[0002] The residual aluminum box body 1 is an iron box 3 with a steel frame structure outside (such as figure 1 and 2 As shown), the inner surface of the iron box is a layer of refractory material layer 2 with a thickness of 4±1cm. The refractory material layer 2 is mainly composed of refractory cement, high-temperature refractory sand and water. It needs to be dried naturally and baked before it can be used. , when the traditional natural gas method is used to bake the moisture and moisture on the inner wall of the residual aluminum box, a large amount of natural gas is consumed, which increases the economic cost of baking the residual aluminum box, and the use of natural gas for baking will cause the local temperature to be too high, due to thermal expansion and cooling The cause of shrinkage causes the refractory material layer 2 inside the residual aluminum box to crack, thereby shortening the service life of the residual aluminum box

Embodiment 1

[0020] Such as Figure 1-2 Shown, a kind of baking method of residual aluminum box comprises the steps:

[0021] (1) Sprinkle talcum powder evenly on the inner surface of the newly applied iron box for 2 days for curing. The talcum powder plays an isolation role, which can facilitate the complete removal of aluminum slag in step (2) and make the drying effect better;

[0022] (2) Sprinkle 600°C aluminum slag evenly on the inner surface of the cured residual aluminum box, and make the amount of aluminum slag half the volume of the residual aluminum box. After 16 hours, take out the residual aluminum (at this time, the residual aluminum box Inner aluminum slag is solidified), repeat this step twice, that is, the cumulative drying time is 48 hours, and at the same time, professionals use temperature measuring devices to measure the temperature around the outside and bottom of the residual aluminum box every 2 hours. The internal temperature is 170-230°C, and at 16 hours, the tem...

Embodiment 2

[0025] Such as Figure 1-2 Shown, a kind of baking method of residual aluminum box comprises the steps:

[0026] (1) Evenly spread talcum powder on the inner surface of the newly applied iron box for 3 days of maintenance;

[0027] (2) Sprinkle the 640°C aluminum slag evenly on the inner surface of the cured residual aluminum box, and make the amount of aluminum slag equal to half the volume of the residual aluminum box. After 15 hours, take out the residual aluminum and repeat the above steps Twice, that is, the cumulative drying time is 45 hours. At the same time, professionals use temperature measuring devices to measure the temperature around the outside and bottom of the residual aluminum box every 2 hours. The temperature is 170-230°C within 15 hours, When the temperature is 165°C, take out the aluminum slag, which is the aluminum slag produced by the slag breaking post, and the temperature measuring device is an infrared laser thermometer;

[0028] (3) Lightly tap the...

Embodiment 3

[0030] Such as Figure 1-2 Shown, a kind of baking method of residual aluminum box comprises the steps:

[0031] (1) Evenly spread talcum powder on the inner surface of the newly applied iron box for 2.5 days of maintenance;

[0032] (2) Sprinkle aluminum slag at 560°C evenly on the inner surface of the cured residual aluminum box, and make the amount of aluminum slag equal to half of the volume of the residual aluminum box. After 17 hours, take out the residual aluminum and repeat this step. Twice, that is, the cumulative drying time is 51 hours. At the same time, professionals use temperature measuring devices to measure the temperature around the outside and bottom of the residual aluminum box every 2 hours. The temperature is 170-230°C within 17 hours, and the temperature is , the temperature was 168°C, and the aluminum slag was taken out, the aluminum slag was the aluminum slag produced by the slag breaking post, and the temperature measuring device was an infrared laser...

Abstract

The invention discloses a method for baking residual aluminum boxes, which comprises the following steps: (1) uniformly spreading talc powder on the inner surface of the newly applied iron box for 2‑3 days of curing; The aluminum slag is evenly sprinkled on the inner surface of the cured residual aluminum box, and the amount of aluminum slag is half of the volume of the residual aluminum box. After 15‑17 hours, the residual aluminum is taken out, and this step is repeated twice. At the same time, professionals use a temperature measuring device to measure the temperature around the outside and bottom of the residual aluminum box every 2 hours, and replace the aluminum slag in time when the temperature is lower than 170°C; (3) Lightly tap the inner surface of the residual aluminum box with a wooden hammer without falling off , no grooves and no cracks to complete the baking of the residual aluminum box; this method can not only save costs, but also ensure the service life of the residual aluminum box, and is safe and effective at the same time.
