贵冶卡尔多炉是国内首台主要用于处理废杂铜的冶金炉,目前对国外卡尔多炉了解甚少,无指标可比较.通过几年的生产实践,卡尔多炉仍有部分不如意的技经指标,如生产成本较高、金属回收率低等.如何持续优化卡尔多炉技术经济指标,我们以类似杂铜冶炼炉好的指标为标杆,制定更高技术指标作为工作目标. 相似文献

There are lots of physical changes and chemical reactions in the processes of iron and steel making, these processes are quite complex in the aspect of heat transfer.The processes of iron and steel making can be approximately divided into three kinds.The first kinds are the processes of fusion metallurgy which involve enormous chemical reactions,such as blast furnace,converter,electric furnace and coke oven.The second kinds are the processes of heating and cooling which are mainly the physical changes,such as walking-beam reheating furnace,annular heating furnace and car-type furnace.The third kinds are the processes of heat treatment which mainly adjust metallurgical structure of metal,such as roller hearth heat treatment furnace, strip continuous heat treatment vertical/horizontal furnace and HPH bell-type annealing furnace.Every process can only be finished in particular thermal equipment.And all the physical and chemical processes mentioned above must obey first principles of engineering thermodynamics,heat & mass transfer,hydromechanics, combustion,metallurgy physical chemistry etc,and which can be summarized as principle of heat transfer,mass transfer,momentum transfer and chemistry reaction.In this paper,based on first principle of heat and mass transfer in iron and steel making processes,a series of mathematical models of thermal equipments and processes are presented.Such as the model of hot-blast stoves,coke oven,CDQ-boiler system,sintering, reheating furnace,soaking furnace,annular heating furnace,roller hearth heat treatment furnace,strip continuous heat treatment vertical/horizontal furnace,HPH bell-type annealing furnace,control cooling of medium plate,burner,heat exchanger and regenerative burner etc.The on-line application of the model is based on experimental certification of the mathematical model.And finally the computer optimization system of metallurgical thermal process is obtained. 相似文献

A mathematical model to control thermal stability of blast furnace using proactive thermal indicator
The determination of thermal condition of the blast furnace is necessary for various reasons, such as to facilitate the operation, maintain a stable furnace condition, predict heat or heat tendency of the furnace and predict hot metal temperature (HMT). It can become a tool for controlling the product quality of the blast furnace. This paper presents a mathematical model for estimating the thermal tendency of the blast furnace. The thermal condition of the blast furnace is represented as thermal energy index, wherein a high thermal energy index denotes heating up of furnace, while a low thermal energy index indicates chilling down of furnace. Using this model, one could hypothetically estimate the thermal condition of the blast furnace in real time. Thereby, corrective controllable actions can be taken on real time to attain the desired HMT before the arrival of actual hot metal analysis. 相似文献
