1. Steel Wire Rod for WeldingGB/T3429-2002 and internal control standard is adopted for this product. The steel wire rod for welding could be used to produce welding rod, gas shield welding wire and submerged arc welding and so on. The main grades are H08A, ER50-6 (E), H08Mn2SiA, H08MnA and so on. With million tons of annual production, higher market occupation rate and more than 120 customers, this product is in great demand in more than 20 provinces and cities in domestic market and even sold abroad as well. In recent years, in order to meet the customers’ requirements, some special soldering wire is developed one after another, such as ER50-C (with Mo), ER50-G (with Ti), EH14 and EM12K. In 2001, this product was awarded with the “Golden Cup Prize” of metallurgical product quality by China Iron and Steel Association and the steel wire rod for the gas shielded welding wire won the title of “Famous Brand of Shandong Province” and confirmed again in 2003. The steel for welding rod H08A of QIS has a long history and is popular to many customers. After the realization of continuous casting in 1997, the wire rod for welding rod of H08A is accepted firstly by the market, and is evaluated as the “New Product of National Level” by China Economy and Trading Association and won the prize of Metallurgical Science and Technology progress of Shandong Province and Excellent New Product of Qingdao. With the uniform and stable components, steel quality, metallographic structure and mechanical performance, the steel wire rod for welding of ∮5.5mm ER50-6E produced by our company could be drawn directly to the product of ∮1.0mm without interannealing under the condition of higher drawing velocity. This product comes up to the domestic advanced level with the features of less welding splashing, smooth and good welding seam and high strength and gained the

10. 碳素结构钢:10. Carbon Structure Steel

主要分为盘条和圆钢。现执行 GB/T700 –2006 及相应产品标准。我公司生产的

Q195、LS08、1008 等盘条主要用于拉丝,Q235 盘条多用于建筑及冷轧带肋钢筋用

母料。高速线材轧机生产的产品具有盘重大,表面氧化铁皮少,尺寸公差精确等特点。

低碳钢无扭控冷热轧盘条 1999 年首次被评为山东省名牌产品,2003 年度再次确认;

热轧盘条获 2002 年度青岛市名牌产品称号;2004 年度获全国用户满意产品、冶金产

品实物质量“金杯奖”。

The main products of carbon structure steel are wire rod and round bar, adopting GB/T700 –2006 and corresponding products standards. The wire rod of Q195, LS08 and 1008 produced by QIS are mainly utilized for wiredrawing, and the wire rod of Q235, for construction and the base metal of cold rolled reinforced bar with rib. Products produced by the high speed rolling mill have those advantages as heavy coil weight, less surface scale and precise dimension tolerance. In 1999, the low carbon steel non-twisting controlled cooling and hot rolled wire was evaluated as Shandong Provincial Famous Brand Product at its first time,

22
