Plates and Forms for the Refractory Industry
SGL Group manufactures a wide range of SIGRAFORM® products for the refractory industry.
When processed into plates and molds, our graphite products are used to manufacture refractory materials in complex geometric shapes to cater for furnace linings used in the iron and steel, glass, aluminium, concrete and ceramics industries, as well as shaping tools for these industries.
SIGRAFORM® carbon and graphite materials display the following key properties in practical use:
- High thermal shock resistance
- High mechanical strength and impact resistance
- Low hardness, hence easy and fast remachining
- Low wettability and low tendency to bond
- Excellent corrosion resistance
- High thermal stability
- Favorable porosity
