Why high quality silicon steel is used in dc machine?

to provide mechanical balance for the rotor. to reduce eddy current. Because of magnetic losses, rotor is built using armature core which in turn is made with many low-hysteresis silicon steel laminations.

Where is silicon metal used?

Metallurgical grade silicon is known as silicon metal because of its lustrous appearance. Silicon is used mainly in the manufacture of silanes and silicones, as a “hardener” or alloying element to produce aluminium alloys, and in the manufacture of micro-processors and solar cells.

Why silicon is used in stainless steel?

Silicon also improves oxidation resistance and is a “ferrite” stabilizer. In “austenitic stainless steels, high silicon contents improves resistance to oxidation and also prevents carburizing at elevated temperatures (309 and 310 are examples).

What is silicon steel and what does it do?

What It Is. Silicon steel is a mixture of iron with a silicon content of up to 3.2\%. The silicon addition improves the magnetization of the steel and its electrical resistivity (the opposite would be electrical conductivity). Adding silicon increases irons’ electrical resistivity up to 5 times.

What is silicon used for in construction?

Silicon is not only used in the construction industry, but high tech equipment like computer chips, solar panels, and transistors are all made up of silicon. The fact that silicon can act as a semiconductor, by allowing control of electrical current, makes it ideal for virtually all electronic equipment.

What are the uses of metallurgical silicon?

Nearly half of all metallurgical silicon is used by the chemical industry to make fumed silica (a thickening agent and desiccant), silanes (a coupling agent) and silicone (sealants]

What is the use of nonoriented silicon steel?

However, it has not supplanted nonoriented silicon steel, which is used extensively where a low-cost, low-loss material is needed, particularly in rotating equipment. Mention should also be made of the relay steels, used widely in relays, armatures, and solenoids.
