Description

Descaling ring guide plate shared by round billet and square billet

Technical Field

The utility model belongs to the technical field of the steel rolling, especially, relate to a descaling ring baffle of circle base, square billet sharing.

Background

During the rolling of steel, scale on the surface of the billet needs to be removed by the descaling rings, i.e. descaling, and during the descaling, the billet is conveyed to the descaling rings through the conveying rollers and is guided to pass through the descaling rings through guide plates on both sides of the conveying rollers. Because the steel billet adopted by the prior rolling line is of a single specification, the opening degrees of the left guide plate and the right guide plate of the descaling ring do not need to be changed. With the change of billet supply, the billets adopted in the existing rolling line are not of a single variety, namely: in order to adapt to the situation, the rolling lines in China currently adopt a mechanical adjustment mode to change the opening degrees of the left guide plate and the right guide plate so as to meet the requirement of guiding steel billets of different sizes and shapes. However, the adjustable descaling ring guide plate has the following defects: one is prone to failure. The environment around the descaling ring is severe, the descaling ring is high in temperature and large in water vapor, and after the mechanical adjusting device is used for a period of time, the descaling ring is easy to deform and corrode, and the descaling ring is stuck. Secondly, the operation is complicated. When a steel billet with one specification is changed, the opening degrees of the left guide plate and the right guide plate of the descaling ring need to be adjusted, so that the labor and the time are wasted, and the efficiency is low.

SUMMERY OF THE UTILITY MODEL

In order to solve the existing problem, the utility model provides a descaling ring baffle of circle base, square billet sharing, this descaling ring baffle need not to adjust the structure, can pass through the descaling ring with the different steel billet guide of variation in size, shape, has reduced equipment cost, has improved work efficiency, has ensured safety in production.

In order to achieve the above object, the present invention adopts the following technical solutions, including:

the left guide plate is connected to the left side of the rollgang rack, and the right guide plate is connected to the right side of the rollgang rack; the left guide plate and the right guide plate are fixed and immovable; the left guide plate and the right guide plate can contain round billets or square billets of different sizes and guide the round billets or the square billets to pass through the phosphorus removal ring, and both the left guide plate and the right guide plate extend longitudinally.

Furthermore, the left guide plate and the right guide plate are both single-shaped guide plates.

Furthermore, the left guide plate is a left single guide plate, the right guide plate is a right single guide plate, a small-diameter round billet or a large-diameter square billet can be accommodated between the left single guide plate and the right single guide plate, the range is considered, and the square billet width K-100mm < the diameter D of the round billet is less than or equal to the width K of the square billet.

Furthermore, the left guide plate and the right guide plate are both composite guide plates.

Furthermore, the left guide plate comprises a left inner guide plate and a left outer guide plate, the right guide plate comprises a right inner guide plate and a right outer guide plate, a large-diameter round billet or a small-diameter square billet can be accommodated between the left outer guide plate and the right outer guide plate, the range is considered, and the diameter D of the round billet is larger than the width K of the square billet and larger than the diameter D-100mm of the round billet.

Furthermore, the height H of the left single guide plate and the right single guide plate is D/2+20 mm-50 mm; the distance S between the left single guide plate and the right single guide plate is K +80 mm-100 mm.

Further, the height H1 of the left outer guide plate and the right outer guide plate is D/2+ 20-50 mm; the height H2 of the left inner guide plate and the right inner guide plate is 100 mm; the width B2 of the left inner guide plate and the right inner guide plate is 70 mm-100 mm; the distance S between the left inner guide plate and the right inner guide plate is [ D ]²-(D-H2)²]^1/2/2+50mm～100mm。

The utility model relates to a descaling ring baffle of circle base, square billet sharing, this descaling ring baffle need not to adjust the structure, can pass through the descaling ring with the different steel billet guide of variation in size, shape, has reduced equipment cost, has improved work efficiency, has ensured safety in production.
