The solution of high-ash carburizing agents (dry-quenching dust, coke breeze) and low-ash agents (MU-95) in molten steel is studied. Relatively stable C–O and C–O–Fe complexes are formed on solution. When high-ash carburizing agents are introdu

A new production technology for vacuum-treated rail steel has been developed, with reduced carbon content (0.10%) at discharge from the furnace and the addition of carbon-bearing materials on ladle intake. This technology reduces the total oxygen con
