Water cooling system with uniform cooling effect for aluminum ingot production

Abstract

The invention discloses a water cooling system with a uniform cooling effect for aluminum ingot production, and relates to the technical field of aluminum ingot production. The water cooling system comprises a cooling tank, a water storage tank, a cooling-water machine, a first water pump, a circulating pipeline, a second water pump and a water conveying pipeline. The water temperature is adjusted through the cooling-water machine, intake water is sent into the water storage tank after the temperature of the intake water is controlled to be the set temperature, cooling water in the water storage tank can be rapidly cooled, and the temperature is constant; a monitoring module is used for monitoring and analyzing the working environment information in the cooling box to obtain a cooling coefficient; a controller automatically acquires a corresponding preset cooling scheme according to the cooling coefficient and controls a sprayer to control cooling water to flow out according to the corresponding preset cooling scheme, so that the cooling effect is improved; and by arranging the first water pump and the circulating pipeline, cooling water used in the cooling box can be conveniently pumped out and guided into the water storage tank to be collected, so that cyclic utilization treatment is facilitated, and the utilization rate of a water source is increased.

Description

technical field [0001] The invention relates to the technical field of aluminum ingot production, in particular to a water cooling system for aluminum ingot production with uniform cooling effect. Background technique [0002] At present, in the production process of aluminum ingots, the recycled waste aluminum is firstly cleaned and dried, and then the aluminum block is melted into aluminum liquid in a melting furnace, and the aluminum liquid is injected into the aluminum ingot cavity through the ingot casting machine to cool and form Finally, the formed aluminum ingot is removed from the mold. In the process of injecting molten aluminum into the aluminum ingot mold cavity through the ingot casting machine for cooling and forming, the cooling equipment adopts several spray nozzles above the aluminum ingot mold, and the water at the spray nozzle sprays the aluminum The ingot is cooled, but this process will inevitably produce a large amount of water vapor, which will increa...

Problems solved by technology

[0004] However, in this patent, the temperature of the water entering the cooling box through the sprayer cannot be adjusted, and it is difficult to cool the aluminum ingot to a suitable temperature, and the used water is generally lost directly, which cannot be recycled, which wastes water resources, and It is impossible to monitor and adjust the flow rate of the water sprayed by the sprinkler. When the water flow rate is too fast and the red-hot aluminum ingot touches the water flow, the cooling water will be heated to vaporize and immediately form a layer of steam on the surface of the aluminum ingot. This layer of steam The thermal conductivity of the film is very low, the heat of the aluminum ingot is mainly transferred out through the radiation and conduction of the steam film, and the cooling speed of the aluminum ingot is relatively slow at this stage
