| 摘 要： | 通过提高保护渣碱度以及渣中CaF2和Li2O含量，对中碳钢板坯用保护渣进行了优化，并采用优化的保护渣进行了提高拉速工业试验。结果表明：优化的保护渣具有较高结晶温度、较低的粘度和熔点；试验过程中，采用优化的保护渣液渣层厚度平均增加约2 mm，单耗增加0.03 kg/m2；采用优化的保护渣在1.5 m/min拉速下和采用原渣在1.3 m/min拉速下浇铸时，结晶器传热强度、传热的稳定性以及浇铸出的铸坯质量等项目水平相当。

| Abstract: | By increasing basicity and contents of CaF2 and Li2O,the mold flux for medium carbon steel slab casting was optimized.The optimized flux was adopted in plant trial of increasing casting-speed.The results showed that optimized flux has higher crystallization temperature,lower viscosity and melting point.In plant trial,liquid optimized flux thickness increased by 2 mm approximately,slag consumption increased by 0.03 kg/m2.At a casting speed of 1.3 m/min,heat-transfer intensity,stability and slab quality cast ... |
