Problems solved by technology

In addition, in the fields of daily use, sanitary ware, and magnetic materials, the high-temperature performance of the roller is higher, and the ordinary alumina ceramic roller is difficult to meet the requirements of such occasions, and most of the ordinary alumina ceramics are currently in use. Roller rod, the technology used in this kind of ceramic roller rod is the vacuum extrusion molding process. This process uses ball milling, repeated spiral extrusion mud refining after press filtration, and then vacuum spiral extrusion molding.
This process repeatedly uses a screw extrusion device, which has a complex structure. When the cera

Abstract

The invention discloses a preparation process of a ceramic roller rod. The preparation process comprises the following steps of: atomizing and prilling on primarily-treated slurry; adding a binder, mixing, then adding water, and mixing in a into pug into a powerful mixer, wherein the water content of the pug is 10-18%; refining the pug through a direct pushing-type pug refining machine, and obtaining pug stripes; enabling the pug stripes to conduct extrusion molding through a direct pushing-type plastic extruder, and obtaining ceramic roller rod blank tubes provided with inner supports; conducting vertical type drying treatment on the ceramic roller rod blank tubes; conducting isostatic cool pressing process treatment on the ceramic roller rod blank tubes at the pressure of 60-300Mpa; and removing the inner supports of the ceramic roller rod blank tubes, putting the ceramic roller rod blank tubes into a kiln, and burning by a hanging and burning mode at the temperature of 1200-1800 DEG C. By means of preparation process, the prepared ceramic roller rod is high in density, high in flexure strength, big in load capacity and good in appearance regulation degree.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing ceramic rollers, in particular to a preparation process of ceramic rollers. Background technique [0002] As one of the key accessories of the roller kiln, the ceramic roller mainly plays the role of transmission and load bearing. At present, the roller kiln is developing in the direction of ultra-wide and ultra-long, which puts forward higher requirements for the load-bearing and high-temperature performance of ceramic roller rods. In addition, in the fields of daily use, sanitary ware, and magnetic materials, the high-temperature performance of the roller is higher, and the ordinary alumina ceramic roller is difficult to meet the requirements of such occasions, and most of the ordinary alumina ceramics are currently in use. Roller rod, the technology used in this kind of ceramic roller rod is vacuum extrusion molding process. This technology uses ball milling, repeated spir...
