Abstract
The utility model discloses a novel high-temperature tube furnace for sintering, which comprises a furnace body. A zirconium oxide furnace liner is mounted in the furnace body, aluminum oxide fiber heat-insulation cotton is filled between the furnace body and the zirconium oxide furnace liner, the zirconium oxide furnace liner consists of at least four plates which are spliced, an alundum tube penetrates through the middle of the zirconium oxide furnace liner, at least one pair of silicon-molybdenum rods is arranged in the zirconium oxide furnace liner, and the silicon-molybdenum rods are symmetrically distributed. According to the chemical stability and thermal stability of zirconium oxide, the zirconium oxide furnace liner used in the novel high-temperature tube furnace for sintering guarantees high intensity and abrasion degree of the furnace body. According to the design of arched top plates, the silicon-molybdenum rods and a zirconium oxide coating layer in the zirconium oxide furnace liner, the stability of operation of the tube type furnace is guaranteed, temperature in use of the tube type furnace is increased, and the service life thereof is prolonged.
Description
Technical field
The utility model relates to a kind of high temp sintering device, is specifically related to a kind of high temperature sintering tube furnace.
Background technology
At present, the problem that is used for the high temperature sintering tube furnace existence of ceramic post sintering on the market has: 1. what most tube furnace adopted is the polycrystalline mullite fibre material, the actual work temperature limit is 1600 ℃, and relative special cermacis and the material that needs higher temperature are just inapplicable.2. the high temperature operation life of existing high-temperature tubular sintering furnace is too short, for example occur the surface of burner hearth pull-up fall in addition cave in, normal behaviour in service such as Si-Mo rod crystallization, make that the average life span of the high-temperature tubular sintering furnace be used for the special ceramic material preparation is all very short, often brought unnecessary trouble to the user.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of new type high temperature sintering tube furnace that improves the maximum temperature and the high temperature operation life of high temperature sintering tube furnace is provided.
The utility model provides a kind of new type high temperature sintering tube furnace to comprise body of heater, and zirconia furnace lining body is installed in the body of heater, is filled with the alumina fibre heat-preservation cotton between described body of heater and the zirconia furnace lining body; Described zirconia furnace lining body is made of the plate assembly unit more than four or four, and the middle part penetrates alundum tube is set, and symmetry is evenly equipped with a pair of above Si-Mo rod in the described zirconia furnace lining body.
Preferably, zirconia furnace lining body bottom center is provided with the zirconia bracing frame.
Preferably, the top plate of described zirconia furnace lining body is an arch.
Preferably, be coated with zirconia coating on the described zirconia furnace lining body inwall.
The employed zirconia furnace lining of the utility model body has utilized zirconia chemical stability and heat endurance, has guaranteed the high strength and the high-temperature of body of heater.The layout design of arch top plate, Si-Mo rod and zirconia coating has guaranteed the tube furnace job stability in the zirconia furnace lining body, has improved serviceability temperature and service life thereof.
