Alumina ceramic tube/pipe/rod/roller
  • Product Details

Product Introduction

Alumina ceramic roller  is kind of structural ceramic. The quartz ceramic roller is a key component in the glass horizontal tempering furnace, and is mainly used for carrying and transporting glass in the glass horizontal tempering furnace. The ceramic roller uses high-purity fused alumina as raw material, with high bulk density, high strength, low thermal expansion, good thermal shock stability, high dimensional accuracy, no deformation at high temperature, long service life, and no pollution to glass.

Alumina Ceramic Rollers for kilns used for firing wall tiles and wear-resistant bricks.

Alumina Ceramic Rollers for firing floor tiles, porcelain tiles.

Alumina Ceramic Ceramic Kilns Rollers for large and thick tiles, roof tiles, sanitary ware, and Magnetic Ceramics.

Key ComponentAL2O3
Working Temperatureup to 1400℃


1. The alumina ceramic roller surface is smooth, delicate, with small radial runout, and the processing accuracy is better than similar imported products, and it does not scratch the glass.

2. The steel head adopts anti-loosening sleeve structure design and assembly, long service life

3. It has the characteristics of high density, high strength, no deformation at high temperature, wear resistance and long service life.

4. High economic efficiency, can reduce the comprehensive cost of belt conveyor and reduce maintenance man-hours.
