Description
[ technical field ] A method for producing a semiconductor device
The invention belongs to the technical field of high-temperature sintering kilns, and particularly relates to a rolling sagger push plate tunnel kiln and a sintering method.
[ background of the invention ]
The high-temperature sintering furnace is an important heating device commonly used in industry, and is widely applied to powder sintering or blank sintering of active metals, refractory metals and alloys thereof, ceramic materials and dissimilar materials. The conventional high-temperature sintering furnace can be mainly divided into a push plate kiln and a rotary furnace according to the structure.
Professionals who work in battery material preparation know that the sintering process of the novel battery material is an extremely important and complex generation process, and the novel battery material has specific and accurate requirements on physical conditions such as temperature (height, uniformity), atmosphere (oxygen content), atmospheric pressure, residence time and the like, and the materials are required to be continuously subjected to phase change along with the temperature condition in the process to generate certain coke discharge and exhaust, and a coke-gas mixture needs to be timely discharged from a material melt body, so the novel battery material has specific requirements on the geometric shape of a sagger, the sagger can safely and completely contain the materials, and the materials can be subjected to relative posture change in the sagger according to the requirements.
The shape of the push plate kiln is originally proposed by Japan, the main body of the push plate kiln is a section of tunnel type high-temperature kiln body, saggars containing materials to be sintered are sequentially queued to be pushed into the kiln body from the kiln head, and high-temperature sintering is carried out in the kiln for a plurality of times. The push plate kiln can ensure the precision of temperature control through the tunnel kiln body, but the push plate kiln cannot enable materials to be rolled and mixed uniformly when being heated, and cannot meet the requirements of material coke discharging and air exhausting.
The rotary furnace is firstly proposed by Germany, and mainly comprises a cylindrical furnace body capable of rotating along the axis, a spiral propelling mechanism is arranged in the furnace body, materials are fed from one end of the furnace body and then heated at high temperature by heaters arranged above and below the furnace body, the furnace body rotates, and the materials slowly roll in the furnace body, move to the other end and are discharged. However, the temperature control of the rotary furnace is difficult to achieve the general accuracy of the push plate kiln due to the limitation of shape. In addition, the furnace body of the rotary furnace has very high requirements on the processing technology, the uniformity of the wall thickness of the furnace body is difficult to master due to the large volume of the furnace body, the processing precision is difficult to achieve, the air tightness is difficult to control, and small furnace body fragments fall off to cause irreversible damage to the whole sintering process. Limited by the processing technology, the high-performance rotary furnace is difficult to manufacture in China at present. Although rotary furnace products exist abroad, the rotary furnace products are not sold to China due to strategic consideration, which greatly restricts the development of related fields of China.
[ summary of the invention ]
The invention aims to overcome the defects in the prior art and provide the rolling sagger push plate tunnel kiln, which can ensure uniform high-temperature heating, turnover of materials, coke discharge and exhaust, reduce the requirements on a furnace body processing process and meet the sintering requirements of related materials.
In order to realize the aim, the invention provides a rolling sagger push plate tunnel kiln, which is characterized in that: the sagger comprises a tunnel kiln body and at least 2 sagger push plate units, wherein each sagger push plate unit comprises a sagger and a push plate support, each push plate support comprises a push plate and a support, each sagger is provided with at least 1 revolving shaft, each sagger can rotate around the corresponding revolving shaft, each support supports the corresponding sagger to enable the corresponding revolving shaft to keep relatively static with the corresponding push plate support in a three-dimensional space, and each sagger can be driven by the corresponding push plate to horizontally move; the rolling sagger push plate tunnel kiln further comprises a driving mechanism for driving the sagger to rotate.
Preferably, the sagger comprises a sagger body and a cover plate, the sagger body is used as a vessel for containing sintering raw materials, and the cover plate is used for sealing the sagger body so that the raw materials cannot leak out. The shape of the sagger is generally cylindrical, but can be other shapes, such as drum-shaped or regular polygonal cylinder, as long as the cross section of the sagger perpendicular to the rotation axis is a centrosymmetric figure.
Preferably, the sagger body and the cover plate are made of materials resistant to high temperatures and to acids and bases, but the skilled person will be able to choose any possible material according to the needs of the sintering process, such as any metal, non-metal, synthetic material that meets the requirements of the state of the art; more preferably, the sagger body and the cover plate are made of ceramic.
In one embodiment, the driving mechanism comprises at least 1 circle of transmission gears arranged on the saggars and surrounding the revolving shaft, and at least 1 driving toothed belt arranged on the tunnel kiln body, and the transmission gears on two adjacent saggars are not meshed; when the sagger is positioned in the tunnel kiln body, the driving toothed belt is meshed with the transmission gear, and the sagger is driven by the driving toothed belt to rotate around the revolving shaft.
Further, the driving mechanism comprises at least 2 driving toothed belts, and the 2 driving toothed belts can be located in different temperature zones of the tunnel kiln body and can run at different speeds, so that the sagger can rotate at different rotating speeds in the different temperature zones, and the requirements of a more complex sintering process are met.
In another embodiment, the driving mechanism comprises at least 1 circle of transmission gears which are arranged on the saggars and encircle the revolving shaft, the transmission gears of two adjacent saggars are meshed, the driving mechanism further comprises a driving gear, the driving gear is meshed with the transmission gear on any one saggar, and the driving gear drives the saggars to rotate around the revolving shaft.

In another embodiment, the support comprises at least 2 rollers, the rollers are tangent with the outer surface of the sagger, the cross section of the contact part of the sagger and the rollers, which is vertical to the revolving shaft, is circular in outer contour, and the at least 2 rollers support the sagger so that the outer surface of the sagger is not contacted with the push plate. In fact, the roller may also be a gear, and the position where the sagger is matched with the roller may also be arranged in a gear ring structure, and in such an arrangement, the roller can also play a role in lifting the sagger and enabling the sagger to rotate around the fixed revolving shaft.
From the above-described relationship of the pusher supports to the saggars, it can be seen that the pivot axis is a geometrical feature of the saggars, and it is not necessary to form the saggars as a solid body (such as the support axis), and the saggars can still rotate around a relatively fixed axis (i.e. pivot axis) when they are supported by at least 2 rollers tangent to the support axis. The pusher carriage may be in many forms as long as the sagger and the pusher carriage can be moved into and out of the tunnel kiln together.
On the other hand, the invention also provides a material sintering method, which is characterized by applying the rolling sagger push plate tunnel kiln. Preferably, the method comprises the steps of: and putting materials into the saggars, pushing the saggar push plate units into the tunnel kiln body in a queue mode, heating the saggars in the tunnel kiln body, driving the saggars to rotate by the driving mechanism, and pushing the saggar push plate units out of the tunnel kiln body after sintering is finished.
