monitoring by blast furnace hearth slag iron discharge volume total amount and the theoretical volume total amount that generates of blast furnace hearth slag iron by the multi-level computer management system of blast furnace monitoring cupola well slag iron amount.The theoretical volume total amount that generates of described this blast furnace hearth slag iron discharge volume total amount and blast furnace hearth slag iron is compared, for example the theoretical volume total amount that generates of cupola well slag iron discharge volume total amount and cupola well slag iron is added up comparison, such comparison more intuitively, more definite.Further adopt blast furnace hearth slag iron discharge volume total amount and the theoretical difference that generates the volume total amount of blast furnace hearth slag iron to measure the method for monitoring by the multi-level computer management system.And then the method that adopts blast furnace hearth slag iron discharge volume total amount and the theoretical positive negative value accumulative total of residual quantity that generates the volume total amount of blast furnace hearth slag iron to monitor again.The theoretical positive negative value accumulative total of residual quantity that generates the volume total amount of described blast furnace hearth slag iron discharge volume total amount and blast furnace hearth slag iron, for example the theoretical positive negative value of difference that generates the volume total amount of cupola well slag iron discharge volume total amount and cupola well slag iron is carried out statistical measurement respectively, for example in certain period the theoretical difference that generates the volume total amount of cupola well slag iron discharge volume total amount and cupola well slag iron be on the occasion of, mean that this blast furnace hearth slag iron volume total amount discharge is greater than generation, this blast furnace hearth slag iron liquid level becomes downtrending, how long have so during this period of time? for example the theoretical difference that generates the volume total amount of cupola well slag iron discharge volume total amount and cupola well slag iron is a negative value in certain period, mean that this blast furnace hearth slag iron volume total amount discharge is less than generation, this blast furnace hearth slag iron liquid level becomes ascendant trend, how long have again so during this period of time? with this difference on the occasion of, negative value is added up comparison respectively, such comparison is monitored for super-huge blast furnace hearth slag iron amount, monitoring waits management more directly perceived, more careful, more accurate, Practical significance is more arranged.Fig. 3 illustrates this routine blast furnace slag iron discharge volume and theoretical volume accumulative total generative process (logical relation) figure that generates of blast furnace slag iron.Fig. 4 and Fig. 5 show the practical situation of slag iron discharging one day (also being cupola well slag iron quantity discharged) of this example blast furnace, about this example blast furnace one day stove cupola well slag iron quantity discharged practical situation, see also described in embodiment one .1. no longer stating more.
