It is corresponding with the horizontal and vertical groove position on pedestal, size with longitudinal raised line, the planker ovalize, centre is provided with circle
Hole, below guide plate, below planker, walking beam column passes through circular hole, mounting hole one, mounting hole to guide plate to the pedestal
Two.
Used as a modification of the present invention, the pedestal is the prefabricated section made by Low Cement Castable.
Used as a modification of the present invention, the pedestal is divided into two pieces of left and right, middle to be connected by groove and convex arc.
Used as a modification of the present invention, the depth of the horizontal and vertical draw-in groove on the pedestal is 2-8cm.
As a modification of the present invention, lightening casting material filler is provided with inside the planker.
Used as a modification of the present invention, the gib block is higher by plane 1-2cm on guide plate.
The beneficial effects of the invention are as follows:
A kind of step heating-furnace of the present invention dry-type encapsulated device of double plankers, under guide plate, planker and guide plate
The furnace bottom visual plant such as side refractory material is hardly damaged;The step heating-furnace furnace bottom dry-type encapsulated effect of double plankers is more preferable, because of furnace bottom
Energy loss reduces 15% caused by sealing is bad;Furnace bottom good seal, it is ensured that steel structure of furnace bottom steel billet temperature is by 350 DEG C at sealing
150 DEG C are reduced to, the working environment of furnace bottom machine around is greatly reduced, the final service life for improving stove equipment saves energy
Source;Refractory material subtracts the artificial labour intensity for repairing furnace bottom using prefabricated section significantly, and aspect is quick, improves operating efficiency.

Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limitation the scope of the present invention.It should be noted that the word " preceding " for being used in description below,
" afterwards ", "left", "right", "up" and "down" refer to the direction in accompanying drawing, and word " interior " and " outward " refer respectively to direction or remote
From the direction of particular elements geometric center.
As illustrated, a kind of step heating-furnace of the present invention dry-type encapsulated device of double plankers, including pedestal 1, guiding
Plate 2, planker 3, walking beam column 4, the pedestal 1 are rectangle, are made up of refractory material, and mounting hole one is provided with the middle of pedestal 1
5, the both sides of mounting hole 1 are provided with horizontal and vertical draw-in groove 6,7, and the horizontal and vertical draw-in groove 6,7 is arranged in T-shaped, described
Guide plate 2 is rectangle, and centre is provided with mounting hole 28, and plane two ends are provided with gib block 11, the lower plane of guide plate 2 on guide plate 2
Both sides are provided with horizontal and vertical raised line 9,10, the horizontal and vertical draw-in groove 6,7 on the horizontal and vertical raised line 9,10 and pedestal
Position, size are corresponding, and the ovalize of the planker 3, centre is provided with circular hole 12, and the pedestal 1 is oriented to below guide plate 2
Below planker 3, walking beam column 4 passes through circular hole 12, mounting hole 1, mounting hole 28 to plate 2.
During work, walking beam column 4 is forward/backward, so as to drive up/down planker 3, the surface of guide plate 2 is being led over/under
Slided between bar 11, the width of its middle carriage 3 is than the few 2-3cm of width between two gib blocks 11, and the gib block 11 is high
Go out plane 1-2cm on guide plate 2, it is ensured that the movement that planker 3 can be freely, but will not tiltedly inclination angle it is excessive, make planker 3 always
Cover on mounting hole 28, lightening casting material filler 13, the double planker dry types of step heating-furnace furnace bottom are provided with inside the planker 3
Sealing effectiveness more preferably, 15% is reduced because furnace bottom seals bad caused energy loss;Furnace bottom good seal, it is ensured that furnace bottom steel at sealing
