Description

[0001] The present invention relates to an equipment load measuring apparatus and a tundish car including the same,

The present invention relates to an apparatus, for example, a tundish load measuring apparatus and a tundish car including the tundish load measuring apparatus, and more particularly, to a tundish car equipped with a hydraulic cylinder for aligning a tundish of a tundish, A tundish load measuring device including a load cell for measuring a load while moving by a predetermined distance by a tundish moving in a nozzle aligning operation, and a tundish car including the tundish load measuring device.

Measuring loads on equipment used in various industries is a very common task. The load of the equipment itself may be measured and the measured load value may be used for the repair work of the equipment or may be considered for connection with other equipment.

On the other hand, a facility that contains a specific substance in the interior initially measures the weight of the facility itself, measures the load of the facility in a state in which the specified substance is accommodated, adds or subtracts the initial load value of the facility, Is also widely used. In this respect, the work of grasping the load of a facility is a very basic task in various industrial fields.

Particularly, in continuous casting, there is used a method of measuring the load of the internal material by measuring the load of the internal material containing the specific material and subtracting the load value of the initial equipment.

Continuous casting refers to a casting method in which molten steel is continuously injected into a mold having a predetermined shape, and the semi-solidified cast product is continuously drawn to the lower side of the mold in the mold to produce semi-finished products of various shapes.

A continuous casting apparatus used in a general continuous casting process includes a ladle containing refined molten steel in a steelmaking process, a ladle turret for supporting and rotating the ladle and subsequent ladle, a tundish for temporarily storing molten steel supplied from the ladle, A vertical transfer roller for distributing the molten steel through the immersion nozzle of the tundish and performing a series of operations for solidifying the molten steel while solidifying the molten steel and solidifying the molten steel into a predetermined shape and solidifying the molten steel through the mold.

However, the strip casting technique recently applied is a combination of continuous casting and hot rolling. In the ordinary continuous casting method, the hot rolling process is omitted, and molten steel supplied from the nozzle of the tundish is injected into the casting roll To produce a sheet having a thickness of 2 to 6 mm directly. This is a technique that goes directly from casting to rolling, so that not only the production cost is reduced by shortening the process, but also the quality can be improved by rapid cooling.

In particular, the senz nozzles used in the above technique are different from the nozzles used in the mainstream continuous casting process. In the conventional continuous casting process, circular shaped nozzles are generally used, but the sen nozzles are formed as thin rectangular blocks so that the molten steel can be uniformly distributed evenly.

This is because, in the strip casting process, the molten steel is discharged from the casting rolls constantly without being drifted, which is a factor directly affecting the quality of the product. Therefore, it is effective from the viewpoint of the quality of the product to use the sen nozzle having the form of a thin rectangular block rather than the circular nozzle used in the prior art in order to discharge the molten steel uniformly without being drifted.

Since the flow of molten steel is a very important factor in the process of supplying molten steel, it is very important to control the amount of molten steel in the tundish and to prevent the abnormal flow of molten steel from being discharged due to eddy current Do.

First, in order to prevent abnormal flow of molten steel, it is necessary to precisely align and fasten the positions of the sen nozzles coupled to the molten steel outlet of the tundish. Normally, a device called a tundish car used to support the tundish is adjusted, You can sort the locations.

That is, a hydraulic device is built in the tundish car so that the tundish can be moved up or down or in the horizontal direction of the casting. It is possible to adjust the vertical position of the casting roll by aligning the center position of the casting roll and the center nozzle by rotating the wheel located at the lower end of the tundish to adjust the position of the casting roll.

In addition, in order to keep the amount of molten steel in the tundish constant in the continuous casting process, it is common to measure the load of the molten steel in the tundish. In this regard, reference may be made to Korean Patent Registration No. 10-0770337 (Oct. 19, 2007).

 However, it is difficult to measure the tundish load due to the heat radiated from the molten steel filled in the tundish. The heat released from the molten steel in the tundish can not only deform or damage the tundish, but also causes the load cell to malfunction due to its high temperature.

As described above, when the tundish moves due to the aligning operation of the hydraulic cylinder in the process of aligning the sen- sheses of the tundish, the load cell designed for the vertical load is subjected to the horizontal load, . This may lead to instability of the operation, and since the process can not be carried out while the lifetime of the load cell is being replaced, the productivity may be directly deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to make it possible to efficiently control the amount of molten steel by measuring a load of a tundish, for example.

It is also an object of the present invention to provide a measurement environment capable of preventing malfunction of the load cell by minimizing the horizontal load applied to the load cell due to movement of the tundish and extending the service life of the load cell.

Since the bolt is inserted into the hollow portion to perform the sliding motion in the left and right direction, it is preferable that the diameter of the hollow portion is larger than the diameter of the bolt.

At this time, an oilless bush may be inserted into the hollow portion of the bracket 111. This is to reduce the friction with the bolt sliding in the right and left directions in the hollow portion of the bracket.

The oilless bush is a dry lubricant bearing in which a special solid lubricant is embedded in a metal base material. The fine particles of the solid lubricant form a fine lubricating film on the sliding surface of the moving part during the friction exercise, .

Further, since the abrasion resistance is high, it is suitable for an environment of high load and reciprocating motion, so that it can be used without difficulty in the lower portion of the tundish 1 under high load.

The tundish 1 is linearly or rotationally moved to align the seno nozzle 4.

Accordingly, when the tundish 1 is moved, the load cell connected to the lower portion of another V-block receives a horizontal load. The apparatus load measuring apparatus 300 includes a tundish 1 moving by the conveying means, The load cell can be moved in the horizontal or vertical direction by a certain distance, so that the horizontal load applied to the load cell can be minimized, and damage or malfunction of the load cell can be prevented.

Therefore, the first and second hydraulic cylinders 5a and 5b for aligning the position of the seno nozzle 4 on the upper surface of the support body 3 and the first and second hydraulic cylinders 5a and 5b are moved together with the tundish by the driving of the first and second hydraulic cylinders. The tundish car including the equipment load measuring device 300 for measuring the load of the tundish enables effective control of the molten steel flow and the amount of molten steel.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be apparent to those of ordinary skill in the art.
