Steel cord, also known as steel cord, as a rubber skeleton material, mainly used in various types of tyres, conveyor belts, speed belts and hoses and other parts of the production, is a wire products in the high-tech, so-called "crown pearl" level products, regardless of its performance or extremely complex processing methods, there is a great deal of dependence on the quality of raw materials. Dependence. Automobile and other structural requirements for safe and reliable and lightweight development trend, determines the mainstream development direction of steel cord high strengthening, fatigue resistance, impact resistance.

In recent years, the current situation of insufficient supply of specialised wire materials for steel cord in China has formed a great contrast with the high demand and high self-sufficiency of steel cord, which provides an unparalleled market space for the wire production enterprises; in addition, the high profit level of the cord steel wire and the very high brand advantage also inspire the domestic wire enterprises to intervene in the R & D. The cord steel wire is commonly used in the production of automotive and automotive structures, such as safety and light weight.

Cord steel wire is generally used in high-carbon steel, without adding any micro-alloying elements, the main elements of the composition level is comparable, with a narrow range of composition and material purity.

Steel cord in the cold drawing and twisting process occurs in the wire breakage, which is the main reason for the presence of hard and non-deformation of the brittle inclusions in the steel. Serious surface decarburisation is very harmful to the drawing performance of cord steel wire, and it is generally required that there should not be a fully decarburised layer. The surface of the cord steel wire iron oxide, easy to remove mechanical method is required. Wire surface smooth, no surface defects visible to the naked eye after pickling.
