Title:
STEEL CORD AND MANUFACTURING METHOD THEREFOR, AND TIRE PROVIDED WITH STEEL CORD
Document Type and Number:
WIPO Patent Application WO/2020/113606
Kind Code:
A1
Abstract:
Disclosed is a steel cord manufactured by twisting a single wire. The hardness of the cross section of the single wire is regularly distributed in an inverted "V" shape. The hardness of the core of the cross section of the single wire is high, while the hardness of the edge thereof is low. The difference between the hardness of the core and of the edge of the cross section of the single wire is 10-100 Hv. The present invention further relates to a method for manufacturing the steel cord, and a tire provided with the steel cord. The single wire does not delaminate during a twisting test process, and there are less broken wires when the single wire is twisted into the steel cord during a production process; therefore, the manufacturing method is suitable for the batch production of single wires of steel cords with ultra-high strength and above, and for the batch production of steel cords.
