C型料场因具有占地省、贮量大、环保节能等优点在钢铁厂得到广泛应用,为了避免因粗略估算造成料堆体积计算的偏差,通过对C型料场料堆形成机理的研究,应用高等数学中二重积分的原理,对料堆进行合理划分,从而得到料堆体积计算的精确公式;通过与三维放样料堆体积的对比,检验了精确公式的可靠性和误差度,从而有效地解决了料堆体积计算的问题;通过卸料点步长与料堆体积的回归分析,提出了合理选择步长的重要性。 Due to the advantages of land occupation, large storage capacity, environmental protection and energy saving, C type material yard has been widely used in steel mills. In order to avoid the discrepancy of material pile volume calculation due to rough estimation, through the research on the formation mechanism of material pile in C type material yard , The principle of double integral in advanced mathematics is applied to reasonably divide the material heap so as to get the exact formula of the material heap volume calculation. By comparing with the volume of the three-dimensional lofting material pile, the reliability and error degree of the exact formula are verified Which effectively solves the problem of material pile volume calculation. Based on the regression analysis of the discharge point step size and the material pile volume, the importance of reasonable selection of the step size is proposed.
