Under the standard of YB/T170.4-2002 and enterprise inside control standard, the main grade of the hot rolled wire coil for steel cord are C72D2 and C82D2. Because of the very large deformation in the process of stretching the tire bead wire of common and high strength, it is required to have less contents of S and P, very high requirement to the quantities and varieties of the impurity and accurate rolling tolerance. QIS has been in volume production to meet the customers’ demand.
