Alumina is obtained from bauxite through the Bayer process.

• Bauxite is crushed and mixed with sodium hydroxide to form a slurry.

• The slurry is heated and pressurized in a digester to dissolve the alumina content.

• The resulting solution is cooled and filtered to remove impurities.

• The purified solution is then heated to precipitate the alumina as a white powder.

• The alumina powder is washed, dried, and calcined to produce pu...read more

The reaction for Al extraction from alumina involves the reduction of alumina using carbon or electrolysis.

• Alumina (Al2O3) is first converted into aluminum chloride (AlCl3) by reacting with hydrochloric acid.

• The aluminum chloride is then reduced to aluminum metal by either carbon reduction or electrolysis.

• In carbon reduction, carbon (usually in the form of coke) is heated with the aluminum chloride to produce aluminum ...read more

There are four main types of cast iron: gray iron, white iron, ductile iron, and malleable iron.

• Gray iron is the most common type and has excellent castability and good machinability.

• White iron is very hard and brittle, often used for wear-resistant applications.

• Ductile iron has high strength and ductility, making it suitable for a wide range of applications.

• Malleable iron is heat-treated to improve its strength and du

Differential is a mechanical device that allows the wheels of a vehicle to rotate at different speeds.

• Differential is commonly found in vehicles with multiple wheels, such as cars and trucks.

• It is located in the center of the axle and connects the drive shaft to the wheels.

• The main purpose of a differential is to allow the wheels to rotate at different speeds while still receiving power from the engine.

• This is importan...read more

EGR system stands for Exhaust Gas Recirculation system. It is used in internal combustion engines to reduce nitrogen oxide emissions.

• EGR system recirculates a portion of exhaust gases back into the engine's intake manifold.

• This reduces the combustion temperature and lowers the production of nitrogen oxides.

• The recirculated exhaust gases also help in reducing engine knocking and improving fuel efficiency.

• EGR systems can...read more

The I-shift automatic gearbox uses helical gears and spur gears.

• I-shift automatic gearbox uses helical gears for the main transmission and spur gears for the auxiliary section

• Helical gears provide smoother and quieter operation compared to spur gears

• Spur gears are used for the auxiliary section as they are more efficient for high torque applications
