font-size: 12px;">Continuous Casting Process</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Strand Formation:&nbsp;Molten metal is poured into a mold and begins to solidify.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Solidification:&nbsp;The metal continues to cool and solidify as it is withdrawn from the mold.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Secondary Cooling:&nbsp;Further cooling is applied using water or air sprays.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Straightening:&nbsp;The metal is straightened to remove any curvature.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Cutting:&nbsp;The metal is cut to the desired length.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Types of Continuous Casting Machines</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif;
