Abstract
The utility model relates to a guide device which is used to roll flat rolls, belongs to the rolled steel technical field, and is used to solve the problems that rolled pieces slide with guide boards and the rolled pieces are scraped since the rolled pieces are inclined in rolling the flat rolls. The guide device comprises a left guide board and a right guide board which are symmetrically arranged, wherein the left guide board and the right guide board are pass-through types after modification and guide rolls are arranged on an inlet and an outlet of the guide boards. The guide device designs two guide boards of an exiting flat roll rolling guide device into a pass-through type rolling guide board with the guide rolls, the rolled pieces can be closely contacted with the guide rolls through the modification, and the guide rolls and the rolled pieces generate rolling frication when the rolled pieces operate, which not only can not scrape the rolled pieces, but also can accurately right the rolled pieces. The guide device successfully solves the problem that the rolled pieces generate skew and steel inversion and in an exiting flat roll formation rolling technique and can be used in flat roll rolling steel billets and rough rolling passes of bar and wire rolling.
Description
Technical field
The utility model relates to a kind of steel rolling guide device, and used guide and guards when particularly adopting flat rolling with the rough rolling step of side, the rolling square steel of rectangular cross section continuous casting billet, bar, wire rod belongs to technical field of steel rolling.
Background technology
Flat rolling is a kind of new rolling technique, and it is meant adopts the plain-barreled roll of anapsid that rolled piece is carried out formation rolling.The flat rolling technology is remarkable in aspect effects such as reduction rolling cost, raising milling train efficient and reduction required powers.The problem that existing flat rolling technology mainly exists is that owing to adopt plain-barreled roll not have the sidewall restriction, rolled piece is easy to generate crooked i.e. " off-square " and even the steel that falls in the operation of rolling.If the off-square amount is big, then be difficult to continue rolling.For addressing the above problem, the guide and guards that prior art adopts in flat rolling is through guide plate, but because of having certain clearance between guide plate and rolled piece, can make rolled piece produce small inclination, and rolled piece also can produce sliding friction with guide plate, scratch rolled piece, even steel-fastening easily.Therefore, even if adopt through guide plate not can solve existing the problems referred to above in the flat rolling yet.
Summary of the invention
The utility model is used to overcome the defective of prior art and a kind of deflector roll that is provided with on guide plate is provided, thus make rolled piece stable, do not produce the crooked guide and guards that is used for flat rolling.
The alleged problem of the utility model is solved by following technical scheme:
A kind of guide and guards that is used for flat rolling comprises symmetrically arranged left and right guide plate in the formation, its special feature is: described left and right guide plate is through, is provided with deflector roll 2 at the inlet position and the outlet position of guide plate.
The above-mentioned guide and guards that is used for flat rolling, described left and right guide plate is package assembly, and it is formed by entrance guide plate 1-1 and delivery guide 1-2 butt joint, and joint is provided with the convex-concave chock 6 and the notch 7 of mutual coupling.
The above-mentioned guide and guards that is used for flat rolling is provided with rolling bearing between described deflector roll and guide plate.
The utility model improves at the problem that tilts because of rolled piece in the existing flat rolling and guide plate produces sliding friction, scratch rolled piece, two guide plates of its guide and guards are designed to have the through rolling guide of deflector roll, through this improvement, rolled piece can closely contact with deflector roll, deflector roll and rolled piece produce rolling friction during the rolled piece operation, neither rolled piece can be scratched, and rolled piece can be set upright accurately again.The utility model has successfully solved rolled piece in the existing plain-barreled roll formation rolling technology and has produced askew, as to fall steel problem, can be used for the roughing passage of flat rolling steel billet and rod, wire rod rolling.
Description of drawings
Fig. 1 is the utility model medial surface structural representation;
Fig. 2 is the utility model lateral surface structural representation;
Fig. 3 is that the A of Fig. 1 is to view.
Each parts label is as follows among the figure: 1. guide plate; 1-1. entrance guide plate; 1-2. delivery guide; 2. deflector roll; 3. roll; 4. gland; 5. bearing cap; 6. chock; 7. notch.
The specific embodiment
Referring to Fig. 1, the utility model comprises symmetrically arranged left and right guide plate 1 in constituting, and guide plate is through, and between two rolls 3, it runs through whole rolling deformation district, is provided with deflector roll 2 at the inlet position and the outlet position of guide plate.In the operation of rolling, rolled piece is set upright in deflector roll and rolled piece generation rolling friction accurately, and it is crooked that rolled piece is not produced.Left and right guide plate is package assembly, it is formed by entrance guide plate 1-1 and delivery guide 1-2 butt joint, joint is provided with the convex-concave chock 6 and the notch 7 of mutual coupling, and entrance guide plate and delivery guide join in the deformed area, and chock and notch that linking part is provided with convex-concave can guarantee that butt joint is stable, firm.
Figure 2 shows that the one side that the utility model lateral surface does not promptly contact with rolled piece.
Referring to Fig. 1～3, the rolling bearing (not shown) is set between deflector roll and guide plate, bearing adopts the circular cone roller bearing, and bearing is fixing with bearing cap 5, and the bearing end is provided with gland 4.
Claims (3)
