针对影响加热炉总括热吸收率的因素相互耦合,难以实时动态调整的不足,通过建立炉温对板坯温度的感度方程,以板坯加热工艺为基础,针对加热炉板坯温度跟踪计算时的总括热吸收率模型的不足,提出了基于板坯温度感度的总括热吸收率的计算方法,使得总括热吸收率可以根据炉温以及板坯的温度变化情况进行实时调整,极大地提升了板坯总括热吸收率对于生产条件波动较快时的适应性。实践表明,计算结果在特殊炉况时也取得了理想的效果。
According to the factors affecting the overall heat absorption rate of the heating furnace, the factors which affect the total heat absorption rate of the heating furnace are mutually coupled, which makes it difficult to adjust the temperature in real time. By establishing the sensitivity equation of the temperature of the furnace on the temperature of the slab and the slab heating technology, Summarizing the shortage of the heat absorption rate model, the calculation method of the total heat absorption rate based on the temperature sensitivity of the slab is proposed, so that the total heat absorption rate can be adjusted in real time according to the temperature of the slab and the temperature variation of the slab, Summarize the adaptability of heat absorption to fluctuations in production conditions. Practice shows that the calculation results in the special furnace conditions also achieved the desired results.
