近几年来在铝工业中已明显地感到需要一种精确的板坯测厚仪。现在,轧机全是计算机程序控制的,并能完成十年前不可想象的高产量。结果,就象每吨的成本逐年降低一样而提高了利润。电子世界已经把计算机技术改进到目前能熟练控制板坯轧机的程度。计算机的价格一定要降低,但是提高轧机生产效率的真正动力将是使计算机能够发挥作用的多种 In the aluminum industry in recent years it has become clear that there is a need for an accurate slab thickness gauge. The mill is now fully computerized and capable of producing unimaginable high yields ten years ago. As a result, profit increases as the cost per ton decreases year by year. The electronic world has improved computer technology to the point where it can now master slab mills. The price of the computer must be reduced, but the real motivation to increase the mill’s productivity will be to make the computer work
