Description

Technical Field

[0001] This utility model relates to a slag cleaning device for the under-furnace track of a metallurgical converter, belonging to the technical field of converter smelting equipment in the metallurgical smelting industry. Background Technology

[0002] The standard configuration for the under-furnace section of a metallurgical converter is two cars: a ladle car and a slag car. During converter smelting, slag accumulation on the under-furnace tracks is common due to various factors, including slag spillage during smelting, waste slag removal after smelting, and slag falling during charging. Although slag chutes are installed on both sides of the under-furnace tracks, the amount of scattered slag is still significant, requiring regular manual cleaning and maintenance. While the ladle and slag cars are equipped with track cleaners, these only clean the surface and essentially push the slag back and forth. If slag is not regularly cleaned manually on both sides of the under-furnace tracks, the accumulation will increase, potentially leading to ladle car derailment and frequent accidents involving wheel damage to both cars. Utility Model Content

[0003] The purpose of this invention is to provide a slag cleaning device for the under-furnace track of a metallurgical converter, which enables directional mechanized cleaning of slag accumulated on the under-furnace track, ensures the normal operation of ladle cars or slag cars, and solves the problems existing in the background art.

[0004] The technical solution of this utility model is:

[0005] A slag-collecting device for the underside track of a metallurgical converter includes a scraper, a support body, a pin A, a counterweight, a wire rope, an electro-hydraulic actuator, a balance arm, and a pin B. The upper end of the support body is rotatably connected to the end beam under the vehicle body via pin A, and the lower end of the support body is fixedly connected to the scraper. One end of the balance arm is rotatably connected to the vehicle body via pin B, and the other end of the balance arm is connected to the counterweight via a wire rope. The counterweight is fixed to the support body, and the middle of the balance arm is connected to the electro-hydraulic actuator.

[0006] The slag scraper is provided with a notch that matches the lower track of the metallurgical converter.

[0007] The middle of the balance arm is connected to the electro-hydraulic actuator via a connecting seat.

[0008] The electro-hydraulic thruster is fixed to the vehicle body via a tailstock.

[0009] The upper end of the wire rope is connected to the counterweight via a rope clamp, and the lower end of the wire rope is connected to the counterweight via a lifting lug.

[0010] The beneficial effects of this utility model are: it enables directional mechanized cleaning of slag accumulated on the underside track of the converter, ensuring the normal operation of ladle cars or slag tank cars. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and examples.

[0017] See attached document Figure 1-4 A slag cleaning device for the underside track of a metallurgical converter includes a scraper plate 1, a support body 2, a pin A3, a counterweight 4, a wire rope 7, an electro-hydraulic actuator 8, a balance arm 11, and a pin B12. The upper end of the support body 2 is rotatably connected to the end beam under the car body 13 via the pin A3, and the lower end of the support body 2 is fixedly connected to the scraper plate 1. One end of the balance arm 11 is rotatably connected to the car body 13 via the pin B12, and the other end of the balance arm 11 is connected to the counterweight 4 via the wire rope 7. The counterweight 4 is fixed to the support body 2, and the middle of the balance arm 11 is connected to the electro-hydraulic actuator 8.

[0018] In this embodiment, refer to the appendix Figure 1-4 The slag scraper 1 is fixed to the lower end of the support body 2 by bolts. The slag scraper 1 has a notch 16 that matches the lower track 14 of the metallurgical converter. The upper end of the support body 2 is rotatably connected to the end beam under the car body 13 by a pin A3. The counterweight 4 is fixed to the upper part of the support body 2. The tailstock 6, wire rope 7, electro-hydraulic thruster 8, rope clamp 9, connecting seat 10, balance arm 11, and pin B12 are all installed on the ladle car or slag car. One end of the balance arm 11 is rotatably connected to the car body 13 by the pin B12, and the other end is connected to the counterweight 4 by the wire rope 7, lifting lug 5, and rope clamp 9. The middle of the balance arm 11 is connected to the electro-hydraulic thruster 8 by the connecting seat 10. The electro-hydraulic thruster 8 is connected to the tailstock 6.

[0019] In practical applications, such as Figure 1-4As shown, after the converter smelting is completed, each time the ladle car enters the furnace to receive molten steel, as the empty ladle on the ladle car moves towards the tapping position, the tapping car drive motor is energized, and the electro-hydraulic actuator 8 is energized, extending the push rod. The balance arm 11 rotates upward around the pin 12, and the wire rope 7 lifts the counterweight 4, driving the support body 2 and the slag scraper 1 to rotate to the mechanical stop position. The slag scraper 1 falls, and the notch 16 inserts into the rail 14. The ladle car collects and cleans the slag on both sides of the rail as it moves. When the ladle car reaches the slag dumping position and stops, the electro-hydraulic actuator 8 is de-energized. The counterweight 4, under the force of gravity, pulls the wire rope 7 to rotate the balance arm 11 downward around the pin 12. At the same time, it acts on the support body 2, causing the slag scraper 1 to rotate upward and lift, achieving unidirectional controllable selective slag cleaning.
