Abstract
The invention discloses one kind to have the anti-alkali corrosion stove roof plate of heat exchange function large scale, cuboid plate body including being in interlayer structure, it is silicon carbide layer inside plate body, the compound alkali resistant layer of silicon carbide layer outer cladding, the plate body is equipped with several through-holes by the side grown and height forms.The present invention, by changing the structure of kiln top plate, facilitates kiln construction and repair, extends the service life of furnace roof, improve the utilization rate of kiln compared with traditional technology.
Description
Technical field
The invention belongs to fire resisting material fields, and in particular to one kind has the anti-alkali corrosion furnace roof of heat exchange function large scale
Plate.
Background technology
Lithium battery is the new generation of green high-energy battery of performance brilliance, is now widely used for consumer electronics, new energy
The fields such as automobile and aerospace industry.Positive electrode occupies core status in lithium battery, mainly including cobalt acid lithium, LiMn2O4,
LiFePO4 etc., anode material of lithium battery most domestic is roasted using high temperature kiln, since anode material of lithium battery is used
Raw material can decompose generate penetrating power and the strong lithia of reactivity erodes kiln body in the synthesis process, kiln top is easy
The problems such as peeling, dusting occurs.In order to improve the heat utilization efficiency of kiln, energy consumption is reduced, in the relatively low region of kiln temperature
It generally requires and exchanges heat, general kiln top is using stainless heat exchanger at present, and highly basic is to the seriously corroded shadow of stainless heat exchanger
The service life to kiln is rung, research and development corrosion resistance is good, and the stove roof plate with heat exchange function is for extending high temperature kiln
Service life has ten important roles.
Invention content
Goal of the invention：In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to it provides a kind of with the big ruler of heat exchange function
Very little anti-alkali corrosion stove roof plate.
Technical solution：In order to reach foregoing invention purpose, what the present invention was specifically performed by：One kind has heat exchange work(
Can the anti-alkali corrosion stove roof plate of large scale, the cuboid plate body including being in interlayer structure is silicon carbide layer inside plate body, the carbon
The compound alkali resistant layer of SiClx layer outer cladding, the plate body are equipped with several through-holes by the side grown and height forms.
Wherein, the composite bed that the compound alkali resistant layer is made of zirconium oxide, aluminium oxide, calcium oxide arbitrary proportion.
Further, the center of the through-hole is located on the center line in lateral length direction.
Wherein, the number of the through-hole is 5 ~ 20, preferably 8.
Wherein, the spacing between the adjacent through-holes is equal.
Further, a diameter of 15 ~ 150mm of the through-hole, preferably 70mm.
Further, the length of the plate body is 1000 ~ 2000mm, and width is 300 ~ 800mm, is highly 30 ~ 200mm,
Preferably, length 1800mm, width 620mm are highly 90mm.
Main innovation of the present invention is at three aspects：Firstth, the corrosion of anti-highly basic, plate body surface layer are the compound anti-of layer
Base material has good resistance to corrosion in heat-exchange temperature region；Secondth, plate body internal layer is the silicon carbide for having high heat conductance
Material forms, and has preferable heat transfer effect, and several through-holes is set further according to heat transfer requirements, improves ventilation rate；Third, plate body are
Integral structure convenient for the replacement and construction of kiln top, improves production efficiency.
Advantageous effect：The present invention, by changing the structure of kiln top plate, facilitates kiln construction compared with traditional technology
And repair, the service life of furnace roof is extended, improves the utilization rate of kiln.
