<div class="over_x"><p>首钢京唐公司热轧作业部积极优化轧制工艺，在产品开发试制方面实现新突破。2月份上半月，成功轧制高档汽车外板热轧板卷5500吨，并试轧成功汽车结构件钢。</p>
<p>此次轧制的DC06钢为无间隙原子钢，具备较高的延伸率和优异的成型性，适用于形状复杂、表面质量要求特别严格的汽车冲压件，生产难度极大。为了能尽快轧制出合格的汽车外板热轧板卷，热轧部反复核对轧制要点，从轧制工艺负责人到现场操作职工集体攻关、群策群力，攻克难关。2月10日至14日，共轧制厚度1.2&mdash;5.5毫米DC系列汽车外板5500吨，产品表面质量和性能均达标，期间又试轧了规格1.85毫米&times;1275毫米的两卷汽车结构件钢，强硬度、轧制楔形和平直度等指标均达到要求。</p>
<p>DC06钢等高附加值钢种的成功下线，标志着热轧轧材生产管理技术操作水平跃上了一个新台阶。</p>
