flap bearing 7 is in turn mounted on the roller table frame part 4 'on the drive and operating side (the operating side is provided to the left of the plane xx in FIG. 4) on at least one bracket 8, 8'.
- FIGS. 1 to 4 show the motor-driven furnace drum 12 arranged in the interior of the winding furnace 1 with its reel mounting 13, 13 '.
- the flap bearing 7, the bracket 8 for flap bearing 7 and the hydraulic cylinders 3 for the pivoting movement of the flap parts 2, 2 ' can also be seen in FIG.
- the roller table itself is equipped on its drive and operating side with the console 8, 8 ', which is used to hold the flap bearing 7.
- the hydraulic cylinders 3 or 3 'or 3 "are assigned in the same order to the furnace flap or its parts 2', 2", as can be seen, for example, from FIG. 3.
- the hydraulic cylinders 3 ′, 3 ′′ are also fastened to the roller table frame part 4 ′ and can be moved together with the latter out of the roller table and brought into a maintenance position.
- roller table frame part 4 ' is pushed onto the adjustable support points 9. As soon as the exact positioning of the roller table frame part in the rolling direction at the support point 9, 9 'is reached, the roller table frame part 4' is locked by clamping cylinders 10, 10 '.
- FIG. 3 shows, in the threading operation, the incoming rolling strip 11 is raised by hydraulic lifting of the rear flap elements 2 ', 2 "to such an extent that it engages in the threading gap 15 of the furnace drum 12 and is detected and carried along during its rotational movement.
- the design of the furnace flaps according to the invention, fastened on the extendable roller table for winding furnaces, is uncomplicated and extremely expedient and decisively improves the maintenance options of the winding furnaces.
