攀钢2号大方坯连铸机优化设计及改造
|
摘要
攀钢对原有2号方连铸机进行了改造,新增410 mm×320 mm断面,产品以生产百米高速重轨钢为主。通过对结晶器、扇形段、二冷区、二级系统等进行优化设计和设备改造,所生产的铸坯质量基本满足了百米重轨的轧制需求。目前,正在进一步优化生产工艺,以提高最终高速重轨产品质量。
Pan steel revamped No.2 bloom caster, and added 410 mm×320 mm cross section. No.2 caster's mainly produce was"100 m heavy rail"steel. By optimizing design and revamping mould,segments, second cooling system, and level 2 system, the bloom quality met the heavy rail rolling demands. In the future, the production process will be optimized further to increase the rail quality.
