Acidic Bessemer Process
The Bessemer process is a method used for the mass production of steel. It involves the conversion of pig iron into steel by blowing air through it in a converter. The process can be carried out in either an acidic or basic environment, depending on the lining material used in the converter.
In the acidic Bessemer process, the furnace is lined with silica bricks. These bricks are made from silica, which is a compound of silicon and oxygen. Silica bricks have a high silica content, typically around 95%, and are able to withstand the high temperatures and harsh conditions of the converter.
Reasons for using Silica Bricks:
1. Acidic Environment: In the acidic Bessemer process, the lining material must be able to resist the corrosive effects of the acidic slag formed during the conversion of pig iron to steel. Silica bricks are highly resistant to acid corrosion, making them suitable for this purpose.
2. Thermal Insulation: Silica bricks have excellent thermal insulation properties, which help to maintain the high temperature required for the conversion process. They have low thermal conductivity, meaning that they are able to retain heat and prevent it from escaping the converter.
3. Chemical Stability: Silica bricks are chemically stable and do not react with the molten metal or slag during the conversion process. This stability ensures that the lining material does not deteriorate or contaminate the steel being produced.
4. Durability: Silica bricks have a high melting point and can withstand the extreme temperatures inside the converter. They are also able to withstand the mechanical stresses and strains that occur during the blowing of air through the molten metal.
5. Availability and Cost: Silica is a widely available and relatively low-cost material, making silica bricks a cost-effective choice for lining the converter in the acidic Bessemer process.
In conclusion, the correct answer is option 'A' - the furnace is lined with silica bricks in the acidic Bessemer process. These bricks provide the necessary acid resistance, thermal insulation, chemical stability, durability, and cost-effectiveness required for the successful conversion of pig iron into steel.
