连铸保护渣

中碳钢板坯连铸专用保护渣

Slag for Continuous Casting Medium Carbon Steel Slab

产品说明: 中碳钢正处于包晶反应的成份区域,连铸坯很容易出现纵裂缺陷,通过选择控制合适保护渣结晶温度、析晶率和粘度，得到适当的热流密度，确保铸坯均匀缓冷，实现中碳钢连铸良好的铸坯表面质量。

Product Description: Medium carbon steel is at peritectic spot, so it’s frequent to find longitudinal cracks on continuous casting slabs. The crystallization of slag at appropriate temperature, rate and viscosity, ensures the slab undertakes slow-cooling evenly with proper heat-flow density. Therefore, it can guarantee the surface quality of the slab good.
