A kind of ceramic roller for tempered glass furnace and its manufacturing process

Abstract

The invention discloses a ceramic roller for a tempered glass furnace and a manufacturing process thereof, comprising the following steps: preparing materials: mullite, alumina, refractory clay, kaolin, zirconium silicate, talc, vanadium pentoxide, boron nitride and magnesium oxide; mixing the ball mill to obtain a mixture; spray-drying the mixture, adding water to the spray powder, stirring, and extruding after muddling to obtain a green body; It is sintered in a high-temperature shuttle kiln to obtain a blank; cylindrically ground to a specified size to obtain a ceramic roller for tempered glass kiln. The ceramic roller for tempered glass furnace prepared by the invention has high density, high strength and hardness, high heat resistance, creep resistance and thermal peeling resistance, long service life, simple production method and easy operation, and high economic benefit. , suitable for industrial production.

Description

technical field

[0001] The invention relates to the technical field of ceramic material processing, in particular to a ceramic roller for a tempered glass furnace and a manufacturing process thereof. Background technique

[0002] Roller kilns are widely used in building sanitary ceramics, glass and other industries due to their characteristics of small firing temperature difference, short firing cycle, high yield, low energy consumption and easy control. In the glass tempered roller kiln, the roller is the most critical refractory material, which plays the role of carrying and conveying products in the kiln. The strength and high-temperature mechanical properties of the roller determine the operating temperature and loading of the roller kiln. quantity. Ceramic rollers have increasingly become the first choice for roller kiln transmission and bearing due to their high softening temperature and high temperature strength. The biggest feature of the ceramic roller is high tem...
