<p><P>PROBLEM TO BE SOLVED: To provide a method and structure for preventing abrasion of an inner wall surface of a curved pipe at a curved part of a piping for pneumatically dispatching various particles used as iron-making raw material in a pig iron manufacturing factory or a steel manufacturing factory of iron industry. <P>SOLUTION: By arranging magnets 3 throughout total arc length on an outer wall surface of a curved part 2 of a piping for pneumatically dispatching iron-making raw material particles 1 including magnetic particles 4, and the magnetic particles 4 are magnetically attached to the inner wall surface of the curved part 2. Alternatively, the magnetic particles 4 are magnetically attached to the inner wall surface of the curved part 2 by embedding magnets 3 throughout total arc length on the inner wall surface of the curved part 2 of the piping for pneumatically dispatching the iron-making raw material particles 1 including the magnetic particles 4. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
