Description

Technical Field

[0001] This invention relates to the field of side guide plate technology, and in particular to a processing technology for side guide plates in a high-temperature alloy hot rolling production line. Background Technology

[0002] Side guide plates, also known as guide plates, are important components on hot rolling production lines. They are used to ensure the stability and directionality of hot-rolled strip during its movement, especially before coiling, where there is usually one or more sets of side guide plates.

[0003] Chinese patent CN206415445U discloses a ceramic composite winding machine side guide plate, including a side guide plate body, a ceramic block, and bolts. The side guide plate body has slots with bolt holes at the bottom. The ceramic block is fixedly installed in the slots, and its surface is flush with the side guide plate body. The side guide plate body has two slots, with the central axis of each slot 40-60 mm from the nearest edge of the side guide plate body. The ceramic block is fixedly embedded in the slots by bolts. This utility model uses a ceramic composite winding machine side guide plate with the above structure. By embedding ceramic blocks in the easily worn parts of the side guide plate body, the high hardness, high wear resistance, high temperature resistance, corrosion resistance, and chemical stability of the ceramic blocks can significantly improve the performance and service life of the winding machine side guide plate.

[0004] The aforementioned patents and prior art have the following problems: However, the existing ceramics have poor toughness. When the hot-rolled strip enters the roller position, it will impact the ceramic side guide plate, causing the ceramic to break and wear the hot-rolled strip. When the ceramic surface is opened and fixed to the surface of the side guide plate by bolts, the bolts collide with the ceramic, causing the ceramic to break and aggravating the wear with the hot-rolled strip.

[0027] Preferably, the surfaces of the upper and lower convex plates 205 of the back plate 202 are provided with guide posts 2052.

[0028] Preferably, the back of the composite plate 204 is provided with a plurality of extension rods 2042, and a planar section 2041 is provided between adjacent extension rods 2042. A slot 2051 for accommodating the extension rods 2042 is provided between the pressure plate 203 and the convex plate 205 and between adjacent convex plates 205. The front end of the protruding plate 205 and the surface of the pressure plate 203 are both covered with a pad 207. The flat section 2041 corresponds to the pressure plate 203 at the front end of the protruding plate 205. The composite plate 204 is preferably a zirconia-toughened alumina ceramic or a ceramic with added silicon carbide. The pad 207 is preferably a high-temperature resistant rubber layer.

[0029] Preferably, the extension rod 2042 is threadedly connected to the back of the slot 2051 with a pull rod 206. The pull rod 206 passes through the back plate 202 and is threadedly connected to the reinforcement member 2021.

The pad 207 is preferably a heat-resistant rubber plate. The reinforcement member 2021 is preferably a nut.

[0030] Preferably, the side of the connecting plate 201 is provided with a plurality of composite plates 204, and the surfaces of adjacent composite plates 204 are respectively provided with inserts 2044 and grooves 2043, the inserts 2044 and grooves 2043 are engaged, and through holes are opened in the middle of the grooves 2043 and inserts 2044. An insert shaft 2045 is installed inside the through hole, and a nut is installed on the part of the insert shaft 2045 located on the outside of the composite plate 204.

[0031] The lower pressure roller 1044, conveyor roller 102, convex plate 205, as well as the stop arm 103 and sliding roller 1031 are all made of high-temperature resistant alloy. Operation process: By placing the connecting plate 201 on the top surface of the side of the conveyor frame 101 and installing the connecting plate 201 on the top surface of the conveyor frame 101 with bolts, when the hot-rolled strip is initially wound by the winding machine or held and moved on the top of the transport roller 102 by the clamp, or when the tail of the hot-rolled strip enters the transport roller 102, if a deviation occurs at this time, it will first collide with the stop arms 103 at intervals on both sides, causing the stop arms 103 to squeeze the buffer member 1051 inside the buffer arc cavity 105 through the arc rod 1052, thereby relieving the impact of the hot-rolled steel strip just entering the top surface of the transport roller 102, and when the hot-rolled strip continues to... When the hot-rolled strip moves on the surface of the transport roller 102, the symmetrical stop arm 103 and the sliding roller 1031 at the top of the transport roller 102, together with the buffer member 1051 connected by the arc rod 1052, can buffer the impact of the hot-rolled strip as it enters the top surface of the transport roller 102 and limit the deviation of the hot-rolled strip. This prevents the hot-rolled strip from excessively impacting the composite plate 204 after entering the surface of the transport roller 102. Furthermore, the stop arm 103 reduces the subsequent larger vibration deviation caused by the deviation vibration of the hot-rolled strip as it enters the surface of the transport roller 102, thereby preventing the subsequent excessive deviation of the hot-rolled strip from impacting the composite plate 204.

[0032] It should be noted that, for hot-rolled strips with a relatively high thickness that are pushed one by one onto the surface of the transport roller 102 for clamping and pulling, the elastic support of the second buffer member 1051 on the side of the stop arm 103 can be strengthened, so that the gap between the symmetrical stop arms 103 is smaller than the width of the hot-rolled strip. It is also smaller than the width between the symmetrical composite plates 204, so that the impact of the hot-rolled strips being pushed one by one onto the surface of the transport roller 102 is buffered by the two stop arms 103 in conjunction with the second buffer member 1051. For thinner hot-rolled strips, the gap between the symmetrical stop arms 103 will be larger than the width of the hot-rolled strip. However, this gap is smaller than the width between the symmetrical composite plates 204. When the hot-rolled strip is rolled and pulled, if there is a deviation vibration, it will hit the surface of the symmetrical stop arms 103 and be buffered and relieved by the buffer member 1051.

[0033] When the front end of the hot-rolled strip passes through both sides of the stop arm 103, the sliding roller 1031 located inside the stop arm 103 is in sliding contact with the hot-rolled strip. That is, when the hot-rolled strip shifts, it will slide into contact with the sliding roller 1031, reducing excessive impact wear on the stop arm 103 and the sliding roller 1031. Then, the downward pressure drive source 1041 is activated, causing the downward pressure drive source 1041 to drive the mounting frame 1043 and the downward pressure roller 1044 to move downward, so that the downward pressure roller 1044 presses against the surface of the stop arm 103, with a certain gap between them. This, together with the buffer 1042, buffers and prevents excessive jumping of the hot-rolled strip during movement. The offset impact on the composite plate 204 causes impact damage to the composite plate 204. Therefore, the symmetrical stop arm 103 and sliding roller 1031 restrict the lateral vibration impact of the hot-rolled strip, and the lower pressure roller 1044 and buffer 1042 restrict the longitudinal vibration of the hot-rolled strip, thereby reducing the offset impact force of the hot-rolled strip in the initial stage and during movement, and thus avoiding excessive impact of the hot-rolled strip on the composite plate 204, which would cause damage. Of course, the length of the lower pressure roller 1044 can also be made smaller than the gap between the symmetrical stop arms 103, so that the lower pressure roller 1044 and the surface of the hot-rolled strip can make sliding contact, further restricting the movement and jumping of the hot-rolled strip.

[0034] After passing through the lower pressure roller 1044, the hot-rolled strip moves on the surface of the transport roller 102. If the hot-rolled strip deviates at this time, it will come into contact with the composite plate 204. The composite plate 204 is preferably zirconia toughened alumina ceramic or silicon carbide-added ceramic, which makes the composite plate 204 have better wear resistance, heat resistance and impact resistance than ordinary ceramics. This avoids the need to stop the production line due to frequent replacement of the composite plate 204. As a ceramic substrate, the composite plate 204 has better wear resistance than metal materials, thus solving the problem of easy wear of metal side guide plates in the prior art.

[0035] The composite plate 204 is inserted into the slot 2051 between adjacent protruding plates 205 and between protruding plates 205 and pressure plates 203 via its extension rod 2042. A pad 207 is provided between the protruding plates 205 and pressure plates 203 and the flat section 2041 on the back of the composite plate 204, and a space is provided between the pad 207 and the composite plate 204 to avoid excessive contact between the composite plate 204 and the protruding plates 205. The high-temperature resistant rubber pad 207, which is wrapped around the outside of the protruding plates 205, can buffer the composite plate 204 when it is squeezed and comes into contact with the protruding plates 205, thereby further improving the buffering capacity of the composite plate 204. The upper and lower surfaces of the protruding plates 205 and the extension rod 2042 are also connected. A pad 207 is provided between 42, and the gap between the pad 207 and the extension rod 2042 is clamped by flexible metal or graphite, so that the extension rod 2042 is embedded in the inside of the slot 2051, reducing the accidental slippage of the extension rod 2042. The pressure plate 203 is clamped to the surface of the extension rod 2042 at the upper and lower ends of the composite plate 204 by the pad 207 and flexible metal or graphite, and is locked by the guide post 2052 on the surface of the upper and lower convex plate 205 with the nut, thereby clamping the upper and lower ends of the composite plate 204. After the extension rod 2042 is inserted into the inside of the slot 2051, it is locked by a long bolt passing through the back plate 202 and the reinforcement 2021 on the back of the extension rod 2042. The composite plate 204 is pulled and fixed by the pull rod 206 via the extension rod 2042. The surface of the extension rod 2042 inside the slot 2051 is held in place by the elastic rubber pad 207 and flexible metal or graphite, and is further fixed by the upper and lower clamping of the pressure plate 203. Therefore, even if the pull rod 206 and the single extension rod 2042 break due to vibration, the composite plate 204 as a whole will not separate from the protruding plate 205. Moreover, the connection between the pull rod 206 and the extension rod 2042 is on the back of the composite plate 204, thus avoiding the need for drilling holes in the ceramic plate surface and then using bolts as in the prior art. The bolts are fixed to the surface of the plate, so that when the ceramic plate is impacted, the bolt holes and bolts will be damaged by impact, causing the broken ceramic pieces to aggravate the wear of the hot-rolled strip. However, after the bolts of this invention fail, there is still the locking of the slot 2051 and the extension rod 2042, as well as the clamping and fixing of the pressure plate 203, so that the composite plate 204 as a whole will not separate from the convex plate 205. Moreover, the broken pieces between the pull rod 206 and the extension rod 2042 will only fall into the inside of the slot 2051, so that the hot-rolled strip will not come into contact with the vulnerable position of the composite plate 204, thereby aggravating the wear of the hot-rolled strip.

[0036] The buffer element 2061, positioned between the extension rod 2042 and the back plate 202, buffers the impact on the composite plate 204. The composite plate 204 transmits the impact force to the buffer element 2061 via the extension rod 2042, achieving lateral buffering. A pad 207 is positioned between the extension rod 2042 and the protruding plate 205, thus achieving longitudinal buffering. This prevents impact damage to the composite plate 204 caused by the hot-rolled strip impacting it, compensating for the insufficient toughness of the ceramic substrate of the composite plate 204. Combined with the zirconia-toughened alumina ceramic material of the composite plate 204, the composite plate 204 can better withstand the offset impact during the transfer of the hot-rolled strip.

[0037] The adjacent composite plates 204 are flexibly hinged together by grooves 2043 and inserts 2044, thus avoiding continuous chipping and breakage caused by the breakage of a whole piece or strip of ceramic. This makes the composite plates 204 more independent, ensuring that the breakage of any one composite plate 204 will not lead to the destruction of the entire structure. It also facilitates the removal of the insert shaft 2045, disconnecting the grooves 2043 and inserts 2044 to replace the individual composite plates 204. The adjacent composite plates 204 are locked together by the grooves 2043 and inserts 2044. Therefore, when a single composite plate 204 or multiple composite plates 204 are impacted, the impact will be transmitted to the surrounding composite plates 204 through the grooves 2043 and inserts 2044. This avoids the impact of a single composite plate 204's dent or bulge on the transported hot-rolled strip, ensuring the coordinated movement of the entire plane and the rapid return of the composite plates 204 to their original position. It should be noted that the surface of the insert shaft 2045 is also covered with a high-temperature resistant rubber layer for cushioning.

[0038] In summary: By replacing traditional metal materials with composite plate 204, high temperature resistance, wear resistance, and high toughness are achieved. Furthermore, through the cooperation of extension rod 2042 and slot 2051, the wear of composite plate 204 and pull rod 206 is limited to the back of composite plate 204. The pad 207 and buffer 2061 can buffer the longitudinal and transverse impact of the hot-rolled strip, reducing the breakage rate of composite plate 204. The damage of individual composite plates 204 will not affect the entire ceramic piece, making replacement easier. The linkage of multiple composite plates 204 is achieved through the cooperation of groove 2043 and insert 2044, ensuring that the overall plane will not have excessive protrusions that affect the movement of the hot-rolled strip.
