Temperature-control program.

Program Pouring temperature [°C] Surface thermal insulation [kJ·(m2·h·°C)−1] Target temperature [°C] Water pipe cooling
Spacing [m × m] Water temperature [°C] Flow rate [m3·h−1]

Program 1 15 1.0 × 1.0
Program 2 15 20 28 1.0 × 1.0 13 2.0
Program 3 15 The thermal insulation coefficient is 20 at early stage and 5 after October. 28 1.0 × 1.0 13 2.0
Program 4 15 Curing with flowing water is conducted at the early stage and the thermal insulation coefficient is 5 after October. 28 1.0 × 1.0 13 2.0
