<p>It is disclosed a rotating chute for distribution of the charge in blast furnaces in which a first portion (2) defining an impact region of the feed material has a plurality of box-shaped modules (4) to retain part of the feed material and reduce problems connected with wear.</p><p><Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">A second portion (3) defining a sliding region for the feed material has a reinforced structure in section consisting of an outer load bearing shell (19), a first reinforcing shell (20) disposed internally of the preceding one, a second reinforcing shell (22) extending longitudinally as far as the impact region and finally a wear-resistant wall secured to the second reinforcing shell (22). The structure appears to be monolithic and cell-like and, due to an engagement system by mechanical fitting with subsequent welding, use of bolting operations can be avoided, the structure appearing mechanically more resistant.</p><p><Paragraphs id="pa03" num="0003" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">The conceived distributing chute further has a particular rear closing structure (10) and a protection body (18) disposed at the front to shield the chute plates from flames.
