Description

Technical Field

[0001] This utility model specifically relates to a raw material mixing device for preparing electroslag flux for stripped stainless steel. Background Technology

[0002] Electroslag flux is an indispensable consumable material in the electroslag remelting process. Its compositional uniformity directly determines the electrical conductivity, slag pool temperature field, and the purity of the final metal ingot during the smelting process.

[0003] The existing flux preparation generally adopts the "fixed mixing tank + cantilevered stirring paddle" scheme: the stirring paddle only rotates around a fixed axis, while the tank remains stationary, resulting in the action area of ​​the paddle blade being limited to the fixed cylindrical space; the flux raw materials near the tank wall and bottom remain for a long time, forming a "dead zone", which requires extending the stirring time or manually turning the material multiple times to barely achieve uniformity, resulting in high energy consumption, low efficiency and poor batch consistency. Utility Model Content

[0004] The purpose of this invention is to provide a raw material mixing device for preparing electroslag flux for stripped stainless steel, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material mixing device for preparing electroslag flux for stripped stainless steel, comprising:

[0006] A flux mixing tank, the lid of which has a radially through-hole for mixing clearance;

[0007] A flux-supporting slide is used to position and support the flux mixing container;

[0008] The sliding guide pair allows the flux-carrying slide to be linearly and reciprocally mounted on the melting base;

[0009] The melting and telescopic cylinder has its cylinder body hinged to the melting base and its piston rod hinged to the flux-bearing slide to drive the flux mixing tank to perform horizontal homogenizing reciprocating motion relative to the melting base.

[0010] A flux homogenizing motor is fixedly suspended above the flux mixing tank, and its output shaft drives the mixing pulley through a melting synchronous belt.

[0011] The flux stirring roller is inserted into the melting pulley, with its lower end passing through the melting relief groove and extending into the flux mixing tank cavity. The bottom end is equipped with flux homogenizing blades.

[0012] Under the reciprocating drive of the melting and telescopic cylinder, the flux mixing tank drives the internal flux raw materials to move synchronously, and the flux tumbling roller slides along the melting and dispensing groove and keeps rotating, so that the tumbling and covering area of ​​the flux homogenizing blades dynamically expands, thereby achieving the homogenization of flux raw materials.

[0013] Preferably, the effective sliding length of the flux mixing relief groove is not less than the inner diameter of the flux mixing tank.

[0014] Preferably, the sliding guide pair is a roller guide combination, and the roller is equipped with a melting condition locker for locking the flux-bearing slide during feeding or discharging.

[0015] Preferably, the melt-mix telescopic cylinder is a servo electric cylinder.

[0016] Preferably, the flux homogenizing blades are double-helix strip structures, arranged at intervals along the axial direction of the flux tumbling roller.

[0017] Preferably, a quick-release melting and sealing clamp is provided between the can lid and the flux mixing can.

[0018] Preferably, the flux homogenizing motor is fixedly suspended by a top seat, and the top seat is mounted on the melting base by a connecting support plate.

[0019] The technical effects and advantages of this utility model are as follows: In this raw material mixing device for preparing electroslag flux for stainless steel, the flux mixing tank moves horizontally reciprocating under the drive of the melting and telescopic cylinder. The flux stirring roller slides along the melting and displacement groove, so that the flux homogenizing blades dynamically change their radial position while rotating. The reciprocating translation and rotational stirring are coupled to form a spiral, shearing, convection and composite flow field. The relative displacement between flux raw material particles increases and the batch qualification rate is improved. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] refer to Figure 1 , Figure 2 and Figure 3 As shown, the system includes a flux mixing tank 1 with a radially penetrating mixing clearance groove 3 in its tank cover 2; a flux-carrying slide 4 for positioning and supporting the flux mixing tank 1; a sliding guide pair 5 for linearly and reciprocally mounting the flux-carrying slide 4 on a melting base 6; a mixing telescopic cylinder 7, with its cylinder body hinged to the melting base 6 and its piston rod 8 hinged to the flux-carrying slide 4, for driving the flux mixing tank 1 to perform horizontal homogenizing reciprocating motion relative to the melting base 6; a flux homogenizing motor 9, fixedly suspended above the flux mixing tank 1, whose output shaft drives a mixing pulley 11 via a melting synchronous belt 10; and a flux agitation roller 12 inserted into the mixing pulley 11. The lower end extends through the melting and retraction groove 3 into the cavity of the flux mixing tank 1, and the bottom end is equipped with flux homogenizing blades 13. Under the reciprocating drive of the melting and retraction cylinder 7, the flux mixing tank 1 drives the internal flux raw materials to move synchronously. The flux tumbling roller 12 slides along the melting and retraction groove 3 and keeps rotating, so that the tumbling coverage area of ​​the flux homogenizing blades 13 dynamically expands, realizing the homogenization of flux raw materials. The flux tumbling roller 12 slides along the melting and retraction groove 3, so that the flux homogenizing blades 13 dynamically change their radial position while rotating. The reciprocating translation and rotation tumbling are coupled to form a spiral, shear, convection and composite flow field. The relative displacement between flux raw material particles increases and the batch qualification rate is improved.

[0028] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the effective sliding length of the melting and dispensing groove 3 is not less than the inner diameter of the flux mixing tank 1. The sliding guide rail pair 5 is a roller guide rail combination, and the rollers are equipped with melting condition lockers to lock the flux-bearing slide 4 during feeding or discharging. Binding the roller guide rail combination with the melting condition lockers solves the problem of switching between translational and static modes: unlocking during stirring and locking during discharging or feeding to prevent accidental slippage of the tank, which could cause flux spillage or personal injury. The melting and dispensing telescopic cylinder 7 is a servo electric cylinder, replacing the traditional pneumatic or hydraulic cylinder to achieve digital closed-loop control of stroke, speed, and acceleration. It can interface with the MES system and automatically call different homogenization curves according to the flux formula. The flux homogenizing blades 13 have a double-helix ribbon structure and are spaced apart along the axial direction of the flux agitation roller 12. The double-helix ribbon structure forms a continuous propulsion-return circulation in the axial direction and generates shear laminar flow in the radial direction, which can quickly disperse easily agglomerated fine powder and prevent fish-eye agglomerated particles from entering the electroslag process and causing slag inclusion. A quick-release melting sealing clamp 14 is provided between the can lid 2 and the flux mixing tank 1, which facilitates the immediate removal of the can lid 2 for high-pressure water rinsing after each batch of materials is completed, shortening the inter-batch cleaning time and improving equipment utilization. The flux homogenizing motor 9 is fixedly suspended by a top seat 15, which is mounted on the melting base 6 through a connecting support plate 16.

[0029] In use, first pour the components of the stainless steel electroslag flux into the flux mixing tank 1 according to the formula weight. After closing the tank lid 2, lock the quick-release melting sealing clamp 14 and ensure that the high-temperature resistant ceramic fiber sealing ring is pressed tightly to prevent dust from escaping. The flux homogenizing motor 9 drives the melting pulley 11 through the melting synchronous belt 10, causing the flux stirring roller 12 to rotate. The double spiral ribbon flux homogenizing blades 13 form an axial circulating flow. The servo electric cylinder pushes the flux carrying slide 4 to make horizontal homogenizing reciprocating motion along the sliding guide pair 5. The flux stirring roller 12 slides synchronously in the melting relief groove 3, and the stirring coverage area dynamically expands. The flux homogenizing motor 9 stops first, and the servo electric cylinder resets the flux mixing tank 1 to the initial center position. The melting condition locker is locked again to ensure that the tank does not shift during subsequent operations.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
