Document Type and Number:
Japanese Patent JPH0649721
Kind Code:
A
Abstract:
PURPOSE: To obtain a spinning frame ring made of steel, enabling a traveler to be operated at high speed and enabling both a ring and a traveler to have a long lifetime by applying heat treatment for low carbon steel to a ring made of high carbon steel.
CONSTITUTION: This method is to apply heat treatment (e.g. carburizing treatment, nitriding one, carbonitriding one, nitrocarburizing one, cyanidation one and other surface hardening one) for low carbon steel to a ring made of high carbon steel.
