OXYGEN LANCE MANIPULATOR

The carbon-oxygen lance mainly refers to the EAF smelting, generally referring to the carbon-oxygen lance at the EAF furnace door, as well as the furnace wall carbon-oxygen burners also called KT lance. The EAF electric arc furnace door carbon-oxygen lance manipulatoris equipped with two water-cooled nozzles, some with two water-cooled oxygen lances, and some with combination oxygen lances.

The former consists of two oxygen lances arranged around, one is a Laval supersonic oxygen lance and the other is a carbon lance used for direct hole carbon powder spraying; The latter is equipped with two spray lances arranged above and below the overall lance, with a supersonic oxygen lance below, which is also a Laval nozzle, and a carbon lance above.

ADVANTAGES

OXYGEN LANCE MANIPULATORADVANTAGES

During smelting, the spray lance inside the furnace door gradually inserts into the furnace as the scrap steel melts. Compared with traditional smelting processes, the use of EAF carbon oxygen lance has the following advantages:

The furnace door carbon oxygen lance injects oxygen into the molten pool at Mach 2 supersonic speed, which changes the Chemical equilibrium in the molten pool and greatly increases the amount of CO in the molten pool.

The whole process of foam slag smelting, due to the participation of carbon injection, the conditions for the whole process of foam slag smelting are improved, the splash is reduced, the power utilization rate is increased, the noise is reduced, and the quality is improved;

As the temperature of the flue gas increases, sufficient oxygen reacts with carbon. Compared with traditional systems, free oxygen is used for CO combustion during decarbonization, resulting in a weaker oxidizing atmosphere in the furnace, reducing electrode and refractory consumption.

WHY

WHY SUCH LANCE MANIPULATOR SYSTEM IS NEEDED?

Carbon removal.

Promotion reduction reaction.

Slag forming.

Horizontal stirring of liquid bath.

Remote control.

Optimal height (up and down) adjustment for different process stages.

Increase of oxygen efficiency and productivity.

Increase of chemical reaction to speed up liquid melting down.
