Boronized laying pipe |
摘要 |
A laying pipe for use in the laying head of a rolling mill is configured for rotation about an axis, with an entry end aligned on that axis to receive a hot rolled product, and with a curved section leading to a delivery end spaced radially from that axis. The curved section defines a guide path configured to form the hot rolled product into a helical formation of rings. The laying pipe comprises a tubular ferrous wall having an interior surface comprising a wear resistant boronized layer against which the hot rolled product is confined for movement along the guide path. |
