摘要： In continuously casting steel, at least two pairs of reduction rolls are arranged near the crater top where the solidification of the molten steel in the cast strand is completed, said reduction rolls having a roll pitch of 200 to 420mm and giving a draft per pair of 0.1 to 2.0%, and said cast strand is reduced near the to of said crater, whereby the inner quality of said cast strand is remarkably improved.

摘要： A spray nozzle which has a nozzle main body and opening at one end in fluid communication with an inflow hole passing into the central portion of the nozzle main body. The inflow hole has a rounded orifice portion in fluid communication with an elongated discharge slot at an opposite end of the nozzle main body. Stirring channels extend along and are in fluid communication with the inflow hole. Each stirring channel has a cup-shaped end which is laterally adjacent the rounded orifice portion of the inflow hole. The cut-shaped portion of the stirring holes causes a reverse flow of mixed gas and liquid which passes down the stirring channels such that mixed gas and liquid passing through the inflow hole towards the elongated discharge slot is agitated and a uniform spray with fine droplets is jetted from the discharge slot.
