Description

[Detailed Description of the Invention] The present invention relates to a vibration forming device that effectively forms lining material supplied to a molten metal container such as a blast furnace tap trough or trough.

Recently, vibration molding or casting molding has been used to line the containers as described above, particularly for the purpose of saving labor.

FIG. 1 shows the conventional device, in which a core 2 equipped with a number of vibrators 5 is fixed to a frame 6 in a molten metal container 1, and is installed at a predetermined position of the core 2. After the lining material 4 was supplied between the core 2 and the core 2, the vibrator 5 was operated to vibrate the core 2 to fill the lining material 4.

However, the conventional device has the following problems.

The problem is as follows. (1) Since the vibrators 5 are installed over the entire surface of the core 2, a large number of vibrators 5 are required; (2) the simultaneous operation of the vibrators 5 causes extremely high noise; (3) a large number of vibrators (4) As the size of the container 1 increases, the lining material 4 becomes thicker, and the distance of vibration transmission to the lining material 4 increases, which reduces the construction time. (5) Since the entire lining material is vibrated, buoyancy is applied to the core 2 at once, and a large weight 8 is required to counter this. The core 2 is fixed to a frame 6 that bridges the molten metal container 1, and the core 2 is positioned inside the container 1, and the frame is moved along the wall of the container 1 or the core 2. A transfer mechanism 10 is provided at the lower part of the body 6, a diaphragm 3 provided on the transfer mechanism 10 is suspended between the container 1 and the core 2, and a vibrator 5 is attached to the diaphragm 3.
This is a vibration molding device characterized by being provided with.

The description will be given below based on the drawings.

1 is a molten metal container to be lined, and if it is a new construction, there is usually a permanent brick lining, and if it is a repair construction, the lining material after melting and damage remains on the inside. are doing.

A core 2 forms the inner surface shape of the lining material 4, and is installed on a frame 6 bridging the top of the container 1, and is supported within the container 1 with a gap corresponding to the thickness of the lining material 4.

A relatively small weight 8 is placed on the top of the frame 6 to counteract the buoyant force generated in the lining material 4 during vibration molding.

Furthermore, a transfer mechanism 10 for transferring a diaphragm 3 equipped with a vibrator 5 in the longitudinal direction of the container 1 is provided on both sides of the core 2 on the lower surface of the frame 6.

This transfer mechanism is composed of, for example, a roller 11 and a support 12, and the diaphragm 3 is fixed to the lower part thereof via a vibration-preventing shock absorber 9.

In this way, the transfer mechanism 10 in which the diaphragm 3 is set is pulled at an appropriate speed by a rope 13 or the like by the operation of a motor (not shown), moves through the lining material 4 supplied to the container 1, and moves the vibrator 5. The vibrations are transmitted to the diaphragm 3, and the vibrations are applied to the lining material 4 from the inner and outer surfaces of the diaphragm 3, thereby effectively performing lining construction in sequence.

The above-mentioned diaphragm 3 has the strength to hold the vibrator 5, and the diaphragm 3.3', 3 when moving inside the supplied lining material 4.
” should be strong enough to prevent meandering.

The shape of the diaphragm 3.3', 3'' can be determined arbitrarily depending on the lining material 4, but it is preferable to use one that approximates the cross-sectional shape of the core 2, and the one shown in FIG. The lower part of the plate 3 is freely connected by a shaft part 7 to prevent canceling and attenuation of vibrations from the diaphragms 3 on both sides, and when this diaphragm 3 is used, the bottom of the container It is suitable for molding both sides integrally.

In FIG. 4, the lower ends of the diaphragms 3' on both sides are formed into a semicircular arc shape, and are connected to the transfer mechanism 10 independently, and in FIG. This vibration molding device is equipped with a linear-shaped diaphragm 3'' suitable for lining only the upper side surface of the diaphragm.

Furthermore, although the above embodiment is an example in which one or a pair of diaphragms are used, these may also be arranged in a complicated manner.

Furthermore, with the embodiments shown in FIGS. 4 and 5, it is possible to repair one side at a time.

Since the present invention is a vibration molding device configured as described above, the lining is sequentially applied while applying vibration partially and effectively from the approximate or middle position of the lining material 4, so that it has many effects as described below. play.

(1) Construction can be done using fewer vibrators.

(2) The noise during vibration molding has become extremely low.

(3) Since the diaphragm passes through the material, the vibration transmission distance of the diaphragm is small and the vibration filling speed is faster.

(4) Since a vibrator is not attached to the entire surface of the core, the core only needs to be strong enough to serve as a formwork, making it easier to handle as it is lighter.

(5) Since the lining material is vibrated partially and sequentially, the buoyancy generated in the core is reduced, and the weight of the weight can be significantly reduced.
