Description
Technical field
The invention belongs to metallurgy industry mechanical equipment technical field, be specifically related to the two dry-type encapsulated device of planker of a kind of step heating-furnace.
Background technology
Low temperature walking beam heating furnace in current most domestic, all adopt double-deck planker dry-type encapsulated, if Fig. 2 Fig. 3 is the dry-type encapsulated sectional view of the double-deck planker of heat treatment furnace walking beam column, its principle of work is: furnace bottom machine walking beam is forward/backward, thus drives up/down planker to slide along gib block (one-sided add gib block) direction on guide plate surface over/under.
Quenching furnance walking beam is in operational process, because burner hearth is in temperature-rise period, there is swelling in bottom refractory, in appearance, planker and guide plate guiding rib spacing increase to 10cm by intrinsic 2cm, thus walking beam drives upper planker deviation phenomenon, in such one side, planker at the volley, guide plate at the bottom of stationary furnace can be collided, life-time service causes very large impact to furnace bottom machine equipment, go up refractory castable on the downside of guide plate directly to damage in collision process simultaneously, the dry-type encapsulated effect can not playing sealing of final double-deck planker, make bottom temperature higher, cause the loss of heat.
Summary of the invention
For solving the problem, the invention discloses the two dry-type encapsulated device of planker of a kind of step heating-furnace, by mould material and upper guide plate design improvement, thus reinforce on the downside of upper planker, play walking beam column planker in drive forward/backward more firm, thus the effect that stopping property is strengthened.
For achieving the above object, technical scheme of the present invention is as follows:
The two dry-type encapsulated device of planker of a kind of step heating-furnace, it is characterized in that: comprise pedestal, guide plate, planker, walking beam column, described pedestal is rectangle, be made up of refractory materials, waist shaped hole one is provided with in the middle of pedestal, waist shaped hole one both sides are provided with horizontal and vertical draw-in groove, described horizontal and vertical draw-in groove is in T-shaped arrangement, described guide plate is rectangle, centre is provided with waist shaped hole two, on guide plate, plane two ends are provided with gib block, guide plate lower plane both sides are provided with horizontal and vertical raised line, horizontal and vertical draw-in groove position on described horizontal and vertical raised line and pedestal, size is corresponding, described planker ovalize, centre is provided with circular hole, described pedestal is below guide plate, guide plate is below planker, walking beam column is through circular hole, waist shaped hole one, waist shaped hole two.
As a modification of the present invention, described pedestal is the prefabricated section made by Low Cement Castable.
As a modification of the present invention, described pedestal is divided into two pieces, left and right, and centre is connected with convex arc by groove.
As a modification of the present invention, the degree of depth of the horizontal and vertical draw-in groove on described pedestal is 2-8cm.
As a modification of the present invention, described planker inside is provided with lightening casting material weighting material.
As a modification of the present invention, described gib block exceeds plane 1-2cm on guide plate.
The invention has the beneficial effects as follows:
The two dry-type encapsulated device of planker of a kind of step heating-furnace of the present invention, on the downside of guide plate, planker and guide plate, the furnace bottom visual plant such as refractory materials is not fragile; The two dry-type encapsulated better effects if of planker of step heating-furnace furnace bottom, because the bad energy loss caused of furnace bottom sealing reduces 15%; Furnace bottom good seal, ensures that sealing place steel structure of furnace bottom steel billet temperature is reduced to 150 DEG C by 350 DEG C, greatly reduces the Working environment of furnace bottom machine around, final work-ing life of improving stove equipment, save energy; Refractory materials adopts prefabricated section greatly to subtract the artificial labour intensity repairing furnace bottom, and aspect is quick, increases work efficiency.

Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, following embodiment should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric centre respectively.
As shown in the figure, the two dry-type encapsulated device of planker of a kind of step heating-furnace of the present invention, comprise pedestal 1, guide plate 2, planker 3, walking beam column 4, described pedestal 1 is rectangle, be made up of refractory materials, waist shaped hole 1 is provided with in the middle of pedestal 1, waist shaped hole 1 both sides are provided with horizontal and vertical draw-in groove 6, 7, described horizontal and vertical draw-in groove 6, 7 in T-shaped arrangement, described guide plate 2 is rectangle, centre is provided with waist shaped hole 28, on guide plate 2, plane two ends are provided with gib block 11, guide plate 2 lower plane both sides are provided with horizontal and vertical raised line 9, 10, described horizontal and vertical raised line 9, 10 with pedestal on horizontal and vertical draw-in groove 6, 7 positions, size is corresponding, described planker 3 ovalize, centre is provided with circular hole 12, described pedestal 1 is below guide plate 2, guide plate 2 is below planker 3, walking beam column 4 is through circular hole 12, waist shaped hole 1, waist shaped hole 28.
During work, walking beam column 4 is forward/backward, thus drive up/down planker 3 to slide between gib block 11 on guide plate 2 surface over/under, the width 2-3cm fewer than the width between two gib blocks 11 of its middle carriage 3, described gib block 11 exceeds plane 1-2cm on guide plate 2, ensure that planker 3 can movement freely, but can not tiltedly inclination angle be excessive, make planker 3 cover on waist shaped hole 28 always, described planker 3 inside is provided with lightening casting material weighting material 13, the two dry-type encapsulated better effects if of planker of step heating-furnace furnace bottom, because the bad energy loss caused of furnace bottom sealing reduces 15%, furnace bottom good seal, ensures that sealing place steel structure of furnace bottom steel billet temperature is reduced to 150 DEG C by 350 DEG C, greatly reduces the Working environment of furnace bottom machine around, final work-ing life of improving stove equipment, save energy.
The present invention changes described pedestal 1 into made by Low Cement Castable prefabricated section, and its advantage is: 1) in mould material, calcium oxide content is lower, can reduce the eutectic phase generated in material, thus improve refractoriness, hot strength and slag resistance; 2) cement-hydrate generated after blanks and moulding and conserving is few, and there is not a large amount of hydration key when heated baking and destroy and problem that medium temperature intensity is declined, but sinter gradually along with the raising of thermal treatment temp, intensity also improves gradually; 3) water requirement of mould material reduces greatly, therefore void content is low, volume density is high, indeformable, the degree of depth of the horizontal and vertical draw-in groove 6,7 on described pedestal 1 is 2-8cm, and pedestal 1 is combined with guide plate 2 closely, walking beam column 4 drives planker 3 deviation phenomenon can not occur, and pedestal 1 adopts prefabricated section greatly to subtract the artificial labour intensity repairing furnace bottom, aspect is quick, increases work efficiency.
In order to change pedestal 1 more efficiently, described pedestal 1 is divided into two pieces, left and right by the present invention, and centre is connected with convex arc 14 by groove 15, changes more efficient and convenient.
Technique means disclosed in the present invention program is not limited only to the technique means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic arbitrary combination.
