Since carburization and an excessive oxidation will cause the deterioration of magnetic properties of the steel,
the atmospheric gas must be carefully controlled and the gas must also have a low dew point.
For the prevention of the carburization during annealing,
organic compounds such as oil and grease remained on the coil surface during the fabrication must also be removed completely in advance.
The use of material of low carbon content is recommended for the base and cover of the annealing furnace.
1 Avoiding rust and aging:
(1) Due to slitting and punching, that broken coating film, the ruptured surface will easily
rusted, particularly in summer season when the relative humidity is high. So, it needs
careful package and anti-rust treatment.
(2) For having better magnetic property, Electrical steel generally was produced without
temper rolling process. To avoid coil break in slitting process, it is necessary to keep coils
away from long storage time.
2 Stress-relief annealing
Magnetic properties of Electrical steel coils will be deteriorated by mechanical strains
when it was sheared and punched into laminations or cores. In order to relieve these stress
and restore the original magnetic properties, general stress-relief annealing is necessary.
The following points are observed when laminations or cores are processed to stress-relief
annealing.
(1) There are two kind of coating films to be used in CSCI Electrical steel coils and they are
adapted to various annealing temperature. Please refer the information of table 10 when
stress-relief is necessary to be done.
(2) The magnetic property almost was not affected by ordinary industrial cooling rate scale,
but abrupt heating and cooling will make distortion in cores. However, cooling should be
taken until it reaches 350˚C so that no strain will occur in material.
(3) Since decarburization and excessive oxidation will affect the deterioration of magnetic
properties of steel, the atmospheric gas must be carefully controlled and the dew point
must be kept low. On the other hand, the oiled grease remained during fabrication also
must be removed completely, and the low carbon materials are recommended to be used
in the base and cover of annealing furnace.
