溶滓冷却機に関するものである。[Detailed Description of the Invention] The present invention provides a metallic heat exchange medium (metallic heat exchange medium)
In a slag cooling machine, the temperature of slag is lowered by endlessly repeating the process of immersing a cooling plate (hereinafter referred to as a cooling plate) to absorb heat, and then immersing this cooling plate in running water to cool the slag. This invention relates to a slag cooling machine that can automatically control operation in response to changes in slag temperature and flow rate while maintaining performance.

に、実際の操業では溶滓の温度・流量と共に変化してい
るのが実情であった。Conventionally, in slag cooling machines, the amount of heat absorbed while the cooling plate is immersed in the slag and the amount of heat released while passing through the water tank are the same, that is, the amount of heat absorbed and released by the cooling plate is the same. Although it is important to operate with a balanced amount of heat, in actual operation, the temperature and flow rate of the slag change.

いた。In addition, the amount of heat absorbed by the cooling plate increases or decreases depending on the temperature on the slag side and the magnitude of the flow rate, while the amount of heat dissipated from the cooling plate increases or decreases depending on the temperature of the water supplied to the water tank and the magnitude of the flow rate of the supplied water. was.

ことを目的とするもので゛ある。The present invention was developed in view of the above points, and although it is impossible to quantitatively and continuously detect moment-to-moment fluctuations in the temperature and flow rate of the slag during actual operation, the temperature on the surface of the cooling plate Focusing on the fact that continuous quantitative detection is possible with this method, we can detect the surface temperature of the cooling plate after it has finished cooling in water, adjust the amount of cooling water, and check the temperature of the cooling plate before it enters the slag again. It is possible to keep the temperature constant, or to detect the surface temperature of the cooling plate before it is lifted from the slag and enters the water, and quantitative continuous detection is possible in the form of the surface temperature of the cooling plate, which is the cooling medium. Focusing on certain things, we detected the surface temperature of the cooling plate after it had finished cooling in water and adjusted the amount of cooling water to keep the temperature of the cooling plate constant before entering the slag again. Before entering the water raised from the slag, the surface temperature of the cooling plate is detected, and the immersion depth and/or moving speed of the cooling plate in the slag is adjusted based on this. The object of the present invention is to provide a slag cooler that can automatically adjust the amount of heat absorbed or released.

The amount of heat absorption 9 can be adjusted by changing the speed of movement of the cooling plate 9 by changing the rotation speed of the variable speed electric motor 20.

Even if the temperature T1 of the cooling plate 9 changes due to changes in the flow rate or temperature of the slag 1, by adjusting the amount of chilled water Q, the temperature T2 of the cooling plate 9 when it comes out of the water tank 13 can be adjusted. can be held constant.

。Normally, if the flow rate and temperature of the slag vary within a range, for example, if the flow rate is 3 to 4 t/min and the temperature is 1450 to 1550°C, a sufficiently satisfactory adjustment result can be obtained by adjusting the amount of cooling water as described above. In actual operation, the flow rate of the slag may momentarily reach a large amount, for example, a peak amount of 7 t/min to 9 t/min, and in this case, first the cooling plate 9 When the temperature T1 of the temperature rises abnormally, this is detected, and when it reaches the set temperature or higher, the electric jack 19 is activated by the signal from the T1 temperature recording controller to raise the tail tumbler 6B and cool it down. By reducing the immersion depth of the plate 9 in the slag 1, it is possible to prevent the temperature T1 of the cooling plate 9 from rising above a set value.

If the flow rate of the slag 1 is less than 2 t/min or its temperature is less than 1400°C, reduce the rotation speed of the variable speed motor to slow the moving speed of the cooling plate 9, and reduce the amount of heat absorbed. You can also reduce it.

By adjusting the immersion depth of the cooling plate in the slag and adjusting the amount of cooling water to the water tank, it is possible to balance the amount of heat absorbed and the amount of heat released by the cooling plate by adjusting all or part of these. This has the excellent effect of automatically controlling the operation in response to changes in the temperature and flow rate of the slag while maintaining the performance of the slag cooler.
