Description
Technical Field
The application relates to metal smelting, in particular to a double-fulcrum induction intermediate frequency furnace.
Background
The induction intermediate frequency furnace is a vertical intermediate frequency furnace, and its steel structure mainly consists of furnace frame, furnace body, furnace tilting mechanism and furnace cover. The furnace type tilting furnace is realized by driving the furnace body to tilt and discharge by the tilting furnace mechanism. The position of the furnace shaft is important for calculating the tilting moment of the furnace, one method is to arrange the shaft near the center of gravity of the furnace, and the other method is to arrange the shaft near the furnace mouth. When the rotating shaft is near the center of gravity of the furnace body, the rotating radius from the furnace mouth to the rotating shaft is too large, so that the furnace mouth is likely to interfere with a ladle receiving molten iron. Therefore, most manufacturers set the rotating shaft near the furnace mouth, but considering the strength and rigidity problems of the steel structure and the realizability of the furnace tilting mechanism, the rotating shaft and the furnace mouth cannot be completely overlapped, so that the track change of the molten metal in the pouring process is large, and the requirements of some factories on small pouring amount and accurate pouring position of the molten metal cannot be met. A further problem is that the prior art hydraulic cylinder fulcrum is made on the furnace body and in order to provide sufficient torque, the fulcrum positions are all close to the center of gravity of the furnace body. The characteristic causes that the rotation radius of the fulcrum of the oil cylinder is large, and the working stroke of the oil cylinder is also large enough to meet the requirement of 95 degrees of overturning of the furnace body.
Even if the prior manufacturer realizes a small amount of accurate pouring process by tilting and discharging through double fulcrums, the service life of the mechanism is greatly shortened and even equipment faults can be caused due to abrasion of a rotating shaft of the furnace body.

The furnace frame (1) is provided with 2 rotating shafts, namely a first rotating shaft (101) and a second rotating shaft (102), wherein the position of the second rotating shaft (102) is on an arc track taking the first rotating shaft (101) as a rotating center and the straight line distance of the two rotating shafts as a radius. The first rotating shaft (101) and the second rotating shaft (102) on the furnace frame (1) are respectively corresponding to the first rotating shaft seat (202) and the second rotating shaft seat (203) on the furnace body (2) in position and are matched with each other. A third rotating shaft (103) is arranged on the furnace frame (1), and the third rotating shaft (103) is used for being connected with the furnace tilting mechanism (3). The furnace frame (1) is also provided with a fourth rotating shaft (104), and the fourth rotating shaft (104) is used for being connected with a hydraulic cylinder (302) on the furnace tilting mechanism (3).
The furnace body (2) is a carrier for smelting metal in an intermediate frequency furnace, and is internally provided with an inductor (not shown), a magnetic yoke (not shown), a hearth (not shown) and a furnace mouth (201). The furnace body (2) is provided with 2 rotating shaft seats, namely a first rotating shaft seat (202) and a second rotating shaft seat (203), wherein the second rotating shaft seat (203) is positioned on an arc track taking the first rotating shaft seat (202) as a rotating center and taking the linear distance between the two rotating shafts as a radius. A fifth rotating shaft (204) is arranged on the furnace body (2), and the fifth rotating shaft (204) is used for being connected with the furnace tilting mechanism (3). The furnace body (2) is provided with a furnace mouth (201), molten metal flows to the ladle through the furnace mouth (201), and after the furnace mouth (201) rotates to a specific angle along with the furnace body (2), the position of the furnace mouth (201) and the position of the second rotating shaft seat (203) are overlapped in two parallel planes. When the device is in an initial position, namely, the first rotating shaft seat (202) is overlapped with the first rotating shaft (101) on the furnace frame (1), and the second rotating shaft seat (203) is separated from the second rotating shaft (102) on the furnace frame (1). The first rotating shaft seat (202) and the first rotating shaft (101) form a hinge mechanism, and the furnace body (2) can freely rotate in a plane by taking the hinge mechanism as a rotating center. After the equipment rotates by a certain specific angle, the second rotating shaft seat (203) takes the first rotating shaft seat (202) as a rotating center, rotates to be overlapped with the second rotating shaft (102) on the furnace frame (1) to form a new hinge mechanism, at the moment, the first rotating shaft seat (202) and the first rotating shaft (101) are gradually separated, and the furnace body (2) continues to rotate to a final position by taking the second rotating shaft seat (203) as the rotating center.
