本文从理论上分析无心感应熔化炉电、热与总效率跟坩埚壁厚的关系入手,深入探讨了最佳厚度的电算法(数值计算法),并编制了简化的电子计算机程序,适用于各种容量以及不同的金属炉料。文中列举了熔化钢、铸铁、铜以及铝等五种炉子的坩埚壁最佳厚度电算法的实例,计算结果与生产实际吻合。这说明文中所提出的电算法以及程序,可直接用于耐火材料打结的无心感应熔化炉炉衬最佳厚度的设计。
Based on the analysis of the relationship between electricity, heat and total efficiency of heartless induction melting furnace and the thickness of the crucible, this paper discusses in depth the electricity algorithm with the best thickness (numerical method), and compiles a simplified electronic computer program for each Capacity and different metal charge. The paper gives an example of the algorithm of optimal thickness of crucible wall for five kinds of furnaces, including molten steel, cast iron, copper and aluminum. The calculation results coincide with the actual production. This description presented in the algorithm and the program can be directly used for refractory knotted heartless induction melting furnace lining optimal thickness design.
