Description

Technical Field

[0001] This utility model belongs to the technical field of steel rolling equipment, and particularly relates to a bridge device and rolling equipment for steel rolling production. Background Technology

[0002] In the steel rolling process, the cleanliness of the rolling channel has a crucial impact on the quality of the steel, the performance of the rolling mill, and the production efficiency.

[0003] With the increasing demands for steel quality from modern industry, the requirements for cleaning rolling channels are also becoming more stringent. In traditional steel rolling production, a large amount of impurities such as iron oxide scale, oil, and debris remain in the rolling channels. If these impurities are not removed in time, they will be pressed into the surface of the steel during the rolling process, forming surface defects such as pits, dents, and scratches, seriously affecting the surface quality of the steel, reducing its product grade and market competitiveness. On the other hand, the accumulation of impurities will also accelerate the wear of equipment such as rolls, shorten the service life of the equipment, increase equipment maintenance costs and downtime, and thus affect production efficiency.

[0004] In existing technologies, the main method for cleaning rolling mill channels is manual cleaning. Manual cleaning typically involves workers using high-pressure water guns to clean the rolling mill channels. This method is not only labor-intensive, but the cleaning effect is also greatly affected by the worker's skill level and work attitude. Furthermore, there are certain safety risks involved in the cleaning process. Therefore, how to design a technology that reduces labor intensity, ensures consistent cleaning, and improves operational safety is the technical problem this utility model aims to solve.

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0025] In one respect, combination Figures 1 to 5 As shown in the figure, this disclosure provides a bridge device for steel rolling production. The bridge device for steel rolling production includes a base 1, a receiving component 2, two side plates 3, a cover plate 4, and a water spraying assembly 5.

[0026] The receiving component 2 has a plate-like structure and is fixedly installed on the upper end of the base 1.

[0027] Combination Figure 3 As shown, two side plates 3 are arranged opposite to each other and fixedly mounted on the receiving part 2. The two side plates 3 and the receiving part 2 together define the bridge passage 31 for the transition between rolling processes. During the rolling process, the intermediate billet of the steel needs to pass through multiple rolling mills. Each rolling mill is responsible for performing specific deformation and processing on the intermediate billet. The bridge passage 31 is mainly used for the intermediate billet to pass through.

[0028] The cover plate 4 is placed on the upper end of the two side plates 3, and the cover plate 4 has a first mounting hole.

[0029] The water spray assembly 5 is fixed to the cover plate 4, passes through the first mounting hole and extends into the bridge passage 31. The water spray assembly 5 is configured to spray water toward the upper surface of the receiving member 2.

[0030] Specifically, the bridge device for steel rolling production includes a base 1, a receiving component 2, two side plates 3, a cover plate 4, and a nozzle 51 assembly. The two side plates 3 and the receiving component 2 together define the bridge passage 31. The cover plate 4 is located at the upper end of the two side plates 3. Water is sprayed onto the receiving component 2 in the bridge passage 31 through the first mounting hole on the cover plate 4 via the water spraying assembly 5. This reduces the intensity of manual labor. At the same time, the water spraying and cleaning of the bridge passage 31 by the nozzle 51 assembly can ensure the consistency and thoroughness of the cleaning, eliminating the need for manual cleaning and improving operational safety.

[0031] In some embodiments of this application, combined with Figure 2 As shown, the water spray assembly 5 includes a nozzle 51, a fixing plate 52, and a water supply component 53.

[0032] The nozzle 51 passes through the first mounting hole, and the water spraying end of the nozzle 51 extends into the bridge channel 31. The nozzle 51 is used to spray water toward the upper surface of the receiving part 2. During installation, the nozzle 51 is located at the upper end of the bridge channel 31, avoiding the moving area of ​​the intermediate blank.

[0033] The fixing plate 52 has a plate-like structure and is located above the cover plate 4. The fixing plate 52 is connected to the outer edge of the nozzle 51 around the periphery.

[0034] Specifically, the fixing plate 52 is fixed to the cover plate 4 by fasteners, thereby fixing the nozzle 51 to the cover plate 4.

[0035] Water supply component 53 is connected to nozzle 51 and is configured to supply water to nozzle 51.

[0036] For example, the water supply component 53 includes a water pump, the water inlet of which is connected to a water source through a first pipe, and the water outlet of which is connected to a nozzle 51 through a second pipe.

[0037] In some embodiments of this application, a second mounting hole is formed on the cover plate 4, and the steel rolling production bridge device also includes an electrical control module and a thermal detection probe 6.

[0038] The thermal detection probe 6 passes through the second mounting hole and is fixed on the cover plate 4. The detection end of the thermal detection probe 6 extends into the bridge passage 31.

[0039] The thermal detection probe 6 and the water supply component 53 are both electrically connected to the electrical control module. The thermal detection probe 6 is used to detect the temperature inside the bridge passage 31. The electrical control module receives the temperature and controls the water supply component 53 to work when the temperature is lower than the set temperature threshold.

[0040] Understandably, the temperature threshold can be set based on the temperature of the intermediate billet.

[0041] In some embodiments of this application, combined with Figure 4 As shown, the thermal detection probe 6 is closer to the inlet end of the bridge channel 31 than the nozzle 51.

[0042] Specifically, by positioning the thermal detection probe 6 closer to the inlet end of the bridge channel 31 than the nozzle 51, the thermal detection probe 6 can detect the temperature in a timely manner and transmit the temperature signal to the control module, which then controls whether the water supply component 53 is working.

[0043] In some embodiments of this application, combined with Figure 5 As shown, the nozzle 51 is arranged at a downward angle along the direction from the inlet end of the bridge passage 31 to the outlet end of the bridge passage 31.

[0044] In this way, if the direction of the intermediate billet movement is taken as forward, the nozzle 51 sprays water forward and downward, so that the bridge passage 31 can be sprayed with water in a comprehensive manner.

[0045] In some embodiments of this application, the receiving member 2 includes a first plate segment 21 and a second plate segment 22 connected to each other. The first plate segment 21 is located at the open end of the bridge passage 31 and is inclined downward. The second plate segment 22 is arranged horizontally, and the nozzle 51 sprays water toward the connection between the first plate segment 21 and the second plate segment 22.

[0046] Specifically, the second plate segment 22 is arranged horizontally. When the nozzle 51 sprays water towards the connection between the first plate segment 21 and the second plate segment 22, it can spray water all over the second plate segment 22 along the direction of the intermediate billet's advance, sweeping away the debris on the second plate segment 22. Since the first plate segment 21 is inclined downward, some water will flow to the first plate segment 21, thereby carrying away the debris on the first plate segment 21, thus achieving thorough cleaning.

[0047] In some embodiments of this application, the tilt angle of the nozzle 51 is α, where 30°≤α≤60°.

[0048] Specifically, the nozzle 51 is tilted at 30°~60° to spray water, and the water flow has a component speed in both the forward and downward directions, which can drive the debris forward and move it out of the bridge passage, and can also impact stubborn stains; ensuring that the water flow can be concentrated on the surface of the receiving part 2, thereby more thoroughly removing the debris accumulated on the surface of the receiving part 2.

[0049] For example, the tilt angle α of the nozzle 51 is 30°, 35°, 40°, 45°, 50°, 55° or 60°.

[0050] In some embodiments of this application, the opening end of the bridge passage 31 is flared.

[0051] Specifically, the opening end of the bridge passage 31 is funnel-shaped with a large opening, which facilitates the smooth entry of the intermediate billet into the bridge passage 31 and avoids accidents such as the intermediate billet warping out.

[0052] In some embodiments of this application, the bridge device for steel rolling production also includes ear plates 7.

[0053] The ear plate 7 is located on the outside of the bridge passage 31 and is fixedly connected to the side plate 3 and the receiving part 2 respectively. The ear plate 7 has a lifting hole 71.

[0054] Specifically, by setting ear plates 7, which have lifting holes 71, the safety and efficiency of lifting are improved, and the installation of the bridge device for steel rolling production is facilitated.

[0055] For example, the working process is as follows: When the intermediate billet enters the bridge channel 31, the thermal detection probe 6 detects the intermediate billet by detecting its temperature. The thermal detection probe 6 transmits a signal to the control module, which then controls the water supply component 53 to stop supplying water to the nozzle 51. When the intermediate billet is removed from the bridge channel 31, the thermal detection probe 6 detects the temperature and transmits a signal to the control module, which then controls the water supply component 53 to supply water to the nozzle 51. The nozzle 51 sprays water towards the connection between the first plate segment 21 and the second plate segment 22, sweeping away debris on the second plate segment 22. As the water flows downward along the first plate segment 21, it carries away debris from the first plate segment 21, thereby achieving a thorough cleaning of the bridge channel 31.

[0056] The steel rolling production bridge device of this application can automatically flush the bridge channel 31, with a high degree of automation, ensuring the consistency and thoroughness of cleaning. It can effectively flush narrow spaces and hard-to-reach areas, avoiding long-term accumulation of impurities, which helps to ensure the surface quality of intermediate billets and reduces the labor intensity and safety risks for workers.

[0057] In a second aspect, the present invention provides a rolling mill, which includes a rolling mill, an installation platform 8, and a bridge device for steel rolling production according to any one of the embodiments in the first aspect.

[0058] The mounting platform 8 is located between two adjacent rolling mills, and its bottom is fixed.

[0059] The steel rolling production bridge device is detachably installed on the installation platform 8; wherein, the inlet end of the bridge channel 31 is opposite to the outlet end of one rolling mill, and the outlet end of the bridge channel 31 is opposite to the inlet end of another rolling mill.

[0060] Since it includes any of the steel rolling production bridge devices in the first aspect embodiment, it has all of its beneficial effects, which will not be elaborated here.

[0061] In some embodiments of this application, the base 1 is provided in four sets, and the four sets of base 1 are located at the four corners of the bottom of the receiving member 2. Each set of base 1 includes a support plate 11 and a positioning post 12.

[0062] The upper end of the support plate 11 is connected to the receiving part 2. The positioning post 12 has a cylindrical structure and is vertically set on the support plate 11. The plane of the support plate 11 is parallel to the forward direction of the intermediate blank. The top of the mounting platform 8 is provided with two mounting plates 81 opposite each other. The four support plates 11 are stuck between the two mounting plates 81. A positioning groove 811 is formed on each mounting plate 81 at the position corresponding to the positioning post 12.
