Abstract
The utility model relates to a brick supporting plate of a heating furnace, which comprises a brick supporting plate body and a support frame, wherein the rear end of the brick supporting plate body leans against the supporting frame in a suspension way; the supporting frame is connected with a furnace shell plate of the heating furnace; and a flange is arranged at the front part of the brick supporting plate so as to fix a refractory brick arranged on the plate. Compared with the prior art, a movable suspending and leaning structure is adopted to be beneficial for thermal expansion of the structure, so that the brick supporting plate is convenient to construct, has good plainness and is difficult to deform; the brick supporting plate is not directly contacted with the furnace shell plate, so that only a little heat is transferred by the metal brick supporting plate, and the temperature of a furnace shell wall is low, thereby reducing local overheating and heat dissipation loss of the furnace; particularly, the flange structure is arranged on the brick supporting plate to prevent the brick from sliding outward and play a key role in keeping the stability of a furnace wall; and the brick supporting plate can adopt nickel-saving heat-resistant steel (Cr 24 Ni 7 Si N) instead of the traditional Cr 25 Ni 20 and Cr 25 Ni 12 material so as to reduce the cost and save precious metal resource.
Description
Technical field
The utility model relates to the heating furnace parts, especially relates to a kind of heating furnace brick plate.
Background technology
Brick plate is parts that are used for heating furnace lining structure rest refractory brick, it is very important and requisite parts for light-duty brick hold structure furnace wall, especially to high-temperature heater (as the ethane cracking furnace in the petrochemical plant, hydrogen manufacturing conversion furnace etc.), the quality of the structure and material of brick plate, the quality of construction and installation all directly have influence on the radiation loss of service life, stove shell wall surface temperature and stove appearance of stability, the furnace lining of furnace wall structure.
A kind of good brick plate structure can make things convenient for the construction and installation of brick plate itself; Guarantee the stable of furnace wall brick structure and moving outward of being difficult for taking place brick, flare, collapse; Can also reduce high temperature from the brick plate unofficial biography, thereby reduce the furnace shell wooden partition surface temperature at this place, reduce the hot-spot phenomenon on furnace shell plate surface, and then reduce the radiation loss of stove, improve the thermal efficiency of stove.
Existing heating furnace supporting plate brick is commonly used mainly contains following two kinds of forms, first kind be brick plate directly with furnace shell plate welded structure, the brick plate of this kind form directly is welded on the furnace shell plate owing to the plate face, and is bigger by the heat of metallic plate unofficial biography; Because adopt long steel plate usually, adopt Welding Structure to deform easily again, high temperature uses the expansion of plate also easily to cause the distortion of plate down.Second kind is that brick plate is connected with the support bracket bolt that is welded in the furnace shell plate in advance, and this kind structure adopts the short brick plate that welds the lower support plate one by one in advance, is connected on the slotted-angle shelving that welds with the furnace shell plate with bolt.Avoid the welding of long steel plate like this and easily deformable problem when using, and brick plate does not directly contact with the furnace shell plate, although angle steel is welded on the furnace shell plate, but brick plate may be always much better than directly contacting with the heat conduction situation of furnace shell plate mediate contact, but the shortcoming of this kind structure is but single brick plate is made poor quality and angle steel welding quality when bad that adjacent brick plate levelness is regulated and had any problem slightly during installation.
The utility model content
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of flatness is good, easy construction, the thermal losses of minimizing body of heater and can prevent the heating furnace brick plate of the outside slippage of brick.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of heating furnace brick plate, it is characterized in that this heating furnace brick plate comprises brick plate body and bracing frame, be affiliated on bracing frame the rear end of brick plate body, bracing frame is connected with the furnace shell plate of heating furnace, and the front portion of brick plate body is provided with the fixing flange of building the refractory brick on pop-jump plate body.
The front portion of described brick plate body is provided with the flange that prevents the outside slippage of refractory brick.
Described bracing frame is a hollow structure, and the brick plate body can be affiliated in the top.
Between described brick plate body and stove coverboard the space is arranged, the hot pad of leptophragmata can be set.
The top of bracing frame is connected with brick plate body bottom hung type.
The rear portion of described brick plate body can be provided with the hot pad of leptophragmata that outwards transmits by the metal brick plate with intercept heat.
Compared with prior art, the utlity model has following advantage:
(1) adopt mobilizable hung type structure, it is very convenient to construct, and also helps freely stretching of structure.
(2) flatness of brick plate is good, and brick plate can be assembled in advance in manufactory, can make adjacent brick plate that goodish flatness is arranged, if the furnace shell plate has out-of-flatness slightly at the scene, can regulate with shim liner at brick plate gripper shoe place.
(3) because brick plate does not directly contact with the furnace shell plate, and the brick plate support is designed to hollow, so it is few to pass through the heat output of metal brick plate, the furnace shell wall temperature is low, reduces the hot-spot at this place, the radiation loss of minimizing stove.
(4) brick plate adopts the founding materials of low nickel, has not only saved expensive nickel resources, reduces capital expenditure; And casting brick plate rigidity, intensity is better than the steel plate materials of the high chromium nickel of Cr25Ni20 commonly used, Cr25Ni12, and brick plate is also not yielding.
(5) casting brick plate front portion is provided with the flange that prevents the outside slippage of refractory brick, can fix base course firmly, to control furnace wall thickness size, the center of gravity that keeps furnace wall is in brick plate, prevent the furnace wall flare, keep the stability of furnace wall to play very crucial effect, facts have proved that the novel brick plate structure of this kind of employing is used for new design and the transformation of old stove furnace lining has obtained great success.
Description of drawings
Fig. 1 is the structural representation of brick plate in the Comparative Examples 1;
Fig. 2 is the structural representation of brick plate in the Comparative Examples 2;
Fig. 3 is a structural representation of the present utility model.
1 is that brick plate, 11 is the furnace shell plate for slotted-angle shelving, 4 for bolt, 3 for the supporting leg on the brick plate, 2 for flange, 13 bracing frames, 14 for brick plate body, 12 among the figure.
The specific embodiment
