Description

Technical Field

[0001] The present invention relates to the field of steel processing, in particular to a multifunctional rolling machine for processing section steel. Background Art

[0002] H-beam is a common type of steel, also known as wide-flange rectangular steel. Its cross-section is similar to an H-shape. Currently, H-beam production involves heating the billet to a certain temperature in a calciner. The billet is then transported to a rolling mill for rolling. The rolled steel is then transported to a cooling area before being cut and shipped.

[0003] However, in the process of rolling the heated steel by the rolling wheels of the existing rolling equipment, the temperature of the rolling rollers will rise due to long-term continuous use. The excessively high temperature will easily cause the rolling wheels to deform, affecting the dimensional accuracy and surface quality of the steel forming. In addition, when the heated steel comes into contact with the air, the high-temperature steel will react with the oxygen in the air to form a layer of oxide scale on its surface. In the process of rolling the steel by the rolling rollers, some oxide scale debris will adhere to the rolling rollers, making the surface of the rolling rollers uneven, thereby affecting the size of the subsequent steel rolling forming.

DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0031] A multifunctional rolling mill for processing steel sections, such as Figure 1-5 As shown, it includes a fixed base 1, a conveying roller 2, an electric drive box 3, a rolling roller 4, a side rolling roller 5, a conveying roller 2 6 and a conveying roller 3 7; the fixed base 1 is rotatably connected to two conveying rollers 2; the fixed base 1 is fixedly connected to two electric drive boxes 3, and the electric drive boxes 3 are connected to the conveying roller 2; the fixed base 1 is rotatably connected to two rolling rollers 4, and the rolling roller 4 is connected to the electric drive box 3; the fixed base 1 is rotatably connected to two side rolling rollers 5; the fixed base 1 is rotatably connected to a plurality of conveying rollers 2 6; the fixed base 1 is rotatably connected to two conveying rollers 3 7;

[0032] It also includes a mounting plate 8, a water storage box 9, a sponge roller 10, an isolation plate 11 and a cleaning system; the fixed base 1 is fixedly connected to the mounting plate 8; the mounting plate 8 is fixedly connected to four water storage boxes 9 distributed in a rectangular shape, and the water storage boxes 9 correspond to the rolling roller 4 and the side rolling roller 5 respectively; each water storage box 9 is rotatably connected to a number of sponge rollers 10, and the sponge rollers 10 are in contact with the rolling roller 4 and the side rolling roller 5 respectively; each water storage box 9 is internally bolted with an isolation plate 11, and the isolation plate 11 has a number of through holes, and the sponge roller 10 is in contact with the cooling water inside the water storage box 9 through the through holes of the isolation plate 11, and the water absorption amount of the sponge roller 10 can be adjusted by setting the size of the through hole, thereby adjusting the cooling effect of the sponge roller 10 on the rolling roller 4 or the side rolling roller 5; the fixed base 1 is fixedly connected to the cleaning system.

[0033] It also includes a shovel plate 12 and a scraper bar 13; each sponge roller 10 is fixed with six scrapers 13, and the scraper bar 13 is made of high-temperature resistant rubber material; each water storage box 9 is fixed with a shovel plate 12, and the shovel plate 12 is in contact with the surface of the sponge roller 10.

[0034] It also includes a connecting pipe 101, a water inlet pipe 102, a water outlet pipe 103 and an atomizing nozzle 104; each adjacent water storage box 9 is connected by a connecting pipe 101, and a suction pump is provided in the connecting pipe 101; the upper connecting pipe 101 is connected to the water inlet pipe 102, and the water inlet pipe 102 is connected to the external conveying mechanism; the lower connecting pipe 101 is connected to the water outlet pipe 103, and a valve is provided in the water outlet pipe 103; each water storage box 9 is connected to a number of atomizing nozzles 104.

[0035] The baffle 105 is also included; the baffle 105 is fixedly connected to the surface of the water storage box 9 located above, and the baffle 105 is configured as a V-shaped plate.

[0036] The working steps of the above embodiment are as follows: during specific operation, the heated steel is placed between the conveyor rollers 1 and 2, and then the conveyor rollers 2 are controlled to rotate to convey the heated steel from left to right. When the heated steel passes through the rolling rollers 4 and the side rolling rollers 5, the electric drive box 3 is controlled to drive the rolling rollers 4 to rotate. While the rolling rollers 4 drive the steel to convey the steel to the right, the rolling rollers 4 and the side rolling rollers 5 cooperate with each other to roll the heated steel into H-shaped steel. The rolled H-shaped steel continues to be conveyed to the right through multiple conveyor rollers 2 and 3, and then the oxide scale debris on the surface of the H-shaped steel is cleaned and cooled by the cleaning system. Finally, the H-shaped steel is cut and conveyed out by the cutting equipment.

[0037] However, when the rolling roller 4 and the side rolling roller 5 are used continuously for a long time, the temperature of the rolling roller 4 and the side rolling roller 5 will increase. Excessive temperature will easily cause the rolling roller 4 and the side rolling roller 5 to deform, which will eventually affect the dimensional accuracy and surface quality of the steel forming; and the surface of the heated steel will react with the air to form a layer of oxide scale on its surface, so that during the rolling process of the rolling roller 4 and the side rolling roller 5, some oxide scale debris will adhere to the surface, resulting in uneven surface of the rolling roller 4 and the side rolling roller 5, which will affect the subsequent steel rolling forming quality; therefore, before rolling, the external conveying mechanism is manually controlled to convey the cooling water through the water inlet pipe 102 to the connecting pipe 101 and the water storage box 9, and then the electric drive is controlled. The box 3 drives the rolling roller 4 to rotate to roll the heated steel; during the rolling process, taking the upper rolling roller 4 as an example, as the electric drive box 3 drives the upper rolling roller 4 to rotate counterclockwise when viewed from the front to the back, the rolling roller 4 drives the sponge roller 10 in contact with it to rotate clockwise when viewed from the front to the back, and the sponge roller 10 contacts the cooling water inside the water storage box 9 through the through hole of the isolation plate 11 and absorbs the cooling water. When the rolling roller 4 drives the sponge roller 10 to rotate together, the surface of the rolling roller 4 is cooled by the cooling water absorbed by the sponge roller 10, and when the sponge roller 10 contacts the surface of the rolling roller 4, the sponge roller 10 can replenish the cooling water in time through the through hole of the isolation plate 11 to ensure that the sponge roller 10 can continue to cool the rolling roller 4 However, in the same way, when the rolling roller 4 and the side roller 5 cooperate with each other to roll the heated steel, the sponge roller 10 absorbs the internal cooling water of the water storage box 9 to continuously cool the rolling roller 4 and the side roller 5, so as to avoid the rolling roller 4 and the side roller 5 from continuously increasing in temperature when the rolling roller 4 and the side roller 5 are continuously rolled. Excessive temperature causes the rolling roller 4 and the side roller 5 to deform, and ultimately affects the dimensional accuracy and surface quality of the steel forming; when it is necessary to pay attention, the water absorption amount of the sponge roller 10 can be adjusted by replacing the isolation plate 11 with different through-hole sizes, thereby adjusting the cooling effect of the sponge roller 10 on the rolling roller 4 or the side roller 5; and, while cooling the rolling roller 4 and the side roller 5, the temperature in the connecting pipe 101 is controlled. The suction pump works to suck the cooling water in the connecting pipe 101 and the water storage box 9 through the suction pump, so that the cooling water forms a circulation flow in the connecting pipe 101 and the water storage box 9, so that the temperature of the cooling water in each connecting pipe 101 and the water storage box 9 is the same, ensuring the same cooling effect on each rolling roller 4 and the side roller 5, avoiding the situation where different temperatures appear when cooling the rolling roller 4 and the side roller 5, and different temperatures have different rolling effects on steel, which ultimately affects the rolling quality of steel; and when the cooling water needs to be discharged later, the valve of the water outlet pipe 103 can be controlled to open, and the pumping of the suction pump in the connecting pipe 101 can be coordinated to quickly discharge the cooling water in the connecting pipe 101 and the water storage box 9;

[0038] The scraping strips 13 on the sponge roller 10 are used to scrape the surface of the rolling roller 4 or the side rolling roller 5 while the sponge roller 10 is rotating and cooling. The scraping strips 13 on the sponge roller 10 can scrape the surface of the rolling roller 4 or the side rolling roller 5 to scrape off the oxide scale debris adhering to the surface, so as to prevent the oxide scale debris attached to the surface from affecting the subsequent rolling of the steel. At the same time, as the sponge roller 10 rotates, the shovel plate 12 is used to shovel and clean the sponge roller 10 and the scraping strips 13 to scrape off the oxide scale debris, so as to prevent the sponge roller 10 from adhering to too much oxide scale debris on the surface of the sponge roller 10, thereby affecting the cooling effect of the rolling roller 4 and the side rolling roller 5, and ensuring that the sponge roller 10 and the scraping strips 13 can be used repeatedly. A baffle 105 is provided on the water storage box 9 above. The debris cleaned by the shovel plate 12 will fall to the front and rear sides as blocked by the baffle 105, so as to ensure that the cleaned debris will not fall directly on the rolled steel below.

[0039] At the same time, after the heated steel is rolled into an H-shaped steel, as the H-shaped steel is conveyed to the right by the conveying roller 2 6, the atomizing nozzle 104 is controlled to spray cooling water on the surface of the formed H-shaped steel to perform preliminary cooling of the H-shaped steel. Subsequently, the H-shaped steel is thoroughly cooled by the cleaning system. The rolled H-shaped steel is preliminarily cooled by the atomizing nozzle 104 in the form of mist to prevent the H-shaped steel from cracking due to excessive temperature difference when it is directly cooled later. Example 2

[0040] On the basis of Example 1, Figure 6-8 As shown, the cleaning system includes a shielding cover 201, a rectangular tube 202, a high-pressure nozzle 203, a circular tube 204, a water pump 205, a rubber pad 206 and a collection box 211; the fixed base 1 is fixedly connected to the shielding cover 201, and the shielding cover 201 is located between the conveying roller 2 6 and the conveying roller 3 7; the fixed base 1 is fixedly connected to the collection box 211, and the collection box 211 is located on the lower side of the shielding cover 201; the shielding cover 201 has a feed port 201c on the left side and a feed port 201c on the right side. Discharge port 201b; the shielding cover 201 is fixedly connected to a rectangular tube 202; the rectangular tube 202 is connected to a number of high-pressure nozzles 203, and all the high-pressure nozzles 203 are arranged to be tilted to the right; the rectangular tube 202 is connected to a circular tube 204, and the circular tube 204 passes through the shielding cover 201; the fixed base 1 is fixedly connected to a water pump 205, and the water pump 205 is connected to the circular tube 204, and the suction part of the water pump 205 is connected to the collection box 211; a rubber pad 206 is provided at the discharge port 201b.

[0041] The right side of the shielding cover 201 is set as a V-shaped side plate 201a. When the high-pressure nozzle 203 cleans the oxide scale on the surface of the H-shaped steel and flushes it to the right, it can be guided to the front or rear side through the V-shaped side plate 201a, so that the cleaned oxide scale can fall from the front or rear side and be collected in the collection box 211.

[0042] The side plate 201a is fixed with the guide plate 221, and the guide plate 221 contacts the surface of the H-shaped steel. The guide plate 221 is tilted to the right and has a V-shaped shape.

[0043] A filter screen 212 is also included; the filter screen 212 is arranged in the collection box 211 .

[0044] On the basis of the above embodiment, when the rolled H-shaped steel passes through the preliminary cooling of the atomizing nozzle 104 and is conveyed to the right by the conveying roller 26, a layer of oxide scale will be formed on the surface of the H-shaped steel. When it is directly conveyed to the subsequent process, the oxide scale on the surface will affect the subsequent processing of the H-shaped steel; therefore, the H-shaped steel first enters the shielding cover 201 from the feed port 201c, then passes through the middle of the rectangular tube 202, is conveyed to the right, and passes through the discharge port 201b, and then is conveyed out by the conveying roller 3 7. When the H-shaped steel passes through the rectangular tube 202, the high-pressure nozzle 203 is controlled to flush the surface of the H-shaped steel to flush and clean the oxide scale on its surface to prevent the oxide scale layer on the surface of the H-shaped steel from affecting the subsequent The subsequent processing is affected, and water is flushed through the high-pressure nozzle 203 to thoroughly cool the H-shaped steel; and while cleaning, the entire cleaning area is shielded by the provided shielding cover 201 to intercept the cleaned debris and water, and finally collected in the collection box 211 on the lower side, to prevent the washed debris from splashing around during the flushing process of the high-pressure nozzle 203, resulting in the need to clean it later and increasing the labor of the staff; when the cleaned H-shaped steel passes through the discharge port 201b, the provided rubber pad 206 contacts the surface of the H-shaped steel, scraping off the debris and water on its surface, so that there will be no residual debris on the surface of the H-shaped steel when it passes through the discharge port 201b;

[0045] However, the H-shaped steel is in an "H" shape as a whole, and its upper side is concave. When flushing and cleaning, the debris in the concave portion of the upper side of the H-shaped steel is difficult to be flushed out. Therefore, during the flushing process of the high-pressure nozzle 203, the guide plate 221 is provided, and the guide plate 221 is fitted with the concave portion of the upper side of the H-shaped steel. Figure 6As shown, as the high-pressure nozzle 203 flushes the debris to the right, when the debris and water contact the guide plate 221, the debris and water washed over can be flushed out to the front or rear side respectively under the guidance of the guide plate 221, and finally collected in the collection box 211 on the lower side, and the debris in the depression on the upper side of the H-shaped steel is flushed out in time to prevent the debris there from being difficult to discharge; at the same time, the right side of the shielding cover 201 is set to a V-shaped side plate 201a, and when the high-pressure nozzle 203 cleans the oxide scale on the surface of the H-shaped steel and flushes to the right, the debris and water are ... The side plate 201a is set in a V-shape, which can guide the washed oxide scale debris and water to the front or rear side, so that the cleaned oxide scale can fall from the front or rear side and be collected in the collection box 211, thereby preventing the debris washed to the right from hitting the right side of the shielding cover 201 and rebounding back to the depression on the upper side of the H-shaped steel; and when the high-pressure nozzle 203 flushes water on the rubber pad 206, the debris scraped from the rubber pad 206 can be flushed to the front or rear side along the side plate 201a, thereby preventing excessive debris from accumulating on the surface of the rubber pad 206 and making it impossible to continue cleaning the H-shaped steel;

[0046] Moreover, when the scale debris and water flushed down are collected in the collection box 211, the scale debris is filtered through the filter screen 212 to separate the scale debris from the water. When the high-pressure nozzle 203 is working, the water collected in the collection box 211 is sucked by controlling the water pump 205, and is transported to the high-pressure nozzle 203 through the circular pipe 204 and the rectangular pipe 202, so that the water can be recycled and the waste of water resources is reduced. Example 3

[0047] On the basis of Example 2, Figure 9-11 As shown, it also includes an electric push rod 301, a scraper 302 and a hose 303; the shielding cover 201 is fixedly connected to two electric push rods 301; the telescopic parts of all the electric push rods 301 are commonly fixedly connected to a scraper 302, and the scraper 302 is in contact with the top of the shielding cover 201, and the scraper 302 is configured to be V-shaped; the scraper 302 is provided with a collecting trough 302a; a hose 303 is fixedly connected to the middle of the scraper 302, and the hose 303 is connected to the rectangular tube 202, and the hose 303 is connected to the collecting trough 302a.

[0048] It also includes a pressing plate 304, a movable plate 305 and a water diversion trough 306; the collecting trough 302a has a plurality of notches 302b; each notch 302b is rotatably connected to a movable plate 305 via a torsion spring; the side plate 201a is fixedly connected to a plurality of pressing plates 304, and the pressing plates 304 are flush with the movable plates 305; the scraper 302 is fixedly connected to a plurality of water diversion troughs 306, and the water diversion troughs 306 are located below the notches 302b.

[0049] On the basis of the above embodiment, the oxide scale debris is flushed to the right by the high-pressure nozzle 203, and the shielding cover 201 shields the entire cleaning area to prevent the washed debris from splashing everywhere. Some debris will adhere to the shielding cover 201 under the action of water, and if there are too many debris adhering to the debris shielding cover 201, the debris will always fall back onto the H-shaped steel, thereby increasing the subsequent cleaning intensity; therefore, during the cleaning process, the electric push rod 301 is regularly controlled to drive the scraper 302 to move to the right, and the scraper 302 moves to scrape off and clean the debris attached to the top of the shielding cover 201, and collect it in the collection tank 302a, and When the water pump 205 inputs water into the rectangular tube 202, the water simultaneously flows into the collection tank 302a through the hose 303, flushing the debris collected in the collection tank 302a toward the front and rear sides respectively, and then collecting it in the collection box 211 below, to prevent excessive debris from being collected in the collection tank 302a and eventually falling back onto the H-shaped steel below. When the water flows out from the front and rear sides of the collection tank 302a, it is guided by the V-shaped scraper 302 to flow into the front and rear side walls of the shielding cover 201, flushing and cleaning the front and rear side walls of the shielding cover 201, and cleaning the front and rear side walls of the shielding cover 201.

[0050] And when the scraper 302 continues to move to the right and approaches and contacts the pressing plate 304, the pressing plate 304 presses the movable plate 305. As the scraper 302 continues to move to the right, the movable plate 305 is pressed and rotated, so that the gap 302b is opened, and then the water flowing in the collecting tank 302a flows out from the gap 302b, and under the guidance of the water diversion tank 306, the water can also flow into the surface of the side plate 201a, flushing and cleaning the surface of the side plate 201a, washing away the oxide scale debris adhering to its surface, cleaning the entire shielding cover 201, and completely removing the oxide scale debris flushed down.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
