Casting molten metal smelting system and a mounting method thereof

Abstract

The invention provides a casting molten metal smelting system and a mounting method thereof. The mounting method comprises the steps that a crucible mold is prepared, the appearance shape of the crucible mold is consistent with that of a crucible, and the difference between the contour dimension of the shape of the crucible mold and the contour dimension of the shape of the crucible is a non-zeropositive real number; the crucible mold is placed in a heating device, furnace lining material is filled between the crucible mold and the heating device, the crucible mold is taken out, the cruciblemold is put into the crucible, and then refractory sand is filled between the crucible and a furnace lining; the casting molten metal smelting system comprises the heating device with an opening at one end and the crucible with an opening at one end, the crucible is sleeved in the heating device, the direction of the opening end of the crucible and the direction of the opening end of the heating device are consistent, and a refractory layer and the furnace lining are sequentially arranged between the outer wall of the crucible and the inner wall of the heating device from inside to outside. Byadopting the technical scheme, the furnace lining and the crucible are isolated through the refractory layer, burning damage caused to the furnace lining can be prevented after the crucible is damaged, the phenomenon of furnace leakage is avoided, the service life of the casting molten metal smelting system is prolonged, and the operation of replacing the new crucible is convenient.

Description

technical field [0001] The invention relates to the technical field of casting technology, in particular to a casting molten metal smelting system and an installation method thereof. Background technique [0002] Smelting molten metal is an important process in the casting process. The structure of the existing casting molten metal smelting system is as follows: figure 1 As shown, it includes a heating device with an open end and a crucible with an open end. The crucible is set inside the heating device and its opening ends are directed in the same direction. A furnace lining is arranged between the outer wall of the crucible and the inner wall of the heating device. Now After repeated use of some casting molten metal smelting systems, the wall of the crucible is gradually burned due to the long-term high temperature of the crucible, and its wall thickness becomes thinner and thinner. When part of the wall of the crucible is burned through, the molten metal It will enter th...

[0002] Smelting molten metal is an important process in the casting process. The structure of the existing casting molten metal smelting system is as follows: figure 1 As shown, it includes a heating device with an open end and a crucible with an open end. The crucible is set inside the heating device and its opening ends are directed in the same direction. A furnace lining is arranged between the outer wall of the crucible and the inner wall of the heating device. Now After repeated use of some casting molten metal smelting systems, the wall of the crucible is gradually burned due to the long-term high temperature of the crucible, and its wall thickness becomes thinner and thinner. When part of the wall of the crucible is burned through, the molten metal It will enter the furnace lining, further damage the furnace lining, and cause leakage, such as figure 2 As shown, and because the crucible wall material and furnace lining material are melted into the molten metal, when it is poured into a casting, it is easy to form slag inclusion defects in the casting. The crucible in the molten metal smelting system needs to be replaced. However, since the crucible wall and furnace lining have been damaged, it is inconvenient to replace the crucible.
