Research on Molten Iron Vertical Flow Rate and Level Based on Dynamic Infrared Radiation and Time Intervals

摘要

In the foundry, it's difficult to measure the level of molten iron in pouring package and the flow of molten iron each pouring during casting control process, which will result in the control problem of over-pouring and under-pouring. So, a new measurement method about molten iron level and dynamic detection of vertical flow rate has been developed in this paper. The method is based on infrared radiation and time intervals under the state of vertical flow rate of molten iron. By analysing the flow rate of molten iron in the casting ladle taphole theoretically, building field experimental device and analysing experimental results, it shows that the proposed iron level measurement and dynamic detection of vertical flow rate based on infrared radiation and time intervals are feasible. And then it lays a foundation for controlling the flow of molten iron.
