    摘要: The invention relates to a cored filler wire that includes an additive containing calcium silicate CaO.SiO
    2 , adapted for treating so-called resulphurized special steel. The invention also relates to a method for making resulphurized steel using the above cored filler wire. The method of the invention is particularly adapted for treating solid inclusions present in aluminium-containing steel baths. The method of the invention can be used for preventing desulphurisation before the treating of the solid inclusions.

    摘要: A wire for injecting into a steel melt in an injection direction, the wire comprising a metallic tubular shell enclosing a core, the core comprising calcium or a calcium containing compound, wherein the core also comprises a distribution enhancing compound for distributing the calcium or calcium containing compound in the steel melt in a direction substantially perpendicular to the injection direction wherein the distribution enhancing compound comprises a compound having a vapour pressure which is higher than the vapour pressure of calcium at liquid steel temperatures for obtaining a more homogeneous distribution of the calcium or calcium containing compound in the steel melt. The invention also relates to a process of treating a steel melt using said wire, the use of said wire and the resulting continuously cast steel product.

    摘要: With the object of effective utilization of a fine powder generated during comminution of a crude material for iron manufacture, a briquette (B1) is provided which comprises a porous brittle molded body (Z1) with a bulk specific gravity of 1.5 or more which is obtained by compression molding of a molding composition comprising a fine powder (MN) generated during comminution of a crude material for iron manufacture and a reinforcing portion (K1) for reinforcing the brittle molded body (Z1). Further, with the object of effective reuse of used alumina grinding stones, a briquette (B2) is provided which comprises a porous brittle molded body (Z2) obtained by compression molding of a molding composition comprising a comminuted powder of a used alumina grinding stone (A) and a cotton-like aggregate (M) comprising a grinding powder of a ferrous metal and a grinding liquid, and a reinforcing portion (K2) for reinforcing the brittle molded body (Z2).
