METHOD FOR Smelting Low Carbon Titanium-Containing Steels

摘要

A method for smelting low-carbon titanium-containing steels, including melting a chromium-nickel charge, slagging, preliminary deoxidation with aluminum in the initial period of metal refining, alloying, subsequent deoxidation with borcal and final deoxidation of the metal, characterized in that preliminary deoxidation with aluminum is performed in an amount of 1.5-2.0 kg / t, subsequent deoxidation with borkal in the amount of 2.5-3.5 kg / t, the final deoxidation is carried out after downloading the slag with a fractional additive of nickel-magnesium alloy in the amount of 8-12 kg / t, and alloying of steel with titanium is carried out after re-downloading the slag by adding titanium to a clean mirror of the metal in the furnace before tapping the metal into the ladle.
