[0016] The utility model discloses a strip steel coiler side guide plate with replaceable wear-resistant lining plate, as shown in the figure, Figures 1-5 Including the base lining plate 1, the inside surface of base lining plate 1 is installed with the detachable wear-resistant lining plate 2, the wear-resistant lining plate 2 is provided with a plurality of tapered grooves 3, and the hard alloy 4 is arranged in each tapered groove 3. The setting of hard alloy 4 can improve the hardness of wear-resistant lining plate 2, and as the part in contact with the strip steel, can effectively improve the service life of wear-resistant lining plate 2.

[0017] The lower position of the inside surface of base lining plate 1 is provided with the installation groove 5 matched with wear-resistant lining plate 2, the first countersunk hole 6 is formed in the upper side of base lining plate 1 of installation groove 5, the second countersunk hole 7 is formed in the base lining plate 1 at the position of installation groove 5, and the through hole 8 is formed in wear-resistant lining plate 2 corresponding to the position of second countersunk hole 7. The first countersunk hole 6 and the second countersunk hole 7 are fixed on the rack of rolling mill by bolts, the setting of through hole 8 does not affect the installation of bolts in the second countersunk hole 7, compared with the traditional integral side guide plate, the original installation hole is retained, and the installation adaptability with rolling mill is improved. The first countersunk hole 6 and the second countersunk hole 7 are all sunken in the inside of base lining plate 1, and the head of the bolt in the inside will not be affected by the wear of wear-resistant lining plate 2.

[0018] In order to realize the stable installation between the base lining plate 1 and the wear-resistant lining plate 2, a plurality of third countersunk holes 9 are arranged on the outer side of the base lining plate 1, the wear-resistant lining plate 2 is provided with threaded holes 10 corresponding to the third countersunk holes 9, and the corresponding threaded holes 10 and the third countersunk holes 9 are matched and installed with connecting bolts 11. The threaded holes 10 penetrate the entire thickness of the wear-resistant lining plate 2, the connecting bolts 11 are adaptively installed with the threaded holes 10, and the heads of the connecting bolts 11 are located on the outer side of the base lining plate 1. Even if the wear-resistant lining plate 2 and part of the connecting bolts 11 are worn, the connecting performance of the wear-resistant lining plate 2 and the base lining plate 1 can be guaranteed.

[0019] After the installation of the wear-resistant lining plate 2, the end of the hard alloy 4 is limited by the contact of the installation groove 5, and at the same time, the hard alloy 4 cannot be separated from the wear-resistant lining plate 2 due to the shape limitation of the tapered groove 3.

[0020] When the strip head first contacts the side guide plate, if the thickness direction of the feeding end of the side guide plate is arranged at a right angle with the inner side guide surface, the strip head will be subjected to a great blocking force after colliding with the thickness position of the side guide plate, and even the strip will be stuck. In order to avoid the above situation, the feeding end of the base lining plate 1 is provided with a first arc surface 12, and the feeding end of the wear-resistant lining plate 2 is provided with a second arc surface 13 corresponding to the first arc surface 12. The arrangement of the first arc surface 12 and the second arc surface 13 can guide the strip head to the inner contact surface of the side guide plate more smoothly, thereby effectively reducing the direct collision damage and prolonging the service life.

[0021] Further, the slope of the tapered groove 3 is 1-3 degrees, the hard alloy 4 is a circular truncated cone matched with the tapered groove 3, and the end surface with smaller diameter of the hard alloy 4 is flush with the inner side surface of the wear-resistant lining plate 2. When the hard alloy 4 and the wear-resistant lining plate 2 are simultaneously subjected to contact wear by the rolling steel, due to the difference in hardness, the base of the wear-resistant lining plate 2 will be worn first, and the rolling steel will contact the relatively sharp part between the upper end surface and the side surface of the hard alloy 4 during the guiding and conveying process, and scratches will be generated on the side surface of the strip. In order to solve the above problem, as shown in Figure 6 , the dashed line in the figure represents the end position of the strip, and a third arc surface 14 arranged in a circle is further arranged between the end surface with smaller diameter of the hard alloy 4 and the side surface. The arrangement of the third arc surface 14 eliminates the relatively sharp part of the outer periphery of the hard alloy 4. After the base of the wear-resistant lining plate 2 is worn, the strip contacts the third arc surface 14 and can be guided smoothly to the end surface of the hard alloy 4, thereby reducing the scratches and defects on the side surface of the strip and making the quality of the side surface of the strip more excellent.

[0022] Further, as shown in Figure 7As shown, the upper and lower sides of the wear-resistant lining plate 2 are provided with the plug-in plates 15, and the mounting groove 5 is provided with the plug-in grooves 16 matched with the plug-in plates 15. The arrangement of the plug-in plates 15 and the plug-in grooves 16 ensures the stability and reliability of the wear-resistant lining plate 2 after installation, which helps to maintain the constant pressure control of the side guide plate during the process of coiling the steel strip, avoids the single-end warping of the wear-resistant lining plate 2 under the extrusion, and improves the guiding accuracy and stability of the steel strip.

[0023] Further, the wear-resistant lining plate 2 is provided with two types of hard alloy 4 with different diameters, and the hard alloys 4 with different diameters are arranged at intervals. The above design enables the side guide plate to adapt to the coiling requirements of the steel strip with different specifications and materials, and improves the flexibility and adaptability of the equipment.

[0024] Further, the lower side of the wear-resistant lining plate 2 is arranged at an angle of 1-5 degrees relative to the bottom of the base lining plate 1. The above structure enables the arrangement of the wear-resistant lining plate 2 to be more consistent with the guiding and conveying of the steel strip, and also improves the installation adaptability and stability between the wear-resistant lining plate 2 and the base lining plate 1.

[0025] When the steel strip enters between the two side guide plates, the wear-resistant lining plate 2 will continue to be impacted and rubbed. The connecting bolts 11 are prone to breakage under the continuous impact, which causes the wear-resistant lining plate 2 to separate from the base lining plate 1. To solve the above problem, as shown in Figure 10 As shown, the mounting groove 5 is provided with a plurality of limiting grooves 17, and the side surface of the wear-resistant lining plate 2 is provided with the limiting blocks 18 matched with the limiting grooves 17. The two sides of the limiting block 18 are provided with inclined surfaces 19. When the wear-resistant lining plate 2 is impacted, the force can be transmitted to the connecting bolts 11 and the limiting blocks 18, thereby effectively increasing the connecting strength between the wear-resistant lining plate 2 and the base lining plate 1, reducing the deformation or breakage of the connecting bolts 11 under the impact force. Meanwhile, the arrangement of the inclined surfaces 19 on the two sides of the limiting block 18 enables the wear-resistant lining plate 2 to be installed more conveniently, without the need to align the limiting blocks 18 with the limiting grooves 17. The subsequent tightening of the connecting bolts 11 and the guiding of the inclined surfaces 19 can realize the cooperative installation of the wear-resistant lining plate 2 and the base lining plate 1, and improve the connecting strength between the wear-resistant lining plate 2 and the base lining plate 1.

[0026] The base lining plate 1 can be made of a general plate material or a manganese plate material, and the mounting position for embedding the hard alloy material is processed. Then, the hard alloy is embedded on the wear-resistant lining plate 2, and the base lining plate 1 is connected with the wear-resistant lining plate 2 by bolts to be used as a whole, and the base lining plate 1 retains the original mounting hole.

[0027] After the hard alloy 4 is added, the service life of the side guide plate is 5-10 times of that of the traditional mode and material. In the case that the base lining plate 1 is not damaged, the replaceable wear-resistant lining plate 2 can be disassembled and replaced with a new wear-resistant lining plate 2 after the wear-resistant lining plate 2 inlaid with the hard alloy 4 is worn, so that the purpose of replacing only the wear-resistant part of the lining plate is achieved, the base lining plate 1 is reused, a large amount of use cost is saved, and the replacement cycle is shortened.

[0028] The cost of the processed base lining plate 1 is about 9000 yuan / ton, accounting for about 80% of the total weight, and the cost of the replaceable wear-resistant lining plate 2 inlaid with the hard alloy 4 is about 80 yuan / kg, accounting for about 20% of the total weight. One base body can be matched with at least five alloy inlaid plates, and compared with the original five integral lining plates, the comprehensive ton price is lower than 18000 / ton, the cost of the user is greatly saved, a lot of maintenance cost is saved, and the production efficiency is improved.

[0029] The replaceable wear-resistant lining plate of the strip steel coiler side guide plate has the advantages of optimizing the structure design, improving the wear resistance, being convenient to maintain and replace, effectively solving the problems in the prior art, improving the service life and production efficiency of the strip steel coiler, reducing the use cost and maintenance difficulty, and having remarkable economic and social benefits.
