The reaction sintering silicon carbide ceramic roofing tile holds buck
Technical field
The utility model relates to the fine ceramics product technique field, relates in particular to a kind of reaction sintering silicon carbide ceramic roofing tile and holds buck.
Background technology
Tunnel cave is building materials, pottery, the more modernized industrial kiln of fire-resistant commercial Application, is a kind of quantity-produced Thermal Equipment, also is the leading Thermal Equipment of current sintering roofing tile.The moulding of roofing tile exists than big-difference; Its stacking mode that burns till has the upright burning of individual layer usually, multilayer is upright burns and the multi-layer flat burning; Mostly employed kiln furnitures are that dichroite-mullite porous refractory slab, hollow refractory slab and U type hold traditional kiln furnitures such as buck, and still traditional kiln furnitures ubiquity body weight, energy consumption is high, the life-span is short, be prone to aging defective.
The utility model content
The utility model technical problem to be solved is: provide a kind of reaction sintering silicon carbide ceramic roofing tile to hold buck, and in light weight, be difficult for wearing out long service life.
For solving the problems of the technologies described above; The technical scheme of the utility model is: the reaction sintering silicon carbide ceramic roofing tile holds buck; Comprise the two dichroite-mullite gripper shoes that are oppositely arranged; Be provided with the reaction sintering silicon carbide ceramic support beam that is used for the support roofing tile between the described two dichroite-mullite gripper shoes; The two ends of said reaction sintering silicon carbide ceramic support beam are equipped with the groove that is used to limit said reaction sintering silicon carbide ceramic support beam position, and the shape of said groove and dichroite-mullite gripper shoe is suitable.
As a kind of improvement, said reaction sintering silicon carbide ceramic support beam have one run through said reaction sintering silicon carbide ceramic support beam through hole, said through hole is consistent with the bearing of trend of reaction sintering silicon carbide ceramic support beam.
Owing to adopted technique scheme; The beneficial effect of the utility model is: because the support beam adopts the reaction sintering silicon carbide ceramic material to process; Have high-temperature oxidation resistant, rupture strength height, good thermal shock, use characteristics such as indeformable for a long time, simultaneously, simplify the structure; What the design of groove made gripper shoe and support beam combines more firmly, has prolonged service life.
Because reaction sintering silicon carbide ceramic support beam adopts hollow structure, when the sintering roofing tile, can shorten sintering time, has improved product quality and production efficiency, has reduced the sintering cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of support beam in the utility model;
Among the figure, 1, the dichroite-mullite gripper shoe, 2, reaction sintering silicon carbide ceramic support beam, 21, through hole, 22, groove.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Shown in Fig. 1 and Fig. 2 are common; A kind of reaction sintering silicon carbide ceramic roofing tile holds buck; Comprise the two dichroite-mullite gripper shoes 1 that are oppositely arranged; Be provided with the reaction sintering silicon carbide ceramic support beam 2 that is used for the support roofing tile between the described two dichroite-mullite gripper shoes 1, the two ends of said reaction sintering silicon carbide ceramic support beam 2 are equipped with the groove 22 that is used to limit said reaction sintering silicon carbide ceramic support beam 2 positions, and said groove 22 is suitable with the shape of dichroite-mullite gripper shoe 1; Concrete, the length of groove 22 on the bearing of trend of reaction sintering silicon carbide ceramic support beam 2 is identical with dichroite-mullite gripper shoe 1 thickness.
Said reaction sintering silicon carbide ceramic support beam 2 adopts hollow structure; Be reaction sintering silicon carbide ceramic support beam 2 have one run through said reaction sintering silicon carbide ceramic support beam 2 through hole 21; Said through hole 21 is consistent with the bearing of trend of reaction sintering silicon carbide ceramic support beam 2, when the sintering roofing tile, can shorten sintering time; Improve product quality and production efficiency, reduced the sintering cost.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the utility model.
