Conclusions
Savinsk magnesite fired in rotary kilns can be used to obtain dense magnesite powder with a porosity of less than 10% (without reducing the furnace output and substantially increasing the firing temperature). The powder is suitable for producing magnesia refractories for high-duty purposes. On the basis of dense powder obtained from Savinsk magnesite periclase-spinel refractories were produced with relatively high working properties.
The wear of the products made from Savinsk magnesite in a roof of a 400-ton open hearth furnace is 22.7% less than in products made from Satkinsk magnesite. Subsequently it will be desirable to test products in a 600-ton open hearth furnace.
