Abstract：Equipment and process parameters of the secondary cooling system are critical to realize high efficiency billet casting for full steel grades. Present authors give suggestions on the design of secondary cooling equipment， based on the industrial practice and model computation including metallurgical length， number of rollers， length of the secondary cooling zone and the type of secondary cooling. Relatively mild and uniform cooling was proposed as the most essential constituents of the high efficiency secondary cooling. During the casting of billets with cross section dimension of 150 mm×150 mm， specific water flow was in the range of 1.0-1.7 L/kg for diversified steel grades with casting speed exceeded 3.0 m/min and use of full water spray nozzles， while the value would be in the scope of 0.7-1.2 L/kg if aerosol spray nozzles were adopted out of the foot-roller region.
