Morphology Tailoring and Enhanced Inclusion Removal of Liquid Melt Film by Regulating the Magnetic Flux Density During Magnetic Controlled ESR Process

A Promising Pressurized Duplex Manufacturing Route of High Nitrogen Stainless Steel

“…After PESR, the proportion of small-size inclusions less than 1.5 μm increased, and the proportion of inclusions larger than 2 μm decreased. The reason is that, first, some inclusions (especially large-size ones) can be absorbed by the slag pool during the aggregation of liquid melting film to form droplets at the electrode tip, the droplets falling through the slag, and the interaction between the liquid slag and the molten steel [36][37][38] ; second, due to the rapid solidification rate of molten steel, the polymerization and growth of inclusions are inhibited. [39,40] However, considering the removal of large-size inclusions after PESR, the average size of inclusion decreased from 1.34 to 1.25 μm.…”

Magnetic‐Flow‐Thermal Characteristics of An Innovative Four‐Channel Induction Heating Tundish

“…For this consideration, the development of tundish heating function has become a hot topic in the past decades to realize narrow range control of steel casting temperature, especially for multi-strand casters. [2] Electromagnetic metallurgy makes use of the magnetic, electrical, force, and thermal effects of electromagnetic fields to affect momentum transfer, [3] shape control, [4] and the preparation of new materials in ref. [5] in metallurgical processes.…”
