我公司生产的钢帘线用热轧盘条，产品标准为YB/T170.4-2002及企业内控，主要牌号有C72D2、C82D2，主要用于拉拔普通强度和高强度钢帘线。此钢种由于其使用性能的特殊性，拉拔变形量极大，要求钢中S、P等含量低、对夹杂物的数量、种类和形态有很高的要求，轧制公差尺寸精确。我公司已大批量生产基本满足用户要求的C72D2、C82D2钢帘线用热轧盘条。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.
