Description

Technical Field

[0001] The utility model belongs to the technical field of steel rolling production, and particularly relates to a diversion device for guiding the ice cones falling off under the eaves of a temper mill housing to the strip steel transportation working surface. Background Art

[0002] In the production process of cold-rolled stainless steel, tempering is an indispensable part. After annealing and pickling of cold-rolled stainless steel, a temper mill is required for tempering treatment. The temper mill is used to eliminate or reduce the shape defects, improve the surface quality of the strip steel, improve the surface roughness of the strip steel, eliminate the yield platform of the material, and improve the elongation of the material, which plays a very important role in ensuring the quality of the strip steel. However, due to the low temperature in winter, especially in China with a vast territory, the night temperature in most areas can reach below -4°C in winter. Due to the too low external temperature, the wet tempering water mist of the temper mill will condense into ice cones at the eaves of the housing at its inlet and outlet. And to ensure that the lubricating oil pipe of the temper mill roller can normally supply lubricating oil to the roller without being affected by the low temperature in winter, so as to ensure the normal rotation of the roller, hot steam is usually continuously blown through the corresponding pipeline to the oil pipe, so that the lubricating oil in the oil pipe will not freeze due to the low temperature. Therefore, some of the hot steam blown out by the corresponding pipeline will also condense into ice cones at the eaves of the housing at the inlet and outlet of the temper mill due to the low external temperature. After the temperature rises, the ice cones will fall off onto the strip steel surface. When the strip steel passes through the working rollers of the temper mill, the ice cones on it will not only damage the working rollers, but also cause periodic roller marks on the strip steel, thus affecting the tempering quality of the strip steel. In the prior art, it is necessary to replace the new working rollers to solve the problem of their damage, which increases the production cost of the strip steel. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a diversion device for the ice cones falling off under the eaves of a temper mill housing, so as to solve the technical problems that the ice cones condensed in winter on the existing temper mill will fall onto the strip steel surface and easily damage the working rollers, and affect the quality of the strip steel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a kind of ice cone deflector device of the skin pass mill of the present utility model with reference to the drawings.

[0021] As Figures 1-4As shown in the figure, the ice cone diversion device of the leveling machine of the present utility model includes a diversion groove 1. The diversion groove 1 is arranged below the eave 31 of the frame of the leveling machine 3. There is a fixed rod 2 above it. The diversion groove 1 is correspondingly connected to the eave 31 through the fixed rod 2. A flow diversion groove 4 is arranged on one side of the diversion groove 1. After the ice cone 33 condensed on the eave 31 of the frame falls off, it drops into the diversion groove 1. The diversion groove 1 guides the ice cone 33 out from below the eave 31 of the frame, so that it leaves the transportation working surface corresponding to the strip steel 32 on the leveling machine 3, thereby preventing the ice cone 33 from falling onto the strip steel 32 and preventing it from damaging the working roll 34 of the strip steel 32 machine. The ice cone 33 in the diversion groove 1 is introduced into the corresponding collection device 41 through the flow diversion groove 4 for subsequent treatment, preventing it from falling on the side of the transportation surface of the strip steel 32 on the leveling machine 3 due to improper treatment, thereby affecting the environment around the strip steel 32 and further affecting the work of the staff. For example, after the ice cone 33 randomly falls on the side of the strip steel 32, it is easy to form an ice layer on the ground, which is extremely likely to cause the staff to slip and cause danger. After centralized treatment, the occurrence of danger is avoided.

[0022] The diversion groove 1 includes two corresponding diversion plates 11, which are arranged obliquely relative to each other, and the bottom edges of the two are correspondingly connected. Among the two diversion plates 11, the one on the inner side of the leveling machine 3 is the inner plate 111, and the one on the outer side of the leveling machine 3 is the outer plate 112. Both the inner plate 111 and the outer plate 112 are inclined. Among them, the inner side edge of the inner plate 111 is higher than its outer side edge, and the outer side edge of the outer plate 112 is higher than its inner side edge. The outer side edge of the inner plate 111 and the inner side edge of the outer plate 112 are correspondingly connected. In this embodiment, the two diversion plates 11 are integrally formed and fixedly connected. The length of the diversion plate 11 is not shorter than the width of the strip steel 32. In this embodiment, the length of the diversion plate 11 is the same as the width of the leveling machine 3. The space above the corresponding inner sides of the two diversion plates 11 is the diversion cavity 12 of the diversion groove 1. The bottom surface of the diversion groove 1 where the two diversion plates 11 are connected is set as an arc with a large radius. The bottom surface of the large arc of the diversion cavity 12 is more likely to slide out along the diversion groove 1 when the ice cone 33 falls. At the same time, it can also prevent the ice cone 33 from condensing at the outer bottom end of the diversion groove 1 due to sharp corners, thereby causing the diversion device to fail.

[0023] The diversion direction of the diversion groove 1 is not parallel to the transportation surface of the strip steel 32. In this embodiment, the diversion direction of the diversion groove 1 is perpendicular to the advancing direction of the strip steel 32. The length of the diversion groove 1 is not shorter than the width of the strip steel 32. In this embodiment, the length of the diversion groove 1 corresponds to the width of the leveling machine 3. The diversion groove 1 is inclined. There is a certain angle between the bottom end of its diversion cavity 12 and the horizontal plane. In this embodiment, the bottom surface of the right end of the diversion groove 1 is higher than the bottom surface of its left end. The outlet of the diversion groove 1 is arranged at the low end on its left side. The ice cone 33 in the diversion cavity 12 leaves the diversion groove 1 through its outlet.

[0024] Inside the diversion channel 1, there is a fog baffle 13. The outer end of the fog baffle 13 is connected to the inner side edge of the diversion channel 1, and the two are fixedly and sealed. In this embodiment, the two are integrally formed. The inner side edge of the inner plate 111 extends towards the inside of the planishing mill 3 to form the fog baffle 13. The inner end of the fog baffle 13 gradually slopes downwards to the side above the work roll 34. Its width is not shorter than the width of the transportation surface of the strip steel 32. In this embodiment, the width of the fog baffle 13 corresponds to the width of the inner cavity of the planishing mill 3. The fog baffle 13 blocks the outside of the work roll 34 above the planishing mill 3, which can prevent the moisture inside the planishing mill 3 from spilling under the diversion channel 1 at the outer end of the planishing mill 3 and prevent the moisture from condensing into ice cones 33 under the diversion channel 1. At the same time, the fog baffle 13 can also introduce the excess moisture inside the planishing mill 3 into the diversion channel 1, so that it converges and condenses into water in the diversion channel 1, and then is discharged along the diversion channel 1, reducing the generation of ice cones 33.

[0025] At the upper end of the diversion channel 1, there is a connecting plate 14. The upper end of the connecting plate 14 fits the bottom surface of the housing eaves 31, and its lower end is connected to the upper end of the diversion plate 11. In this embodiment, the connecting plate 14 includes a front plate and a rear plate. The outer side edge of the outer plate 112 extends vertically upwards to form the front plate. The upper end of the front plate fits the bottom surface of the outer end of the housing eaves 31. The inner side edges on the left and right sides of the fog baffle 13 on the inner plate 111 extend vertically upwards to form the rear plate. The upper end of the rear plate fits the bottom surface of the inner end of the housing eaves 31. Since the diversion channel 1 is inclined, the height of the connecting plate 14 also changes with the inclination of the diversion channel 1. In this embodiment, the upper ends of the connecting plate 14 are all flush with the bottom surface of the housing eaves 31. The bottom surface of the connecting plate 14 gradually decreases from right to left with the inclination of the diversion channel 1.

[0026] Above the diversion channel 1, there are multiple fixing rods 2. The lower end of the fixing rod 2 is connected to the diversion channel 1, and the upper end of the fixing rod 2 is connected to the housing eaves 31. The two are detachably connected. In this embodiment, a pair of fixing rods 2 are provided on the inner and outer sides and the right side of the diversion channel 1 respectively. Each pair of fixing rods 2 corresponds to each other along the midline of the corresponding surface of the diversion channel 1 where it is located, so that the diversion channel 1 is more stable and not easy to fall off after installation. To prevent the diversion device from failing due to the formation of ice cones at the lower ends of the fixing rods 2 connected to the inner and outer sides of the diversion channel 1, the corresponding fixing rods 2 on the inner and outer sides of the diversion channel 1 are all arranged on the corresponding connecting plates 14 on the left and right sides of the transportation surface of the strip steel 32. There are no fixing rods 2 above the transportation surface of the strip steel 32. The upper end of the fixing rod 2 extends out from above the diversion channel 1, and a corresponding fastening device is provided at its top for the corresponding installation of the diversion device and the housing eaves 31 of the planishing mill 3.

[0027] The fastening device includes a fixed plate 21 and a movable plate 22 that cooperate with each other. A pair of fixed plates 21 that are parallel to each other up and down are arranged at the upper end of one side of the fixed rod 2 corresponding to the flow guide groove 1. The corresponding side edges of the two fixed plates 21 are connected to the fixed rod 2. The two fixed plates 21 include an upper plate 211 and a lower plate 212. Among them, the upper plate 211 is arranged at the top end of the fixed rod 2, and the upper plate 211 corresponds to the gap between the arch eaves 31 and the top plate of the planishing machine 3. To facilitate the corresponding installation of the lower plate 212, a through groove corresponding to the lower plate 212 is provided on the side wall corresponding to the flow guide groove 1, and the lower plate 212 passes through the through groove. A movable plate 22 is arranged between the two fixed plates 21. The movable plate 22 is connected to the lower plate 212 through a screw 23 at its lower end. A through hole 24 corresponding to the screw 23 is provided on the lower plate 212. The upper end of the screw 23 is fixedly connected to the lower surface of the movable plate 22, and the lower end of the screw 23 passes through the through hole 24, and they are slidably connected to each other, so that the movable plate 22 can move up and down between the two fixed plates 21. Two corresponding fastening nuts 25 are connected in series on the screw 23. The two fastening nuts 25 are respectively arranged on the screw 23 on the upper and lower sides of the lower plate 212. The screw 23 and the fastening nut 25 are connected through corresponding thread fits. The fastening nut 25 on the lower side of the lower plate 212 can prevent the screw 23 and the components above it from falling off the fixed rod 2. With the cooperation of the two fastening nuts 25, the distance between the movable plate 22 and the upper plate 211 can be adjusted through the fastening nut 25 on the upper side of the lower plate 212. During installation, the upper plate 211 is inserted into the gap between the arch eaves 31 and the top plate of the planishing machine 3, and the fastening nut 25 is rotated. The distance between the movable plate 22 and the upper plate 211 is adjusted through the screw 23, so that the lower end surface of the upper plate 211 is tightly attached to the upper end surface of the arch eaves 31, and the top surface of the movable plate 22 is tightly attached to the bottom surface of the arch eaves 31, so that the two are engaged on the upper and lower sides of the arch eaves, and then the flow guide groove 1 is installed below the arch eaves 31. In this way, it is convenient to install the flow guide device in winter. After winter, when the temperature rises and there are no icicles 33 on the arch, it is convenient to remove the flow guide device. The lengths of its left and right ends connected to the fixed rod 2 correspond to the outer side walls of the corresponding connected flow guide grooves 1.

[0028] Furthermore, a flow diversion groove 4 is arranged on the outer side wall of the planishing machine 3. In this embodiment, it is arranged on the outer side wall on the left side of the planishing machine 3. The upper end of the flow diversion groove 4 is provided with an ice inlet, and the lower end is provided with an ice outlet. The flow diversion groove 4 is correspondingly connected to the outlet of the flow guide groove 1 through its upper ice inlet. A corresponding collection device 41 is provided at its lower ice outlet. In this embodiment, an ice collection bucket is used for collection. The flow diversion groove 4 inputs the ice exported from the flow guide groove 1 into the ice collection bucket for subsequent processing.

[0029] In use, a diversion device is provided under the housing eaves 31 at the inlet and outlet of the temper mill 3. The two diversion devices can be arranged mirror-symmetrically along the center line of the temper mill 3. The flow-diverting grooves 4 of the two diversion devices are provided on the same outer side wall of the temper mill 3, and are arranged obliquely in opposite mirror symmetry. The ice outlets of the two flow-diverting grooves 4 correspond to the same ice collection bucket, so that the two diversion devices share the same ice collection bucket. The ice cones 33 condensed on the housing eaves 31 at both ends of the inlet and outlet of the temper mill 3 are introduced into the same ice collection bucket through the diversion devices, which saves more resources and makes the subsequent centralized treatment of the ice cones 33 more convenient.

[0030] After the installation of the ice cone diversion device of the utility model, it effectively prevents the influence of the ice cone 33 on the product quality of the strip steel 32, avoids the generation of periodic roll prints on the surface of the strip steel 32 caused by it. At the same time, it also avoids the damage of the ice cone 33 to the work roll 34 of the temper mill 3, improves the product quality of the strip steel 32 and the smoothness and safety of the operation of the temper mill 3 equipment, extends the service life of the temper mill 3, and increases its economic benefits.
