EFFECTS OF COMPOSITION AND PROCESS VARIABLES ON CORE LOSS AND HARDNESS OF LOW-CARBON ELECTRICAL STEELS

The effects of chemical composition and process variables on core loss and hardness of continuous annealed low carbon electrical steels have been studied in an experimental of stastical design. After data were collected from the experiment, statistical analyses were carried out for finding the dominant factors. Factors that influence the core loss, hardness, grain size and texture of low carbon electrical steels are found. Additionally, two regression equations are established to represent quantitative relationships between those dominant factors and two characteristics, the core loss and hardness, of the electrical steels. © 1990.
