Example one

As shown in figure 1, the novel prefabricated lining furnace for the low-pressure heat preservation furnace comprises a furnace mouth lining piece, a neck lining piece, a waist lining piece, a tail lining piece, a bottom lining piece, a middle assembly, a lining groove and an arc-shaped slope, the furnace mouth lining piece and the neck lining piece are connected through an arc-shaped interface, a waist lining piece and a tail lining piece are further distributed on one side of the neck lining piece away from the furnace mouth lining piece, the waist lining piece is connected with the neck lining piece through an arc-shaped interface, the tail lining piece is communicated with the waist lining piece through the arc-shaped interface, the right side of the tail lining piece is also connected with a bottom lining piece through an arc groove, the adjacent bottom lining pieces are connected through a middle assembly, the lining furnace formed by the lining parts is a half lining furnace, two identical half lining furnaces are combined to form a whole lining furnace mold, a blank in a high-temperature molten state is injected into the mold, and the mold is opened after cooling to obtain a formed prefabricated part.

In the present example, the lining material used was high-purity alumina, the alumina content of which was 94% or more and 0.6% or less of SiO 2. Establishing a three-dimensional model according to the geometric dimension of the low-pressure holding furnace, designing a corresponding mold, finishing pouring in a production workshop, baking to discharge the moisture in the mold, pre-assembling the prefabricated part before leaving a factory to ensure smooth installation on site, filling the backing of the low-pressure holding furnace with a high-strength dry material, ensuring that the moisture in a furnace lining is only the moisture in the air and can be discharged only by preheating 5 days before the low-pressure holding furnace is put into production, and enabling the low-pressure holding furnace to be put into production condition. The hydrogen content in the produced aluminum casting is consistent with the hydrogen content in the aluminum water entering the low-pressure furnace. The influence of the furnace lining of the holding furnace on the hydrogen content in the aluminum water of the aluminum casting is reduced to zero.

When the embodiment works, the lining pieces are spliced into the integral lining furnace mold, the high-temperature molten liquid of the prefabricated part is injected through the mold opening, then the pouring is finished in a production workshop, then the prefabricated part is baked to discharge the water in the prefabricated part and then is cooled to room temperature to be taken out, and the hydrogen content in the obtained aluminum casting prefabricated part is consistent with the hydrogen content in the aluminum water entering the low-pressure furnace. The influence of the furnace lining of the holding furnace on the hydrogen content in the aluminum water of the aluminum casting is reduced to zero, and the method is very convenient.
