Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lining and refractory material-flowing construction device such as a tundish in refractory construction.

[0002]

[Prior Art]

 Conventionally, when lining an indeterminate refractory material on the inner wall or bottom of a tundish, etc., a flexible container of the irregular refractory material is conveyed to the mixer by the crane, and the irregular refractory material mixed by the mixer is belted. It is loaded into a hopper that can be driven by a trolley via a conveyor, and is poured from the discharge shoe of the hopper into the inner circumference of the tundish with the core as a framework.

When the amount of the irregular refractory loaded in the hopper has been discharged, the operator operates the rod-shaped vibrator to vibrate the poured irregular refractory to flow-fill it. ing. By repeating such work, the upper surface of the tundish was filled with the amorphous refractory and the construction was performed.

[0004]

[Problems to be solved by the device]

 However, in the conventional lining refractory distribution equipment, since the hopper cart travels only in the length direction of the tundish, only a linear single-shaped tundish can be effectively used, and a complicated shape is required. It was of little value when using tundish or tundish of two or more shapes.

In addition, the vibration work is carried out by a worker holding a rod-shaped vibrator, and there is a problem that the number of personnel is increased compared to the brick-laying work.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of the above points, and in order to solve the above-mentioned problems, a hopper is mounted on a traveling carriage to a molten metal container such as a tundish, and an amorphous refractory is removed from the hopper. In a lining refractory material pouring equipment such as a tundish that is pouring construction, a hopper is arranged on a traveling carriage so as to be controllably movable in the longitudinal direction of the molten metal container such as the tundish and in a direction orthogonal thereto. The hopper installed on the traveling carriage vibrates, and a vibrator that excites the poured refractory is installed in the hopper or traveling carriage. To provide the equipment.

[0007]

[Action]

 When the tundish lining is constructed using the refractory distribution equipment for lining according to the present invention, the hopper is arranged on the traveling carriage so that the movement of the hopper can be controlled in the longitudinal direction of the tundish and the direction orthogonal thereto. -It is possible to move not only in a straight line but also in a wide range, and it is possible to easily cast amorphous refractory into a tundish of complicated shape or tundish of two or more shapes.

Further, since a vibrator for vibrating the hopper or vibrating the poured refractory material is provided in the hopper or the traveling carriage, the personnel for vibrating the poured refractory material can be provided. It can be deleted, saving labor and reducing the cost of refractory distribution.

【Example】

 Hereinafter, the present invention will be described based on embodiments. 1 and the following, the present invention will be described based on an embodiment. An embodiment of the present invention will be described below with reference to FIG. The tundish 1 has a shape as shown in FIG. 1 and FIG. 2, and the lining refractory distribution device 2 has a hopper-3 for pouring an indefinite refractory material mounted on a traveling carriage 4 to form a tundish 1. By moving in the longitudinal direction of the tundish 1 and its orthogonal direction, the irregular shaped refractory is poured into the inner peripheral portion of the tundish 1 so that the tundish 1 can be lined.

As shown in FIGS. 1 and 2, the traveling carriage 4 is mounted on the traveling rails 5 arranged on both sides of the tundish 1 along the longitudinal direction of the tundish 1 so that the traveling drive can be controlled. .. Then, a traveling rail 6 is arranged on the traveling carriage 4 installed between the tundishes 1 in a direction orthogonal to the longitudinal direction of the tundish 1, and the hopper-3 is driven along the traveling rails 6 for drive control. The hopper 3 is freely mounted and can be freely moved in the longitudinal direction of the tundish 1 and the direction orthogonal thereto by a traveling drive device (not shown) such as a servo motor as described above. ..

As shown in FIG. 3, such a hopper 3 has an inverted conical shape with a predetermined capacity, and its side peripheral portion is supported by the traveling carriage 4 by a plurality of spherical bearings 7 and the like so as to be rotatable. Further, a gear engaging mechanism 9 is provided on the peripheral portion of the pouring portion 8 of the cast refractory of the hopper-3 so that the turning drive device 10 such as a servomotor can control the turning drive at a predetermined angle. The discharge shunt 11 disposed eccentrically at the lower portion is directed in an appropriate direction so that the casting work can be performed smoothly over as wide a range as possible.

Further, as shown in FIG. 3, a vibrator 12 of a rod-shaped vibrator is attached to an elevating device 13 so as to be able to move up and down on a side peripheral portion of the hopper-3, and a discharge shoe 11 of the hopper-3 is installed. Following the opening and closing of, when the refractory poured from the discharge shoe 11 is poured into the tundish 1, the vibrator 12 of the rod-shaped vibrator is lowered according to a preset pattern and the poured refractory is fired. Items are vibrated so that they can be fluidized and filled.

Further, as shown in FIG. 3, a vibrator 14 of a vibration motor is arranged in the discharge shoe 11 of the hopper-3, and the discharge shoe 11 is vibrated to make the irregular refractory material. I am trying to pour it into the tundish 1 smoothly. Reference numeral 15 is a damper, 16 is a damper opening / closing device, and 17 is a core vibration motor that vibrates the bottom of a core 18 framed inside the tundish 1.

Further, a mixer 19 is arranged on the side of the tundish 1 as shown in FIG. 1 and FIG. 2, and an irregular refractory material charged from a flexible container 21 is kneaded by a crane 20. The hopper 3 can be loaded by the extendable belt conveyor 22.

In the tundish 1 thus arranged, data for lining construction such as positions and depths of a plurality of positions in a longitudinal direction and a direction orthogonal to the longitudinal direction are input to a control device such as a computer in advance. Then, the traveling carriage 4 and the hopper-3 are automatically driven and controlled along the traveling rails 5 and 6 by the sequential control or the program control of the predetermined lining pouring pattern, and the rod-shaped vibrator is driven. The tundish 1 and the other vibrators 12 and 14 are automatically operated so that the tundish 1 can be automatically poured with an irregular refractory material for lining work.

Therefore, as shown in FIG. 2, when the poured refractory material is kneaded through the mixer 19 and the belt conveyor 22 into the hopper-3 and the hopper-3 is operated based on the setting, the traveling carriage 4 is operated. Then, the hopper-3 moves along the traveling rails 5 and 6 in accordance with a predetermined pattern, and if necessary, the hopper-3 is rotated by a predetermined angle, so that the tundish 1 and the core 18 are separated from each other. The refractory is poured into the space between the two, and the discharge shoe 11 is oscillated by the vibrator 14, and the rod-shaped vibrator 12 is advanced by an appropriate amount according to the setting and lowered to the timer. For example, the fluid is filled by vibrating sequentially for a predetermined time.

In this way, the tundish 1 can be lined by filling and discharging the tundish 1 by repeatedly discharging and vibrating the amorphous refractory material several times. Then, when the appropriate amount is filled, the core vibration motor 17 installed in the core 18 is activated to vibrate the core 18, and the flow-filled poured refractory material is degassed to be filled. It is a thing.

Therefore, even if the tundish has a complicated shape in which the side circumference is curved, the hopper can be freely moved and controlled along the shape of the tundish, so that the refractory having an irregular shape can be automatically poured. Can be lined.

Further, even if a tundish of different shape is arranged, the hopper is moved not only in the longitudinal direction of the tundish but also in the direction orthogonal thereto, so that the hopper can be moved in a wide range. The tundish lining can be effectively implemented.

Although the tundish has been described above, it can be similarly applied to a large molten metal container such as a blast furnace gutter.

[0021]

[Effect of the device]

 As described above, according to the present invention, since the hopper can be controlled to move in the longitudinal direction of the molten metal container such as a tundish and the direction orthogonal thereto, a tundish having a complicated shape or two or more shapes Even in the case of alternate construction, it is possible to automatically pour the refractory material and improve the construction efficiency.

Further, since a vibrator is provided on the traveling carriage and the hopper to vibrate the hopper and vibrate the poured refractory, the number of personnel required for vibrating work can be reduced and labor can be saved. Even if it is hot, the lining work can be performed and the working environment can be improved.
