[Sigma] Technology Without Water And Clay - And Special Refractories For Glass

Thanks to its own in-house special vibro-casting technology, SIGMA can manufacture "special huge size refractory blocks" for very wide working end superstructures and for large dog-house arches. The benefits to be obtained from these products include decrease in glassy phase, improvements in refractoriness under load and creep resistance. In this article the company provides some examples of these products, which do not involve the use of water or clay.
