Conclusions The flame guncreting of basic refractories was studied on a rig, the base part of which was a model of a standard 130 ton oxygen converter. The highly refractory constituent of the guncrete body consisted of industrial magnesite powder obtained by fine grinding. The fuel was natural gas. A guncrete coating up to 100 mm thick was applied to the lining of the model. Specimens of guncrete coating consist of dense material having a finely crystalline structure (porosity up to 3%). The density of the guncrete coating depends mainly on the guncreting temperature. The existence of direct bonds between the grains of periclase is typical for the structure of guncrete coatings. Additions of iron oxides increase the number of grains coming into contact by means of a direct bond, while additions of calcium and silicon oxides reduce it.
