Main Functions

· Oxygen blowing and injection

· Carbon injection operation

· Burner positioning and movement

· Furnace temperature and combustion control

· Remote and automatic lance operation

· Safe lance movement in high-temperature environments

The system significantly reduces manual operation near the furnace and improves operational stability and safety.

Main Components

A complete lance manipulator system generally includes:

· Manipulator main frame

· Lance arm assembly

· Servo or hydraulic drive system

· Lifting and telescopic mechanism

· Rotation and positioning system

· Oxygen lance or burner assembly

· Water-cooling system

· Electrical control cabinet

· PLC automation and remote-control system

· Sensors and safety protection devices

Customized configurations are available according to furnace type and process requirements.

Working Principle

The lance manipulator operates through hydraulic, electric or servo-driven movement systems which control the lifting, extension, rotation and positioning of the oxygen lance or burner.

During furnace operation, the manipulator accurately adjusts the lance position according to process requirements, allowing oxygen, fuel gas or carbon materials to be injected into the furnace with optimized angle and distance.

The integrated automation system enables stable operation, precise control and real-time adjustment while protecting operators from direct exposure to heat, dust and arc radiation.
