Development of CSP Mold Powder for Casting High-Ti Micro-Alloyed Steel in Lianyuan Steel
(0) China have the largest reserves of Ti and the largest production of continuous cast and continuous rolled thin slabs in the world. But, the high-Ti micro-alloying hasnt been applied widely to thin slab production yet. With upgraded control of metallurgical process and consideration of temperature evenness of slabs, many slab producers commence developing high-Ti steel. Tests found, during casting high-Ti steel, inclusions like TiN, TiO2, Al2O3 in molten steel make properties of the mold powder change a lot. After casting a heat, content of TiO2 in powder was 1.85%, which increased from O at initial stage, the softening temperature of powder was 1018℃, which riser from initial 851℃, and the hemispherical temperature and flow temperature changed less. Use of for-high-Ti-steel mold powder can increase both the heat flux density of copper plate appropriately and the inclusion adhesion.
