<p><P>PROBLEM TO BE SOLVED: To provide a structure, machine or facilities for handling and carrying a fine-grained iron source, particularly a vessel or the like with less adherence of the fine-grained iron to the inner face of a loading chamber, and having favorable carrying operation efficiency as well as high safety, and to provide a dump truck provided therewith. <P>SOLUTION: There is provided a member used for carrying the fine-grained iron source such as various dusts and sludge which generate in an ironmaking or steelmaking process and contain based on the total weight, 50-95 wt.% in the sum of metal iron of >0 to≤20%, FeO of >0 to≤50% and Fe<SB POS="POST">2</SB>O<SB POS="POST">3</SB>of≥10 to≤80%, and the balance of inevitable impurities. The member is made of a steel including, by mass,≤0.1% C, 0.01 to 3.0% Si, 0.1 to≤3% Mn,≤0.03% P,≤0.01% S, 3 to 8% Cr, 0.1 to 5% Al,≤0.02% N, and the balance Fe with inevitable impurities. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
