The support ring of the present invention is provided with a drive shaft at a point where it meets a horizontal line passing through a center point of the weight, A support ring for a converter for rotary kilns equipped with a rotary shaft, wherein the ring is connected to a hook suspended from a wire rope end of a hoisting machine, such as a crane, so that the rotary support ring can be turned, It is characterized by a support ring for a converter tank.

Description

TRUNNION RING FOR VESSEL OF CONVERTER "

The present invention is intended to provide a manufacturing facility for a tundish container support ring that supports the tundish container tilted toward the tapping port to pour out the tundish contained in the converter.

A converter used as a steelmaking facility is a steelmaking furnace that refines molten steel that has been melted in a blast furnace, that is, a furnace for converting molten pig iron taken out of a blast furnace into molten steel. Pour out the waste through a complete flipping operation of the support ring (Trunnion ring).

The luggage compartment support ring is provided with a cone link and a lug. The lug is attached to an outer surface of the support ring to perform a function of a leg for a flip. The cone link supports a retention container, The tapered tapered pipe is tilted in the direction of the tapping hole and is supported in a three-way distributed manner as a connecting link for supporting refined molten steel. The tapered container is tilted at a desired angle in a desired direction, It is a joint that supports it.

Patent No. 1180224 is an example of a converter. In order to ensure the convenience of manufacturing and assembling work and the stability of the product quality, the support ring of the hopper is turned upside down together with the lower half of the hopper. As shown in Fig. 1, on both sides of the hearth vessel supporting ring 1, a long long shaft 2 and a short shaft 3 are attached. That is, the long shaft 2 is used for tilting or straightening the waste container, and the short shaft 3 synchronizing with the drive shaft on the opposite side of the long shaft 2. These shafts are attached to each other on a single line transversely to the center of gravity of the hopper support ring and are mounted on the bearing of the frame mounted on the ground or hanging on a heavy vehicle such as a ceiling crane. Conventionally, as shown in FIG. 1, a lug (LUG) 4 is attached to the outer circumferential surface of the retainer ring support ring 1 as a separate operation at the time of a turn-over operation, and after the operation, Remove the lug (4) again. The lug 4 is used as a lifting ring of the hearth container supporting ring 1 or as a stopper (stopper) which is fixed to the ground during the flipping operation. As described above, in the conventional converter assembling process, in order to assemble the support for the waste container, the lugs are attached by the welding operation every time the operation is performed, and the operation of melting the waste liquor by melting it again is troublesome so that the process is slow and additional costs are incurred. There is a problem of thermal deformation due to welding heat.

An object of the present invention is to provide a support ring for a converter tank for a converter which can easily be reversed even without excluding lugs and prevent quality deterioration.

A supporting ring for a converter for a converter for a converter having a long axis in a transverse direction and a short axis synchronous with the long axis at a point where it meets a horizontal line passing through a center point of the weight on the outer circumference, With the idle ring formed in the long and short shafts so that the trash receptacle support ring can be turned as if the mandrel is turned in the state of being rotated.

In the present invention, the idle ring sandwiched between the long shaft and the short shaft is similar to a bushing which is easy to rotate freely. Crane and other heavy equipment, it is possible to freely and tilted the trench container at the correct angle and position with the long and short axes of the trench support ring supported by the weight chain.

In addition, since the lug for reversing is not provided in the lug holder support ring, the manufacturing cost is not incurred and the work for removing the lug is omitted. Thus, the manufacturing process is shortened and there is no fear of thermal deformation due to welding, There is no change.

Figure 1 is a perspective view of a conventional waste container support ring with a flip-
Fig. 2 is a plan view of a retainer ring supporting ring to which an idle ring of the present invention is applied
Fig. 3 is a front view of the support ring of the present invention in which the idle rings are fitted in the long and short axes
Fig. 4 is a detailed view of the ring part in Fig. 3
Fig. 5 is an illustration of an example of reversing the waste container support ring in a state in which the ring is hooked on the hook of the crane

2 and 3, a long shaft 2 and a short shaft 3 are attached to the outer circumferential surface of the hearth vessel support ring 1 of the present invention. In the state where the shaft is installed in the frame of the completed converter, Means that it is rotated by the means to support the tilting or standing straight.

In this retainer ring 1, the idle rings 5 and 6 are respectively fitted to the long shaft 2 and the short shaft 3 of the present invention. The idle rings (5, 6) can be used in a state of being fitted in a normal state, or can be mounted and used only when a lifting operation is required, and the shaft is assembled by loosening the shaft.

4, the idling rings 5 and 6 are fitted so as to be located as close as possible to the shaft roots of the long shaft 2 or the short shaft 3, that is, the outer peripheral surface of the hearth container supporting ring 1, 7) to stabilize the fitting state of the ring by stopping it from reaching the support ring (1).

The idle rings (5) and (6) are mounted on the inner surface with a lubricant such as grease or a lubricating means (8) such as an oilless material.

As shown in Fig. 5, the hook 9 of the crane is lowered and is hooked under the idling rings 5 and 6 to raise the tail pipe support ring 1. At this time, the lower end of the wire connected to the hook 9 is hooked on the idle rings 5 and 5 to lift it. It is safe that the impression is not higher than at least the outer radius of the rim support ring 1 so that it does not touch the ground when the rim support ring 1 is turned upside down.

When you have finished all subsequent work by turning over the trough support ring (1), lower the trough support ring (1) to the floor and remove the hook (9).

The idle rings (5, 6) of the present invention are collected and cleaned to prepare for the next use. The recyclability of the rings 5, 6 is also an advantage.
