Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raw material cutting control in a raw material cutting equipment such as a blast furnace and the like. The present invention relates to a blast furnace raw material cutout control device that is cut out independently. 2. Description of the Related Art In a blast furnace raw material cutting facility, at least one ore tank and a sintering tank are installed on a weighing hopper.
The raw material is cut out from the weighing hopper by a feeder and a sieve, and when the raw material reaches a specified amount (weighing completed), the raw material is discharged from the weighing hopper to the compounding hopper. Usually, a raw material sampler is installed between a weighing hopper and a compounding hopper to analyze the components of the discharged raw material. Conventionally, when sampling an arbitrary raw material in a blast furnace raw material cut-out facility, an operator stops the automatic raw material cut-out operation, switches the cut-out control to a manual mode, and cuts out the raw material in the sampling designated tank alone. At this time, the cut-out amount of the non-sampled tank was the replenishment cut-out in the manual mode by increasing the cut-out designated amount of the other cut-out scheduled tank and the same brand tank. Or, they were replenished in the next cutout. However, in the conventional method, since cutting out to all the weighing hoppers is performed independently by the operator in the manual mode, it takes a long time to cut out the raw material, and the blast furnace piece winding (using only one mixing hopper) operation, or the blast furnace additional operation is performed. In the winding operation (continuously charging the raw materials into the blast furnace), there is a problem that a discharge delay from the compounding hopper occurs. SUMMARY OF THE INVENTION The present invention solves such a conventional problem and eliminates the need to stop the automatic operation when sampling is specified, and to set the cut-out amount set value for a tank not specified for sampling. It is an object of the present invention to provide a control device capable of automatically sorting to other same brand tanks and cutting out only the raw material of a designated sampling tank alone. [0005] In order to solve the above problems, a raw material cutting control device of the present invention comprises a sintering tank containing a sintering raw material, an ore tank containing an ore raw material, and A plurality of cutting systems each including a cutting device provided in each of the knot tub and the ore tank, and a weighing hopper that receives the raw materials selectively or simultaneously cut by the cutting device are provided, and the raw material discharged from each of the weighing hoppers is provided. In a raw material cutting facility having a conveyor to be transferred, a compounding hopper provided at the end of the conveyor and receiving the raw material, and a raw material sampling device provided between the end of the conveyor and the compounding hopper, a certain cutting system is used. During the simultaneous cutting of the sintering raw material and the ore raw material to the conveyor, a sample collection command is issued to the raw material sampling device. When output, cut out only the raw material tank specified for sampling and weigh it, discharge the weighed raw material to the conveyor, perform sampling by the raw material sampling device, and cut out the raw material tank for which no sampling is specified. Control means for performing the distribution by adding and dividing the set amount to the cut amount set value of the tank of the same brand as the raw material for which the sampling was not specified, of the cut system other than the cut system specified for sampling, and performing cutting. is there. According to the present invention, before the raw material is cut out from the sintering tank A or the ore tank B to the weighing hopper, the raw material sampling designated tank (A
Or B) is extracted, the cut-out amount set value of the unspecified tank (B or A) is automatically set to zero, and the material cut-out control mode is automatically changed from the AB mixed cut-out mode to the single cut-out mode (B or A) Then, the cutout can be automatically stopped and the set amount of the cutout can be automatically distributed to other cutout scheduled tanks and the same brand of tank as the tank whose cutout has been canceled. According to the present invention, it is not necessary to switch the cut-out control mode to the weighing hopper to the manual mode at the time of raw material sampling, and to separate the cut-out set value to another tank with the intervention of the operator. That is, it is not necessary to stop the automatic cutting operation control, so that the cutting control can be performed without wasting time. Next, an embodiment of the present invention will be described with reference to the drawings. 1 and 2 show one embodiment of the present invention.

Hereinafter, the blast furnace raw material cutout control based on the control method according to the present invention will be described with reference to the raw material cutout control flowchart of FIG. 1) The conditions for cutting out from the sintering tank 1 and the ore tank 2 to the weighing hopper 6 are satisfied, and the presence or absence of material sampling designation is extracted before starting cutting, and if sampling is designated, the sampling designation tank is stored (step). 100, 110, 120). 2)
When the sampling designated tank is the sintering tank 1, the cutout amount set value WB of the ore tank 2 is set to zero, and the cutout control mode is automatically set in the sintering tank 1 (steps 130 and 14).
0). Next, the number of tanks X of the same brand as the ore tank B which is currently scheduled to be cut out of the other ore tanks B and whose sampling is not specified is calculated (step 150).
The total value obtained by adding the cut-out replenishment amount (WB / X) to the cut-out amount set value of the same brand tank is set as the cut-out amount set value of the same brand tank (step 160). 3) When the designated sampling tank is the ore tank 2, the cutout amount set value WA of the sintering tank 1 is set to zero, and the cutout control mode is automatically set in the ore tank 2 (steps 190 and 200). Next, the number of tanks Y of the same brand as the other sintering tanks 1 which are scheduled to be cut out of the other sintering tanks 1 and which are not designated for sampling are calculated (step 210). The cut-out replenishment amount (WA /
The total value obtained by adding Y) is set as the cutout amount set value of the same brand tank (step 220). 4) From then on, the conventional automatic control of raw material cutout, the control of raw material weighing, and the automatic control of raw material discharge are executed (steps 170 and 180).
