Abstract
The method based on Ω types rotary kiln and annular furnace combined sintering powder body material that the invention discloses a kind of, includes the following steps：1）, preheating dehydration carried out to advanced powder body material using atmosphere protection type continuous metal coating liner rotary kiln, it is spare；2）, heated up to advanced powder body material using atmosphere protection type continuous circular shape stove, sintering reaction；3）, pressure cooling carried out to advanced powder body material using the continuous composite ceramics liner rotary kiln of atmosphere protection type.Using the degree of purity of advanced powder body material produced by the invention, sintering uniformity higher, and energy consumption is kept low, and the thermal efficiency is high, it is more energy efficient, environmentally friendly, it is static combined with dynamic high-efficiency sintering, both it can guarantee that sintering temperature was uniform, also not ring formation, control climate is more succinct, conveniently, nonmetallic contact can be met, the sintering requirement of deep-etching performance products, sintering process does not have to saggar, by the characteristic perfection of rotary kiln and annular furnace to conjunction.
Description
Technical field
The method based on Ω types rotary kiln and annular furnace combined sintering powder body material that the present invention relates to a kind of.
Background technology
Currently, advanced powder body material is mainly packed into sagger special by the method for the advanced powder body material of industrialized production at present
Interior feeding atmosphere protection type roller-way（Tunnel oven）Or pushed bat kiln carries out semi continuous production, belongs to static sintering method, is entirely burning
Material is stationary always during knot.Burning, raw burn or even the two easily occur for uneven heating simultaneous half-cooked
Phenomenon.Influence the charge/discharge capacity of material.
To solve the above-mentioned problems, existing specialized company successfully has developed the continuous composite ceramics liner of atmosphere protection type recently
Rotary kiln sintered technology, the sintering of advanced powder body material is carried out using this technology, and material is uniform with the rotation of rotary kiln staving
It is heated, dynamically travels forward, it can be achieved that dynamic high-efficiency is sintered.It compared to more static sintering, can substantially shorten sintering time, improve heat
Energy utilization ratio, sintering temperature is evenly.Powder product can be directly obtained, appearance structure is uniform, chemical property is outstanding, and has
Good consistency.But advanced powder is in the sintering process that heats up（Especially 350~600 DEG C）, the sticky meeting of powder body material
It is significantly increased, in addition the adherent effect of rotary kiln, when this process occurs, material is easy to just be sticked on the ceramic liner of rotary kiln,
And it is not easy to fall reality.Same burning, raw burn or even the simultaneous half-cooked phenomenon of the two, the new problem of easily occurring also is difficult to overcome.
Invention content
It is a kind of based on Ω types rotary kiln and annular furnace combination purpose of the present invention is to provide in view of the defects existing in the prior art
The method for being sintered powder body material.
The present invention to achieve the above object, adopts the following technical scheme that：One kind is combined based on Ω types rotary kiln and annular furnace
The method for being sintered powder body material, includes the following steps：
1）, preheating dehydration carried out to advanced powder body material using atmosphere protection type continuous metal coating liner rotary kiln, it is standby
With；
2）, heated up to advanced powder body material using atmosphere protection type continuous circular shape stove, sintering reaction；
3）, pressure cooling carried out to advanced powder body material using the continuous composite ceramics liner rotary kiln of atmosphere protection type
Beneficial effects of the present invention：Using the degree of purity of advanced powder body material produced by the invention, sintering uniformity higher, and energy
Consumption is kept low, and the thermal efficiency is high, more energy efficient, environmentally friendly, static combined with dynamic high-efficiency sintering, both can guarantee sintering
Temperature is uniform, and also ring formation, control climate more succinctly, conveniently, can not meet nonmetallic contact, the burning of deep-etching performance products
Knot requires, and sintering process does not have to saggar, by the characteristic perfection of rotary kiln and annular furnace to conjunction.
Specific implementation mode
The method based on Ω types rotary kiln and annular furnace combined sintering powder body material that the present invention relates to a kind of, including following step
Suddenly：
1）, preheating dehydration carried out to advanced powder body material using atmosphere protection type continuous metal coating liner rotary kiln, it is standby
With；
2）, heated up to advanced powder body material using atmosphere protection type continuous circular shape stove, sintering reaction；
3）, pressure cooling carried out to advanced powder body material using the continuous composite ceramics liner rotary kiln of atmosphere protection type
Using the degree of purity of advanced powder body material produced by the invention, sintering uniformity higher, and energy consumption is kept low,
And the thermal efficiency is high, and it is more energy efficient, environmentally friendly, it is static combined with dynamic high-efficiency sintering, it both can guarantee that sintering temperature is uniform, did not tied also
Circle, control climate more succinctly, conveniently, can meet nonmetallic contact, the sintering requirement of deep-etching performance products, sintering process
Without saggar, by the characteristic perfection of rotary kiln and annular furnace to conjunction.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
