Description

Technical Field

[0001] This utility model belongs to the technical field of slag feeders, specifically relating to a slag feeder with a weighing system. Background Technology

[0002] A slag feeder is an automated device used in the continuous casting process of steel, primarily for automatically and precisely adding protective slag into the crystallizer. Its core function is to intelligently adjust the amount and frequency of slag added based on process parameters such as steel grade, casting speed, and vibration, using mechanical or pneumatic conveying methods to achieve uniform coverage of the protective slag on the surface of the molten steel in the crystallizer. This equipment can replace manual operation, reduce labor intensity, improve the high-temperature working environment, and ensure the lubrication, heat insulation, and anti-oxidation effects of the protective slag, ultimately improving the surface quality of the cast billet and the efficiency of continuous casting production.

[0003] In the metallurgical industry, slag needs to be added to the furnace before electroslag remelting. Traditionally, the slag is weighed first, then added to a slag feeder, and finally fed into the equipment via vibration. However, this method has several problems, such as the inability to monitor the weight of the slag added and the timing of the addition. One proposed slag feeding mechanism (CN220717726U) with timed and quantitative functions uses a solenoid valve to control the start and stop of slag discharge, achieving quantitative slag discharge. A timer controls the opening and closing of the solenoid valve at regular intervals, ensuring smooth operation of the casting machine. However, this solution lacks precision in monitoring the slag weight, thus failing to accurately control the added slag weight and consequently affecting the quality of the final formed steel. Utility Model Content

[0004] To address the problem in existing technologies where the weight of added slag cannot be accurately controlled, thus affecting the quality of the final formed steel, this invention provides a slag feeder with a weighing system. This system can accurately monitor the weight changes of the slag container to obtain the weight of the added slag, achieving precise slag addition. The specific technical solution is as follows: A slag feeder with a weighing system includes: a device base; three sets of weighing structures are installed on the upper wall of the device base; a container structure is installed on the upper wall of the weighing structures; and a magnetic vibration feeding structure is installed on the upper wall of the device base, with the magnetic vibration feeding structure located at the outlet of the container structure. The three sets of weighing structures include: a weighing base, a pressure sensor, and a weighing top plate. The weighing base is installed on the upper wall of the device base, the pressure sensor is installed on the upper wall of the weighing base, and the weighing top plate is installed on the upper wall of the pressure sensor.

[0005] Preferably, the container structure includes: a container frame, a container body, and an electrically controlled valve; the container frame is installed on the upper wall of three weighing top plates, the container body is installed on the upper wall of the container frame, and the electrically controlled valve is installed at the lower outlet of the container body.

[0006] Preferably, the magnetic vibration feeding structure includes: a feeding riser bracket and a vibrating feeder; the feeding riser bracket is installed on the upper wall of the device base, the vibrating feeder is installed on the upper wall of the feeding riser bracket, and the inlet of the vibrating feeder is aligned with the outlet of the container body.

[0007] Preferably, the inlet of the container body is equipped with a top cover, and the top cover is fixed to the inlet of the container body by a snap fastener.

[0008] Preferably, the upper wall of the cover is provided with a cover opening handle.

[0009] Preferably, the discharge port of the vibrating feeder extends outside the feeding riser bracket.

[0010] This utility model discloses a slag feeder with a weighing system. Compared with the prior art, the advantages are as follows: By organically combining the slag container and the slag conveying device, and installing a weighing device in the slag container, the weight change of the slag container can be accurately monitored, thereby obtaining the weight of the slag to be added. This enables precise slag addition, ensuring the quality of the formed steel. Furthermore, the slag feeding time can be adjusted by regulating the slag feeding speed through the slag conveying device, improving the accuracy of slag feeding weight and time, and increasing production efficiency.

[0012] The following are specific implementation cases and appendices. Figures 1-2The present invention will be further described below, but it is not limited to these embodiments. The present invention provides a technical solution: a slag feeder with a weighing system, comprising: a device base 1, three sets of weighing structures installed on the upper wall of the device base 1, a container structure installed on the upper wall of the weighing structures, and a magnetic vibration feeding structure installed on the upper wall of the device base 1, wherein the magnetic vibration feeding structure is located at the outlet of the container structure; the three sets of weighing structures include: a weighing base 2, a pressure sensor 3, and a weighing top plate 4; the weighing base 2 is installed on the upper wall of the device base 1, the pressure sensor 3 is installed on the upper wall of the weighing base 2, and the weighing top plate 4 is installed on the upper wall of the pressure sensor 3.

[0013] As a preferred embodiment, the container structure further includes: a container frame 5, a container body 6, and an electrically controlled valve 7; the container frame 5 is installed on the upper wall of the three weighing top plates 4, the container body 6 is installed on the upper wall of the container frame 5, the electrically controlled valve 7 is installed at the lower outlet of the container body 6, the inlet of the container body 6 is equipped with a top cover 10, and the top cover 10 is fixed to the inlet of the container body 6 by a buckle, and the upper wall of the top cover 10 is provided with a cover opening handle 11.

[0014] As a preferred embodiment, the magnetic vibration feeding structure further includes: a feeding riser bracket 8 and a vibrating feeder 9; the feeding riser bracket 8 is installed on the upper wall of the device base 1, the vibrating feeder 9 is installed on the upper wall of the feeding riser bracket 8, and the inlet of the vibrating feeder 9 is aligned with the outlet of the container body 6, and the outlet of the vibrating feeder 9 extends out of the feeding riser bracket 8.

[0015] Working principle: Before using this device, the operator connects an external AC power source to the device to provide power to the electrical appliances, and connects the matching controller to the electrical appliances to provide control and operating logic. Simultaneously, the discharge port of the vibrating feeder 9 is aligned with the inlet of the equipment requiring slag. Next, the operator opens the top cover 10 using the handle 11 and adds the slag into the container body 6 through the inlet. At this time, the pressure sensor 3 receives pressure and sends the pressure change back to the electrical appliance. When slag needs to be discharged, the operator inputs the amount of slag to be discharged through the controller. When the controller issues the command to discharge the slag, the electric valve 7 opens, and the slag enters the vibrating feeder 9 through the electric valve 7. At this time, the pressure sensor 3 records the pressure change in real time. When the controller calculates that the pressure change of the pressure sensor 3 reaches the input value, the controller will control the electric valve 7 to close. Since the vibrating feeder 9 and this device open simultaneously, the slag falling into them will enter the equipment that needs to add slag through the outlet of the vibrating feeder 9, thus completing the addition of slag.
