Description
Technical Field
The invention belongs to the field of high-temperature heat treatment electric furnace industry, and particularly relates to an inclined high-temperature rotary continuous heat treatment tubular furnace.
Background
In order to improve the heat treatment efficiency of materials, a continuous heat treatment furnace is generally used industrially. At present, an electric Furnace for continuous heat treatment operation is mainly a Belt Furnace (Belt Furnace), and the structure of the electric Furnace is characterized in that the electric Furnace comprises a gradient temperature rise and drop interval, so that the electric Furnace is large in size, large in occupied area, high in manufacturing cost, difficult to popularize and apply comprehensively, applicable temperature is generally below 1600 ℃, and in order to improve the applicable temperature, a gradient temperature zone needs to be further amplified, so that the structure is more complex and the size is larger. Although the belt furnace can realize continuous operation, the effect of material heat treatment uniformity is not as good as that of the rotary furnace. In the heat treatment stage, the rotation is beneficial to improving the uniformity of the material. At present, the commercial rotary tube furnace can improve the uniformity of material heat treatment, but is difficult to realize continuous heat treatment function, mainly stays in periodic operation, and the applicable temperature is basically not more than 1500 ℃.
For this reason, there is a related practitioner to develop a rotary furnace like a belt furnace, i.e., a tubular rotary continuous furnace, combining both advantages. The continuous rotary furnace reported in patent CN202582157U uses metal screw blade rods to convey materials to realize continuous operation function. U.S. cabert company has announced a continuous high temperature rotary tube furnace scheme, and patent WO099/67588, CN1312903A, regard high temperature alloy container as the boiler tube, the inner wall is equipped with the thread tooth, can drive the material to move, and then realize the function of feeding in and discharging in succession, this design scheme has selected high temperature alloy container for use, except that the cost is expensive, so a series of problems still exist: the heavy container causes easy loss of the bearing, the applicable temperature of the material is low, generally not more than 1700 ℃, the metal is easy to embrittle, the service life of the container is low, and the like. In order to reduce the manufacturing cost, high-temperature resistant non-metallic materials such as graphite, BN and the like are often adopted and can also be suitable for high temperature, the scheme of the rotary tube furnace of the American Centorr Vacuum Industries company can meet the use requirement of continuous operation at high temperature (more than or equal to 1600 ℃), and the equipment adopts the scheme similar to the thread-tooth furnace tube scheme in the structural design so as to realize continuous heat treatment.
In general, the common characteristics of the tubular rotary continuous furnace are that the material is driven to move forward by adopting a thread tooth transmission structure so as to complete feeding and discharging, the structural defects are that material residues are difficult to avoid, and the material is easy to be solidified on a furnace tube and difficult to remove after high-temperature treatment. If an inclined structure is adopted, the problem of material residue can be avoided. Although there are also commercial tiltable tube furnaces, there are structural limitations and continuous heat treatment operations have not been achieved. Therefore, based on the limitations of the prior art solutions, there is a need to provide a tilting rotary tube furnace with a new structure to realize the coexistence of no material residue, rotation and continuous operation.
