Casting smelting furnace improved structure facilitating automatic pouring

Abstract

The invention discloses a casting smelting furnace improved structure facilitating automatic pouring. The casting smelting furnace improved structure comprises a heat preservation shell, a melting heating barrel, an overturning cover plate, a melting crucible and a flange cover. A lifting hydraulic rod is arranged in one side plate of the heat preservation shell, and the other side plate of the heat preservation shell is connected with the overturning cover plate through a hinge. The overturning cover plate is clamped between the annular edge and an annular protruding strip of the melting crucible. The annular edge is provided with a discharging channel and a discharging pipe. The flange cover is tightly connected with the annular edge through a screw. A swing rod is riveted to the top face of the annular edge, and the side wall of the annular edge is in contact with a swing hydraulic rod. According to the casting smelting furnace improved structure, the inclination angle of the melting crucible is controlled through the overturning cover plate, and the pouring speed of molten liquid is controlled. The swing rod and the swing hydraulic rod are used for driving the melting crucibleto swing, and the molten liquid in the melting crucible can be sufficiently and evenly shaken. The swing amplitude, the inclination speed and the angle of the melting crucible can be simply controlledthrough control over the lifting hydraulic rod and the swing hydraulic rod, and the casting smelting furnace improved structure is suitable for a casting assembly line for automatic pouring production.

Description

technical field [0001] The invention relates to the technical field of casting and smelting furnaces, in particular to an improved structure of a casting and smelting furnace which is convenient for automatic pouring. Background technique [0002] Throughout the casting process, the role of the gating system is to: control the speed at which the molten metal fills the mold and the time it takes to fill the mold; make the molten metal enter the mold smoothly, avoid turbulence and flushing of the mold; prevent Slag and other inclusions enter the cavity; no gas is involved during pouring, and the principle of sequential solidification should be followed as much as possible when the casting is cooled. [0003] However, the existing pouring system always uses a relatively complicated lifting mechanism to take out the heavy melting crucible from the smelting furnace before pouring, which has high requirements for the force structure of the lifting mechanism, and the ordinary lifti...

Problems solved by technology

[0003] However, the existing pouring system always uses a relatively complicated lifting mechanism to take out the heavy melting crucible from the smelting furnace before pouring, which has high requirements for the force structure of the lifting mechanism, and the ordinary lifting structure cannot meet the needs of automatic pouring , so it is necessary to change the way of taking out the crucible from the smelting furnace, that is, to propose a new improved structure of the casting smelting furnace
