Description

Technical Field

[0001] This invention relates to the field of special stainless steel smelting, and specifically to a steel ingot rolling mill for supporting steel ingots. Background Technology

[0002] In the smelting of special stainless steel, steel ingots produced from consumable furnaces and electroslag furnaces need to be welded or ground. These ingots are generally relatively short and thick, ranging from 1.5 to 3.8 meters in length. For welding or grinding round ingots, a crane is used to transport them to a support device before welding or grinding. Some cylindrical ingots need to be turned during welding or grinding, requiring additional equipment or tools for turning or rolling them. Existing support devices present several safety hazards. First, the small lateral bearing surface necessitates repeated adjustments by the crane for precise hoisting, sometimes requiring manual pulling to the support device for accurate placement. Second, due to the ingots' weight, any mishap could cause them to detach from the support device and fall, potentially injuring auxiliary equipment such as motors, nearby workers, or other equipment used for turning. Summary of the Invention

[0003] In view of the problems in the related technologies, the present invention proposes a steel ingot rolling mill for supporting steel ingots, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0004] Therefore, the specific technical solution adopted by the present invention is as follows:

[0005] A steel ingot rolling mill for supporting steel ingots includes a support base, at least two symmetrically arranged and parallel support seats on the support base, rollers on the support seats, and a motor for driving the rollers to rotate. The motor is located on the support base and beside the support seats. Each support seat has two rollers with parallel axles, and the axis lines of the rollers on corresponding sides of the two support seats coincide. The motor drives at least one roller to rotate through a transmission chain. A groove is provided at the center of the top of the support seat. The upper ends of the rollers located on both sides of the groove extend beyond the top edge of the groove. The support seat has a protective guide assembly at least on the side facing the motor. The protective guide assembly includes a motor protection kit for protecting the motor and / or a steel ingot guide kit provided at at least one end of each support seat. A secondary support is provided on the top of the support base, and the motor is located on the secondary support.

[0006] The roller includes a drive wheel that is connected to the motor and a driven wheel that can be driven by a steel ingot. The drive wheel is connected to a transmission gear that is sleeved with the transmission chain via a rotating shaft. The transmission gear is located on the outside of the support seat facing away from the other support seat.

[0007] During operation, a crane lifts the steel ingot to a position above the support base, then releases it onto the base. The ingot is automatically positioned between the rollers on either side and the settling trough. When the ingot needs to be turned, the motor is activated, driving the rollers via a transmission chain, thus rotating the ingot. The raised platform ensures a flat bottom for the entire system. Furthermore, the secondary support base allows the motor to operate independently, not directly connected to the support base. The protective guide assembly guides the ingot and protects other components of the equipment.

[0008] Generally, the motor is directly fixed to the side of the support base via some brackets. However, due to the weight of the steel ingot and the large pulling force during motor operation, the brackets used to install the motor are prone to tilting, resulting in loosening of the steel ingot drive chain. This application adopts a secondary bracket mounted on a raised platform, so that there is no fixed connection between the motor and the support base, only a contact relationship. The setting of the raised platform and the secondary bracket makes the motor base stable, thereby ensuring that the motor is not prone to tipping over or falling off the platform, and ensuring long-term effective use.

[0009] The motor can be connected to only one roller as the driving wheel, while the other rollers can act as driven wheels, rotating with the steel ingot. Alternatively, an additional wheel system and transmission chain can be added so that the driven wheels can also rotate actively with the driving wheel via the transmission chain. However, due to the weight of the steel ingot, if both rollers on both sides are designed to be motor-driven, slippage, loss of synchronization, or the motor being unable to pull them properly may occur during long-term use. Furthermore, if the motor rotates too fast, it is more likely to push the steel ingot out of the receiving position, posing a danger. Therefore, using a single roller as the driving wheel is safer and more practical.

[0010] Preferably, the motor protection kit includes a connecting rod connecting the two support seats, a guarding component located above the motor, and a vertical stop located outside the motor. The guarding component spans above the motor, and the front and rear ends of the guarding component are respectively connected to the connecting rod and the vertical stop. The upper end of the vertical stop extends beyond the guarding component to form a vertical stop portion, and the lower end of the vertical stop is connected to the secondary frame.

[0011] Preferably, the protective component is an arc-shaped rod or arc-shaped plate that gradually extends downward from the inner end to the outer end, or a cover box that can cover the main body of the motor. The arc-shaped rod or arc-shaped plate has its arc opening facing downward, and side ribs are vertically connected to both sides of the arc-shaped rod or arc-shaped plate. The top edge of the side ribs is consistent with the arc of the arc-shaped rod, and the height of the upper end of the vertical stop exceeds the height of the top edge of the side ribs.

[0012] The protective components protect the motor and guide the steel ingot. The upright design prevents the ingot from slipping and falling, enhancing safety. The components are also highly robust. The raised, curved plate provides even greater strength and better protection for the motor, preventing it from bending downwards and damaging the motor under the weight of the ingot.

[0013] Preferably, the guarding component is hinged to the connecting rod, and the inner side of the upright is provided with an abutment platform, which is detachably connected to the guarding component.

[0014] The above structure provides excellent protection for the motor while also making installation convenient. Disassembly can be performed simply by flipping up the protective components.

[0015] Preferably, the support base is a flat frame structure with an open top. Through holes or frame grooves are correspondingly provided on the wide frame plates on the front and rear sides of the support base. The lower part of the roller is embedded in the frame groove of the support base and is provided on the support base through the through holes or frame grooves. A ash guide rib is inclinedly provided on the inner wall of the support base. The ash guide rib gradually slopes downward from the side closer to the motor to the side farther away from the motor or gradually slopes downward from the center to both sides. Ash outlets are provided on the side frame plates of the support base that connect to the lower end of the ash guide rib and / or on the side plates on the front and rear sides of the support base.

[0016] The aforementioned structure provides high strength and strong support for the support base and rollers. However, it easily accumulates dust and debris inside the frame, especially dust generated during grinding. The dust guide ribs enhance the strength of the support base while also guiding the dust. Dust and debris slide down the guide ribs to the dust outlet for automatic discharge, facilitating manual sweeping or blowing. Furthermore, the dust outlet directs the dust away from the motor, effectively reducing the impact of dust and debris on the motor. This makes cleaning more convenient and increases the equipment's strength.

[0017] Preferably, the steel ingot guide kit includes a guide wing portion located at the top of the side end of the support base and extending outward and upward, and a support portion connected to the bottom of the guide wing portion, the bottom of the support portion being located on the elevated base.

[0018] The guide wing design expands the lateral bearing surface of the support, reducing the precision required for overhead crane lifting. Even if the steel ingot falls onto the guide wing, it can be smoothly guided between the rollers. Furthermore, the guide wing does not need to be excessively large and will not obstruct workers during grinding. A support structure at the bottom of the guide wing ensures high-strength support. After the steel ingot is placed in position, the guide wing can also serve as a support for the workers, allowing them to perform grinding or welding more safely and effortlessly.

[0019] Preferably, the guide wing is hinged to the support base;

[0020] The support part is a hydraulic cylinder hinged to the bottom of the guide wing part;

[0021] Alternatively, a buffer spring may be fitted onto the support portion. The support portion includes an upright and / or diagonal brace. The elevated base is provided with a guide portion that fits and passes through the support portion. A guide groove is formed inside the guide portion. The bottom of the support portion is located within the guide groove. The buffer spring is fitted onto the opening of the guide groove. When the lower end of the support portion abuts against the bottom of the guide groove, the support portion is perpendicular to the edge of the groove opening. The outer diameter of the buffer spring is larger than the width of the guide hole in the guide groove. A guide groove adapted to the buffer spring is provided on the edge of the guide groove opening. The guide wing is an outwardly extending guide rod. The top of both sides of the support base is provided with hinge ears with an arc-shaped outer edge and a top edge that gradually rises from the inside to the outside. The guide rod is hinged to the hinge ears. The above-mentioned hinge ear structure is designed to facilitate a smooth arc transition at the connection position between the guide wing and the support base, ensuring that the steel ingot can be smoothly guided between the rollers when it falls onto the guide wing.

[0022] The support unit can be a hydraulic cylinder or a support structure with a buffer spring. Combined with the hinged guide vane, this ensures good cushioning force as the steel ingot falls, enhancing safety. Furthermore, as the ingot rolls towards the roller with the guide vane, the guide vane, under the action of the upper support unit, can slowly push upwards, further assisting in guiding the ingot into the settling tank, making it safer and more effective. The inclusion of the guide vane significantly improves the strength of the guide vane and support unit, ensuring long-term effective vertical movement and extending service life.

[0023] Preferably, when the support includes a diagonal brace, a limiting apex is provided in the guide groove, and the bottom end of the diagonal brace can abut against the limiting apex to limit the downward movement of the diagonal brace.

[0024] The above structure achieves triangular support, resulting in high structural strength and good stability.

[0025] Preferably, the bottom end of the support is fitted with a silent buffer sleeve and / or the limiting apex is covered with a rubber pad.

[0026] The above-mentioned structure achieves the effect of being as quiet as possible, while also dispersing and buffering the impact force, making the equipment more stable and safer to use.

[0027] Preferably, the bottom of the support portion is provided with a tapered blunt support foot that gradually widens from top to bottom, and the maximum outer diameter of the bottom of the blunt support foot is greater than the width of the guide groove.

[0028] Preferably, a top steel buffer seat is provided between adjacent support seats or on the front or rear side of the support seat. The top steel buffer seat includes an elastic buffer component at the bottom and a steel bearing seat at the top with a wavy top surface. The top surface of the steel bearing seat is a steel bearing surface with two crests and one trough. The trough corresponds to the settling trough, and the top of the crest is higher than the top of the roller.

[0029] The top steel buffer seat is used to cushion the impact on the steel ingot upon first contact, thereby reducing the impact force on the rollers. This ensures that the rollers are not easily deformed and the axle is not easily broken. Furthermore, the surface of the steel ingot is less damaged. Even if the steel ingot falls from a relatively high distance onto the support seat in case of an error, it is not easy to damage the steel ingot or equipment, making operation safer. The setting of the protective guide component and the top steel buffer seat increases the bearing surface in both the longitudinal and lateral directions, greatly reducing the difficulty of overhead crane lifting and also increasing safety.

[0030] The beneficial effects of this invention are as follows:

[0031] 1. During operation, the steel ingot is hoisted to the top of the support base by an overhead crane, then released and placed on the support base. The ingot is automatically positioned between the two rollers using the cooperation of the rollers and the settling trough. When the ingot needs to be turned, the motor is started, driving the rollers through the transmission chain, thus rotating the ingot. The raised platform ensures a flat bottom for the entire equipment. Additionally, the secondary platform allows the motor to operate independently, not directly connected to the support base. The protective guide assembly guides the ingot and protects other components of the equipment. The top steel buffer seat cushions the ingot upon initial contact, reducing impact on the rollers and preventing deformation or axle breakage. This minimizes surface damage to the ingot, reducing the risk of injury even if the ingot falls from a relatively high distance onto the support base. Operation is safer. The protective guide assembly and top steel buffer seat increase the contact area both longitudinally and laterally, significantly reducing the difficulty of overhead crane hoisting and increasing safety. Steel ingots produced by electroslag remelting furnaces are short and heavy, placing significant pressure on the supporting structure. Therefore, the strength requirements for the supporting structure are relatively high. If the ingot falls from an excessive height or is misaligned, it poses a considerable risk to the supporting equipment. The structure described in this application significantly improves the strength of the supporting structure, effectively reducing the accident and failure rates. This enhances safety and efficiency during production.

[0032] 2. This application achieves high overall load-bearing strength and good stability through the cooperation of various components, making each part less prone to damage and with a long service life. Moreover, it is convenient and safe for workers to operate the equipment, whether for crane operation, grinding, or welding. Attached Figure Description

[0043] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0044] Example 1;

[0045] A steel ingot rolling mill for supporting steel ingots includes a support base 1, at least two symmetrical and parallel support seats 2 disposed on the support base 1, rollers 3 disposed on the support seats, and a motor 4 for driving the rollers to rotate. The motor 4 is disposed on the support base and located beside the support seats 2. Each support seat 2 is provided with two rollers 3 with parallel axles, and the axis lines of the rollers 3 on the corresponding sides of the two support seats 2 coincide. The motor 4 drives at least one roller 3 to rotate through a transmission chain 41. A groove 21 is provided at the top center of the support seat 2. The upper ends of the rollers 3 located on both sides of the groove 21 extend beyond the top edge of the groove 21. The support seat 2 is provided with a protective guide assembly at least on the side facing the motor 4. The protective guide assembly includes a motor protection kit for protecting the motor disposed on the side facing the motor 4 and / or a steel ingot guide kit disposed on at least one side of each support seat. A secondary support base 12 is provided on the top of the support base, and the motor is disposed on the secondary support base.

[0046] The roller 3 includes a driving wheel 31 that is connected to the motor 4 and a driven wheel 32 that can be driven by a steel ingot. The driving wheel 31 is connected to a transmission gear that is sleeved on the transmission chain 41 via a rotating shaft. The transmission gear is located on the outside of the support seat facing away from the other support seat.

[0047] Generally, the motor is directly fixed to the side of the support base via some brackets. However, due to the weight of the steel ingot and the large pulling force during motor operation, the brackets used to install the motor are prone to tilting, resulting in loosening of the steel ingot drive chain. This application adopts a secondary bracket mounted on a raised platform, so that there is no fixed connection between the motor and the support base, only a contact relationship. The setting of the raised platform and the secondary bracket makes the motor base stable, thereby ensuring that the motor is not prone to tipping over or falling off the platform, and ensuring long-term effective use.

[0048] The motor can be connected to only one roller as the driving wheel, while the other rollers can act as driven wheels, rotating with the steel ingot. Alternatively, an additional wheel system and transmission chain can be added so that the driven wheels can also rotate actively with the driving wheel via the transmission chain. However, due to the weight of the steel ingot, if both rollers on both sides are designed to be motor-driven, slippage, loss of synchronization, or the motor being unable to pull them properly may occur during long-term use. Furthermore, if the motor rotates too fast, it is more likely to push the steel ingot out of the receiving position, posing a danger. Therefore, using a single roller as the driving wheel is safer and more practical.

[0049] Example 2:

[0050] The difference from the above embodiment lies in that the motor protection kit includes a connecting rod 5 connecting the two support seats 2, a protective component 6 located above the motor 4, and a vertical stop 61 located outside the motor. The protective component 6 spans above the motor 4, and its front and rear ends are respectively connected to the connecting rod and the vertical stop. The upper end of the vertical stop extends beyond the protective component to form a vertical stop portion 611, and the lower end of the vertical stop is connected to the secondary frame. The connecting rod can be not only rod-shaped, but also an inclined plate-shaped structure that gradually extends downward from the side closer to the motor to the side farther away from the motor. Thus, it can serve as a connecting rod while also acting as a connecting rib between the two support seats, increasing the compressive strength of the support seats against lateral deviation. At the same time, the inclined plate-shaped connecting rod can also guide some dust or falling steel ingots or heavy objects to the side without the motor, which also provides protection for the motor.

[0051] Example 3:

[0052] The difference from the above embodiments is that the protective component is an arc-shaped rod or arc-shaped plate that gradually extends downward from the inner end to the outer end, or a cover box that can cover the main body of the motor. The arc-shaped rod or arc-shaped plate has its arc opening facing downward. Side ribs 62 are vertically connected to both sides of the arc-shaped rod or arc-shaped plate. The top edge of the side ribs is consistent with the arc of the arc-shaped rod. The height of the upper end of the vertical stop 61 exceeds the height of the top edge of the side ribs.

[0053] The protective components protect the motor and guide the steel ingot. The upright design prevents the ingot from slipping and falling, enhancing safety. The components are also highly robust. The raised, curved plate provides even greater strength and better protection for the motor, preventing it from bending downwards and damaging the motor under the weight of the ingot.

[0054] Example 4:

[0055] The difference from the above embodiment is that the guarding component is hinged to the connecting rod 5, and the inner side of the upright guard is provided with an abutment 612, which is detachably connected to the guarding component.

[0056] The above structure provides excellent protection for the motor while also making installation convenient. Disassembly can be performed simply by flipping up the protective components.

[0057] Example 5:

[0058] The difference from the above embodiment is that the support base 2 is a flat frame structure with an open top. Through holes or slots are correspondingly provided on the wide frame plates on the front and rear sides of the support base 2. The lower part of the roller 3 is embedded in the frame slot of the support base and is mounted on the support base through the through holes or slots. A guide rib platform 22 is inclinedly provided on the inner wall of the support base. The guide rib platform gradually slopes downwards from the side closer to the motor to the side farther away from the motor, or gradually slopes downwards from the center to both sides. A dust outlet 23 is provided on the side frame plate connecting the lower end of the guide rib platform and / or on the side plates on the front and rear sides of the support base. For support bases not connected to the motor, the guide rib platform can be a structure that is high in the middle and low at both ends. A dust outlet can be provided on both sides of the support base or on the front and rear surfaces of both sides.

[0059] The aforementioned structure provides high strength and strong support for the support base and rollers. However, it easily accumulates dust and debris inside the frame, especially dust generated during grinding. The dust guide ribs enhance the strength of the support base while also guiding the dust. Dust and debris slide down the guide ribs to the dust outlet for automatic discharge, facilitating manual sweeping or blowing. Furthermore, the dust outlet directs the dust away from the motor, effectively reducing the impact of dust and debris on the motor. This makes cleaning more convenient and increases the equipment's strength.

[0060] Example 6:

[0061] The difference from the above embodiments is that the steel ingot guide kit includes a guide wing 71 that is provided on the top of the side end of the support seat and extends outward and upward, and a support 72 that is connected to the bottom of the guide wing. The bottom of the support 72 is provided on the elevated seat.

[0062] The guide wing design expands the lateral bearing surface of the support, reducing the precision required for overhead crane lifting. Even if the steel ingot falls onto the guide wing, it can be smoothly guided between the rollers. The guide wing does not need to be excessively large and will not obstruct grinding operations. A support at the bottom of the guide wing ensures high-strength support. After the steel ingot is placed in position, the guide wing can also serve as a support for the worker's body, allowing for safer and more effortless grinding or welding. Additionally, abutment plates can be installed on the sides of the structure formed by the guide wing and support, and / or a flat plate can be installed on the top of the guide wing for better support or to place tools. The guide wing is hinged to the support base.

[0063] Example 7:

[0064] The difference from the above embodiment is that the support part is a hydraulic cylinder hinged to the bottom of the guide wing part.

[0065] Example 8:

[0066] The difference from the above embodiment is that a buffer spring 73 is sleeved on the support part, the support part includes a vertical pole and / or a diagonal brace, the elevated seat is provided with a guide part 74 that fits through the support part, the guide part has a guide groove 741, the bottom of the support part is located in the guide groove, the buffer spring is sleeved on the groove opening of the guide groove, when the lower end of the support part abuts against the bottom of the guide groove, the support part is perpendicular to the groove opening edge, the outer diameter of the buffer spring is larger than the hole width of the guide hole of the guide groove, the groove opening edge of the guide groove is provided with a guide groove 742 that matches the buffer spring, the guide wing part is an outwardly extending guide rod, the top of both sides of the support seat is provided with a hinge ear 24 with an arc-shaped outer edge and the top edge gradually rises from the inside to the outside, the guide rod is hinged to the hinge ear. The aforementioned hinged lug structure facilitates a smooth, rounded transition at the connection point between the guide wing and the support, ensuring that the steel ingot can be smoothly guided between the rollers when it falls onto the guide wing. When the support includes a diagonal brace, a limiting apex angle 8 is provided within the guide groove, and the bottom end of the diagonal brace can abut against the limiting apex angle to limit its downward movement. This structure achieves triangular support, resulting in high structural strength and good stability.

[0067] The support unit can be a hydraulic cylinder or a support structure with a buffer spring. Combined with the hinged guide vane, this ensures good cushioning force as the steel ingot falls, enhancing safety. Furthermore, as the ingot rolls towards the roller with the guide vane, the guide vane, under the action of the upper support unit, can slowly push upwards, further assisting in guiding the ingot into the settling tank, making it safer and more effective. The inclusion of the guide vane significantly improves the strength of the guide vane and support unit, ensuring long-term effective vertical movement and extending service life.

[0068] Example 9:

[0069] The difference from the above embodiment is that the support part can be two support columns with springs that can only move up and down, or two hydraulic cylinders. Guide wing guide grooves 711 can be provided on both sides of the top of the support seat. The guide wing can move up and down within the guide wing guide groove. When the steel ingot is lowered, with the buffering effect of the support column hydraulic cylinders, the guide wing moves downward along the guide wing guide groove and rests against the bottom of the groove. Then the steel ingot rolls to the working position of the roller. The top edge of the guide wing guide groove and the upper edge of the inner end of the guide wing are made into appropriate arc-shaped guide edges to facilitate the smooth rolling down of the steel ingot. When the guide wing rests against the bottom of the guide wing guide groove, the upper edge of the inner end of the guide wing is higher than or flush with the corresponding top edge of the corresponding guide wing guide groove.

[0070] Example 10:

[0071] The difference from the above embodiment is that the bottom end of the support is fitted with a silent buffer sleeve 74 and / or the limiting apex is covered with a rubber pad. The above structure not only achieves the effect of minimizing noise, but also plays a role in dispersing impact force and providing good cushioning, making the equipment more stable and safer to use.

[0072] Example 11:

[0073] The difference from the above embodiment lies in that the bottom of the support portion is provided with a tapered blunt support foot 721 that gradually widens from top to bottom. The maximum outer diameter of the bottom of the blunt support foot 721 is greater than the width of the guide groove, and the outer side of the top of the crest section of the bearing steel surface 93 extends outward and downward below the two sides of the support seat. The blunt support foot increases the bottom support surface, resulting in higher support strength, better stability, and safer use.

[0074] Example 12:

[0075] The difference from the above embodiment lies in the addition of a top steel buffer seat between adjacent support seats or on the front or rear side of the support seats. The top steel buffer seat includes an elastic buffer component 91 at the bottom and a steel bearing seat 92 at the top with a wavy top surface. The top surface of the steel bearing seat is a steel bearing surface 93, which has two crests and one trough. The trough corresponds to the settling groove, and the top of the crest is higher than the top of the roller. A buffer seat groove 94 can be provided on the elevated support, with the elastic buffer component 91 disposed within it. The steel bearing seat can move up and down along the buffer seat groove 94. The elastic buffer component can be a hydraulic cylinder. The steel bearing surface is slightly higher than the top surface of the roller. When the ingot is lowered, its own weight will press the steel bearing surface down until the top of the roller touches the surface of the ingot. Then, the hydraulic cylinder can further lower the position of the steel bearing surface so that it does not contact the ingot, thus facilitating subsequent rotation of the ingot. Alternatively, multiple raised ribs can be installed on the steel ingot's bearing surface along a direction perpendicular to its length to support the ingot while reducing the contact area between the ingot and the bearing surface, thus lowering friction. During operation, a crane lifts the ingot to the top of the support base, then releases it onto the base. The ingot automatically positions itself between the rollers on both sides, along with the settling trough. When the ingot needs to be turned, the motor is activated, driving the rollers via a transmission chain, thereby rotating the ingot. The raised support ensures a flat bottom for the entire system. Furthermore, the secondary support allows the motor to operate independently, not directly connected to the support base. A protective guide assembly guides the ingot and protects other components of the equipment. The top steel buffer seat is used to cushion the impact on the steel ingot upon initial contact, thereby reducing the impact force on the rollers. This ensures that the rollers are less prone to deformation and the axle is less likely to break. Furthermore, it minimizes surface damage to the steel ingot, reducing the risk of damage to the ingot or equipment even if it falls from a relatively high distance onto the support seat in an accidental event. This makes operation safer. The protective guide assembly and the top steel buffer seat increase the bearing surface both longitudinally and laterally, significantly reducing the difficulty of overhead crane lifting and increasing safety. This invention is primarily used for grinding or welding short, thick cylindrical steel ingots, such as those 1.5-3.8 meters in length. It can also be applied to oblong steel ingots of suitable length and diameter that can be mounted on the equipment described in this application.
