NOZZLE FOR PREVENTING THE TEMPERATURE OF MOLTEN METAL FROM DROPPING WHICH HAS 2.0 - 3.5:1 IN THE RATIO OF THE HEIGHT OF SUPPLYING UNIT TO THE LENGTH OF BODY

摘要

PURPOSE: A nozzle for preventing the temperature of molten metal from dropping is provided to have the sufficient amount of molten metal in a nozzle by forming the mid-portion of nozzle long so that even in the case that the eddy current is generated when the initial molten metal is flowed in, the eddy current is generated at the upper portion, thereby preventing the flow of molten metal from being disturbed.;CONSTITUTION: A nozzle for preventing the temperature of molten metal from dropping includes a body (11) and a supplying unit (12). The supplying unit is supplied with molten metal by being formed at the center portion of the body. The ratio of the height of supplying unit to the length of body is 2.0 - 3.5:1. In the supplying unit, the content of the molten metal is at least 1kg or greater.;COPYRIGHT KIPO 2013
