According to the main characteristics of production line of iron and steel enterprise, how to make aggregate production planning of iron and steel enterprise are analyzed. An aggregate production plan model of product line of iron and steel enterprise is proposed, which is calculated by using standard library function of the Matlab7.0 genetic algorithm(More)
Coke oven is a complex plant with the characteristics of large time-delay, strong non-linear, multivariable coupling and changeable parameters. The longitudinal temperature was affected by many reasons, the control principle of combining the intermittent heating control with the heating gas flow adjustment was adopted. Intelligent control methods, namely(More)
Electric furnace roof is an important device for electric steel making, whose heat preservation performance and lifespan have a direct impact on the economic benefits of iron and steel enterprise. Considered contact behavior between prefabricate block, this paper establishes the complete CAD/CAE model of the electric furnace roof with finite element(More)
Ladle is an important container in metallurgy industry, and its lifetime is very important for the natural production of enterprise. The stand or fall of refractory lining of ladle decides its lifetime, yet thermal stress is the direct reason of causing refractory lining breakage. In this paper the structure of ladle mainly by changing the structure of(More)
