According to the present invention, the contact area between the upper and lower box type saggers can be greatly reduced, so that even if the number of times of use increases, an improved effect of not being strongly bonded to each other can be obtained, and an improved effect of achieving a stable automated process can be obtained. .
Description
The present invention is a multi-stage loading for firing the powder of ferrite powder (ferrite powder), metal oxide and magnetic material raw materials, and cathode active materials (LCO, LMO, LNO, NMC, LFP, etc.) in lithium ion batteries. It relates to a box-shaped sagger for more specifically, the shape of the lower box-shaped sagger part contacted with the box-shaped sagger at the top during multi-stage loading is formed in a curved line to greatly reduce the contact area, so that it is not strongly joined between the stacked saggers. At the same time, the material of the upper surface of the box-shaped sagger which is in contact with the lower box-shaped sagger is formed of a material that suppresses the infiltration of the oxide component generated from the powder. It relates to a box-type sagger for loading.
Generally, powders such as ferrite powder (ferrite powder), which are metal oxides and magnetic materials, and cathode active materials (LCO, LMO, LNO, NMC, LFP) of lithium ion secondary batteries are required to be fired at a high temperature in an electric furnace. .
The box-type sagger used for the firing of powder refers to a firing aid that maximizes the loading of the powder and has the required electrical characteristics when the powder is put into an electric furnace and fired.
However, such conventional box-shaped saggers are made of a mixture of alumina, mullite, magnesia, refractory clay, and the like, and the combination ratio thereof may vary slightly depending on the application.
The conventional box-type sagger contains powder in the inside, and when the firing operation is performed inside the electric furnace, sublimated components, such as Li oxide or Mn oxide, generated in the powder infiltrate into the surface of the box-type sagger, and the number of times of use increases. As the flying amount increases, the amount of infiltration increases, and a phenomenon in which the contact points of the box-shaped saggers stacked on the upper and lower stages are bonded to each other occurs.
Such a bonding phenomenon between the upper and lower box-shaped saggers is weakly formed at the beginning of use, but as the number of times of use increases, the bonding strength becomes stronger and does not fall to the extent of light impact. Therefore, there is an unreasonable situation in the automated process, such as the need to arrange a separate personnel for removing the bonded box-shaped saggers in the automated process.
That is, the conventional box-
Such a conventional box-
The surface contact of such a planar 32 structure increases the contact area between the box-
The present invention was developed in order to solve the conventional problems as described above, the object of the present invention is to make the shape of the box-shaped sagger of the bottom contacting with the box-shaped sagger at the top when the multi-stage stacking of the box-shaped sagger, the line contact in the prior art Compared to the present invention, the present invention provides a multi-stage stacking box-type sagger, which is improved so as not to be strongly bonded to upper and lower contact areas by greatly reducing the contact area.
Another object of the present invention is a phenomenon in which the material of the upper surface of the box-shaped sagger in contact with the lower box-shaped sagger is bonded to each other even when used for a long time by using a material that suppresses the infiltration of the oxide component generated from the powder. It is to provide an improved multi-stage stacking box type sagger to achieve a stable automation process by drastically improving.
In order to achieve the above object, the present invention, in the multi-stage stacking box type sagger for firing the powder in the furnace (Kiln),
A main body formed of a box-shaped structure having a concave space for containing powder formed on an upper surface thereof, and a body having sidewalls formed on four sides; And
And a support jaw protruding upward from the four corners of the side walls of the main body to support the lower surface of the main body of the other box-shaped sagger located at the upper side of the main body. It is to provide a multi-stage stacking box-type sagger minimizing the contact area by holding the lower body of the other box-shaped sagger located in the line contact.
And, the present invention is preferably a multi-stage supporting the lower surface of the main body of the other box-shaped saggers formed in an arc shape having a peak having the highest peak in the center of the cross-section thereof in line contact To provide a boxed sagger for loading.
In addition, the present invention preferably the main body is a multi-stage stacking box-type sagger attached to the bottom plate of the bottom surface in contact with the other box-shaped sagger at the bottom of each of the bottom plate of the material to suppress the infiltration of the oxide component generated in the powder. In providing.
And, the present invention is preferably to provide a multi-stage stacking box-type sagger made of a compound material containing 73 ~ 95% Al 2 O 3 .
Multi-stage stacking box-shaped sagger according to the present invention, respectively, protruding from the four corners of the main body to the upper side of the other box-shaped saggers supporting the lower surface of the main body of the other box-shaped sagger located on the upper side The structure minimized the contact area by supporting the lower surface of the main body in line contact.
Therefore, the present invention can significantly reduce the contact area between the upper and lower box-shaped saggers compared to the prior art, thereby obtaining an improved effect of not being strongly bonded to each other even if the number of times of use increases.
In addition, the multi-stage stacking box type sagger according to the present invention is a sublimated oxide component, such as Li oxide or Mn oxide, generated from the powder at the top of the box type sagger bottom plate contacting the base of the box shaped sagger at the bottom. Al 2 O 3 materials which suppress infiltration such as these are used. Therefore, according to the present invention, it is possible to achieve an improved effect of achieving a stable automated process by drastically improving the phenomenon of mutual bonding even when used for a long time many times.
