电炉合适规模的选择——从经济效益及投资方面来看,电炉越大越好吗?

CHOOSING THE RIGHT SIZE SMELTING FURNACEAre bigger furnaces better, from an economic/investment perspective?

随着大型电炉的发展,铁合金生产效率和经济效益不断提高,从而使得单位生产成本不断下降。此原理也一定适合世界各国铁合金生产者。 然而,世界各国铁合金生产者一直趋于将不同规格的电炉标准化。在不同国家之间不同规格电炉的选择是基于经济上的原因吗?那么,较大电炉比较小电炉要好吗?一个较大型电炉要好过两个小型电炉吗? 本文从投资角度出发,建立了一个简单的经济模型,来预测较大电炉是否总是获益。

With the development of larger smelting furnaces, there have been increased efficiencies and economies of scale, resulting in lower unit production costs. This basic principle must apply to all ferroalloy producers in all countries.However, ferroalloy producers in different countries have tended to standardise on different size furnaces. Are there economic reasons for the different size selection between countries? Is a larger furnace better than a smaller one? Is one larger furnace better than two smaller ones?In this paper a simple economic model is developed to predict, from an investment perspective, if there is always benefit to be had from larger furnaces.
