Experience of using OOO Gruppa Magnezit refractory materials in the lining of acid converters in Russia and
the Ukraine is summarized briefly. Information is provided on the basis of results obtained in different metal
lurgical enterprises about the practice of using a set of measures promoting an increase in the operating life of
Steel production in converters using oxygen combined
with ladle finishing and pouring into a CBCM is developing
effectively in the direction of energy and resource saving
technology . The requirement for reducing specific expen-
diture with an increase in the volume of production of con-
verter steel gives rise to a constant trend towards increasing
converter lining life. For Russia and the Ukraine the impor-
tance of this problem emerges from the fact that the propor-
tion of steel produced in converters will increase within the
foreseeable future (Table 1).
OOO Gruppa Magnezit currently supplies refractories
for all converter production in Russia and the Ukraine (with
the exception of OAO MM Kim. Il’icha, Ukraine). Here the
maximum life is achieved for the lining of converters in
OAO MMK, OAO NLMK, OAO DMKD, OAO Alchevsk
Metallurgical Combine, OAO Enakievsk Metallurgical
Plant, OAO Mittal – Krivoi Rog, OAO MK im. Petrovskogo,
OAO ChMK; good results have also been obtained in both
workshops of OAO ZSMK, and in OAO NTMK.
The reason for the success of OOO Gruppa Magnezit is
in the combined approach to solving the problem of increas
ing the life of converter linings, starting with qualified engi
neering: development of a lining plan taking account of the
