Welding materials

The following materials are available for the repair, depending on the part of the furnace to be treated:
HWC-S-1, a silica based material, HWC-Al-1, an alumina based material, HWC-AZS-1, a material based on AZS.

In addition, for the glass industry we also use HWC-S-2, a welding material based on silica and used for the maintenance and repair of silica refractories.

HWC-AL-1

Ceramic welding material based on alumina, mainly used for nose rings in cement furnaces, cyclones and in the glass industry.
Al2O3 approx. 72%
SiO2 approx. 27%

HWC-AZS-1

Aluminium based AZS ceramic welding material, mostly used for aluminium furnaces and in the glass industry.
SiO2 approx. 38%
Al2O3 approx. 37%
ZrO2 approx. 20%

HWC-FC-1

Ceramic welding material based on fireclay, used in the coking and glass industries.
Al2O3 approx. 69%
SiO2 approx. 27%

HWC-S-1

Ceramic welding material based on fused silica, used in the coking and glass industries.
SiO2 approx. 94%

HWC-S-2

Material based on high purity fused silica, mainly used in the coking and glass industries.
SiO2 approx. 98%
