低碳钢板坯连铸专用渣

Slag for Continuous Casting Low Carbon Steel Slab

产品说明: 低碳连铸如何提高拉速（1.5m/min）增加产量一直是炼钢企业关注的焦点，我公司开发了FGY-4型连铸渣，针对性地调整保护渣结晶温度；有效控制半球温度和粘度，在高拉速状态下能保持正常的消耗量和液渣层厚度及合理的传热量，从而保证了结晶器出口端的坯壳厚度，实现无粘结连铸生产。

Product Description: How to improve continuous casting low carbon steel’s casting speed (1.5m/min) and increase productivity are always being the focus of steelmaking industry. Our company has developed FGY-4 slag which can adjust powder’s crystallization temperature and control hemisphere’s temperature and viscosity to keep consumption, thickness of liquid slag and heat transmission in normal range even under high casting speed. Consequently, it can ensure the shell thickness at the delivery end, and finally make unbounded continuous casting manufacture come true.
