Lithium battery high-temperature corrosion resistance laminar saggar and preparation method thereof

Abstract: The invention relates to a lithium battery high-temperature corrosion resistance laminar saggar and a preparation method thereof The lithium battery high-temperature corrosion resistance laminar saggar is of an integrated structure mainly formed by a saggar wall and a saggar bottom face, and is characterized in that the saggar bottom face comprises a saggar base layer, a middle layer and a surface layer; the middle layer is located between the base layer and the surface layer; the saggar base layer is made of, by mass, 60-70% of cordierite, 20-30% of mullite and 1-10% of micro powder; the micro powder is one of andalusite and silllimanite or a mixture of the andalusite and the silllimanite by any ratio; the surface layer is made of MgO or ZrO2 or BeO; the middle transition layer is made of forsterite or zirconite or BeSiO3; and the saggar base layer, the middle layer and the surface layer are totally pressed through a dry pressing forming process to form a green body, reaction and sintering are conducted under the air atmosphere at a high temperature, and the lithium battery high-temperature corrosion resistance laminar saggar is obtained The saggar prepared by the method has the good thermal stability and erosion resistance

Saggar for firing active material of lithium secondary battery, and method for manufacturing active material using same

Abstract: The present invention relates to a saggar for firing an active material of a secondary battery, a method for manufacturing the saggar, and a method for firing the active material The saggar for firing an active material of a secondary battery according to the present invention has a coating layer formed on a bottom surface or a wall surface thereof so as to collect carbon dioxide By means of the coating layer, the concentration of the carbon dioxide in the saggar can be lowered by collecting the carbon dioxide that is a by-product resulting from a firing reaction, thereby enabling a reduction in the amount of remaining lithium in the active material The saggar of the present invention provides the saggar for firing an active material of a secondary battery, wherein the saggar has at least one through hole in the bottom surface, or the bottom surface and wall surfaces thereof so as to communicate a gas

Saggar and method for producing abrasive material through saggar

Abstract: The invention provides a saggar. The saggar is provided with a saggar base (1) and a saggar wall (2), wherein the saggar base (1) is provided with an upward groove, two or more air holes (3) are uniformly formed in the top of the saggar wall (2), and therefore the ability of the saggar to resist deformation at high temperature is improved, and the heat conduction and air permeation performance of material in the saggar is improved through the structure. The invention further provides a method for producing abrasive material through the saggar. The method comprises the steps of loading the abrasive material into the saggar, stacking the saggar on a kiln car for high-temperature calcination, cooling the abrasive material to the indoor temperature and then obtaining finished products of the abrasive material. The method has the advantages that the process is simple, the energy consumption is small, and the strength and the machinability of the abrasive material are improved.

Saggar for kiln sintering

Abstract: The invention provides a saggar for kiln sintering. The saggar is characterized in that two or more cross beams are arranged at the bottom of the saggar. According to the saggar for the kiln sintering, in a sintering process, the contact area between the cross beams and a blank can be reduced to the greatest extent due to arc parts of the cross beams, so that the deformation of the blank is reduced to the greatest extent. During sintering, the periphery of the blank can be heated, and the heating is uniform, so that the deformation caused by non-uniform heating is avoided. In addition, compared with the traditional technology, energy wasted when ceramic powder is heated is saved.

Saggar for firing active material of lithium secondary battery, and method for manufacturing active material using same

Abstract: The present invention relates to a saggar for firing an active material of a secondary battery, a method for manufacturing the saggar, and a method for firing the active material. The saggar for firing an active material of a secondary battery according to the present invention has a coating layer formed on a bottom surface or a wall surface thereof so as to collect carbon dioxide. By means of the coating layer, the concentration of the carbon dioxide in the saggar can be lowered by collecting the carbon dioxide that is a by-product resulting from a firing reaction, thereby enabling a reduction in the amount of remaining lithium in the active material. The saggar of the present invention provides the saggar for firing an active material of a secondary battery, wherein the saggar has at least one through hole in the bottom surface, or the bottom surface and wall surfaces thereof so as to communicate a gas.

Calcining method for improving quality of extra-large round graphite

Abstract: The invention discloses a calcining method for improving quality of extra-large round graphite. The calcining method includes: according to size of a special-carbon big circle product, making a saggar moderate in size; placing a special-carbon big circle blank in the saggar; charging filling into the saggar; placing the whole big circle blank in a calcining furnace for calcining. The saggar comprises a saggar body, two handles are arranged on each of two end faces of the saggar body and welded with the corresponding end face of the saggar body, a groove used for containing the big circle product and the filling is formed in the inner side of the saggar body, two side faces of the groove are circular-arc faces, and temperature differences between upper and lower and between front and rear of the big circle blank placed in the saggar are less than 15 DEG C. the saggar body is utilized to contain the big circle product and the filling, so that the filling can be effectively prevented from descending and the big circle product in the saggar can be ensured to be covered with the filling completely; due to small temperature differences, the filling is avoided sinking when the product is in the process of thermal polycondensation.

Automatic conveying device for roller kiln

Abstract: The invention provides an automatic conveying device for a roller kiln. The automatic conveying device comprises a saggar lifting assembly, a saggar transfer lifting assembly, a loading trolley and a kiln opening roller table. The kiln opening roller table is located at a kiln opening or the tail of the roller kiln. The loading trolley is used for carrying load bearing plates and saggars. The saggar transfer lifting assembly is used for being matched with the loading trolley, receiving the load bearing plates and the saggars from the loading trolley or sending the load bearing plates and the saggars to the loading trolley and conducting lifting and transferring motion. An automatic feeding system is arranged on the saggar transfer lifting assembly. The saggar transfer lifting assembly is located between the saggar lifting assembly and the kiln opening roller table to complete transferring and receiving cooperation of the load bearing plates and the saggars.
