本发明的目的是防止局部表面压力施加到夹送辊上。 夹送辊包括具有3毫米的冠部的辊体部分; 以及形成在辊体部的表面上并且设置在夹送辊的最外层上的膜的喷涂层。 在辊体部的表面上形成附着的焊接层。 喷涂层形成在附着的焊接层上。 包装辊包括具有3mm或更小的冠量的辊体部分和用作形成在辊体部分的表面上并放置在最外层上的膜的喷涂层。

An object of the present invention is to prevent the local surface pressure is applied to the pinch rolls.
A coating film is formed on both the crown surface of the roll body portion and the roll body part more than 3mm,, pinch rolls are installed on the hot rolling mill, characterized in that with a sprayed layer which is located on the outermost layer. In the body portion surface of the roll body portion, and a redundancy welding layer is formed, the sprayed layer is formed on said welding layer redundancy. A coating film is formed on both the crown surface of the roll body portion and the roll body part more than 3mm,, the wrapper roll is installed in the hot rolling mill, characterized in that with a sprayed layer which is located on the outermost layer.
