采用C+BN作为骨架粒子,研究开发了一种新型的超低碳钢保护渣.其性能可以满足超低碳钢连铸的需要.C+BN作为骨架粒子可以使保护渣的粘度减小、熔化温度降低、熔化速度降低、结晶温度降低.
Using C + BN as the framework particles, a new type of ultra-low carbon steel mold flux was developed and developed to meet the requirements of continuous casting of ultra-low carbon steel.C + BN as the framework particles can reduce the viscosity of the mold flux, The melting temperature decreases, the melting rate decreases, and the crystallization temperature decreases.
