Description

[Detailed Description of the Invention] The present invention relates to an apparatus for vibration forming the lining of molten metal/vessels such as ladles, blast furnace troughs, and tank pushers.

As a method of vibration forming the lining of a container as described above, a material is placed between the container and a core provided therein, and
There is a method of filling the material by applying vibration to the core, or a method of placing the material in a container and filling the material by causing the vibrated core to sink from above.

In these methods, when the thixotropy of the monolithic refractory used as the material is utilized, the material becomes fluidized by vibration during molding, exhibiting a physical phenomenon similar to that of a liquid, and buoyancy acts on the core.

Furthermore, buoyancy acts on the core even in the case of cast molding of an amorphous refractory material in which a large amount of water is added and a curing agent is added.

Therefore, as shown in FIG. 2, in the conventional vibration molding apparatus, the core 4 is attached to a frame 7 for positioning it in a container 6 with a space equal to the lining thickness, and a weight 2 is placed on the frame 7. , 2 are placed to prevent the core 4 from lifting up during molding.

In addition, in the above method, it is not easy to charge the material because the space between the container and the core 4 is narrow, so as shown in FIG. ing.

Each weight 2 is provided with a hook 3 to facilitate adjustment or movement of the weight 2, and a vibrator 5 is installed in the core 4 to impart vibration to the core 4, while a vibration isolating material 9 is used to prevent the vibrations of the core 4 from being transmitted to the frame 7.

The placement position of the weight in the conventional vibration molding apparatus is as described above, which poses a problem when an operator touches the container during molding to input material, observe the degree of filling of the material, and the like.

Furthermore, since this weight is divided, the entire device becomes large, making it extremely difficult to move the device before and after molding.

The present inventors considered installing the weight 2 inside the core 4, but when the heavy weight 2 was put in and taken out from the core 4, it would come into contact with the vibrator and damage it, or the vibrator would be damaged. There were problems such as the lack of space to adjust the amplitude, strength, etc.

The present invention has been made to solve the above-mentioned problems in the past, and aims to propose a vibration molding device in which the loading of refractory material is not hindered by the weights found in conventional means.

Then, in a vibration molding device in which a vibrator is installed inside the core, a removable weight is fitted in the center of the upper part of the core, and the head of the weight is tilted in a chevron shape to form a material chute. The purpose is to provide equipment.

An example of the implementation of the present invention will be described below in detail based on the drawings.

As shown in FIG. 1, a lining 18 is formed on a container 16 with a permanent lining 10 by the vibration forming apparatus A of the present invention, and the lower part of the apparatus A is the lining 18 to be obtained.
The external shape matches the internal surface of 8, and the cross section of this part is U.
It consists of a core 14 made of a tensile shell having a letter-like shape, and an appropriate number of vibrators 15 are installed inside the core 14 to vibrate the refractory material surrounding the outer periphery of the core 14.

Then, the core 14 is fixed to the frame 21, and the frame 21 is fixed to the frame 17 with the vibration isolating material 19 interposed therebetween, and is further installed on the base 23 using the legs 22.

By doing so, a space corresponding to the thickness of the lining 18 is provided between the core 14 and the permanent lining material 10 provided inside the container 16 if necessary.

Reference numeral 12 denotes a weight, which is detachably fitted into the center of the upper part of the core 14.

The head of the weight 12 is inclined in a chevron shape, and the inclined surface is used as a material chute, and a sub-chute 24 is fixed to the frame 17 to prevent the weight 12 from shifting due to vibration of the vibrator 15. However, by providing unevenness on the lower surface of the weight 12 so that they fit together, the weight 1
2 may be prevented from moving.

A hook 13 is provided on the weight 12 to facilitate the attachment and detachment of the weight 12 by a crane, and a guide 25 is also attached to prevent the fireproof material from escaping outside the container when being charged.

The shape of the weight 12, which is the main part of the present invention, has a chevron-shaped head and can be tilted at any angle, but it is sufficient that the material falls smoothly and evenly, and it can be used in long containers such as blast furnace gutter or tumble pusher. A roof shape is best for vibration molding equipment for commercial use, and a cone shape is best for containers with a circular outer circumference, such as ladles.

The vibration molding apparatus A configured as described above is configured so that when forming the lining 18 provided inside the container 16, a space corresponding to the thickness of the lining 18 is provided inside the permanent lining material 10 provided as necessary in the container 16. A is positioned, and when the material from the upper part of the weight 12 is dropped by a belt conveyor, a container bag (both not shown), etc., the material is distributed evenly at the top of the weight 12, and the material is distributed evenly at the top of the weight 12.
It slides down the slope formed on the ground and falls into the gap on the left or right or in the surrounding area.

At this time, if the vibrator 15 is driven, the falling of the material will be further promoted.

The material that has fallen into the space between the container 16 and the core 4 is removed by the vibrator 15.
The lining 18 is formed by driving the core 14, which is caused by fluidization due to thixotropy of the material.
The weight 12 prevents the object from floating up due to the buoyancy of the object.

As mentioned above, the device of this invention places the weight at the center of the upper part of the core, so it does not interfere with the work during lining molding, and since the weight also functions as a material chute that distributes the weight smoothly and evenly, the entire device The structure is simple, the equipment is easy to handle, and the efficiency of lining forming is improved. Furthermore, the progress of adding refractory material can be easily confirmed, which is excellent in terms of worker safety. It lists the results.
