PURPOSE:To easily and inexpensively produce the extremely fine Ti wire having good quality by coating the outer periphery of Ti wire rods with a low-carbon steel strip, heating the wire rods at a specific temp., subjecting the wire rods to hot rolling at a specific temp. and then cooling the wire rods at a specific cooling rate. CONSTITUTION:The assembly of the coated wire rod formed by sticking a power mixture composed of mica and glass onto the surface of the Ti wire rods, then coating the outer periphery thereof with the low-carbon steel strip is used as an inside layer and the outside layer part is formed of the low-carbon steel. This billet is heated to <=1000 deg.C and is in succession subjected to the hot rolling at <=950 deg.C; thereafter, the wire rod is cooled at >=1 deg.C/sec cooling rate to obtain the wire rod in which plural pieces of the extremely fine Ti wire are included in obtd. The low-carbon steel part of this wire rod is thereafter dissolved away by using an acid. The extremely fine Ti wire having the good quality is easily obtd. in this way. |
