ThyssenKrupp Electrical Steel

Pickling The starting material is ultra pure hot rolled coils supplied to precisely determined specifications by carefully selected suppliers. The hot rolled coils are cleaned and de scaled in pickling line.
Cold Rolling After pickling the coils are cold rolled to desired thickness with very close thickness tolerance by using modern guage control methods.
Tandem Annealing, Decarburizing And Coating The cold rolled coils are treated in state of the art continuos annealing, decarburizing and coating line. During decarburizing, the carbon content of the strip is reduced to a level which avoids magnetic ageing. Precisely controlled furnace parameters like strip speed, temperature and composition of inert gas atmosphere are determined as per customers' requirement of properties. The strip is coated on both sides with one of our wide choice of insulations customized to final application requirments.
Slitting/Trimming The finished coils, after extensive quality test, are slitted/ trimmed to the dimensions required by our customers with close width tolerances.
Cut to Length Coils are sheared to customers' specified lengths. Coils can also be sheared in shapes like parallelogram etc.
