Abstract: Blast furnace plant (1) and shutdown process for such a blast furnace plant (1). The blast furnace plant comprises a blast furnace (2) and a gas cleaning section (6) for cleaning gas from the blast furnace. Clean gas is released via a clean gas vent line (11) downstream of the gas cleaning section.

Abstract: A delivery device for delivering filler material into a blast furnace, comprising: a housing provided with a transition channel for the filler material which defines a first axis X; a chute for the filler material arranged underneath said transition channel; first actuating means, defining a respective second axis A parallel to the first axis X, to actuate a tilt of the chute with respect to the first axis X; second actuating means, defining a respective third axis B parallel to the first axis X, to actuate a rotation of the chute about said first axis X; a first annular body inside said housing and coaxial to the first axis X, adapted to translate along the first axis X by means of said first actuating means; a second annular body inside said housing and coaxial to said first axis X, adapted to translate along the first axis X being coupled to the first annular body and/or adapted to rotate about the first axis X by means of said second actuating means; a mechanism coupled to the second annular body and t

Abstract: Support assembly for supporting heat regeneration checker work in a hot blast stove for a blast furnace. The assembly includes a supporting grid for supporting the checker work, and supporting columns for supporting the supporting grid. The assembly includes a cast iron material. The cast iron material includes a ferritic matrix and a dispersion of graphite particles wherein the shape of the graphite particles is substantially vermicular or nodular.
