DEVICE FOR MEASURING WEIGHT OF RECEIVED ORE SCRAP OF BLAST FURNACE TORPEDO CAR

摘要

PURPOSE: To measure an accurate weight by obtaining a compensation coefficient while considering the transition of the difference between the torpedo received ore scrap weight measurement value in past compensation and teacher's data. ;CONSTITUTION: A blast furnace torpedo car weighing machine 10 obtains the entire weight of a torpedo car and calculates the received ore scrap weight before compensation from the difference between the current total weight and the total weight before starting ore shipment. Also, a converter weighing machine 20 increases or decreases desilicified material which is balanced by scrap exhaust treatment and the amount of scrap exhaust to create teacher's data. Then, a received ore scrap weight operation device 31 multiplies the received ore scrap weight before compensation which is calculated by the weighing machine 10 by a compensation coefficient to obtain the received ore scrap weight after compensation and a data diagnosis device 32 diagnosis the validity of teacher's data from the weighing machine 20. Then, a compensation coefficient calculation device 33 obtains a new compensation coefficient considering the transition between the received ore scrap weight measurement value in past compensation and the teacher's data and then stores 34 it so that the device 31 can use it next time.;COPYRIGHT: (C)1995,JPO
