Advantages of two-component concretes, where in addition to refractory aggregate, the second component is an orthophosphoric acid based chemical binder are a shorter time for putting the lining into operation.
In turn, these two-component concretes have a number of significant drawbacks, the main of which are the phosphoric acid and its water-soluble salts impact on the human body, as well as on the environment both in the course of working with these components and in the case of containers disposal in which this acid is supplied together with the refractory aggregate.
Another drawback the consumers should pay attention to is titanium and silicon oxides presence in the composition. During long-term contact with liquid aluminum, these two components of the filler are reduced to metal with subsequent secondary oxidation, which leads to the working layer of the lining destruction and an increase of harmful non-metallic inclusions in the aluminum melt.
In addition, the concrete on a chemical binder drying and heating mode requires very strict adherence to the heat treatment schedule and, in fact, averages no more than 70 degrees per hour.
We have developed SBS SOLUT Cast 85 – a special type of refractory concrete resistant both to non-ferrous and ferrous metals melts and to liquid slags formed in the process of metal production. This concrete has all the positive qualities of both two-component concretes on a chemical binder and concretes on a hydraulic binder.
