High aluminium will also make it more difficult to tap off the liquid slag.

Liquid slag is formed and removed in this process.

This was due to the erosion of the furnace lining by the liquid slag.

Investigations of mass and heat transfer in multi-component liquid slag/metal systems.

Then calcium oxide combines with silicon dioxide to form a liquid slag.

The liquid slag moves out through the hole into a container called slag pot.

At last the liquid slag broke through, jet-black as if it were molten coal, flowing thickly down the clay spout.

The comparatively low kiln temperatures of around 1000 C produced no liquid slag, the residue (gangue) remained in solid form.

It involved taking molten steel from a Bessemer converter and pouring it into cooler liquid slag.

Alternatively, in the pelletization process the liquid slag is partially cooled with water and subsequently projected into the air by a rotating drum.

'It works by cooling the liquid slag with a water jet and turning it into granulated slag.

Slag was removed by liquation, that is, the solid gangue was converted into liquid slag.

The stone and ore form a low-melting, free-running liquid slag, which absorbs most of the sulphur entering the furnace (coke is the main sulphur source).

Dr Floyd had patented a concept of using a water cooled lance to burn fuel and air below the surface of a liquid slag - submerged combustion.

Liquid slag, composed of gangue minerals and oxide components of stone, floats on the liquid iron and is separated from the molten metal during furnace tapping.

Mineral matter removal as a liquid slag is important, particularly for entrained-flow gasification, therefore flux addition will be required if many Australian coals are to be used in these new technologies.

In order to approach these objectives, a good slag should have lower melting temperature, lower gravity and better fluidity to ensure a liquid slag which can be separated well with metal melting.

In this way, for a droplet containing 80 vol% gas and 20 vol% liquid the liquid slag is expected to be in contact with around 34.2% of the interface at any moment causing direct reduction.

An externally supplied shielding gas is sometimes used, but often the flux itself is relied upon to generate the necessary protection from the atmosphere, producing both gaseous protection and liquid slag protecting the weld.

Both electrophoresis and magnetophoresis (movement of material caused by electric and magnetic fields) take place, but their effects are sometimes overwhelmed by the violent stirring of the expanding gases, molten steel, and liquid slag.
