The excellent quality of the ferrosilicon anodes is ensured by the manufacturing with induction melting procedure in a semi-automatic plant which precludes the possibility of metal contamination and guarantees the equal distribution of elements in the end-product.
The anodes are manufactured either by mould casting or by traditional sand casting procedures using strict regulations. The outstanding corrosion resistivity and other favourable characteristics are the result of the manufacturing procedure and this makes the ferrosilicon anodes internationally recognized for corrosion protection systems. From 2004 we are using FeSi anodes, produced by casting technology of CHILLMOULD. This technology succeed a perfect metal grain structure, as you can see on the picture above.
The manufacturing of ferrosilicon anodes is carried out by the observation of the following internationally respected regulations for corrosion resistant silicon alloy cast irons: BS1591 1975, ASTMA518-80
Ferrosilicon materials have dense, homogenous properties that ensure the equal distribution of anode characteristics along the total length. The end-product has low elongation properties and therefore must be carefully treated and can not be exposed to mechanical or thermic extremes.
