Experimental example 2 the first furnace was charged with 35 Kg/ingot of aluminum, 1.5 tons, initial melting power of 148KW, melting time of 4 hours, temperature set point of 680 ℃, and complete melting. And pouring 0.5 ton of aluminum liquid, and then continuously adding 0.5 ton of aluminum ingot, wherein the smelting power is 143KW, and the smelting time is 64 minutes.
Comparing test example 1 and test example 2, it was confirmed that the melting was faster and less energy-consuming with 25kg of aluminum ingot than with 35kg of aluminum ingot.
In experimental example 3, 500Kg of aluminum ingot and 25Kg of aluminum ingot are added in the operation process, the set value of the melting temperature is 680 ℃, the melting power in the operation is 141KW, and the melting time after finishing the melting is 61 minutes.

Through the comparison of the tests, the 25kg specification of the aluminum ingot is determined. If the smelting temperature is set to 720 ℃ and the smelting power is 141KW, the smelting process can save about 3 min/time, but the electric energy consumption is basically the same, and the pressure of a subsequent cooling system is increased due to high temperature, so the temperature of the smelting furnace is preferably set to 680 ℃.
Test example 5
Under the technical conditions that 25kg of aluminum ingots are used, the smelting temperature is set to be 720 ℃, and the smelting power is 141KW, the total time required for smelting is about 3-4 hours.

However, the addition amount of the catalyst is more than the theoretical value (1 per thousand), and about 1.1 per thousand is required; and the reaction speed of the prepared aluminum alloy and water is slow: the time for the complete reaction of 30g of aluminum block with water was about 3 hours.
Considering that the casting time is 1-3h after the catalyst is added into the smelting furnace and poured into the holding furnace, the adding position of the catalyst is changed into the holding furnace, and the casting is completed within 1h after the catalyst is added into the molten aluminum. The product was subjected to hydrolysis experiments: the time for the complete reaction of 30g of the aluminum block with water was about 2.5h.
Through comparison of the test examples, the catalyst is preferably added into the heat preservation furnace, the adding amount of the catalyst is reduced to 1 per thousand, the cost is saved, and the time value of production operation is improved.
