Problems solved by technology

However, after this device stops casting for more than five hours, the infrared heater outside the box must be activated to guide hot air into the box for heating. This heating method is quite slow, and the maximum heating temperature in the box can only reach 450 degrees.
Therefore, it has two major defects, the heating time is long and the heating temperature cannot meet the requirements, which leads to the limitation of the casting process.

Embodiment Construction

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Such as Figure 1-2 As shown, the aluminum liquid heating device outside the box provided by this embodiment includes a vacuum degassing box 1. The two sides of the vacuum degassing box 1 are respectively provided with an aluminum liquid inlet and an aluminum liquid outlet. Closed ram 2, the outlet of the aluminum liquid is provided with an outlet fully-closed ram 3; the chamber of the vacuum degassing box 1 is provided with a middle semi-closed ram 4, which divides the chamber into two left and right chambers A 11 and B In the chamber 12, there is a gap between the bottom of the middle semi-closed gate 4 and the bottom of the vacuum degassing box 1, and an electromagnetic stirrer 5 is provided at the gap; a heater 6 is provided at the inlet of the molten aluminum.

[0017] The inlet fully enclosed ram 2 , the outlet fully enclosed ram 3 and the middle semi-close...

Abstract

The invention discloses an out-box molten aluminum heating device. The device comprises a vacuum degassing box, wherein a molten aluminum inlet and a molten aluminum outlet are arranged at the two sides of the vacuum degassing box; the molten aluminum inlet is provided with an inlet full closing gate plate; the molten aluminum outlet is provided with an outlet full closing gate plate; a middle half closing gate plate is arranged in a cavity of the vacuum degassing box for dividing the cavity into a cavity A and a cavity B at the left and right sides; a gap is left between the bottom of the middle half closing gate plate and the bottom of the vacuum degassing box; an electromagnetic stirrer is arranged in the gap; and a heater is arranged in the molten aluminum inlet. The out-box molten aluminum heating device has the following advantages: the electromagnetic stirrer is used for enabling the liquid level heights of molten aluminum in the cavities A and B to form a fall in the vacuum degassing box to cause the vacuum negative pressure so as to circulate the molten aluminum in the vacuum degassing box; after the molten aluminum in the cavity A is heated through the heater, the heat exchange is performed between the hotter molten aluminum and the colder molten aluminum under the effect of circulation of the molten aluminum in the cavity A.

Description

technical field [0001] The product of the invention belongs to the technical field of molten aluminum, in particular to a novel heating device for molten aluminum outside a box. Background technique [0002] The dynamic vacuum aluminum liquid dehydrogenation equipment is the most effective device in the purification of aluminum melt, and its dehydrogenation effect is 40% higher than the traditional dehydrogenation effect. However, after this device has stopped casting for more than five hours, the infrared heater outside the box must be activated to guide hot air into the box for heating. This heating method is quite slow, and the maximum heating temperature in the box can only reach 450 degrees. Therefore, it has the two major defects of long heating time and insufficient heating temperature, which lead to limitations in the use of the process during casting. Contents of the invention [0003] The technical problem to be solved by the product of the present invention is ...
