摘要

Set of support to support the mechanism of retention of regeneration heat in a stream of hot air furnace, furnace hot air current with the set of support, method for producing hot air using the furnace hot air current.The present invention relates to a set of support for apaiar a mechanism for retention of regeneration heat in a furnace hot air current for a blast furnace, which comprises a support rack to support the mechanism of retention and support columns for supporting the support rack In the set consists of a material of cast iron.In the material of cast iron consists of a ferritic matrix and a dispersion of particles of graphite, in which shape of graphite particles is substantially vermicular or nodular.
