抄録

Optimization of the secondary cooling conditions for aluminum DC slab casting is very important because they have a strong effect on the castability and the quality of slabs. The cooling capacities were evaluated by measuring the aluminum block temperature under various cooling conditions. The heat transfer coefficients were calculated with various factors changed. Those factors are the quality of block alloys, cooling surface conditions, amount of water fluxes, water temperatures, water impingement angles, mold lubricant mixing content, and CO<sub>2</sub> gas mixing content. On the basis of the experimental data, the effects of above factors on heat transfer coefficients were quantified. For example, as the water temperature increased every one degree, heat transfer coefficient decreased about 1%, and as the mold lubricant mixing content to cooling water increased every 50 ppm, the coefficient decreased about 1%. It became clear that all cooling factors studied in the present work had a seriously influence on cooling capacities.
