Abstract
Description
Technical Field
[0001] This application relates to the field of steel rolling equipment maintenance technology, and in particular to a method and related equipment for reducing residual emulsion in roll bearing housings. Background Technology
[0002] Currently, cold rolling mills generally employ automated procedures to complete roll replacement operations, including standardized steps such as stopping the machine, removing the old roll, inserting the new roll, and restarting the machine. During this process, the emulsion system shuts down upon receiving a stop command, and any residual emulsion in the pipeline is slowly discharged through nozzles. The roll bearing housing, as a critical load-bearing component, typically comprises three parts: the roll body, the roll neck, and the roll head. The bearing housing has a high surface roughness, right-angled edges on its upper surface, deep mechanical maintenance holes, and a surface roughness consistent with that of the traveling slide rail.
[0003] However, during the automatic roll removal process, the emulsion adhering to the surface of the old roll is directly carried out of the frame, resulting in unrecoverable liquid loss; the bearing housing has a high surface roughness and right-angled edges, making it easy for the emulsion to remain due to surface tension and difficult to slide off naturally by gravity; the mechanical maintenance holes have complex shapes and large depths, and the emulsion remaining in the holes is lost as the roll is removed during roll replacement; the traveling slider track, as the lowest point of the plane, has the same surface roughness as the bearing housing, causing the emulsion flowing down from above to be retained and carried out again, thereby increasing production costs. Summary of the Invention

[0023] Based on the second preset angle, the edge of the traveling slider track on the roller bearing seat is chamfered, and the coverage length of the copper slider on the traveling slider track is extended to match the plane of the traveling slider track.
[0024] In one embodiment of the present invention, the step of extending the coverage length of the copper slider on the walking slider track to match the plane of the walking slider track includes:

It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

The term "two or more" includes two or more cases.
[0040] Please see Figure 1 This is a schematic flowchart of a method for reducing residual emulsion in a roll bearing housing, provided by an embodiment of this application. Specifically, it may include:
[0041] S110. Obtain the mill roll changing instruction, and perform a preset number of segmented roll removal operations based on the mill roll changing instruction to obtain the roll removal optimization result;
[0042] For example, when the system receives a roll change command from the mill, it begins a segmented roll removal operation. During this process, the old roll is not removed all at once, but rather in segments according to a preset number of operations to achieve optimized removal, allowing the emulsion adhering to the roll surface to diffuse into the mill stand. This segmented roll removal operation enables the emulsion adhering to the old roll surface to fall into the mill stand due to increased liquid fluidity, effectively reducing the amount of emulsion carried out by the roll, minimizing waste, and thus reducing production costs. Simultaneously, through reasonable segmentation and set rest times, emulsion residue can be minimized without affecting roll change efficiency.
[0043] S120. Based on the optimization results of the roller drawing, the upper surface of the roller bearing housing is surface treated to obtain the surface treatment result;
[0044] For example, after completing the segmented roll pulling operation and obtaining the roll pulling optimization results, the upper surface of the roll bearing housing is surface-treated to obtain the surface treatment result. The surface treatment consists of four steps: first, surface cleaning; then, rough polishing and fine polishing; and finally, anti-oxidation treatment. This reduces the surface roughness of the upper surface, thereby increasing the fluidity of the liquid, reducing the adhesion of emulsion to the upper surface of the bearing housing, and thus reducing the amount of emulsion residue. Anti-oxidation treatment and periodic maintenance can delay surface rusting, maintain the stability of surface roughness, extend the service life of the bearing housing, and also ensure that the emulsion can continue to flow smoothly, further reducing emulsion residue.
[0045] S130. Based on the surface treatment result, the edges and corners of the upper plane are chamfered to obtain the chamfering result;
[0046] For example, after the surface treatment of the upper surface is completed, the edges and corners of the upper surface are chamfered. Specifically, the edges and corners of the upper surface are ground to obtain the chamfered result. This chamfering process increases the liquid diffusion capacity of the bearing housing frame, allowing the emulsion to flow out more smoothly from the edges, reducing emulsion accumulation at the edges, and further reducing the amount of residual emulsion. At the same time, it does not compromise the stability of the bearing housing, ensuring the normal operation of the equipment during high-speed rolling and avoiding problems such as vibration caused by changes in the frame structure.
[0047] S140. Based on the chamfering result, the mechanical maintenance hole on the roll bearing housing is sealed to obtain the sealing result;
[0048] For example, after chamfering the edges of the upper surface, a customized model is used to seal the mechanical maintenance holes according to their dimensions, resulting in a sealing effect. Sealing the mechanical maintenance holes can improve the amount of emulsion remaining in the bearing housing after the roller is pulled, reduce emulsion leakage or residue from these holes, thereby reducing emulsion loss, improving emulsion utilization, and lowering production costs.
[0049] S150. Based on the sealing results, a guide structure is set on the edge area of the traveling slider track on the roll bearing housing to shorten the residence time of the emulsion in the track area and guide it to be discharged.
[0050] For example, after sealing the mechanical maintenance holes, a guide structure is installed on the edge area of the traveling slider track on the roll bearing housing based on the sealing results. This shortens the residence time of the emulsion in the track area and guides its discharge. This increases the guiding force for emulsion discharge from the track area, shortens the residence time of the emulsion in the track area, allows the emulsion to be discharged more quickly, reduces the amount of emulsion residue at the track, improves the cleanliness and operating efficiency of the equipment, reduces corrosion and damage caused by emulsion residue, and extends the service life of the equipment.
[0051] In summary, the method for reducing emulsion residue in roll bearing housings proposed in this application effectively reduces the amount of emulsion adhering to the surface of the roll bearing housing and within the mechanical maintenance holes through segmented roll pulling operation, surface roughness optimization, and chamfering treatment, thereby reducing liquid carry-out losses during roll changing. Reduced emulsion waste directly lowers production costs, and the cost reduction effect is positively correlated with roll changing frequency, making it suitable for cold continuous rolling production lines with high-frequency roll changing.
[0052] In some examples, the step of performing a preset number of segmented roll-pulling operations based on the mill roll-changing command includes:
[0053] During the rolling process, the rolls are controlled to stop sequentially at a first preset position, a second preset position, and a third preset position, and remain stationary for a first preset duration at the first preset position, a second preset duration at the second preset position, and a third preset duration at the third preset position. The displacements of the first preset position, the second preset position, and the third preset position increase sequentially, and the stationary times of the first preset duration, the second preset duration, and the third preset duration decrease sequentially.
[0054] For example, during the roll-pulling process, the control roll is stopped sequentially at a first preset position, a second preset position, and a third preset position, maintaining a first preset static time at the first preset position, a second preset static time at the second preset position, and a third preset static time at the third preset position. The displacement at each preset position increases sequentially, while the static time decreases sequentially. Specifically, the solution is to switch to manual operation, intervening in three manual roll-pulling operations. When the automatic roll-pulling process reaches the step of removing the old roll, the operator in the control room, after the unit speed reaches 0 m / min, controls the roll to stop sequentially at different preset positions: the first stop position is 20 mm ± 10 mm with a static time of 3 seconds; the second stop position is 50 mm ± 10 mm with a static time of 2 seconds; and the third stop position is 70 mm ± 10 mm with a static time of 1 second. Through this segmented roll-pulling and brief pauses at different positions, the fluidity of the liquid on the surface of the old roll is increased by utilizing the pulling guide and the starting and stopping of the traction force. By segmenting the rolls and maintaining them stationary at different positions for a certain duration, and utilizing the guiding force and traction to start and stop, the fluidity of the liquid on the surface of the old rolls is increased. This allows the emulsion adhering to the roll surface to fall into the frame, effectively reducing the amount of emulsion carried out by the rolls and minimizing emulsion waste. The roll-pulling operation table is shown in Table 1.

[0056] Table 1
[0057] In some examples, the step of performing surface treatment on the upper surface of the roll bearing housing based on the roll optimization results to obtain the surface treatment result includes:
[0058] The upper surface of the roll bearing housing is cleaned to obtain the first surface;
[0059] The first surface is rough polished to obtain the second surface;
[0060] The second surface is then finely polished to obtain the third surface;
[0061] The third surface is subjected to anti-oxidation treatment to obtain a surface treatment result, so that the surface roughness of the upper plane of the roll bearing housing is reduced to a preset range.
[0062] For example, based on the optimization results of the roller drawing, the surface treatment of the upper surface of the roll bearing housing is divided into four steps. First, surface cleaning is performed by cleaning the entire bearing housing with a cloth and oil stain cleaner to restore the surface condition and obtain the first surface, at which point the roughness Ra (arithmetic mean deviation of profile) is ≥1.2μm. Next, a first polishing is performed, which is rough polishing. A polishing machine and a 400-inch flap wheel are used to rough polish all the metal on the upper surface to make the texture uniform and obtain the second surface, at which point the roughness Ra is ≥0.5μm. Then, a second polishing is performed, which is fine polishing. A polishing machine, abrasive, and a 800-inch polishing pad are used to fine polish all the metal on the upper surface to achieve a mirror effect and obtain the third surface, with a roughness Ra = 0.05-0.2μm. Finally, the third surface is subjected to anti-oxidation treatment by coating all the metal on the upper surface with a cloth and an anti-oxidant to obtain the surface treatment result, which delays rusting, and the roughness is also maintained at Ra = 0.05-0.2μm. In addition, periodic maintenance is required, using a polishing machine, abrasive compound, polishing pads (800 grit), cloth, and antioxidant. Maintenance should be performed every six months to maintain the surface roughness within a preset range, specifically Ra = 0.1-0.2 μm. The surface treatment parameters are shown in Table 2. Reducing the surface roughness of the upper surface increases the fluidity of the liquid, reduces the adhesion of emulsion to the bearing housing's upper surface, and thus reduces emulsion residue. Simultaneously, the antioxidant treatment can delay surface rusting, maintain surface roughness stability, and extend the service life of the bearing housing.
[0063]
[0064] Table 2
[0065] In some examples, the step of performing anti-oxidation treatment on the third surface to obtain the surface treatment result includes:
[0066] The third surface is coated with an antioxidant to obtain a surface treatment result, and the arithmetic mean deviation of the surface treatment result is maintained within a first preset range based on periodic maintenance operations.
[0067] For example, an antioxidant is applied to the third surface. Specifically, the antioxidant is applied evenly to all metal surfaces on the upper plane of the roll bearing housing using a cloth. The antioxidant forms a protective film on the metal surface, preventing oxygen, moisture, etc., from contacting the metal, thereby slowing down the oxidation and rusting process. Applying the antioxidant maintains the smoothness and stability of the third surface. In previous surface treatment steps, the surface roughness has been reduced to a first preset range (e.g., Ra = 0.05-0.2 μm). Oxidation and rusting will damage this smooth surface, leading to increased surface roughness, which in turn affects the flowability of the emulsion and increases the amount of residual emulsion. Therefore, the purpose of applying the antioxidant is to maintain a good surface condition, ensure smooth emulsion flow, and continuously reduce the amount of residual emulsion. The maintenance cycle is every six months.
[0068] Through anti-oxidation treatment and periodic maintenance, the oxidation and rust on the upper surface of the bearing housing can be effectively delayed, maintaining the smoothness and stability of the surface, ensuring that the emulsion can flow smoothly, continuously reducing the amount of emulsion residue, and reducing the problem of increased emulsion adhesion caused by surface oxidation.
[0069] In some examples, the step of chamfering the edges of the upper plane includes:
[0070] The edges and corners of the upper surface are polished to form a chamfer at a first preset angle, so that the length of the chamfer from the edge of the upper surface is within a second preset range.
[0071] For example, the edges of the upper surface are ground to form a chamfer with a first preset angle, such that the length of the chamfer from the edge of the upper surface is within a second preset range. The first preset angle is 20°-30°, and the second preset range is 1-2 mm. This chamfering process increases the liquid diffusion capacity of the bearing housing frame, allowing the emulsion to flow out more smoothly from the edge, reducing the accumulation of emulsion at the edge, and further reducing the residual amount of emulsion. At the same time, the reasonable chamfer angle and length range will not compromise the stability of the bearing housing, ensuring the normal operation of the equipment during high-speed rolling.
[0072] In some examples, the step of providing a guide structure for the edge region of the traveling slider track on the roll bearing housing includes:
[0073] Based on the second preset angle, the edge of the traveling slider track on the roller bearing seat is chamfered, and the coverage length of the copper slider on the traveling slider track is extended to match the plane of the traveling slider track.
[0074] For example, the track edge is chamfered based on a second preset angle, and the coverage length of the copper slider on the track is extended to match the track plane. The second preset angle is 45±2°. This is done in two steps: first, the track edge is chamfered at 45±2°, with the chamfer distance from the edge ranging from approximately 1 to 2 mm; second, the copper slider on the track is modified to increase its length and cover the entire plane (without overlapping the chamfer). By chamfering the track edge and modifying the copper slider, the guiding force for emulsion drainage in the track area is increased, shortening the emulsion's residence time in the track area, allowing for faster drainage, reducing emulsion residue on the track, and improving the cleanliness and operating efficiency of the equipment.
[0075] In some examples, the step of extending the coverage length of the copper slider on the walking slider track to match the plane of the walking slider track includes:
[0076] An inclined surface structure matching the chamfer of the walking slider track is added to both sides of the copper slider to enhance the guiding efficiency of the emulsion discharge.
[0077] For example, in the treatment of the traveling slider track of the roll bearing housing, an inclined structure matching the chamfer of the traveling slider track is added to both sides of the copper slider. That is, a chamfer of 45±2° is added to both sides of the copper slider to enhance the guiding efficiency of emulsion discharge. Since the traveling slider track is the lowest point of the bearing housing planar structure, emulsion tends to accumulate here. This inclined structure can provide a clear flow direction for the emulsion, guiding it to flow towards the edge of the track along the inclined surface, avoiding accumulation and stagnation. At the same time, the inclination angle of the inclined surface provides a component of gravity to accelerate the flow speed of the emulsion, reducing its residence time and adhesion to the track surface. In addition, the formed continuous and smooth flow path allows the emulsion to flow smoothly from above the track along the chamfer of the track edge and the inclined surfaces on both sides of the copper slider, thereby efficiently discharging the emulsion, reducing the amount of residue, and improving equipment cleanliness and operating efficiency.
