Conclusions
Tar-bonded unfired type MDTBS-70 and MDTBS-75 parts produced by Chelyabinsk Metallurgical Combine were tested under the conditions of the South Ural Nickel Combine in nickel production converters. The life of the refractories in the tuyere belt and in the wall above the tuyeres was the same as for KhPT parts and the rate of wear was 3–5 mm/h.
The primary factor influencing the wear rate of the refractories is the chemical reaction of the calcium oxide and the dolomite with the high-iron slags.
