PROCESS FOR CONTINUOUS CASTING OF ULTRALOW-CARBON ALUMINUM-KILLED STEEL. |
摘要 |
<p>A process for the continuous casting of ultralow-carbon aluminum-killed steel, wherein rusting can be prevented by conducting the casting under such a condition that the concentration of calcium is 6 to 20 ppm by weight, that of sulfur is 0.010 wt% or less, that of oxygen is 30 ppm by weight or less, the degree of superheating of molten steel in a tundish is 16 DEG C or above, and the average flow rate of molten steel in the straight barrel portion of a nozzle is 1.2 m/sec or above. Also the swelling of cold rolled steel sheet can be prevented, because it is unnecessary to blow gaas into an immersion nozzle. <IMAGE></p> |
