[0002] A pig casting machine is a device for casting molten iron produced by an ironmaking blast furnace into iron blocks of a certain shape. The temperature of the molten iron during pouring is generally 1250 - 1300 °C. The pig casting molds filled with molten iron move slowly along with the transmission chain, and the iron blocks in the pig casting molds gradually cool until the end of the chain belt. If the temperature of the iron blocks needs to be reduced to the required value within the time from the transmission chain to the end, it is necessary to accelerate the cooling speed of the cast iron blocks, and a spray cooling device is required to cool them down.

At the same time, there is a lack of standby water supply. When the water pump is damaged or the water supply system is damaged, it is inconvenient to carry out the spray cooling operation;
