The Australian Pilbara blend lump ore, which entered the Chinese market in 2007, is a
special blending ore. To master its behavior and effect in a BF adequately, the
metallurgical properties and high temperature reactivity of the Pilbara blend lump ore and
six other kinds of lump ore were researched. The reasonable proportion and mixing pattern
of the Pilbara blend lump ore was studied by carrying out softening and dropping property
tests, and this provides technological support for practical production.
