天铁集团棒线厂45^#硬线盘条研发

Research and Development of 45 Graded High Carbon Wire Rod at Tiantie Group Wire and Rod Mill

天铁棒线厂为增加线材产品的新品种,研发出45#硬线盘条。对研发过程中存在的脱碳、晶粒粗大、混晶现象等缺陷的原因进行分析,改进了原生产工艺方案,采用新方案轧制,消除了原工艺生产过程中的几种缺陷,成功生产出了符合国标要求的45#硬线盘条,满足了市场对硬线钢的需求,提高了经济效益。

In order to add a new grade to wire product, Tiantie Wire and Rod Mill developed 45 graded high carbon wire rod. The defects of decarburization, coarse grain and grain mixing in product development were analyzed. The mill improved original production process, adopted new rolling plan, eliminated the defects in the original process and successfully produced 45 graded high carbon wire rod which was in accordance with national standard. The requirement of market on high carbon steel was met and economic benefit increased.
