$Tank and RH Degasser Refractories - Resco Products$

Degasser

Degasser vacuum degassing has become very important in the steel industry for secondary refining and secondary steelmaking. Steel degassing is typically used today with the former being used typically in integrated shops and later in EAF shops. There are two types of degassers: RH Degasser and Tank Degasser.

RH Degasser Refractories

The RH degassing process initiates when both snorkels located at the base of a tall cylindrical vessel are immersed into the liquid steel. Argon is injected into the molten steel through the upleg snorkel. This causes a pressure differential that leads to the flow of steel up the upleg. It then travels across the bottom of the vessel to the down leg.

Low carbon contents can be achieved through the use of oxygen blowing as the metal is passing through the vessel. Alloys can be added to achieve the final desired chemistry. This results in a ladle full of metal with little or no dissolved gases. It reaches the right chemistry and temperature for eventual casting.

Typically, refractory lined with a magnesia-chrome brick of varying compositions depending on location if used in the vessel. Resco produces this complete range of refractory products. Typical products are Nucon 60, Exceline FG-95, GRFG 100.

Tank Degasser Refractories

$Degasser Refractory Diagram - Resco Products$ Tank degassing is the process of a ladle being placed into the vacuum chamber and then sealed. After a vacuum is created in the chamber argon is injected through the bottom of the ladle. This is done through a porous plug stirring the metal and allowing for dissolved gases to be drawn away. Temperature can be adjusted by arc reheating and chemistry adjusted by alloying.

These are lined with high duty fire clay brick in the safety lining and high alumina bricks in the working lining. Working linings can also be shotcrete with a high alumina composition in the 60% alumina range. Your Resco Products representative will evaluate your processes, conditions, and company goals to determine the optimal products. Resco has industry-standard products and custom solutions depending on your application and conditions.
