在大量的现场试验与理论研究的基础上,充分考虑到冷连轧机高速轧制的生产工艺特点,以各个机架轧制温度相对均匀为目标,把保证终卷温度在设定范围内且乳化液满足相关工艺要求作为约束条件,建立了一套冷连轧机高速轧制温度自动控制模型,并将其应用到宝钢1220冷连轧机的生产实践,通过对乳化液的浓度、温度、流量密度等关键参数的优化设定,实现了轧制温度与终卷温度的最优控制,有效的保证了带钢表面质量与板形精度,为机组创造了较大的经济效益,具有进一步的推广应用价值。
On the basis of a large number of field experiments and theoretical studies, taking fully into account the characteristics of high-speed rolling tandem cold mill production process, with each rack rolling temperature is relatively uniform as the goal, to ensure that the final volume of the final volume and within the framework of the emulsion Liquid to meet the requirements of the relevant process as a constraint condition, a set of automatic control model for high speed rolling temperature of tandem cold mill was established and applied to the practice of Baosteel 1220 tandem cold rolling mill. The emulsion concentration, temperature, flux density The optimal setting of the key parameters realizes the optimal control of the rolling temperature and the final coil temperature, effectively ensures the strip surface quality and the precision of the strip shape, creates a great economic benefit for the generating set, and has further popularization and application value .
