EFFECTS OF VARIOUS TRACE ELEMENTS ON THE … - REFINING STEELS PRODUCED IN ELECTRIC ARC FURNACE

possesses ideal case-hardening properties and has been designed specifically to assure very good fatigue resistance to high dynamic stresses.网页Overview. An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc such as K + and current from the furnace electrodes passes through the charged material.The increasing use of steel scrap in electric arc furnaces means a constant increase in the quantity of residual elements in steels. These residual elements (Cu,
