Abstract
A ceramic guide for a rolling line, used for wire rod transfer in a rolling line, which has a cylindrical contour and a throughhole for wire rod transfer. The throughhole includes a tapered hole and a straight hole of constant diameter, the tapered hole being provided at the wire rod inlet side of the guide. This ceramic guide, when used in a rolling line, is less liable to cause seizure with a wire rod and has higher durability.
