Abstract
The invention discloses a heating furnace brick holding frame structure which comprises a brick holding plate, a brick pulling rod and a heating furnace wall plate. The brick pulling rod is in a strip-shaped structure. The cross-section of the strip-shaped structure is F-shaped. Two shorter sides parallel to each other of the F-shape cross section are connected with the heating furnace wall plate. The brick holding plate comprises a plate body and a support. A bending portion towards the reverse surface of the plate body is arranged on one edge of the plate body. The support is connected with the reverse surface of the plate body. The support is L-shaped. One side of the L-shaped support is connected with the plate body. The bending portion of the plate body is fastened on the longer side of the L-shaped support. The other side of the L-shaped support directs toward the bending portion and abuts against the heating furnace wall plate. Due to the structure of the heating furnace brick holding frame, the heating furnace brick holding frame structure can be manufactured in a casting mode and applied to various heating furnaces. In this way, novel alloy materials can be selected to use, and heat-resistant property of the heating furnace brick holding frame structure is improved.
Description
Technical field
The technical program relates to a kind of brick plate, relates in particular to a kind of novel casting formula heating furnace brick-supporting rack structure.
Background technology
Brick plate is parts 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 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.
Existing heating furnace supporting brick is commonly used mainly contains following two kinds of forms:
The first be brick plate directly and furnace shell plate welded structure, the brick plate of this kind form is because the plate face directly is welded on the furnace shell plate, and is larger by the heat of metallic plate unofficial biography; Because usually adopt long steel plate, adopt Welding Structure easily to deform again, use the expansion of plate also easily to cause the distortion of plate under high temperature.
The second is that brick plate is connected with the support bracket bolt that is welded in advance the furnace shell plate, and this kind structure adopts the shorter brick plate of lower support plate that welds in advance one by one, is connected on the slotted-angle shelving that welds with the furnace shell plate with bolt.Avoid so long Plate Welding 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 during installation, adjacent brick plate levelness is regulated difficulty to some extent.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the technical program proposes a kind of new heating furnace brick-supporting rack structure, and concrete technical scheme is as follows:
A kind of heating furnace brick-supporting rack structure comprises brick plate, draws brick bar and heating furnace wallboard;
The described brick bar that draws is strip structure, and the cross section of strip structure is the F type, two parallel being connected with the heating furnace wallboard than minor face of F type;
Described brick plate comprises plate body and support; An edge of described plate body is provided with the bending towards the plate body reverse side, and described support is connected to the plate body reverse side; Described support is L-type, and a limit of L-type support is connected on plate body;
The bent buckling of described plate body is on the longer sides of described F type; Bending is pointed on another limit of L-type support, props up the heating furnace wallboard.
Described bending is perpendicular to plane, plate body place.
That limit of described sensing bending extends to the bending inside edge.
Described support has 2.
Described brick plate comprises polylith, each brick plate side by side with draw the brick bar.
The place, outer of described plate body is provided with flange up.
Wait in use, bent buckling is drawn on the brick bar at strip, the L-type stent support is drawn on the brick bar at strip and is got final product.
The technical program is because of its design feature, can the casting method manufacturing, be applied to various heating furnaces, and so just can select the novel alloy material, improve its heat resistance, compared with prior art, the technical program has the following advantages:
(1) adopt mobilizable hung type structure, construct very convenient, also help the free-extension of structure.
(2) flatness of brick plate is good, and brick plate can be pre-assembled in manufactory, can make adjacent brick plate that goodish flatness is arranged, if the furnace shell plate slightly has out-of-flatness at the scene, also can be regulated easily.
(3) because brick plate does not directly contact with the furnace shell plate, and the brick plate support Design becomes hollow, therefore few by the heat output of metal brick plate, furnace shell wooden partition temperature is low, reduces the hot-spot at this place, reduces the radiation loss of stove.
(4) brick plate can adopt the founding materials of low nickel, and casting brick plate rigidity, intensity are good, and brick plate is not yielding.Should hang down the steel plate materials that the nickel founding materials can substitute the high chromium nickel of Cr25Ni20 commonly used, Cr25Ni12, not only save expensive nickel resources, reduce capital expenditure, also meet the economizing type Development Policy that country advocates
(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 controlling the furnace wall thickness size, keep the center of gravity of furnace wall in brick plate, prevent the furnace wall flare, keep the stability of furnace wall to play very crucial effect, facts have proved and adopt this kind Novel supporting brick plate structure all to obtain great success for new design and the transformation of old stove furnace lining.

Fig. 3 is heating furnace brick-supporting rack structural representation.
In figure, plate body 1, bending 2, support 3, bending inside edge 4, heating furnace wallboard a, draw brick bar b, brick plate c.
The specific embodiment
Below in conjunction with drawings and Examples, the technical program is described further.
A kind of heating furnace brick-supporting rack structure comprises brick plate, draws brick bar and heating furnace wallboard; The described brick bar that draws is strip structure, and the cross section of strip structure is the F type, two parallel being connected with the heating furnace wallboard than minor face of F type; Described brick plate comprises plate body and support; An edge of described plate body is provided with the bending towards the plate body reverse side, and described support is connected to the plate body reverse side; Described support is L-type, and a limit of L-type support is connected on plate body; The bent buckling of described plate body is on the longer sides of described F type; Bending is pointed on another limit of L-type support, props up the heating furnace wallboard.
Described bending is perpendicular to plane, plate body place.That limit of described sensing bending extends to the bending inside edge.Support described in this example has 2.Described brick plate comprises 4, each brick plate side by side with draw the brick bar.The place, outer of described plate body is provided with flange up.
