Description

Technical Field

[0001] This utility model relates to the technical field of cooling control equipment, and in particular to a flow distribution mechanism and a separate cooling control device for each line. Background Technology

[0002] In the current controlled cooling system of multi-line slitting (two-line, three-line, four-line) rolling mill, the controlled cooling nozzles generally have structural design defects. Specifically, the water supply channels of each group of controlled cooling nozzles are interconnected, and no independent separation and control unit is set up, which makes it impossible to individually control the cooling temperature of a single slitting line. In actual production, when the cooling temperature of a single slitting line needs to be adjusted, if heating is required, the machine must be stopped and some nozzles of the corresponding slitting line replaced with empty tubes; if cooling is required, the machine must be stopped and the number of nozzles of the corresponding slitting line increased. The above adjustment method has the following technical drawbacks: each temperature adjustment requires one crane operator and two ground workers to work together, and each adjustment takes 15 minutes, with frequent shutdowns severely disrupting the production cycle; during the shutdown adjustment period, the heating furnace needs to be kept warm, consuming additional gas resources; after replacing nozzles or empty tubes, the cooling conditions of each slitting line are difficult to match completely, requiring multiple shutdowns and repeated adjustments, still unable to guarantee temperature uniformity; frequent shutdowns increase the workload of operators and also increase the hidden costs of equipment maintenance; excessive temperature fluctuations in each slitting line directly affect the metallographic structure and mechanical properties of the bars, resulting in poor consistency in the performance of the finished product.

[0027] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0028] Example 1 Reference Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides a flow-diverting mechanism to achieve precise diversion of cooling medium to multiple sets of slit-line controlled cooling positions, while ensuring structural stability and ease of installation and calibration. It includes a base 1, which has two sets of slit-line components spaced laterally; a mounting beam 2, which connects to the upper side of the two sets of base 1, and the mounting beam 2 includes two sets of longitudinal beams 21 and two sets of transverse beams 22; and a flow-diverting component 3, which is disposed between the transverse beams 22 and the base 1, and cooperates with one of the longitudinal beams 21 to divert the cooling medium to the controlled cooling position of the corresponding slit line.

[0029] The two sets of bases 1 are spaced apart along the tangent line, and their upper surfaces have welding bevels adapted to the longitudinal beams 21 to enhance the connection strength with the longitudinal beams 21. The mounting beam 2 includes two sets of longitudinal beams 21 and two sets of transverse beams 22. The longitudinal beams 21 are spaced apart along the cooling medium conveying direction, and their lower ends are welded to the upper surfaces of the two sets of bases 1 by submerged arc welding. The transverse beams 22 are spaced apart along the transverse direction, and their two ends are welded to the upper ends of the two sets of longitudinal beams 21 by argon arc welding. The mounting beam 2 as a whole forms a "double U-shape", with the lower part enclosed by the two sets of longitudinal beams 21 and the two sets of bases 1, and the upper part enclosed by the two sets of longitudinal beams 21 and the two sets of transverse beams 22, to avoid deformation caused by long-term impact of the cooling medium.

[0030] Furthermore, the diversion component 3 includes four sets of square tubes 31, a guide hole 34, a conveying pipe 35, and a 90-degree elbow; Four sets of square tubes 31 are arranged in a rectangular array between the front base 1 and the front crossbeam 22. Circular holes 32 are opened on the upper and lower surfaces of the square tubes 31. The cooling nozzle 33 is fixed to the preset hole position of the crossbeam 22, and the inlet end of the cooling nozzle 33 is aligned with the upper round hole 32 of the square tube 31. The two are sealed by a high-temperature resistant silicone sealing ring to ensure that the cooling medium does not leak. The guide holes 34 are located in the middle of the right longitudinal beam 21 and run through the thickness of the longitudinal beam 21. There are four sets in total, and they correspond one-to-one with the round holes 32 of the square tube 31. The two ends of the conveying pipe 35 are sealed to the guide holes 34 and the round holes 32 by clamps respectively. Among them, the first set of conveying pipes 35 is connected in a straight line. The other three sets of conveying pipes 35 are turned and connected by stainless steel 90-degree elbows to avoid flow loss caused by bending of the hose.

[0031] The calibration base 4 is rectangular in shape and is fixed between two sets of longitudinal beams 21 by bolts. Four rectangular grooves 41 are provided on the upper surface of the calibration base 4, and the longitudinal center line of the rectangular grooves 41 corresponds one-to-one with the center line of the four sets of square tubes 31, which are used to calibrate the position of the cutting line and the cooling nozzle 33 during installation.

[0032] In use, the cooling medium enters through the guide hole 34 of the right longitudinal beam 21; the medium flows into the corresponding square tube 31 through four sets of conveying pipes 35; the medium in the square tube 31 enters the cooling nozzle 33 on the crossbeam 22 through the round holes 32 on the upper and lower surfaces; the cooling nozzle 33 sprays the cooling medium in a direction to the corresponding cutting line cooling position, realizing multi-line synchronous flow splitting; During installation or maintenance, the dicing line is positioned by the rectangular groove 41 of the calibration seat 4 to ensure the alignment accuracy of the cooling nozzle 33 with the dicing line and avoid cooling offset.

[0033] Example 2 Reference Figure 5This is the second embodiment of the present invention. Unlike the previous embodiment, an adjustment control 5 is added to the diversion mechanism of embodiment 1 to achieve independent control of the cooling medium flow rate of each group of split lines. The adjustment control 5 includes a diversion tank 51, a water supply pipe 52, and four sets of water inlet pipes 53. One end of the water supply pipe 52 is connected to the water inlet of the diversion tank 51, and one end of each of the four sets of water inlet pipes 53 is connected to the diversion tank 51, and the other end is connected to the four quick connectors of the diversion mechanism.

[0034] The distribution tank 51 has a cylindrical structure. One end of the water supply pipe 52 is connected to the inlet of the distribution tank 51 through a flange, and the other end is connected to an external cooling medium source. The water supply pipe 52 is equipped with a shut-off valve to control the total medium supply. There are four sets of water inlet pipes 53. One end is connected to the distribution tank 51 through a quick connector. The outlet of the distribution tank 51 is evenly distributed along the circumference of the tank body, with a spacing of 30° and set in pairs. The other end is connected to the four quick connectors of the distribution mechanism one by one. The regulating valve 54 is a manual ball valve. Each group of water inlet pipes 53 is connected in series with a regulating valve 54. The regulating valve 54 is installed close to the diversion tank 51, which makes it easy for the operator to adjust the flow rate. The valve body is equipped with a scale for precise control of the opening degree.

[0035] During use, the shut-off valve of the water supply pipe 52 is opened, and the external cooling medium enters the distribution tank 51; Based on the cooling requirements of the four split lines, such as line 1 requiring strong cooling and line 2 requiring weak cooling, adjust the regulating valve 54 on the corresponding inlet pipe 53: The regulating valve for line 1 is opened from level 54 to level 8, with a flow rate of approximately 8 m³ / h. The regulating valve for line 2 is opened to level 3, with a flow rate of approximately 3 m³ / h. Lines 3 and 4 will be adjusted to the corresponding speeds based on demand; The adjusted cooling medium enters the guide hole 34 of the diversion mechanism through the water inlet pipe 53. The subsequent process is the same as in Example 1. Finally, it is precisely sprayed onto the corresponding cutting line through the cooling control nozzle 33 to achieve independent cooling control of the cutting line.

[0036] By adjusting the opening degree of the regulating valve 54 in each pipeline, the water inlet volume of the corresponding water beam can be precisely controlled, thereby achieving independent fine-tuning of the cooling temperature of each cutting line, meeting the temperature control requirements of rolling bars of different specifications, without the need to stop the machine to replace nozzles or empty pipes.
