Novaref
Refractory rollers for ceramic and automotive industries
The company
Novaref is an Italian company founded in the 1980s in Colognola ai Colli (VR). It produces and markets refractory rollers mainly intended for the ceramic and automotive sectors.
The rollers are installed inside the tunnel kilns allowing the linear advancement of the tiles during the firing phase; over the years, thanks to the experience gained, Novaref has become an industry leader and synonymous of high quality.
Novaref, through its commercial network supported by agents, exports all over the world serving the major international producers; Novaref is also a partner of large plant engineers operating in the ceramic sector.
In Spain we are present with a subsidiary; in the USA we have a distribution warehouse.
The production plant in Colognola ai Colli covers an area of 25,500 m2 of which 13,700 are covered, is equipped with 3 automated extrusion lines, 5 kilns, one of which with a robotic loading and unloading system for rollers of significant dimensions and weights and a new advanced workstation.
Branded Novaref products can resist thermal changes over long periods of time. Moreover, they can perform without reacting chemically to the other materials with which they are in contact. The rollers require special processing to maintain high quality standards and not break during the heavy stresses to which they are being subjected.
The development of ceramic is characterized by:
- Increase of ceramic roller dimensions
- Increase of the product weight due to oversized thickness
- New laminated products
- Higher firing temperatures, especially for porcelain tile.
The subsequent increase of thermomechanical stress has highlighted the need of ever increasing dimensions and higher ceramic roller grades.
Novaref suggests the following ceramic rollers:
Nova HD – High durability and resistance to deformation
Nova FX – Nova HF-XP Extremely high temperature and/or heavy loading
Nova HF – Nova HF-CR – Nova VHR Firing zone for floor and wall tiles
Nova SIX – Nova 421 Preheating and/or colling zone for floor and wall tiles
For the rapid cooling zone are also available our grades: Nova SiCar – Nova ST
ZMS-MULLITE GRIT is a first quality refractory material, composed of mullite and corundum crystals.
It is produced by sintering a compound of alumina and clay in a shuttle kiln at around 1500° C.
It gives high resistance to thermal shock and chemical corrosion at elevated temperature, low-reversibility thermal expansion and excellent thermal stability.
ZMS-MULLITE GRIT is used in the refractory and iron/steel industries as well as in the ramming mixed and refractory mortars.
