They enable the rolled piece to accurately enter and exit the die according to the specified position, direction and required state, avoiding the rolled piece from getting tangled in the rolls, being scraped or squeezed, and ensuring the safety of workers and equipment.

[0003] Currently, most profile production lines use integrated guide devices. To ensure the guides can withstand the cyclic impacts of the rolled pieces, these integrated guide devices are often quite heavy. Furthermore, the integrated design means that each guide can only be used for one type of profile. For the production of multiple profiles, this results in a large inventory of various guide types, increasing the cost of spare parts. With the development of production and technological advancements, mill guides in profile production lines, especially mill exit guides, are increasingly evolving towards better controllable rolling posture, easy adjustment, lightweight design, high reliability, versatility, and additional functionalities.

[0004] The improvement direction of the outlet guide of the section steel finishing mill under this development trend is to adopt a modular split structure. The split structure can realize the sharing of spare parts for various types of profiles, which can save spare parts costs. The split structure has the advantages of lightweight structure and high reliability of guide steel. It can also be equipped with a cooling function for the side wall of the rolling groove. In addition, it can be designed with impact-resistant flexible matching characteristics for the working conditions of large section of profile rolling, high inertia and periodic impact, which is safe and reliable.

A middle pad 6 is located below the lower guard plate 5, and lining plates 7 are located on both sides of the middle pad 6. Fastening screws 8 laterally connect the lower parts of the left and right box-side guide plates 3 and 16 to the middle pad 6 and lining plates 7 to form a box body. The upper end of the upper guard plate 4 is engaged with a slot on the lower surface of the guide beam 1 of the frame via a locking block, with a gap of 5-10mm. The lower surface of the lower guard plate 5 is connected to the upper surfaces of the box-side guide plates 3, the middle pad 6, and the lining plates 7 via a locking block. Cooling water pipes 25 are located on the outer sides of the two box-side guide plates 3. The head of the outlet guide is the entry end of the rolled piece, and the tail is the exit end of the rolled piece. The lower surface of the head of the lower guard plate 5 is in close contact with the surface of the lower groove of the rolling mill. The lifting ring 12 above the center of gravity of the upper guard plate is connected to the crossbeam of the guide beam 1 by the lifting rod 10 and is suspended by the counterweight of the hammer head 11 to ensure that the upper surface of the head of the upper guard plate 4 is in close contact with the surface of the upper groove of the rolling mill.

[0019] Figure 3 The display shows that the lower surface of the guide beam 1 of the frame has a guide beam slot 2, which is a right-angled trapezoidal slot. The upper surface of the upper guard plate 4 has an upper locking block 13, which is also a right-angled trapezoid. The upper locking block 13 matches the guide beam slot 2 and is embedded in the guide beam slot 2, connecting the upper guard plate 4 to the guide beam 1. To ensure that the upper guard plate can move slightly forward, backward, up, and down, Figure 2 The cover plate of the middle guide beam slot 2 has a certain gap.

[0020] Figure 1 , 4 The display shows that there is a suspension rod 10 above the upper guard plate 4.

The outer ends of the support plates 24 are tightly connected to the inner walls of the two box side guide plates 3, ensuring that the upper retaining plate 4 and lower retaining plate 5 are centrally connected to the box side guide plates 3. The spacing between the retaining plates 4 and lower retaining plates 5 in the height direction is 10-15mm higher than the die height during assembly to ensure the passage of the rolled piece.

[0023] The width of the upper guard plate 4 and the lower guard plate 5 shall not exceed 60% of the width of the roll pass. The outer shape of the guide surfaces of the upper guard plate 4 and the lower guard plate 5 shall be consistent with the roll pass of the mill stand. The contact arc length between the guard plate and the roll shall not be less than 40mm. The horizontal projection distance from the bottom of the groove to the guard plate plane and from the guard plate plane to the front end of the guard plate shall be 10~15mm to improve the fit and bearing capacity with the workpiece and ensure good guidance of the guard plate to the workpiece, allowing it to enter and exit the roll pass in an ideal state. The maximum thickness of the upper guard plate 4 shall be less than 100mm, and the maximum thickness of the lower guard plate 5 shall be less than 80mm. Weight reduction holes shall be designed at the tail of the guard plates.

Multiple round holes 20 on both sides of the intermediate pad 6 correspond to the connecting through holes 18 on the base 15 of the box side guide plate 3. Fastening screws 8 pass through the round holes 20 to connect the intermediate pad 6 to the base 15 of the box side guide plate 3. The upper surface of the intermediate pad 6 has a pad groove 21 at the front. The pad groove 21 is perpendicular to the length direction of the intermediate pad 6 and is connected to the box groove 19 of the box side guide plate 3.
