Technical Field

The utility model relates to a steel rolling metallurgy field, in particular to steel rolling trough device.

Background

The hollow steel wire continuous rolling unit is generally connected in series by adopting a plurality of continuous rolling mills, and 2 groups of water penetrating tanks are adopted after finish rolling for cooling control after rolling. Because the distance between the frames of the continuous rolling unit is 4-6 meters, and the middle of the continuous rolling unit is also provided with the loop device, the continuous rolling system adopts the heating rolling, and the means of cooling or temperature control rolling in the steel rolling process cannot be realized. However, for producing steel products with special requirements, such as deformed steel bar, 20CrMnTi, 60Si2CrV and other steel grades, temperature control rolling is needed to meet the performance requirements of the steel products.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a steel rolling trough device that wears plays the purpose that reduces the rolling steel temperature, refines the steel crystalline grain, satisfies the material performance requirement.

According to the utility model discloses an aspect provides a steel rolling trough device, including bottom plate, first curb plate, second curb plate, the both sides that first curb plate and second curb plate are fixed in the bottom plate respectively form the cell body, the inboard of first curb plate is equipped with first wash pipe, the inboard of second curb plate is equipped with the second wash pipe, first wash pipe and second wash pipe all are the slope setting.

In some embodiments, the two first flushing pipes are symmetrically arranged, and the water outlet ends of the first flushing pipes are inclined downwards towards the middle of the tank body.

In some embodiments, the two second flushing pipes are symmetrically arranged, and the water outlet ends of the second flushing pipes are inclined downwards towards the middle of the tank body.

In some embodiments, one end of the first side plate is provided with a first feeding guide plate, one end of the second side plate is provided with a second feeding guide plate, and the first feeding guide plate and the second feeding guide plate are arranged oppositely.

In some embodiments, the first and second feed guide plates extend laterally in a trumpet shape.

The utility model has the advantages that: the steel plate is adopted to manufacture the trough body which can be rolled by steel, the side plates of the trough body are provided with the opposite flushing pipes, and the natural water pool is formed by the flushing pipes spraying water and oppositely flushing. In the rolling process, the water in the water tank is submerged in the steel, so that the whole steel can be completely cooled. The utility model discloses a basin device is worn in steel rolling is used in a plurality of rolling mill exports, plays the rolling purpose of segmentation cooling to rolling in-process steel, reaches the effect that refines steel crystalline grain, satisfies the mechanical properties requirement of steel.

Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

Fig. 1 to 3 schematically show a rolled steel water passing tank device according to an embodiment of the present invention.

Referring to fig. 1 to 3, a steel rolling flume device includes a bottom plate 1, a first side plate 2, a second side plate 3, a first flush pipe 4, a second flush pipe 5, a first feeding guide plate 6, and a second feeding guide plate 7. The first side plate 2 and the second side plate 3 are respectively fixed on two sides of the bottom plate 1 to form a groove body, two ends of the groove body are in a through shape, and steel rolling can pass through the groove body. The inboard of first curb plate 2 is equipped with first wash pipe 4, and the inboard of second curb plate 3 is equipped with second wash pipe 5, and first wash pipe 4 and second wash pipe 5 all are the slope setting.

The two first flushing pipes 4 are symmetrically arranged and are respectively positioned at two ends of the first side plate 2, and one water outlet end of each first flushing pipe 4 inclines downwards towards the middle of the tank body.

The two second flushing pipes 5 are symmetrically arranged and are respectively positioned at two ends of the second side plate 3, and one water outlet end of each second flushing pipe 5 inclines downwards towards the middle of the tank body.

One end of the first side plate 2 is provided with a first feeding guide plate 6, one end of the second side plate 3 is provided with a second feeding guide plate 7, and the first feeding guide plate 6 and the second feeding guide plate 7 are arranged oppositely. The first feeding guide plate 6 and the second feeding guide plate 7 extend laterally to form a horn shape, and the first feeding guide plate 6 and the second feeding guide plate 7 are positioned at one end of a steel rolling feed inlet of the device and play a role in guiding steel rolling conveying.

When the device is used, a special pipeline is paved to be connected with the first flushing pipe 4 and the second flushing pipe 5, production water is introduced, and the water pressure is ensured to be more than or equal to 3 kg. And the rolled steel passes through the groove body after coming out of the outlet of the continuous rolling mill, and is sprayed with water through a water pipe to carry out bidirectional hedging so as to form a flowing natural water pool. Through the export setting at a plurality of tandem mills the utility model discloses a basin device is worn in steel rolling plays the rolling purpose of segmentation cooling to rolling in-process steel, reaches the effect of refining steel crystalline grain, satisfies the mechanical properties requirement of steel.

Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating the technical solution of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
