New Technology, New Refractories. Engineering-Economic Analysis

The heat resistance of refractories, expressed in hours, heats, etc., is determined by the performance characteristics of the refractory lining and the observance of operating conditions of a plant. Currently, the efficiency of using refractories is assessed in terms of production cost per ton of the end product. In determining the production cost of a refractory, it is necessary to take into account not only the net cost but also additional expenditures expressed in roubles (less frequently, in US dollars) per ton of product. Taking, as an example, the use of different refractory materials in the service of the outer lining of the branch inlet of a vacuum degasser, we carried out an engineering-economic analysis of the potential applicability of actual refractories to one or the other technology. Improving the actual technology of using refractory materials provides a way towards improving economical efficiency.
