持する。The measurement of the hot metal level in the mold in the present invention is to continuously measure the distance from the measuring device to the hot metal level, and a laser or an ultrasonic wave is used as a sensor for detecting the hot metal level. 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 faster. To keep the hot metal level in the mold constant.

検知した場合は、トピードの傾動速度を遅くする。[0008] If the tilting speed of the torpedo does not coincide with the speed of the cast iron, excess hot metal is injected into the mold, and the hot metal flows downstream of the mold conveyor. The leaked hot metal is detected by a heat detection sensor, and the tilting speed of the topeed is adjusted. That is, when the hot metal is detected by the heat detection sensor, the tilting speed of the tope is reduced.

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 torpedo 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, it is possible to maintain a constant level of the hot metal in the mold and to produce a pig iron having a small single weight variation.

It is sent to the level analysis system device 8, where only the required hot metal level is selected excluding the partition walls of the mold, etc., and if it is out of a certain level range, a signal is sent to the motor rotation speed indicating device 9, and the motor rotation speed is transmitted. 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.

In the automatic operation, as described above, the hot metal level is measured, the speed of the mold conveyor is automatically adjusted, and the hot metal level in the mold can be kept constant. In addition, it is possible to detect the outflow of hot metal, automatically adjust the topped tilting speed, prevent the outflow of hot metal, and keep the amount of hot metal injected into the mold constant. In addition, in the case of unexpectedness, it is also possible to switch to manual operation and perform casting iron.
