Description

Technical Field

[0001] The utility model belongs to the technical field of mold fluxes for continuous casting, and particularly relates to a baking device for mold fluxes for continuous casting. Background Art

[0002] In the process of continuous casting production, the mold flux plays a crucial role. It can effectively prevent the oxidation of molten steel, absorb inclusions, control heat transfer, and lubricate the billet. However, before use, the mold flux usually needs to be baked, and most of them use simple heating methods, such as resistance wire heating or flame heating, which easily leads to uneven heating and over-baking of some mold fluxes.

[0003] According to the authorized publication number CN211926383U, a baking device for mold fluxes for continuous casting is disclosed. Specifically, when in use, the user pours the mold flux into the screening plate 5 in the baking oven 2 through the feed hopper 11. The mold flux falls to the bottom of the baking oven 2 through the screening plate 5. Then the user turns on two groups of stirring motors one 14, stirring motor two 21 and the air blowing motor 25. At this time, the stirring motor one 14 drives the driving wheel one 15 and the driven wheel one 16 to rotate, and drives the side stirring shaft 17 to rotate. The rotation of the side stirring shaft 17 drives the stirring blade 18 to rotate, so that the mold flux is stirred up and down in the baking oven 2. And the stirring motor two drives the driving wheel two 22 and the driven wheel two 23 to rotate, and drives the stirring screw 24 to rotate, so that the mold flux is stirred left and right in the baking oven 2.

[0004] In the above patent, the basic stirring and baking functions are realized, but the baking turning is uneven, which is easy to cause material jamming due to accumulation, and it is not easy to discharge materials and the discharge of hot air is slow, reducing the working efficiency. Therefore, we propose a baking device for mold fluxes for continuous casting. Summary of the Utility Model

[0026] See also Figures 1-3As shown in the figure, the baking assembly 3 includes a square shell 31 arranged on the top of the connecting plate 212. At the bottom of the square shell 31, there are two groups of blower fans 32 with the same structure. On both inner walls of the square shell 31, there are two groups of square spacers 33 with the same structure arranged at the bottom of the blower fans 32. Inside the square spacers 33, a plurality of water source storage round tubes 39 are evenly arranged.

[0028] Working principle: Workers put the mold powder into the feeding port 4. The mold powder slides into the feeding trough 22 through the slideway 7. The circular surface plate 213 connected thereto is driven by the motor 211 to rotate. The circular surface plate 213 drives the vertically arranged stirring rod 214 fixed at the center to rotate. The stirring rod 214 will linearly move up and down within the square interval provided on the moving plate 215. Further, the stirring rod 214 drives the hinged moving plate 215 to linearly move back and forth left and right at the same time, and at the same time drives two groups of sliding round rods 217 with the same structure arranged at the center positions on both sides of the moving plate 215 to linearly slide back and forth left and right on two groups of supporting seats 216 with the same structure arranged on both sides of the circular surface plate 213. A second limiting plate 218 is arranged on one side of the sliding round rod 217 to drive the connected feeding trough 22 to linearly move back and forth left and right, which is convenient for the mold powder to be turned back and forth by the inertia brought by the linear movement back and forth left and right, so that the heating is more uniform and the working efficiency is improved. Further, when the feeding trough 22 drives the bottom plate 231 to linearly move back and forth left and right at the same time, the telescopic cylinder 234 expands and contracts to drive the baffle 233 connected to the execution end to slide and stretch and close in the inner wall of the execution end of the support chute 232 in the square interval 235 or contract and open, which is convenient for the mold powder to fall from the square interval 235 into the pull-out box 5, avoiding the adhesion and omission of the mold powder. And the above-mentioned linear movement back and forth left and right is carried out on the inner wall of the box body 1 and will not touch the inner wall of the box body 1;

[0029] During baking, two groups of air blowing fans 32 rotate to generate air flow. Multiple water source storage round tubes 39 are filled with water into the inner cavity through the water source box 36. The control valves arranged at the connection of the water source box 36 and multiple water source storage round tubes 39 are used to control the size of the water flow. The inner cavity of the multiple water source storage round tubes 39 is filled with water to half of its capacity to avoid excessive stored water causing overflow. The resistance wire in the electric heating rod 34 arranged in the inner cavity of the water source storage round tube 39 generates resistance heat when an electric current passes through it, so that the water in the inner cavity of the water source storage round tube 39 generates water vapor. Further, the water vapor is discharged from multiple air outlets 38 arranged at the top of the outer wall of the water source storage round tube 39. The air flow generated by the rotation of the two groups of air blowing fans 32 drives the heated water vapor to move downward, which is beneficial to the rapid discharge of the hot air and is convenient for baking the mold powder, so that the heating is fast and uniform. The signal received by the temperature sensor 35 is transmitted into the plc controller, and the plc controller then transmits the electric signal to the electric heating rod 34, and the generation of the water vapor is controlled by controlling the temperature of the electric heating rod 34.
