Conclusions
Laboratory tests carried out showed that carbon monoxide at 500 ± 20°C destroys all types of refractories, regardless of their chemical and mineral composition with more or less substantial porosities. Destruction of the refractories occurs more rapidly the higher the porosity and the lower the degree of vitrification.
Since the main cause of destruction in refractory in the shaft of a blast furnace is the action of carbon monoxide, the shaft needs to be lined with gas-impermeable refractories. The apparent porosity of the high-density high-grog refractory for the shaft of glass furnaces should be not more than 5–7%. With this density the refractory is practically gas-impermeable, and therefore is not destroyed by carbon monoxide. The optimum content of alumina in high-grog refractories should be considered as 35–37%.
