Description

Technical Field

[0001] This utility model relates to the field of continuous casting machine technology, and in particular to a hot billet delivery line for continuous casting machines. Background Technology

[0002] In the current production process of billet continuous casting machines in China, the cut billets are conveyed through multiple channels of the conveying track during the feeding process. The billets are then flipped onto the diversion track by the billet flipping machine. The billet transfer car then performs the billet pushing action, pushing multiple billets to the feeding area of ​​the flipping cooling bed or the waiting area of ​​the hot conveying roller table. The billets are then sent to the rolling mill for rolling operations via the hot conveying roller table waiting area.

[0003] In the existing structure, multiple conveying rollers are arranged side by side on the conveying track, and multiple guide sleeves are set on the conveying rollers along the axial direction, forming a multi-channel conveying track along the conveying direction. However, since the conveying cross-sectional width of the multiple guide sleeves is constant, when the conveying cross-sectional width of the guide sleeves and the reserved gaps on both sides of the billet are large, the billet is prone to tilting at both ends along the conveying track, resulting in different turning radii at both ends of the billet, which easily causes the billet to collide or fall. When the conveying cross-sectional width of the guide sleeves and the reserved gaps on both sides of the billet are small, it is easy to cause jamming at the discharge port of the fire cutting machine, which seriously affects the conveying efficiency of the hot conveying line.

[0019] Furthermore, the variable diameter channel, the limiting diameter channel, and the guide channel are all centered.

[0020] Furthermore, the conveying roller is provided with an installation groove corresponding to the position of the guide sleeve;

[0021] Furthermore, the guide sleeve includes a symmetrical first semicircular arc segment and a second semicircular arc segment, and extends to form a fixed flange at the joint of the first semicircular arc segment and the second semicircular arc segment.

[0022] Furthermore, the conveying roller has a hollow cavity inside, and multiple partitions are provided in the hollow cavity along the axial direction. The outer edges of the partitions have gaps, and a through pipe is provided along the center line to connect multiple partitions in series.

[0023] An air supply device is provided at the drive end of the conveyor roller. The air supply device is connected to the through pipe through an air inlet pipe, and an annular gap is formed between the air inlet pipe and the conveyor roller.

[0039] like Figures 1 to 8 The hot conveying line for the continuous casting machine shown includes: a support frame, and a first hot conveying roller conveyor 1 and a second hot conveying roller conveyor 2 arranged in a cross shape on the support frame; the second hot conveying roller conveyor 2 is located at the end of the conveying of the first hot conveying roller conveyor 1 and is located above the first hot conveying roller conveyor 1; the first hot conveying roller conveyor 1 includes a plurality of conveying rollers 111 arranged side by side, and a plurality of guide sleeves 112 are installed on the conveying rollers 111; a linkage mechanism 3 is provided at the intersection of the first hot conveying roller conveyor 1 and the second hot conveying roller conveyor 2, and the linkage mechanism 3 is used to flip and transfer the steel billet on the first hot conveying roller conveyor 1 to the second hot conveying roller conveyor 2;

[0040] The first hot conveying roller conveyor 1 includes a correction section 11 and a reversing section 12 along the conveying direction. The reversing section 12 is located directly below the second hot conveying roller conveyor 2. The guide channel width of the guide sleeve 112 of the correction section 11 is greater than the guide channel width of the guide sleeve 112 of the reversing section 12. A correction section 13 is provided at the conveying end of the correction section 11. The correction section 13 is provided with a first correction component 131, a support roller 132 and a second correction component 133 in sequence along the conveying direction of the first hot conveying roller conveyor 1.

[0041] The first correction component 131 includes multiple variable diameter channels 131a corresponding to the multi-channel, and the second correction component 133 includes multiple limited diameter channels 133a corresponding to the multi-channel. The variable diameter channels 131a gradually shrink along the conveying direction, and the width of the limited diameter channels 133a is equal to the guide channel width of the guide sleeve 112 of the flipping section 12.

[0042] The first hot conveying roller conveyor 1 is divided into a correction section 11 and a turning section 12, and a correction section 13 is set at the end of the conveying process. This helps to correct the billet before it enters the turning section 12, reducing tilting. The variable diameter channel 131a and the limiting diameter channel 133a can be set to gradually adjust the billet, reducing the risk of impact or falling due to inaccurate positioning. This ensures that the billet enters the guide channel of the guide sleeve 112 in the turning section 12 smoothly, avoiding jamming and improving the conveying efficiency of the hot conveying line.

[0043] In the preferred embodiment of this utility model, the first correction component 131 includes two symmetrically arranged limiting plates; a variable diameter channel 131a is formed between the opposite surfaces of the two limiting plates, and the two ends of the variable diameter channel 131a gradually converge inward from the ends toward the middle position, which can ensure the centering of the steel billet in the variable diameter channel 131a, reduce the offset, and by utilizing the guiding and positioning function of the limiting plates, the occurrence rate of steel billet jamming or failure can be reduced, the continuous operation capability of the production line can be improved, and the design of the limiting plates allows for adjustment of steel billets of different widths, which improves the applicability of the correction component.

[0044] As a preferred embodiment of the above embodiment, the variable diameter channel 131a is provided with an equal-width channel 131b at the middle position. The open structure at both ends of the equal-width channel 131b provides a smooth transition for the steel billet when entering and leaving the variable diameter channel 131a, reducing the impact and wear caused by the diameter change. The design of the equal-width channel 131b helps to reduce stress concentration of the steel billet when passing through the variable diameter channel 131a, avoiding deformation or damage of the steel billet due to stress concentration.

[0045] In a preferred embodiment, the support roller 132 is provided with a transition sleeve 1321 corresponding to the diameter change channel 131a. The guide channel width of the transition sleeve 1321 is located between the guide channel width of the guide sleeve 112 of the correction section 11 and the width of the diameter limiting channel 133a. When the billet passes through the diameter change channel 131a to the transition sleeve 1321, the guide channel of the transition sleeve 1321 further fine-tunes the centering of the billet, avoiding damage to the billet caused by the sudden narrowing of the channel.

[0046] In this invention, the second correction assembly 133 includes multiple swing arms 1331 and a drive cylinder 1332 for driving the swing arms 1331 to swing. Two calibration blocks 1333 are provided on each swing arm 1331, and the two calibration blocks 1333 have corresponding guide channels with diameter-limiting channels 133a for the steel billet to pass through. The design of multiple swing arms 1331 and drive cylinder 1332 allows the correction assembly to be dynamically adjusted, while the diameter-limiting channels 133a formed by the calibration blocks 1333 can reduce direct contact between the steel billet and the correction assembly, reducing the risk of wear and damage.

[0047] In the preferred embodiment of this utility model, a transition roller 134 is also provided at the end of the correction section 13 to ensure a smooth transition of the billet from the correction section 13 to the flipping section 12, and to make the guide channel width of the guide sleeve 112 on the transition roller 134 equal to the guide channel width of the guide sleeve 112 on the flipping section 12, which helps the billet to maintain correct alignment before entering the flipping section 12 and improves the correction effect.

[0048] To ensure that each channel remains centered, reduce friction and wear against the channel walls, and improve conveying efficiency, the variable diameter channel 131a, the limiting diameter channel 133a, and the guide channel are all centered.

[0049] In this invention, the conveyor roller 111 is provided with a mounting groove corresponding to the guide sleeve 112; and the guide sleeve 112 includes a symmetrical first semicircular arc segment and a second semicircular arc segment, with a fixing flange extending from the joint of the first and second semicircular arc segments. The design of the mounting groove enables the guide sleeve 112 to be accurately positioned and fixed on the conveyor roller 111, ensuring the stability and reliability of the structure.

[0050] In a preferred embodiment of this utility model, the conveyor roller 111 has a hollow cavity inside, and multiple partitions 113 are provided in the hollow cavity along the axial direction. The outer edges of the partitions 113 have gaps, and a through pipe 114 is provided along the center line to connect multiple partitions 113 in series. An air supply device is provided at the driving end of the conveyor roller 111. The air supply device is connected to the through pipe 114 through an air inlet pipe, and an annular gap is formed between the air inlet pipe and the conveyor roller 111.

[0051] Uniform cooling of the roller is achieved by incorporating a through-pipe 114 and multiple baffles 113 within the hollow cavity. Cooling gas supplied to the hollow cavity by the air supply device flows along the axis of the through-pipe 114 until its end, then flows back to the inlet end through the gaps at the outer edges of the baffles 113, and finally exits from the annular gap. This precisely controlled gas flow path effectively avoids turbulence and ensures uniform cooling of the entire roller, which is crucial for extending roller life and improving operational safety, especially when operating in high-temperature environments.

[0052] In a preferred embodiment of this invention, the linkage mechanism 3 includes a swing arm 1331 and a driving member that supports and drives the swing arm 1331 to swing upwards. The driving member drives the swing arm 1331 to swing upwards, thereby transferring the steel billet from the first hot conveyor roller 1 to the second hot conveyor roller 2. Through the cooperation of the swing arm 1331 and the driving member, the linkage mechanism 3 can precisely control the transfer of the steel billet, ensuring that the steel billet is accurately transferred from the first hot conveyor roller 1 to the second hot conveyor roller 2. The structure of the second hot conveyor roller 2 is prior art and will not be described in detail here.

[0053] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
