The specific embodiment
Referring to Fig. 1, induction melting equipment with the burner casting of the present utility model is comprised of smelting furnace 1 and furnace end device 7, but furnace end device 7 is installed in the cast gate 2a place of described smelting furnace 1 in the mode of automatic open-close, and airtight connection the between furnace end device 7 and the smelting furnace 1.Smelting furnace 1 is comprised of furnace lining 2, cast gate 2a, the steelframe supporting construction 4 that is installed in furnace lining 2 outsides, turndown oil cylinder 5.The effect of smelting furnace 1 is the melted alloy furnace charge, and the effect of bell 3 is to capture flue gas, and the effect of furnace end device 7 is the effects that turn cast alloy liquid of playing when casting.
Furnace end device 7 partly is comprised of vert cylinder 9, cylinder seat 9a, the burner rotating shaft 10 etc. of burner 7a, stove top 8, burner; Stove top 8 can be used as an integral body with cast gate 2a and pours into a mould, builds by laying bricks or stones, and the hollow pipeline that forms between the two is aluminium alloy metaideophone passage.Two kinds of connection status are arranged between furnace end device 7 and the smelting furnace 1, in alloy melting process and the boiling hot burner process, be connected as a wholely between furnace end device 7 and the smelting furnace 1, action between the two and keeps close contact between furnace end device 7 and the smelting furnace 1 synchronously.Finish scald the burner process after, separate between furnace end device 7 and the smelting furnace 1, smelting furnace 1 can vert, batch turning, furnace end device 7 turns the aluminium alloy of pouring out in the casting smelting furnace 1.
Burner 7a is fixed on the cylinder seat 9a by burner rotating shaft 10, and a vert end of cylinder 9 of burner is fixed on the cylinder seat 9a, and the other end is fixed on the burner 7a.Cylinder seat 9a can be rapidly realizes being connected, separating two states with smelting furnace 1, realizes being connected between furnace end device 7 and the smelting furnace 1, simultaneously operating, and separate, independent operation, for example can, by oil cylinder press independently.
Be connected between furnace end device 7 and the smelting furnace 1 when as a whole, burner cylinder 9 elongations of verting, burner 7a is along burner rotating shaft 10 rotations, and suitable for reading and stove top 8, the cast gate 2a of burner 7a fit tightly, and see Fig. 1.
Furnace lining 2 is closed by a movable lid 3, is stove top 8 between cast gate 2a and the burner 7a, and bell 3, stove top 8 all use the casting type fire-resistant material heat insulation; Furnace lining 2, cast gate 2a, bell 3, stove top 8, burner 7a surround an airtight space jointly, and smoke discharging pipe links to each other with bell (not marking among the figure), and are connected (not shown) with pipeline with outside flue gas purification system by swivel joint.Depositing 11, stopper 12, handle 13 are installed on the burner 7a, and when melting and boiling hot burner, stopper 12 is blocked depositing 11; When casting, by the aluminium alloy flow in handle 13 and the stopper 12 control depositings 11.
After alloy melting finishes, when the alloying component in the smelting furnace 1 is adjusted to when meeting technological requirement, because furnace end device 7 has been connected as a whole with smelting furnace 1, at this moment, 5 elongations of turndown oil cylinder, smelting furnace 1, bell 3, furnace end device 7 vert to the right synchronously, and aluminium alloy 6 flows among the burner 7a by cast gate 2a, keeps 2-4 minute; Turndown oil cylinder 5 shrinks, smelting furnace 1, bell 3, furnace end device 7 vert left synchronously and reset, and the aluminium alloy among the burner 7a flows back in the smelting furnace 1, so repeatedly verts 3-5 time, can utilize copper liquid in the smelting furnace with the temperature increase of burner 7a to the casting technique requirement, see Fig. 2.
After scalding the end of burner process, aluminium alloy temperature in the smelting furnace is raised to the technological requirement of coming out of the stove; Subsequently, furnace end device 7 separates with smelting furnace 1, and vert cylinder 9 of burner shrinks, and burner 7a is along burner rotating shaft 10 to right rotation, and separate on the suitable for reading and stove top 8 of burner 7a, the composition surface of cast gate 2a, and furnace end device 7 is returned to normal casting position; Turndown oil cylinder 5 rises smelting furnace 1 again, and aluminium alloy 6 flows among the burner 7a by cast gate 2a, and by the aluminium alloy flow in handle 13 and the stopper 12 control depositings 11, casting device 14 can begin casting manipulations, sees Fig. 3.
Use the medium frequency induction melting furnace with the burner casting of the present utility model, utilize cast gate, bell, stove top, burner jointly to surround an airtight space, realize capture, the purification of melting flue gas; Utilize fume afterheat baking burner, cancelled heating, roasting procedure that chute, basket pouring need, saved fuel; Reduce alloy melting temp, reduced the oxidation, air-breathing of alloy melting, casting process, be conducive to improve the quality of casting and follow-up goods.
