Problems solved by technology

[0002] The steel cord is the skeleton support material in the tire. During the processing of the steel cord, multiple frequent wire drawing operations are required. The raw material coil is drawn into a slender steel wire, which is twisted into a steel cord after electroplating. , and the technical difficulty lies in the fact that fractures are common and difficult to control during the wire drawing process. For the processing of steel cords of different specifications, it is necessary to accurately set the pulling force of the wire drawing machine, and to control the temperature and ph value of the wire drawing liquid. There are common measures to reduce fractures in the technology, but these control methods have high requirements for the equipment of the wire drawing machine, the accuracy of the domestic wire drawing machine is still lacking, and the price of the European wire drawing machine is expensive. For small and medium-sized manufacturers, the cost is relatively high. high

Abstract

The invention provides a steel cord capable of effectively reducing central burst and a wire drawing processing method thereof. The content of a chromium element in a raw material coiled material is controlled, the chromium element is favorable for forming a compact sheet structure on the surface of a steel wire, the fiber strength is improved, austenite residues in a heat treatment process causedby excessive pearlite are prevented, and removal difficulty of surface acidifiers in a mechanical rust removal process is reduced.

Description

technical field [0001] The invention relates to the field of steel cord processing, in particular to a steel cord capable of effectively reducing central bursting and a wire drawing processing method thereof. Background technique [0002] The steel cord is the skeleton support material in the tire. During the processing of the steel cord, multiple frequent wire drawing operations are required. The raw material coil is drawn into a slender steel wire, which is twisted into a steel cord after electroplating. , and the technical difficulty lies in the fact that fractures are common and difficult to control during the wire drawing process. For the processing of steel cords of different specifications, it is necessary to accurately set the pulling force of the wire drawing machine, and to control the temperature and ph value of the wire drawing liquid. There are common measures to reduce fractures in the technology, but these control methods have high requirements for the equipme...
