Description
Technical field
The utility model relates to hot rolling field, particularly relates to the stay-warm case in a kind of hot rolling heat holding hole.
Background technology
At present, in hot rolling technology, hot rolling heat holding hole is widely used, and is incubated by steel billet, plays the effect of save energy. For 1580 holding pits in prior art, each holding pit has high cover and low cover two stay-warm cases, and the structure of these two stay-warm cases is identical, and size is different. For height cover, as shown in Figure 1, two ends at this holding pit opening place are parallel is provided with two guide rails 111, some cover plates 112 have been spliced to form cover body part 113 along with parallel track direction, these cover body part two ends thus are slidably connected with this guide rail with the wheel 115 being wholely set on support by support 114, owing to taking welding machine to connect in the stitching portion of adjacent cover plate. In long-time working process, owing to the span of holding pit bell is big, adds himself gravity and high-temperature factor, cause its original design center cell to reduce to camber, and cause two edge position-limited wheel deviation positions laterally, lose position-limiting action. Each holding pit has high cover and low cover two stay-warm cases, wherein low cover deformation comparison is serious, bell produces the decrease in strength of thermal expansion and bell entirety after being heated, simultaneously, the main frame of bell produces bigger lower flexure strain, thus cause jam between high cover and low cover, often cause holding pit holding furnace to jump electricity, seriously have impact on the normal operation of equipment. And wheel etc. cannot adjust after cheating lid lower flexure strain, takes off and outer shifting outside causing both sides wheel, thus cause serious gnawing rail and the rail fault that falls, cause wheel heavy wear and easily break electric limiting switch. And cheat lid wheel track beam base plate and also have problems, holding pit track girder base plate is the I-beam of 8MM, and the top panel inside its holding pit subsides seriously, the rail meter of fixed rail is not worked, track cannot be fixed, thus produce fault-time, affect hot-loading and hot-conveying normal procedure.
Lid is due to the feature of himself structure, it is easy to produce collapse-deformation. It is poor that this directly results in holding pit, holding furnace stopping property, a large amount of loss of heat energy. When lid stopping property is poor, the temperature loss of slab fast especially, cannot ensure its insulation demand, more not meet the policy that company is energy-saving and cost-reducing. Especially, when bell produces due to collapse-deformation such as above-mentioned bell, wheel, guide rail, the fault such as spacing, owing to holding pit, holding furnace ambient temperature are higher, long-time, highly difficult repairing can directly have influence on the process of hot-loading and hot-conveying especially.

Embodiment
Below, by reference to the accompanying drawings, structure of the present utility model and principle of work etc. are further described.
Fig. 1 is the vertical view of the stay-warm case in hot rolling heat holding of the present utility model hole, as shown in Figure 1, the stay-warm case in hot rolling heat holding of the present utility model hole is used for covering and heat insulating hole 1, is incubated by the steel billet being stored in holding pit 1, it is arranged on track 2, it is possible to slide along track 2. Track 2 is set in parallel in the opening two ends of holding pit 1, and the bearing of trend of track 2 is the slip direction of stay-warm case.
The stay-warm case in hot rolling heat holding of the present utility model hole comprises the cover body part 3, bracing frame 4 and the wheel 5 that connect successively from top to bottom, wherein, cover body part 3 is set on track 2 bearing of trend parallel 5 cover plates 31 being welded, and the long side direction of each cover plate 31 is all vertical with the bearing of trend of track 2. With in prior art, compared with cover plate is parallel with track direction, not easily produce to subside in weld.
Being respectively arranged with bracing frame 4 in the lower section at the two ends of cover body part 3, as seen in figures 3-5, bracing frame 4 is configured to cover body part 3 be supported. In present embodiment, bracing frame 4 is 4, often holds each 2 configurations, but can also be adjusted to 4��8 according to actual needs. The lower section of bracing frame 4 is provided with wheel 5. Setting device 51 it is connected with between wheel 5 and bracing frame 4.
Adopt between bracing frame 4 and cover body part 3 and it is welded to connect, below the connection relation between wheel 5 and bracing frame 4 is described. As shown in Figure 4, the lower end of bracing frame 4 has offered four waist-shaped holes 41, and the long side direction of waist-shaped hole 41 is vertical with the bearing of trend of track 2.
The bearing 51 of wheel 5 is fixed on the lower end of setting device 52, and the upper end of setting device 52 is installed on bracing frame 4 by bolt 53 is inserted waist-shaped hole 41, thus wheel 5 is installed on bracing frame 4. The effect of waist-shaped hole 41 is immediately finely tuned when generation deviation track by wheel 5, cover body part 3 and the skew of bracing frame 4 occurred level, by the adjustment to bolt 53, wheel 4 can be moved to the surface vertical range of track 2, it is possible to avoid wheel 5 to occur gnawing rail phenomenon. Compared with one-body molded with bracing frame with wheel in prior art, possesses preventive effect.
In addition, in present embodiment, above cover body part 3, also it is provided with lacing wire beam 6. Lacing wire beam 6 is in arch. Being equivalent to by power of lacing wire beam 6Then haveWherein l is span once, and l is more little, and uniformly distributed load is more little, under equal conditions, the load of beam is more little; The length of beam is more long, and under equal conditions, maximal bending moment is more big. So, it is contemplated that the welding mode of beam being changed, therefore in the present embodiment, lacing wire beam 6 adopts the mode of welding to be connected with cover body part 3. Lacing wire beam 6 one-tenth arches, go out distance cover body part 3 the farthest away in mid-way. And, lacing wire beam 6 is equal with the quantity of cover plate 31, is 5 groups, is separately positioned on above each cover plate 31, ensures that the stay-warm case of present embodiment does not subside further, and effect reduces the lower amount of deflection of beam, ensures that stay-warm case entirety is stable, safeguards and normally produce.
In sum, the welding direction that the stay-warm case in hot rolling heat holding of the present utility model hole takes cover plate 31 changes, sets up setting device 52 and arrange the 6 three kinds of technique means actings in conjunction of lacing wire beam, prevents subsiding of stay-warm case, ensures production safety.
Above, it is only schematic description of the present utility model, it will be obvious to one with ordinary skill in the art that, on the basis not deviateing principle of work of the present utility model, it is possible to the utility model is made multiple improvement, and this all belongs to protection domain of the present utility model.
