Abstract
The utility model relates to a load bearing board for nitrogen kiln which comprises a silicon carbide layer; the upper surface and lower surface of the silicon carbide layer are provided with the isolation layer composed of an alumina layer or a mullite layer, which is characterized in that the upper surface of the isolation layer of the load bearing board is provided with a single-block zirconia layer, and the zirconia layer, the silicon carbide layer and the isolation layer are calcined as a whole. The load bearing board for nitrogen kiln has the following advantages: 1. The single-block zirconia layer and the load bearing board are simultaneously made through the one-time pressing and calcining, which avoids the manufacturing of the complicated and high cost zirconia board in the existing technology as well as avoids the expensive equipment investment in order to reduce the cost. 2. The zirconia layer and the load bearing board form a whole, the service life of which is same with the load bearing board and greatly saves the cost. 3. The zirconia layer and the load bearing board form a whole, which greatly simplifies the fussy operation of placing the manganese-zinc ferrite in the use process of placing the use of tedious and improves the production efficiency.
Description
[technical field]
The utility model relates to a kind of firing support plate for nitrogen kiln.
[background technology]
Soft magnetic manganese-zinc ferrite is the basic material of information industry, and along with the high speed development of information industry, the MnZn material has vast market, has also promoted the development of soft magnetism sintering oven (nitrogen kiln) with load bearing board simultaneously.
As shown in Figure 1, common nitrogen kiln load bearing board is to be made of silicon carbide layer 10 and aluminium oxide or mullite layer 20, when high value manganese-zinc ferrite sintering, impurity composition in aluminium oxide or the mullite can cause its crystallization, therefore need cover one deck zirconia plate 30 again and isolate on load bearing board.At present, load bearing board is to separate sintering with the zirconia plate, and the zirconia plate is a product of making fritter by high-temperature calcination more than 1650 ℃, during use, the zirconia plate of fritter is pieced together placing on the load bearing board, carries manganese-zinc ferrite again and fires in the nitrogen kiln.
Fire the zirconia plate separately, need finish the production of complexity, high energy consumption, expensive zirconia plate, so manufacturing cost is very high.In actual use, the zirconia plate often produces fracture because of crystal formation changes, and damages prior to load bearing board, causes the use cost height.In use, also need to put the zirconia plate, use very inconvenient.
[summary of the invention] the utility model is further improved the structure that has load bearing board now at the problems referred to above.
The purpose of this utility model provides and a kind of zirconia layer and load bearing board compacting sintering is one, and is easy to use, the firing support plate for nitrogen kiln that cost is low.
The purpose of this utility model is achieved in that
A kind of firing support plate for nitrogen kiln, include silicon carbide layer, upper and lower surface at silicon carbide layer is provided with the separation layer that is made of alumina layer or mullite layer, it is characterized in that being provided with the monoblock zirconia layer at the separation layer upper surface of load bearing board, described zirconia layer and silicon carbide layer and separation layer compacting calcining are as a whole.
Aforesaid a kind of firing support plate for nitrogen kiln is characterized in that zirconia layer thickness is greater than 1.5 millimeters.
Aforesaid a kind of firing support plate for nitrogen kiln is characterized in that described separation layer is an alumina layer.
Aforesaid a kind of firing support plate for nitrogen kiln is characterized in that described separation layer is the mullite layer.
Aforesaid a kind of firing support plate for nitrogen kiln is characterized in that described separation layer is mixed with mullite by aluminium oxide to form.
The beneficial effects of the utility model are: 1, monoblock zirconia layer and load bearing board are once suppressed, and burn with load bearing board altogether and make synchronously, have avoided the manufacturing of complicated, expensive zirconia plate in the prior art, have avoided expensive equipment input, have reduced cost.2 zirconia layers and load bearing board form integral body, and be synchronous service life with load bearing board, saved use cost greatly.3, zirconia layer and load bearing board form integral body, have simplified greatly and have put the loaded down with trivial details operation of manganese-zinc ferrite in the use, have improved production efficiency.
[description of drawings]
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Fig. 1 is the prior art structural representation;
Fig. 2 is this usefulness new structure schematic diagram.
[specific embodiment]
As shown in Figure 2, the utility model is a kind of firing support plate for nitrogen kiln, include silicon carbide layer 1, upper and lower surface at silicon carbide layer 1 is provided with the separation layer 2 that is made of alumina layer or mullite layer, wherein separation layer 2 upper surfaces at load bearing board are provided with monoblock zirconia layer 3, and described zirconia layer 3 is as a whole with silicon carbide layer 1 and separation layer 2 compacting calcinings.
The silicon carbide layer that the utility model adopted has excellent high-temperature intensity and heat endurance, has guaranteed that load bearing board has stronger loading capacity and service life; Separation layer has certain chemical inertness, and effect is good in common manganese-zinc ferrite sintering; Zirconia layer can guarantee can not produce crystallization when high value manganese-zinc ferrite sintering.
The utility model in use, only need once compacting, the load bearing board of the once sintered composite construction that makes, make zirconia layer and load bearing board form integral body, make the service life of zirconia layer and load bearing board synchronous, save use cost greatly, and simplified greatly and put the loaded down with trivial details operation of manganese-zinc ferrite in the use, improved production efficiency.
