本発明ロールにおいて、ロール片は直接被成形材に接触
して加熱される作用ロール片のみならず、ボスロール等
各ロール片、さらに一体でなるロールをも意味する。In the roll of the present invention, the roll piece refers not only to the working roll piece that is heated by directly contacting the material to be formed, but also to each roll piece such as a boss roll, and also to an integral roll.
良熱伝導性金属パイプとして、銅パイプは、熱伝導性、
被加工性の面で優れ適当である。As a metal pipe with good thermal conductivity, copper pipe has good thermal conductivity,
It is suitable for excellent workability.
ロール片に形成する溝は、その形成加工上周方向とし、
その内面に亜鉛、銅等のメツキを施すことにより、露結
にともなう腐食を防止して接触熱伝導の低下を防止し、
また金属パイプとの接触を良好にするので有効である。The grooves formed on the roll piece are formed in the upper circumferential direction,
By plating the inner surface with zinc, copper, etc., it prevents corrosion caused by dew condensation and reduces contact heat conduction.
It is also effective because it makes good contact with metal pipes.
さらに金属パイプ埋設後メツキを施すことも有効である
。Furthermore, it is also effective to plate the metal pipe after burying it.
また、この溝の寸法、形状およびパイプの埋設方法を調
整して、ロール片と金属パイプとの接触面積を増加させ
