The Production of Superior Quality Continuously Cast Steel 700169
Facilities have been developed and put into operation for continuous casting of aluminum-killed steel using conventional melt practices. A vertical-type billet machine was installed which casts 200-ton heats in approximately 120 minutes, into four 42-in. long, water-cooled, copper molds, at a rate of 44 in./minute/strand. After casting 10,000 tons of alloy and carbon steel billets, results show the material is better than conventionally cast steel in surface quality, chemical uniformity, and internal cleanliness.
