Inert cathode carbon blocks are a new type of cathode material known for their excellent conductivity, thermal shock resistance, and mechanical strength. They effectively allow aluminum liquid infiltration and resist chemical corrosion from aluminum and electrolytes. Suitable materials include carbonized titanium carbide (TiC), niobium nitride (NbN), and titanium boride (TiB2).

Titanium boride-coated carbon blocks are created by mixing titanium boride (TiB2), resin glue, and carbon materials with a solvent and a curing agent. This mixture forms a 5mm~10mm thick coating on standard carbon blocks, which is cured at 150°C~300°C for 40hrs~50hrs and then cooled slowly.

These coated blocks provide good electrical conductivity, improve aluminum's interaction with carbon, and reduce sodium and electrolyte penetration and erosion. Alternatively, a carbon paste with TiB2 can be pressed onto the surface of the block and roasted together.

Carbon raiser, also known as carbon additive or recarburiser, is a material added to molten metal to increase its carbon content. When being used in steelmaking or casting, the fixed carbon of carbon raiser can reach more than 95%.

During the smelting process of iron and steel products, factors such as smelting time, holding time, and overheating can lead to an increased loss of carbon elements in the liquid iron. This results in a lower carbon content than the expected theoretical value needed for refining. To compensate for the carbon that is burned off during the smelting process, substances that contain carbon and are added to the mixture are referred to as carburizers.

For casting processes involving cast iron, cast steel, and other castings, carbon is essential. The use of a carburizer increases the carbon content in liquid iron. In smelting, a common charge includes pig iron, scrap, and return charge. While pig iron has a higher carbon content, its purchase price is generally higher than that of scrap, which leads to an increased use of scrap and a reduced amount of pig iron. The addition of a carburizer can help lower the cost of castings.

Carburizers serve multiple purposes: they can compensate for the carbon loss that occurs during steel smelting, ensuring that the desired carbon content is achieved for specific steel grades. They can also be used for adjustments after the initial processing. As a crucial raw material for molten iron in induction furnaces, the quality and application of the carburizer significantly impact the condition of the molten iron.
