| 垂直热通量 | vertical heat flux (The melting rate of a mould powder is affected by a series of factors: (i) the carbon content, (ii) the particle size and the nature of the carbon used, (iii) the vertical heat flux (which depends upon casting speed, turbulence, steel temperature, etc.), and (iv) the presence of exothermic agents in the powder. 结晶器保护渣熔化速度受一系列因素的影响：①含碳量；②粒度和所使用的碳的特性；③垂直热通量(它取决于拉坯速度、紊流状况、钢水温度等)；以及④保护渣中存在的发热剂。) |
