一、控制目标与任务冲天炉是铸造车间获得铁水的主要熔炼设备。一台冲天炉判断其熔量效果的指标,必须是全面达到高温、优质、低消耗三项技术经济指标。微计算机用于冲天炉控制的目标和任务,就是在于实现这些指标;即铁水化学成分准确稳定,铁水温度达到要求,同时又要使冲天炉在最佳工作状态运行,即焦炭燃烧效率高而消耗低,元素烧损少,生产率稳定。二、控制特点与参数冲天炉熔炼效果受到许多因素的影响,其中包括冶金因素,例如炉料原材料来源、配
First, the control objectives and tasks Cupola is the foundry to obtain the main melting equipment of molten iron. A cupola to determine the melting capacity of the indicators, it must be fully reached high temperature, high quality, low consumption of three technical and economic indicators. Microcomputer control and cupola for the purpose and mission, it is to achieve these indicators; that is, accurate and stable chemical composition of molten iron, hot metal temperature to meet the requirements, but also to make Cupola running in the best working condition, that coke burning high efficiency and consumption Low, less burning elements, productivity and stability. Second, the control characteristics and parameters Cupola melting effect by many factors, including metallurgical factors, such as the source of raw materials, with charge
