摘要
Abstract: The influence of Ca-containing additional alloy on the composition and contamination of steel 26KhMFBA with non-metallic inclusions during secondary refining and continuous casting is investigated. It is shown that the use of the SK30wire silicocalcium alloy after degassing leads to the inoculation of refractory aluminate inclusions and, as a consequence, to a decrease in the total inclusions rating. The presence of low-melting inclusions is more preferable, since this type of inclusions is not deposited on the pouring nozzle walls and does not adversely affect the contamination of the continuously cast billet and products obtained from it. © 2021, Allerton Press, Inc.
