Description

Technical Field

[0001] The utility model relates to ladle preheating equipment, in particular to a dynamic flame and ladle body vibration type ladle baking system, belonging to the technical field of ladle preheating in steel production. Background Art

[0002] In the steelmaking process, the ladle is an important device used to receive high-temperature molten steel at the lower part of the discharge port of steelmaking equipment such as converters or electric furnaces, and transport the molten steel to the back-end refining process. A cold ladle at room temperature cannot directly receive molten steel at up to 2000 degrees Celsius, which will cause the refractory material of the ladle to crack and break instantly. Therefore, before receiving molten steel, it is usually necessary to bake the ladle as a whole to above 1150 degrees Celsius with an external burner, and then use a hot ladle to receive the molten steel.

[0003] In the existing ladle baking device, after the ladle is hoisted to the baking station, the top burner is moved above the ladle, and the gas and air valves on the burner are opened to bake the inside of the ladle. For example, CN207214046U sets a self-preheating burner on the top of the ladle, and uses the self-preheating burner to recover high-temperature exhaust gas, thereby reducing fuel consumption; the embedded preheating burner extends the burner and the preheating chamber into the ladle baking device, and the flame can directly reach the bottom of the ladle, thereby improving the heat transfer efficiency; the all-fiber structure of the ladle cover reduces the heat absorption of the ladle cover, reduces the heat dissipation of the ladle cover to the outside, and saves energy. In the current market, some of the repurchased scrap steel has good quality and purity, and does not need to be smelted in a converter or electric furnace. It can generally be directly added to the back-end refining process. However, adding cold scrap steel directly to the refining will cause local cold zones in the furnace. Therefore, before the ladle is baked, adding an appropriate amount of scrap steel so that the ladle can be baked and preheated with the scrap steel, and then go to the refining process together to receive the molten steel. This has become a common method for reducing costs and increasing efficiency in the current industry market. The benefit of this method lies in how much scrap steel can be added. Generally speaking, the more scrap steel can be added to the ladle, the more obvious the economic benefits will be. At present, the amount of scrap steel added to conventional domestic ladles is between 3-5 tons, but some manufacturers have added about 8-10 tons of scrap steel in the ladle in order to pursue extreme economic benefits. Since scrap steel is usually large pieces with irregular shapes, the stacking density of the material layer formed is relatively small, so usually the 8-10 tons of material layer has covered nearly 2 / 3 of the ladle volume. CN207214046U only has a good preheating effect on the empty ladle, but fails to fully consider the preheating state when adding scrap steel into the ladle.

[0004] After adding a large proportion of scrap steel, it will accumulate into a thick column in the ladle, which will affect or even hinder the flame of the top burner from transferring heat downward. This will cause the scrap steel on the top to be baked to a molten state by the high-temperature flame, while the scrap steel at the bottom has not yet heated up in time. After the ladle receives the molten steel, a local cold zone will form at the bottom, causing the molten steel to condense. This will not only hinder the implementation of the argon bottom blowing process at the bottom of the ladle in the back-end refining process, but also the condensed molten steel will continue to adhere to the bottom of the ladle, resulting in a significant reduction in the number of times the ladle is used. In addition, since the temperature at the bottom of the ladle cannot be effectively increased synchronously, the original purpose of baking the ladle is lost, and it is prone to cracking, breaking and other accidents when suddenly exposed to ultra-high temperature molten steel. Utility Model Content

[0005] In view of the problems in the prior art of adding scrap steel into the ladle for coordinated baking of the ladle, such as poor preheating and equalizing effect of scrap steel, poor quality of ladle baking, short service life of ladle lining, etc., the utility model provides a dynamic flame and ladle body vibration type ladle baking system. The utility model arranges a burner adjustment mechanism on the top of the ladle, so that the burner can move in the ladle, and then adjusts the position of the burner flame spraying into the ladle, so that the steel materials at various positions in the ladle can be evenly heated, and a dynamic flame is generated by the burner adjustment mechanism, and the dynamic flame improves the thermal shock to the scrap steel in various areas and depths in the ladle; further, a ladle body vibration mechanism is added to the bottom of the ladle, and the material is not a static material layer through the uniform vibration of the ladle, and the high-temperature flue gas generated can even radiate to the bottom position of the lower layer of the ladle, which greatly improves the heating intensity of the scrap steel at the bottom layer, so that the preheating and equalizing effect of the scrap steel will be greatly improved compared with the traditional mode, and the problems of scrap steel condensation and uneven local baking of the ladle are also greatly alleviated, and the service life of the ladle lining is also significantly extended.

[0006] In order to achieve the above technical objectives, the technical solutions adopted by the present utility model are specifically described as follows:

[0007] A dynamic flame and ladle vibration type ladle baking system, the system comprises a ladle, a burner adjustment mechanism, a ladle vibration mechanism and a burner.

[0011] Preferably, the rotary drive module is connected to the telescopic transmission shaft via gears, and the rotary drive module drives the telescopic transmission shaft to rotate via the gears, thereby realizing circular motion of the burner connected to the telescopic transmission shaft in the ladle.

[0012] Preferably, the lifting drive module of the rotary lifting motor is connected to the telescopic transmission shaft through hydraulic bearings, gears, belts or chains, and the lifting drive module drives the telescopic transmission shaft to move up and down to achieve the lifting of the burner.

[0013] Preferably, the upper end of the burner is movably connected to the lower end of the telescopic transmission shaft, that is, the burner can rotate with its upper end as the rotation center, so that the angle between the axis of the burner and the axis of the telescopic transmission shaft is adjustable. Preferably, the movably connected is a hinge.

[0014] Preferably, the angle formed between the axis of the burner and the axis of the telescopic transmission shaft is 5-85°, preferably 15-75°, and more preferably 25-60°.

[0015] Preferably, the ladle baking system comprises a plurality of burners. The plurality of burners are evenly distributed along the circumferential direction of the telescopic transmission shaft and are all movably connected to the telescopic transmission shaft. The inclination angles of the plurality of burners are the same or different.

[0016] Preferably, the ladle body vibration mechanism comprises an upper table, a vibration column, a vibration motor and a lower table. The upper table is arranged at the bottom of the ladle, and the lower table is arranged below the upper table. The vibration column is vertically arranged between the upper table and the lower table. The vibration motor is arranged at one side of the bottom of the vibration column.

[0017] Preferably, the vibration column is a lifting column structure, including a fixed transmission part and a lifting part. The fixed transmission part is arranged on the upper surface of the lower table. The upper end of the lifting part is connected to the lower surface of the upper table, and the lower end of the lifting part is connected to the fixed transmission part. The vibration motor is arranged on one side of the fixed transmission part.

[0018] Preferably, the system includes a plurality of the vibration columns, which are evenly distributed between the upper table and the lower table. Preferably, the plurality of vibration columns form a rectangular array with multiple rows and columns or a circular array with multiple concentric vibration column rings between the upper table and the lower table.

[0019] Preferably, the system further comprises a spring weighing device, which is arranged at the bottom of the package body vibration mechanism.

[0020] In the prior art, all systems for heating scrap steel have fixed burners, that is, the burners heat the scrap steel at the same position in the ladle, relying on heat radiation and physical heat transfer between the scrap steel to heat the steel in the entire ladle. There are technical problems such as uneven heating and heating the same position of the ladle, which shortens the service life of the ladle. The inventor proposes a ladle baking system that can provide "dynamic flames". The burner angle of the system can be adjusted. When using the system, the flame ejected by the burner is in a dynamic position in the ladle, and can directly act on the steel at different positions in the ladle.

[0021] In the present invention, the dynamic flame can be the flame ejected from the burner at different positions in the same plane, that is, the burner rotates in the ladle. Alternatively, the flame ejected from the burner is at different heights in the ladle, that is, the burner moves up and down in the ladle. Whether the burner rotates or moves up and down, the dynamic flame can be generated. In the present invention, the dynamic flame can be generated by the rotation of the burner or by the up and down movement of the burner. The rotation or up and down movement of the burner can be achieved by the burner adjustment mechanism.

[0022] In the utility model, the traditional fixed flame baking mode at the top of the ladle is changed to a dynamic flame baking mode at the top of the ladle. The dynamic flame at the top of the ladle is provided by the action of the burner adjustment mechanism on the burner. For example: the flame ejected from the burner performs a periodic rotational motion of a certain radius with a point on the central axis as the center of the circle at the top of the ladle, so that the flame is dynamically baked in the ladle and will not be fixed at a certain position, which is conducive to improving the overall uniform preheating of the scrap steel in the ladle. The flame ejected from the burner moves up and down at the top of the ladle, so that the flame is dynamically baked in the ladle and will not be fixed at a certain position, which is also conducive to improving the overall uniform preheating of the scrap steel in the ladle.

[0023] Furthermore, the utility model also adds a ladle body vibration mechanism at the bottom of the ladle. When the burner dynamically bakes the ladle and scrap steel, the vibration mechanism synchronously vibrates the ladle and the scrap steel, so that the scrap steel can be turned over and rolled in the ladle, which is beneficial to improve the preheating effect of the dynamic flame on the scrap steel (especially the scrap steel in the lower layer), improve the preheating uniformity of the scrap steel, and avoid the occurrence of local cold zones.

[0024] In the utility model, the burner adjustment mechanism includes a cover plate, a transmission device and a rotary lifting motor. The transmission device includes a transmission seat and a telescopic transmission shaft. The burner is suspended in the ladle at the bottom of the cover plate through the telescopic transmission shaft. When the system is running, the telescopic transmission shaft is driven by the rotary lifting motor, so that the burner can rotate at a constant speed inside the ladle and can also perform periodic rising and falling actions, so as to improve the preheating effect of the scrap steel in the ladle. In other words, the burner performs periodic rotation at a certain speed on the top of the ladle, and while rotating, the burner also performs a certain stroke of up and down reciprocating motion, ensuring that all areas in the ladle are evenly baked by the flame. At the same time, the vibration column located at the bottom of the ladle is driven by the vibration motor to vibrate at a certain frequency at a constant speed, so that the scrap steel material in the ladle is relatively flipped and rolled, thereby improving the problem of too low temperature of the scrap steel in the lower area and improving the overall uniform heating effect of the scrap steel in the ladle.

[0025] In the utility model, the rotary lifting motor includes a rotary driving module. The rotary driving module can drive the telescopic transmission shaft to rotate through a gear set, thereby driving the rotation of the burner and generating a dynamic flame. Alternatively, the telescopic transmission shaft is a hollow structure, the bottom is connected to the burner through a ball valve, and a control rod is arranged inside the telescopic transmission shaft. The rotary driving module controls the rotation of the ball valve through the control rod, thereby driving the rotation of the burner and generating a dynamic flame. For example: the bottom end of the telescopic transmission shaft is connected to the burner through the ball valve, the telescopic transmission shaft is a hollow structure, a control rod is arranged inside the telescopic transmission shaft, one end of the control rod is connected to the rotary driving module, and the other end of the control rod is connected to the ball valve; the rotary driving module is connected to the ball valve through the control rod arranged in the hollow structure of the telescopic transmission shaft; the rotary driving module controls the rotation of the ball valve through the control rod, thereby controlling the burner to make a circular motion in the ladle. Alternatively, a first gear is arranged on the rotary driving module, and a second gear is arranged on the outer wall of the telescopic transmission shaft, and the first gear and the second gear are meshed and connected. The first gear rotates under the action of the driving force of the rotary driving module, and the first gear drives the second gear to rotate, thereby realizing the rotation of the telescopic transmission shaft. The rotation of the telescopic drive shaft controls the burner to make a circular motion in the ladle. Alternatively, the rotary drive module is connected to the telescopic drive shaft using a structure similar to a fan kiln head. In short, no matter which structure is used, as long as the rotary drive module can drive the rotation of the telescopic drive shaft or the burner, dynamic flames can be obtained.

[0026] In the utility model, the rotary lifting motor also includes a lifting drive module, and the lifting drive module is used to realize the up and down movement of the telescopic transmission shaft or the burner. The lifting drive module can be connected to the telescopic transmission shaft through a hydraulic bearing, a gear, a belt or a chain, and the up and down movement of the telescopic transmission shaft is realized through the transmission action of the hydraulic bearing, the gear, the belt or the chain. For example: a hydraulic bearing is provided on the lifting drive module, and the telescopic transmission shaft is sleeved in the hydraulic bearing. The lifting drive module drives the hydraulic bearing to make the telescopic transmission shaft move up and down in the hydraulic bearing, thereby realizing the up and down movement of the telescopic transmission shaft, and then controlling the up and down movement of the burner in the ladle. Alternatively, the rotary lifting motor also includes a lifting drive module, and a gear is provided on the lifting drive module, and a rack is provided on the outer wall of the telescopic transmission shaft, and the gear and the rack are engaged and connected. The lifting drive module drives the gear to rotate, and the gear acts on the rack to drive the telescopic transmission shaft to move up and down, thereby controlling the up and down movement of the burner in the ladle. Alternatively, a structure similar to an elevator is adopted, and the lifting drive module drives the telescopic transmission shaft equivalent to the elevator drive device, and the telescopic transmission shaft is equivalent to the elevator box, and the telescopic transmission shaft is driven up and down by the lifting drive module. In short, no matter which structure is used, as long as the lifting drive module can drive the telescopic transmission shaft or the burner to move up and down, dynamic flame can be obtained.

[0027] In the utility model, a spring weighing device is also provided at the bottom of the ladle. Its purpose is to accurately obtain the weight of the scrap steel added into the ladle before the ladle baking operation is carried out, so as to facilitate the precise adjustment of various parameters of baking and preheating (such as the gas input per unit time, the burner rotation rate, the burner lifting cycle, the burner descending depth and the ladle vibration frequency, etc.), so as to ensure the baking efficiency and the safe operation of the system.

[0028] In the utility model, the spring weighing device plays a role of weighing, which is essentially similar to the function of an electronic scale. Before ladle baking, steel is conveyed into the ladle, and the weight of the steel input into the ladle is weighed by the spring weighing device. Since the weight of the entire ladle baking system is fixed, before feeding, the ladle is empty, and the initial weight of the ladle baking system is weighed; then feeding, the weight of the ladle baking system after feeding is weighed by the spring weighing device, and the weight of the ladle baking system after feeding minus the initial weight is the weight of the steel in the ladle. By obtaining the weight of the steel in the ladle, the baking process parameters are determined. After baking starts, the spring weighing device stops working. Therefore, after the ladle baking system is started, the ladle body vibration mechanism works normally.

[0029] In the present invention, a control device for central control can also be provided. The setting position of the control device has no fixed set point. It can be set next to the ladle for near-side control, or it can be set in a central control room far away from the ladle for remote control. According to the actual working conditions, as long as it can meet the control and adjustment functions of various parameters during ladle baking. The control device of the utility model belongs to the mature parameter feedback adjustment control device category product. Existing products can be directly purchased from the market, and corresponding parameters can be adjusted according to working conditions.

[0030] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0031] 1: The utility model is provided with a burner and a burner adjustment mechanism on the top of the ladle, which can generate a dynamic flame of rotation and lifting in the ladle, thereby improving the thermal impact of the burner on the scrap steel in various areas and depths in the ladle, which is beneficial to improving the uniform effect on the ladle and the scrap steel, so that the problems of scrap steel condensation and uneven local baking of the ladle are greatly alleviated, and the service life of the ladle lining is also significantly extended.

[0032] 2: The utility model adds a ladle vibration mechanism at the bottom of the ladle, which can vibrate the ladle at a uniform speed, causing the scrap steel materials in the ladle to flip and roll relatively, which is beneficial for the high-temperature flue gas generated by the burner to radiate to the bottom of the lower layer of the ladle, thereby improving the heating intensity of the scrap steel at the bottom layer, and further greatly improving the preheating and equalizing effects of the scrap steel compared with the traditional mode.
