Cracking and disrepair phenomenon, cause the service life of furnace roof low, and use cost is high, thermal conductivity is high, influences the heat insulation effect of furnace body, is unfavorable for
Scale mass production uses.
Utility model content
The purpose of the utility model is to overcome current furnace top insulation layers to crack and break easily caused by material heat expansion
It is high to damage phenomenon, thermal conductivity, the bad problem of heat insulation effect, and a kind of metal molybdenum smelting furnace closure insulation is provided, the metal molybdenum
Smelting furnace closure insulation has good thermal resistance performance, using the different radian shapes being attached by convex concave snap fastener
Bulk splice and combine as taper entirety furnace roof, decomposed thermal expansion caused by thermal stress, improve reuse the service life.
The utility model is realized in this way：A kind of metal molybdenum smelting furnace closure insulation, the insulating layer ontology are whole
Tapered shape, insulating layer ontology are spliced by connector, and the end face of two neighboring connector is connected with each other, the connector by
The hollow ball composition to contact with each other.
The angle of inclination of above-mentioned metal molybdenum smelting furnace closure insulation, the insulating layer body outer wall is 5-15 degree, is protected
Warm layer inner body wall angle of inclination is 15-25 degree.
Above-mentioned metal molybdenum smelting furnace closure insulation, the insulating layer body are disposed with 1-6 outward along radial direction
A ring layer, inner face and the outer end face of each ring layer are both provided with step, and two neighboring ring layer is overlapped by step activity.
The contact surface of above-mentioned metal molybdenum smelting furnace closure insulation, two steps to contact with each other is horizontal plane.
Above-mentioned metal molybdenum smelting furnace closure insulation, each ring layer include 4-6 connector, the connector of same ring layer
Side be both provided with step, two neighboring connector is overlapped by step activity.
Above-mentioned metal molybdenum smelting furnace closure insulation, the hollow ball are Bubble zirconia body.
The utility model has the following advantages that：The metal molybdenum smelting furnace closure insulation of the utility model, by furnace roof portion
Structure combined with the heat-insulating property of heating furnace, using the structure being integrally conical after assembly, insulating layer is by several hollow balls
The connector formed after compacting is mutually assembled, makes it have good thermal resistance performance, disclosure satisfy that the good heat preservation of furnace body
Performance；Meanwhile it being spliced and combined using the bulk for the different radian shapes being attached by convex concave snap fastener whole as taper
Body furnace roof has decomposed thermal stress caused by thermal expansion, improves and reuses the service life, reduces heating furnace and uses ceramic thermal insulation stove
Overall cost problem when top.

Fig. 2 is the sectional view of connector；
Fig. 3 is the sectional view of same ring layer connector；
In figure：1- connectors, 2- outer walls, 3- inner walls, 4- steps, 5- contact surfaces.
Specific implementation mode
With reference to specific embodiment, the utility model will be further described.
Embodiment 1：A kind of metal molybdenum smelting furnace closure insulation, the insulating layer ontology are integrally conical shape, insulating layer
The angle of inclination of body outer wall 2 is 15 °, and 3 angle of inclination of insulating layer inner body wall is 20 °, and insulating layer body is outside along radial direction
6 ring layers are disposed with, inner face and the outer end face of each ring layer are both provided with step, and two neighboring ring layer passes through step 4
Activity overlap joint, each ring layer include 6 connectors, and the side of the connector 1 of same ring layer is both provided with step, two neighboring company
Junctor 1 is overlapped by step activity, that is, the left-right and front-back of connector contact surface be respectively male-female assembly step
4, the contact surface of two steps 4 to contact with each other is horizontal plane, and because of the taper that is designed as of this furnace top insulation layer, all connectors 1 are equal
After forming complete furnace top insulation layer, have each other after being overlapped by convex-concave for the arc blocks of certain radian
The condition for having interconnection and stress is integrally formed because gravity guides, using assembled by concave-convex step overlapped connector 1
Be combined into taper entirety furnace roof, thermal stress caused by thermal expansion can be decomposed, avoid caused by material heat expansion cracking and
Disrepair phenomenon improves and reuses the service life；The connector 1 is made of the hollow ball to contact with each other, the hollow ball
Body is the hollow ball of 0.2-0.5 mm dias, and in 0.1-0.3 millimeters, hollow ball is compressed into as even the wall thickness of hollow ball
Junctor, the hollow ball are Bubble zirconia body, the thin wall type Bubble zirconia of hollow shape, and thermal conductivity compares oxygen
Changing zirconium powder sand combination has the characteristics that heat insulation effect is more preferable, thermal conductivity is lower, can substantially reduce the thermal conductivity of insulating layer, into
And the turnover rate of heat is reduced, thermal conductivity is the 40% of zirconium oxide flour sand combination, and the weight of whole furnace roof declines 60%, and repetition makes
With 4-5 times of life-span upgrading；The undesirable element for effectively avoiding original zirconium oxide flour sand combination furnace top insulation layer, greatly improves
The cost performance of ultrahigh temperature heating furnace furnace top insulation layer reduces the use cost of such ceramic cooktops insulating layer, saves electric energy consumption,
It is greatly saved resource, is suitable for mass, the ultrahigh temperature heating furnace of scale is used, pushed away to the industry of ultrahigh temperature heating furnace
Power is strong, highly practical.
