Embodiment 1

[0174] Production of ceramic rollers with a specification of ?60mm. According to the ratio required for the manufacture of ceramic rollers, weigh 100kg of ceramic roller raw materials and 2kg of carboxymethyl cellulose, and add them to a strong mixer and mix for about 3 to 8 minutes. After mixing evenly, add water and stir for 10 to 20 minutes. , to get mud. The mud material is granulated and smelted twice through a direct-push mud mixer, and the mud is smelted for the first time to obtain a mud bar with a diameter of 6mm. The mud bars obtained by the first mud refining are put into a direct-push mud mixer for the second mud refining to obtain mud bars with a diameter of 4mm. The mud strips that have undergone secondary mud refining are added to the vacuum silo of the direct-push extruder, the vacuum degree is drawn to -0.08MPa, the extrusion molding pressure is set to 1500~2000KN, and the extrusion molding speed is controlled at 18 m / minute. The shape of the mold at the d...

Abstract

The invention discloses a ceramic roller molding process. The molding process comprises the following steps carrying out pug milling on forearmed pug through a pugmill so as to obtain pug stripes; and carrying out extrusion molding on the pug stripes through a transductive plastic extruder so as to obtain a ceramic roller tube blank with an inner support. According to the invention, the molding process is rapid in molding speed, high in efficiency and low in loss; adopted equipment is simple in structure and convenient to maintain; and a manufactured ceramic roller is high in density, high in bending strength, large in load capacity and good in appearance regularity.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing ceramic rollers, in particular to a molding process of ceramic rollers. Background technique [0002] The ceramic roller rod is one of the key components in the ceramic roller kiln, which plays the role of bearing and transmission. At present, the production of ceramic rollers mainly adopts the vacuum spiral extrusion molding method. The ceramic rollers produced by the vacuum spiral extrusion molding process have low cost, but due to their small molding pressure, insufficient compact structure, and low strength, they are suitable for use in It is used in occasions that do not require high load bearing. The vacuum spiral extruded ceramic blank tube is placed directly on a grooved pallet for drying. This method is mature in technology and widely used by ceramic roller manufacturers at home and abroad. However, the ceramic blank tube produced by the vacuum spiral extrusion mol...
