Based on main technical parameters of a new built Φ600 mm圆坯连铸二次冷却数学模型600 mm round bloom caster in steel works
a math model for heat transfer and solidification of one-dimensional non-steady state casting bloom with cylindrical coordinates has been established
and the casting speed
superheating degree and intensity of cooling on temperature of casting bloom is analyzed by using finite differential method to solve and assemble program to carry out the calculation of temperature field of bloom with a given water flow rate. It is obtained with calculation on casting Φ500 mm bearing steel GCr15SiMn bloom that with every increasing casting speed 0. 1 m/min
the thickness of solidified shell of bloom at outlet of mold decreases by 7. 9 mm and the solidification terminal point is prolonged by 6. 7 m.
