CONTINUOUS CASTING LINGOTIERE, ESPECIALLY PLATE LINGOTIERE FOR CONTINUOUS CASTING OF SLABS AND BLOOMS

摘要

P Each side wall of this mold has a support wall to which is fixed, by screws 14, an inner plate 6 whose inner side is in contact with the molten metal and whose face applied against the wall d the support has cooling channels formed by slots 13. In order to optimize cooling, the width 19 of the cooling fins 21 between the slots 13 is less than or equal to 13 mm and the flow speed of the cooling fluid is adjusted so that the heat transfer coefficient between the inner plate 6 and the fluid is from 20 to 70 kW / m ** 2K, preferably from 25 to 50 kW / m ** 2K, so that the heat flux density for the inner plate 6 is greater than the heat flux density for a smooth inner plate, without fins. /P
