Description of the Related Art A pig iron machine is a device for placing a mold on a continuous link conveyor, casting molten pig iron into a running mold, and continuously producing die iron. There are several hundreds of molds in one cast iron machine, and inside the molds are divided into a plurality of blocks by orthogonal partition walls, and a plurality of mold pigs are simultaneously cast. The unit weight of the cast pig iron is determined by the internal volume of the block. Normally, the unit weight of the casting pig iron is
It is about 5 kg.

しながら行っている。As shown in FIG. 4, when casting hot metal in a cast iron machine, the hot metal 3 flowing out from the topede 1 is received by a receiving hot metal gutter 2 and then, via a distribution hot water gutter 4, on two mold conveyors 5. It is performed by evenly injecting it into the mold 6. The amount of hot metal injected into the mold 6 is adjusted by the driver while visually inspecting the tilting speed of the topede 1 and the speeds of the two mold conveyors 5.

That is, since the distribution of hot metal in the distribution gutter 4 is subject to a great deal of fluctuation, the driver needs to constantly monitor and adjust the work, and the adjustment delay occurs due to visual inspection, which causes non-uniform weight of the pig iron. Cheap.

持する。In the measurement of the hot metal level in the mold in the present invention, the distance from the measuring device to the hot metal level is continuously measured, and a laser or an ultrasonic wave is used as the hot metal level detecting sensor. Based on the measurement results, if the hot metal level in the mold is below a certain level (the amount of hot metal in the mold is small), adjust the speed of the mold conveyor slowly, and if it is above a certain level, adjust the speed of the mold conveyor fast. Then, the hot metal level in the mold is kept constant.

検知した場合は、トピードの傾動速度を遅くする。When the tilting speed of the topede and the casting pig iron speed do not match, more hot metal than necessary is poured into the mold, and the hot metal flows out to the downstream side of the mold conveyor. The outflow of hot metal is detected by a heat detection sensor, and the tilting speed of the topede is adjusted. That is, when the outflow of hot metal is detected by the heat detection sensor, the tilting speed of the tope is slowed.

重のばらつきの小さい型銑を製造することができる。As described above, the tilting speed of the tope is adjusted by detecting the hot metal flowing to the downstream side of the mold conveyor, and the speed of the mold conveyor is adjusted by measuring the hot metal level in the mold. In this way, the hot metal level in the mold can be kept constant and the hot metal with a small unit weight variation can be manufactured.

る。As shown in FIG. 2, the hot metal level detecting sensor 7 is installed upstream of the distribution gutter 4 and near the distribution gutter 4 in order to detect an abnormality in the hot metal level as quickly as possible. The heat detection sensor 11 for detecting the hot metal flowing out to the downstream side of the mold conveyor is installed near the distribution gutter 4 on the downstream side of the distribution gutter 4 in order to detect the outflow as quickly as possible.

It is sent to the level analysis system device 8, where only the required hot metal level is selected excluding mold partition walls, etc., and when it is out of a certain level range, a signal is sent to the motor rotation speed instruction device 9 to rotate the motor. The number indicating device 9 adjusts the speed of the mold conveyor by changing the rotation speed of the drive motor 10 of the mold conveyor based on the signal from the level analysis system device 8.

Based on the signal from the heat detection and analysis system device 12, the speeded return circuit device 13 changes the rotational speed of the speeded drive motor 14 to adjust the tilting speed of the speeded device.

運転に切り換えて鋳銑を行うことも可能である。Regarding the operation, at the start of the pig iron, the speed of inclining the speede and the speed of the mold conveyor are adjusted by manual operation, and when the pig iron becomes stable, it is switched to automatic operation. In the automatic operation, as described above, the hot metal level can be measured, the speed of the mold conveyor can be automatically adjusted, and the hot metal level in the mold can be kept constant. Further, it is possible to detect the outflow of the hot metal and automatically adjust the speed of tilting to prevent the outflow of the hot metal and to make the amount of hot metal injected into the mold constant. In the case of unexpectedness, it is possible to switch to manual operation and perform pig iron.

I'm just satisfied. In addition, the outflow of hot metal to the downstream side of the mold conveyor could be minimized. As described above, according to the method of the present invention, the hot metal can be cast into a single-weight, uniform hot metal.
