Problems solved by technology
[0003] In the past, the diversion structure of the soaking furnace was mainly composed of simple horizontal and vertical deflectors. The temperature of this structure was not uniform during the heating process of the aluminum ingot, which resulted in the inability to fully eliminate the residual stress and the composition of the structure.

Embodiment Construction
[0017] The invention improves the temperature of the aluminum ingot evenly by changing the form of the diversion structure, so as to fully eliminate the internal residual stress of the ingot and make the composition of the ingot uniform.
[0018] Such as figure 1 As shown in the soaking furnace for aluminum ingots, a resistance heater 2 is installed directly under the heating zone 5 on the furnace roof. The resistance heater 2 is used for rapid temperature rise of the air in the furnace. The fan 1 and the upper right side of the furnace side wall 7 are equipped with a right circulating fan 6, the left circulating fan 1 and the right circulating fan 6 are used to force the air in the furnace to circulate; the right circulating fan 6 is opposite to the left circulating fan 1 , and the horizontal air outlet of the right circulating fan 6 and the horizontal air outlet of the left circulating fan 1 are facing the heater 2, and a horizontal guide device 3 is arranged between the hea...

The invention provides an aluminum billet soaking pit furnace, a heater is arranged just below the heating area of the furnace top, a left circulating fan is arranged at the upper left side of the furnace side wall, a right circulating fan is arranged at the upper right side of the furnace side wall, the right circulating fan and the left circulating fan are opposite to each other, a horizontal air inlet of the right circulating fan and the horizontal air inlet of the left circulating fan are dead against the heater, a horizontal stream guidance device is arranged between the heater and the aluminum billet, a vertical stream guidance device is arranged at the inner side of the furnace side wall and is located below the vertical air inlet of the left circulating fan, and a vertical stream guidance device is arranged at the inner side of the furnace inner wall and is located below the vertical air inlet of the right circulating fan. Due to the stream guidance mode of the soaking pit furnace, air flowing and warming in the furnace is more uniform, air in the furnace is fully contacted with the billet, and the temperature rising speed of the billet is more rapid and uniform.
Description
technical field [0001] The invention relates to an aluminum ingot soaking furnace, in particular to an aluminum ingot soaking furnace with a novel flow guide structure. Background technique [0002] In the process of casting aluminum ingots, the internal chemical composition and structure of aluminum ingots will be uneven, and there are generally residual stresses inside. In order to eliminate the residual stress of ingots, eliminate the chemical composition and structure of ingots Inhomogeneity, to improve the pressure processing of the ingot and some final properties of the product, it is necessary to homogenize the ingot. The homogenization of ingots is generally carried out in the soaking furnace, and the diversion structure is an important part of the soaking furnace, which plays an important role in the entire work process of the soaking furnace. [0003] In the past, the diversion structure of the soaking furnace was mainly composed of simple horizontal and vertical ...
