Abstract
PURPOSE:To permit the charge of alloy steel in optimum amount with a charging timing detectable automatically by obtaining the starting and ending timings for charging alloy steel by using the amount of steel taken out as standard. CONSTITUTION:At the start of the take-out of steel, the steel take-out speed operator 11 calculates the take-out speed of steel on the bais of weight values from the ladle weight measuring device 19 and the ladle weight sampling device 18 and then sends it to the comparator 10. On the other hand, the sectional charge operator 13 sends a steel take-out rate with charging start timing on the basis of data from the charging pattern number setter 15 and the charging pattern memory 14 to the comparatot 10. The comparator 10 sends further a chaging start timing with data from the total steel discharging amount setter 17 to the operator 13 which sets data from the hopper weight measuring device 3 and the weight sampling device 5 to the total charging amount setter 16 and also sets a sectional charging amount to the sectional charging amount setter 9. The comparator 10 calculates an alloy steel charging speed on the basis of data from the setter 9 and the operator 11 and puts it in the amplitude operator 12 to operate the feeder 2 through the amplitude setter 6 and the driving circuit 4.
