特徴とする。DISCLOSURE OF THE INVENTION The present invention provides a hard Ni that has no electrode potential difference with respect to a Ni electroplating solution and is excellent in corrosion resistance.
A base alloy is used for the conductor roll body, and on this surface,
A WC sprayed layer having a Ni-based binder is formed.

比較的簡単に製造できる。Hard Ni constituting the conductor roll body
As the base alloy, a Ni base alloy such as Hastelloy C containing Cr, Mo, Fe and W is excellent in hardness and corrosion resistance against heated hydrochloric acid forming the Ni plating solution, and can be relatively easily manufactured by centrifugal casting.

重量％の範囲内がよい。In the Ni-based alloy forming the roll substrate, if the Cr content exceeds 12% by weight, a passive film is formed and the corrosion resistance is remarkably improved. However,
If it exceeds 18% by weight, SO 4 contained in Ni plating
- and Cl - 12 to 18 for the corrosion loss is increased relative to
A range of weight% is preferable.

酸化性因子が混入した場合、腐食が加速されることか
ら、１５〜１９重量％の範囲が適当である。Further, when the Mo content exceeds 15% by weight, the corrosion resistance to hot hydrochloric acid remarkably increases, but when it exceeds 19% by weight, oxidizing factors such as iron ions contained in the Ni plating are mixed. In this case, since the corrosion is accelerated, the range of 15 to 19% by weight is suitable.

It is contained in order to obtain corrosion resistance to ions, but if it is less than 2% by weight, corrosion resistance to Fe ions cannot be obtained, and if it exceeds 10% by weight, corrosion by the Ni liquid is promoted, so that it is 2 to 10% by weight. The range is appropriate.

き、耐摩耗性に優れたロールとすることができる。Further, as the Ni-based binder used for forming the WC sprayed layer, Co which is usually used is used.
In this case, since it is corroded by NiSO 4 in the Ni plating solution, the Ni-based binder, especially its hardness is H V 100.
By using a Ni-Cr alloy-based binder of about 0, the hardness of the hard particles can be maintained at the maximum while maintaining the corrosion resistance, and the roll can be excellent in wear resistance.
