The specific embodiment
The present invention evenly promotes aluminium ingot casting temperature by changing the flow-guiding structure form, reaches abundant elimination ingot casting internal residual stress, makes structural constituent even.
As shown in Figure 1, aluminum billet soaking pit furnace, under furnace roof 5 thermals treatment zone, resistance heater 2 is installed, resistance heater 2 is used for furnace air and is rapidly heated, the upper left side of furnace side wall 7 is equipped with left side circulating fan 1, the upper right side of furnace side wall 7 is equipped with right side circulating fan 6, and left side circulating fan 1 and right side circulating fan 6 are used to force furnace air to circulate; Right side circulating fan 6 is relative with left side circulating fan 1, and the horizontal air port of right side circulating fan 6 and the horizontal air port of left side circulating fan 1 all are right against heater 2, between heater 2 and aluminium ingot casting 8, be provided with horizontal guiding device 3, horizontal guiding device 3 is used for resistance heater and the aluminium ingot casting is separated by, and forms gas channel; Be provided with vertical guiding device 4 at the inboard of furnace side wall and below being positioned at the vertical air port of right side circulating fan, be provided with vertical guiding device at the inboard of furnace side wall and below being positioned at the vertical air port of left side circulating fan, vertical guiding device is used for the furnace high-temperature air stratification time is circulated.
As shown in Figure 2, horizontal guiding device 3 comprises horizontal deflector 33, bending shaped steel 32 and suspender member 31, bending shaped steel 32 is arranged on the horizontal deflector 33, horizontal deflector 33 is connected with suspender member 31 by connector 34, suspender member 31 hangs on the furnace roof below, and horizontal deflector 33 is between heater and aluminium ingot casting.
As shown in Figure 3, vertical guiding device 4 comprises bending angle steel 41 and wind deflector 42, bending angle steel 41 is connected to form skeleton structure, wind deflector 42 is set in skeleton structure, wind deflector 42 arranges that by different level the epimere of wind deflector 42 is straight plate, and hypomere is an arc, divide three layers and be arranged on the skeleton structure, internal layer to outer arc section radian from small to large; Skeleton structure is connected and fixed by connector 43 and furnace side wall, and connector 43 is made of microscler screw rod and nut, changeing and overhauling with convenient whole vertical guiding device.
