冯军, 陈伟庆. Effect of Concasting Technology Parameters on Center Carbon, Segregation of High Carbon Steel Billet[J]. Special Steel, 2005, 26(4): 33-35.DOI:
The each technology parameters in range of carbon 0.58% -0.83%
water ratio in secondary cooling zone 0.82-2.86 L/kg
casting speed 1. 9 〜3.0 m/min and superheating of liquid steel 17 ~ 60 ℃: on center carbon segregation of 140 mm x 140 mm and 150 mm x 150 mm billet has been analyzed at given mould electromagnetic stirring (230 ~ 245 A) using multivariate linear regression analysis
and the predicted calculation was carried out using Back Propagation (BP) neural networks. Hie results by multivariate regression analysis showed that the carbon content in steel was remarkable factor to influence the center carbon segregation
next were casting speed and water; and with carbon content in steel
casting speed and superheating of liquid steel increasing
the center carbon segregation in billet increased and with water ratio in secondary cooling zone increasing
