Effect of secondary dendritic arm spacing on center carbon segregation of slab
Steelmaking(2009)
摘要
Effects of different continuous casting processing parameters on the secondary dendritic arm spacing was determined by measuring the secondary dendritic arm spacing under the different working conditions such as the drawing speed,the cooling rate of the secondary cooling water and the over heat extent of the molten steel in production of the 1 900 mm×250 mm slab in Xinggang.Results show that the larger the secondary arm spacing,the higher the permeability and the more serious,the central segregation of carbon.
