近年来,许多企业,特别是中小冶金企业掀起了一股引进二手设备的热潮。对此,各界人士褒贬不—,认为有许多值得探讨之处。归纳起来,主要有以下四个问题。 一、二手设备引进在可行性论证中参数值的定取与计算 方案的技术经济分析与可行性论证是对未来的一种预测,而方案的准确度则要取决于各基本参数的准确度。例如,在生产成本的计算中,原材料价格的确定就有很大的弹性。某钢厂在方案设计时原取铸坯价格为497.9元/吨,后考虑到实际市场价格的变动很大,在评价小连轧的经济效益时选取了与市场价较接近的单价1210元/吨,钢材成本也由原来的590.01元/吨改为1386.11元/吨,据此计算出盈亏平衡产
In recent years, many companies, especially small and medium-sized metallurgical companies, have created an upsurge in the introduction of used equipment. In this regard, people from all walks of life are not praised or criticized - they think there are many things worth exploring. To sum up, there are four main problems. I. Determination and calculation of parameter values for introduction of second-hand equipment in feasibility demonstration The technical economic analysis and feasibility demonstration of the plan are a kind of prediction for the future, and the accuracy of the plan depends on the accuracy of each basic parameter. For example, in the calculation of production costs, the determination of raw material prices has great flexibility. The original billet price of a steel plant during the design of the project was 497.9 yuan/ton. After considering the actual market price, the price of the billet was greatly changed. When evaluating the economic efficiency of the small continuous rolling, the unit price that was closer to the market price was selected. Ton, the cost of steel also changed from the original 590.01 yuan / ton to 1386.11 yuan / ton, based on which the calculation of breakeven production
