The thermal conductivity is much higher than that of clay bricks, especially graphite bricks. But its effects can be beneficial or harmful. A large heat loss is a negative effect, but it is advantageous to easily generate slag in the lower part.

When the lower part of the blast furnace is built with carbon bricks, cooling water can be used instead of cooling water, and only air is used for natural cooling. Even some smaller hearths of blast furnaces do not need cooling at all. But generally, the cooling water tank is still used.

Because sometimes the quality of carbon bricks is not good, the hearth is easily destroyed. If there is no cooling water tank, iron slag leakage accidents will occur, and it is not very troublesome to install the cooling water tank. Therefore, the cooling water tank is still used when using carbon bricks.

Very high refractoriness. Does not melt or soften. Only when the temperature is very high, there will be volatilization (>3000℃). However, this temperature cannot be reached in a blast furnace.

The expansion coefficient is small. This is one of the characteristics of carbon bricks, and other refractory materials are far inferior to it. Rapid cooling at high temperatures will not produce cracks, which is a very desirable property for certain parts that are easily damaged due to cracks (such as furnace bottom). Therefore, the furnace bottom bricklaying is mostly made of carbon bricks.
