Description

Continuous casting machine sand-guiding device and control method thereof

Technical Field

The invention relates to the technical field of metallurgy, in particular to a continuous casting machine sand diversion device and a control method thereof.

Background

Currently, metallurgical enterprises, particularly steel enterprises, cast molten steel into billets using continuous casting processes. Molten steel in the ladle flows out through a sliding water gap at the bottom of the ladle, flows into a tundish through a tundish long water gap connected below the sliding water gap, is buried below the molten steel surface at the lower end of the long water gap, and flows out into a crystallizer through the tundish to form a casting blank.

When the ladle molten steel of the continuous casting machine is poured, the drainage sand filled in the ladle nozzle flows out firstly, and if no measures are taken, the drainage sand flowing out during each pouring can enter a continuous casting tundish to become impurities in the molten steel of the tundish. If the impurities in the molten steel in the intermediate tank can not float upwards in time and flow out from the overflow port, the impurities can enter the continuous casting steel billet to form large nonmetallic inclusions or surface slag inclusions in the steel billet, thereby reducing the quality of the continuous casting steel billet and severely restricting the production of high-quality steel types such as excellent steel and the like.

If the drainage sand is discharged outside the intermediate tank, the ladle slide plate is started before the ladle is transferred to the pouring position of the intermediate tank, and the ladle is transferred to the pouring position for pouring after the drainage sand is discharged. Thus, the preparation time is increased, the ladle self-opening rate is reduced, the secondary oxidization of molten steel is increased, and in addition, a certain danger exists for the personal safety of operators.

As shown in fig. 1, the prior art discloses a device for discharging casting ladle casting sand, which comprises a ladle 1, a long nozzle 2, a sand receiving tank 3 and a tundish 4, and the action process is as follows: and opening a ladle slide plate by aligning the sand receiving groove 3 with the lower opening of the long water gap 2, leading the drainage sand to fall into the sand receiving ladle 3, discharging the drainage sand out of the intermediate tank 4, removing the sand receiving groove 3 before molten steel is dropped, and lowering the ladle 1 for production. The above-described sand drainage device has the following disadvantages.

The method has the following defects: in order to ensure that the drainage sand can be smoothly discharged out of the intermediate tank 4, the sand receiving ladle 3 must have enough inclination, which requires enough space between the long water gap 2 and the intermediate tank 4, but the actual space is only 200-300 mm in the field, which can not meet the implementation requirement of the device.

And the second disadvantage is that: the sand drainage device is difficult to implement, has the problem of how to remove the sand receiving ladle 3, and has high labor intensity and high risk coefficient if manually removed.

As shown in fig. 2, the prior art also discloses a ladle drainage sand separation device and a tundish, which comprises a sand collecting tank 11 and a sand guiding cap 13, wherein the sand collecting tank 11 is provided with a molten steel channel 12 and a sand containing cavity 1. The sand guiding cap 13 of the device is positioned below the ladle long nozzle, and a middle tank is positioned below the device. When the drainage sand guides molten steel to come out of the ladle long nozzle, the drainage sand enters the sand containing cavity 1 of the sand collecting groove 11 through the sand guiding cap 13, and when the molten steel comes out, the drainage sand can burn through the sand guiding cap 13 and enter the intermediate tank through a molten steel channel of the sand collecting groove 11. The above device has the following disadvantages.

The method has the following defects: the sand guiding cap 13 needs to be replaced every time the device is used, and the use is very inconvenient.

And the second disadvantage is that: the sand containing cavity 1 of the sand collecting groove 11 is replaced by new sand after being filled with the drainage sand, and the use is very inconvenient.

And the third disadvantage is: the device also has the problems of large volume and no installation space.

For this reason, there is a need for a continuous casting machine sand-guiding device and a control method thereof, which solve at least one of the above problems.
