热轧窄带钢收集区域辊道传动的应用

本文介绍了唐银钢铁有限公司热轧窄带钢的生产情况。链板传动设备是成品带钢收集区域最常用的设备,带钢卷取成型后,送往打包机处包装,中间的这段运输一般采用三段链板运输的方式。由于链板传动方式固有的一些问题,使得其在实际应用中故障率较高,维护量较大,备件消耗快,增高了轧制成本。改造为辊道传动方式后,完全解决了上述问题。辊道传动在热轧窄带钢收集区域的应用可为其他生产线改造提供参考。

Multi-objective optimization of rolling schedule based on cost function for tandem cold mill

In terms of tandem cold mill productivity and product quality, a multi-objective optimization model of rolling schedule based on cost fimction was proposed to determine the stand reductions, inter-stand tensions and rolling speeds for a specified product. The proposed schedule optimization model consists of several single cost fi.mctions, which take rolling force, motor power, inter-stand tension and stand reduction into consideration. The cost function, which can evaluate how far the rolling parameters are from the ideal values, was minimized using the Nelder-Mead simplex method. The proposed rolling schedule optimization method has been applied successfully to the 5-stand tandem cold mill in Tangsteel, and the results from a case study show that the proposed method is superior to those based on empirical formulae.
