Improving Refractory Constructions in the System “Steel-Pouring Ladle – Pouring Basket” of CBCM

Resumo

The refractory equipment of the system “steel-pouring ladle – pouring basket” of continuous billet casting machines (CBCM) is considered. Designs of elements of the unit intended for protecting streams of metal in the course of pouring steel are developed. Designs of the unit with the use of inserts made of plastic refractories to prevent passage of air into the metal stream as it is being poured and assure rational parameters of the delivery of argon into the annular groove of the refractory tube are considered. Stability of the pouring process and an increase in the quality of the poured metal are achieved as a result.
