Description

Technical Field

[0001] This utility model relates to the field of steelmaking technology, and in particular to a billet slag cleaning machine based on steelmaking operations. Background Technology

[0002] During steelmaking, after smelting, casting, or cutting, a large amount of high-temperature slag adheres to the surface and edges of the steel billet. If this slag is not cleaned in time, it will directly affect the smooth progress of subsequent rolling processes, leading to defects such as scratches and slag inclusions on the billet surface, reducing the quality of steel products, and in severe cases, causing rolling mill jams, production interruptions, and increased production costs. Therefore, billet slag cleaning is an indispensable and critical link in the steelmaking process. The cleaning efficiency, cleaning effect, and operational stability of slag cleaning equipment directly affect the overall capacity and product qualification rate of the steelmaking production line.

[0003] Currently, the billet slag cleaning equipment used in steelmaking operations is mainly divided into two categories: manual cleaning and mechanical cleaning. Existing mechanical cleaning equipment mostly adopts a traction structure, using a traction mechanism to drive cleaning components to scrape or collect the slag from the billet surface. However, this type of equipment has many technical shortcomings in practical applications and is difficult to meet actual production needs.

[0004] First, in most mechanical slag cleaning equipment, slag collection and inner wall cleaning are two independent processes, requiring two separate drive mechanisms to achieve slag dumping and scraping of residue from the inner wall of the collection cylinder. This not only increases the complexity of the equipment structure and manufacturing costs but also leads to problems with smooth operation, resulting in low cleaning efficiency and the inability to achieve continuous slag cleaning. Second, the slag collection cylinders in existing equipment mostly use a single frame for support and fixation, which lacks stability. During traction, movement, and slag dumping, the collection cylinder is prone to shifting and shaking, affecting the smoothness of slag dumping and potentially causing high-temperature slag leakage, leading to safety accidents.

[0005] In view of the shortcomings of the existing technology, there is an urgent need to develop a billet slag cleaning equipment with reasonable structure, stable operation, high cleaning efficiency and convenient maintenance, so as to solve the problems of complex structure, incomplete cleaning, unstable operation, great safety hazards and high operation and maintenance costs of the existing equipment, and meet the actual needs of steelmaking production. Utility Model Content

[0006] The purpose of this invention is to provide a billet slag cleaning machine based on steelmaking operations to solve the aforementioned problems.

[0007] The objective of this utility model can be achieved through the following technical solution: a billet slag cleaning machine based on steelmaking operations, comprising a traction mechanism and a slag cleaning mechanism connected to the traction end of the traction mechanism. The slag cleaning mechanism includes a support drive frame, a slag collecting cylinder fixedly connected inside the support drive frame, a wall scraper rotatably connected inside the slag collecting cylinder, and a drive component connected between the wall scraper and the traction mechanism. The drive component can simultaneously perform two actions: first, drive the support drive frame to rotate the slag collecting cylinder to pour out the slag inside the cylinder; second, drive the wall scraper to move synchronously to scrape off the residual slag attached to the inner wall of the slag collecting cylinder.

[0008] Preferably, the support drive frame is composed of a support frame and a restraint frame fixedly connected together. The support frame is rotatably connected to the traction machinery through a pin structure, and the restraint frame is fixedly connected to the molten slag collection cylinder for limiting and fixing the molten slag collection cylinder.

[0009] Preferably, the wall scraping component includes a wall scraping shaft frame and an expansion ring fixedly connected to one end thereto. The outer wall of the expansion ring is provided with a plurality of vibration grooves at equal intervals along the axial direction. A plurality of striking rods are evenly arranged outside the plurality of vibration grooves. The striking rods are connected to the slag collecting cylinder. The wall scraping shaft frame is connected to the driving component for transmission, and is driven to rotate by the driving component.

[0010] Preferably, the striking rod adopts an elastic telescopic structure, which consists of a telescopic shaft and an elastic element; the friction contact end between the striking rod and the vibration groove is set with a rounded corner structure to avoid scratching the expansion ring and wear on itself.

[0011] Preferably, the driving component includes a limiting slide frame, an arc rod, a transmission arc plate, a transmission gear, and an output component;

[0012] The limiting slide frame is fixedly connected to the side wall of the traction machinery and is used to limit and guide the arc rod;

[0013] The arc rod is rotatably connected to the shaft of the scraper frame and slides with the limiting slide frame. A meshing groove is provided on one side of the arc rod, which can be adapted to the output component for transmission.

[0014] The transmission arc plate is fixedly connected to one side of the limiting slide frame, and its surface is provided with a meshing groove, which can be matched with the transmission gear.

[0015] The transmission gear adopts a bevel gear structure and is fixedly connected to the end of the scraper shaft frame, meshing with the meshing groove of the transmission arc plate for transmission.

[0016] The output component is a servo motor, which is fixedly connected to the end of the limiting slide frame. The output end of the servo motor is connected to an output gear, which meshes with the meshing groove of the arc rod to realize power output.

[0017] Preferably, the rotation axes of the transmission arc plate, arc rod, and supporting drive frame coincide to ensure smooth transmission and avoid jamming or offset.

[0018] The beneficial effects of this utility model are:

[0019] This invention uses a single drive unit to simultaneously complete the tilting and slag scraping of the slag collection cylinder and the inner wall scraping, eliminating the need for two drive mechanisms, simplifying the equipment structure, reducing manufacturing costs, and enabling continuous slag cleaning operations, thus significantly improving cleaning efficiency. Furthermore, the support drive frame, which combines a support frame and a restraint frame, provides double-limited fixation for the slag collection cylinder, ensuring no deviation or shaking during traction movement and tilting, preventing high-temperature slag leakage, eliminating safety hazards, improving equipment operational stability, and reducing maintenance costs.

[0020] This utility model's wall scraping component, combined with an elastic telescopic striking rod and a vibration groove, generates vibration while scraping slag, thoroughly removing stubborn residual molten slag from the inner wall for a more thorough cleaning. The rounded corner design also reduces component wear and extends the equipment's service life. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: The application background of this utility model is the high-temperature slag cleaning operation after steel billet cutting and casting in the steelmaking production line. The slag cleaning adopts a mechanical traction continuous operation. The technical solution of this utility model is to solve the problem of how to use a single drive to synchronously realize slag dumping and inner wall residue cleaning, and improve the fixed stability of the collection cylinder.

[0030] Please see Figures 1-5 This embodiment is a billet slag cleaning machine based on steelmaking operations, including: a traction mechanism 1 as the carrier for the movement and power of the whole machine, the traction end of which is rotatably connected to the support drive frame 2 through a pin shaft; the support drive frame 2 is welded and fixed by a support frame 21 and a restraint frame 22, the restraint frame 22 hugs the outer wall of the slag collection cylinder 3 to achieve rigid fixation of the collection cylinder and prevent shaking during operation; the slag collection cylinder 3 is a cylindrical high-temperature resistant cylinder used to collect the high-temperature slag scraped off the surface of the billet; a wall scraper 4 is rotatably installed in the center of the slag collection cylinder 3, the wall scraper shaft frame 41 of the wall scraper 4 passes through both ends of the cylinder, and the shaft end is connected to the drive component 5.

[0031] After the output component 55 of the drive component 5 is started, the output gear drives the arc rod 52 to slide in an arc along the limiting slide frame 51. The arc rod 52 drives the scraping shaft frame 41 to move synchronously, thereby pulling the support drive frame 2 to rotate around the pin shaft. The slag collection cylinder 3 tilts along with it, and the slag collected in the cylinder is poured outward under the action of gravity. At the same time, the transmission gear 54 at the end of the scraping shaft frame 41 meshes and rolls along the fixed transmission arc plate 53, forcing the scraping shaft frame 41 to rotate around its own axis, driving the expansion ring 42 to rotate. When the expansion ring 42 rotates, the vibration groove 43 squeezes the elastic striking rod 44 in sequence. The striking rod 44 reciprocates along the telescopic shaft, continuously striking the inner wall of the slag collection cylinder 3, shaking off the attached residue and discharging it along with the poured slag, so that the pouring and scraping are completed simultaneously.

[0032] After the operation is completed, the output component 55 rotates in the reverse direction, the arc rod 52 slides along the limit slide frame 51 to reset, the support drive frame 2 drives the slag collection cylinder 3 to rotate back to the horizontal initial position, and the scraper component 4 rotates in the reverse direction to complete the reset. The equipment can immediately enter the next round of slag collection and cleaning operation without human intervention, realizing continuous cleaning.

[0033] Example 2: Please refer to Figure 1 , Figures 3-5This embodiment is a billet slag cleaning machine based on steelmaking operations, including: the striking rod 44 of the scraper 4 adopts a stainless steel telescopic shaft and a high-temperature resistant spring to form an elastic structure, and the contact end is rounded. When it rubs against the vibration groove 43, it ensures smooth extrusion and extension, avoids scratching the surface of the expansion ring 42, and reduces the wear of the striking rod 44 itself, making it suitable for the high temperature and high dust steelmaking operation environment; the transmission arc plate 53, the arc rod 52 and the rotation axis of the support drive frame 2 are completely coincident, ensuring that the flipping and rotation transmission paths are consistent, and there is no jamming, deviation or abnormal noise during operation, reducing the probability of equipment failure.

[0034] During long-term operation, the slag collection cylinder 3 remains stable in position even under high-speed traction and frequent flipping due to the tight fixation of the restraint frame 22. This prevents problems such as cylinder misalignment and weld cracking, effectively avoiding safety hazards such as high-temperature slag leakage causing burns and equipment contamination. After a single cleaning operation, there is no residue adhering to the inner wall, eliminating the need for manual cleaning and significantly improving the efficiency of the production line.

[0035] As can be seen from Embodiments 1 and 2, this utility model, through its two core designs of single-drive synchronous dual action and composite stable support, not only solves the problems of complex structure and discontinuous cleaning of traditional equipment, but also eliminates the defects of unstable slag pouring and incomplete residue cleaning, thus fully meeting the high-temperature, continuous, and efficient operation requirements of steelmaking sites.

[0036] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
