Automatic Slag Raking Machine

Product Details

Traditional slag raking relies on manual observation and control of related equipment operations and relies on manual experience to judge and control the slag raking path and depth. This can easily lead to long production times, serious iron loss, excessive or under-removal of slag, and no standard for iron residue in the ladle. To help the industry solve the above problems, our company independently developed an automatic slag raking system.

The automatic slag raking system is a comprehensive system based on intelligent slag raking machines, intelligent analysis, deep self-learning, neural networks and intelligent control, and can realize remote slag raking and remote operation and maintenance. Through the slag surface evaluation function of the automatic slag raking system, the system controls the slag raking machine to move according to the set path to realize automatic slag raking. It is an essential product for intelligent process production and management in the steel industry.


This system mainly includes automatic slag removal, exception handling, and intelligent diagnosis.

The automatic slag raking system establishes communication with equipment such as slag skimming machines, hydraulic stations, desulfurization PLCs and tipping trucks, and controls the intelligent tipping of ladles and the slag skimming machines to operate according to planned paths, improving the stability of slag raking and eliminating the randomness of manual slag raking. It achieves the purpose of unified determination of the endpoint of slag raking, reducing iron loss and improving intelligent control.

1) Inclination sensor – detects the tipping angle of the ladle car.

2) Liquid level radar – detects the liquid level of molten iron.

3) Binocular vision cameras – No. 1 and No. 2 vision cameras. No. 1 vision camera: bale edge identification, slag surface identification, slag surface determination; No. 2 vision camera: path planning, tipping and overflow detection, and redundant design.

4) Remote camera – remote slag raking and large screen display in the operating room.

5) Surveillance cameras – monitor the entire slag raking operation platform to ensure personnel safety.

6) Vision Camera No. 3 – detects the amount of slag in the slag basin to ensure there is no overflow.

7) Displacement sensor – detects the stroke of the slag scraper cylinder.

8) Telescopic encoder – detects the telescopic distance of the slag scraper.

9) Rotary encoder – detects the rotation angle of the slag scraper.
