Method for computing corrosion of blast-furnace crucible through PLC procedure

The invention relates to a method for computing corrosion of a blast-furnace crucible through a PLC procedure, and belongs to the technical field of blast furnace automatic control. According to the technical scheme, computing of each parameter is achieved by additionally arranging a carbon brick corrosion model computing module in the PLC control procedure; and each corrosion parameter and the tendency and dynamic models thereof can be looked over rapidly in real time in a picture, the visual degree and clarity of the parameters are higher, technologists can look for the carbon brick corrosion conditions more conveniently, the production accidents are effectively reduced, the labor intensity of staff is relieved, and a good foundation is laid for stable production of a blast furnace and prolonging of the furnace age of the blast furnace. 本发明涉及种利用PLC程序计算碳砖侵蚀的方法，属于高炉自动控制技术领域。技术方案是：通过在PLC控制程序中新增碳砖侵蚀模型计算模块实现各参数的计算；在画面中可快速、实时的查看各侵蚀参数，以及这些参数的趋势、动态模型，更直观、明了，方便工艺技术人员查看碳砖侵蚀情况，有效减少生产事故，减轻职工的劳动强度，为高炉稳定生产，延长高炉炉龄，打下良好的基础
