PURPOSE: A metal melt transferring tube assembly is provided to remove a fusion factor of a magnesium board by a deflection of a front end part of a ceramic nozzle by absorbing a thermal expansion quantity of a transferring tube by itself. CONSTITUTION: A metal melt transferring tube assembly (100) comprises a transferring tube pipe (110), a thermal expansion absorbing unit (120), and a one-touch joint unit (130). The thermal expansion absorbing unit self-absorbs a thermal expansion quantity of the transferring tube pipe generated in a temperature compensation process of the transferring tube pipe to a longitudinal direction. The thermal expansion absorbing unit forms some parts to a longitudinal direction of the transferring tube pipe as bellows shape. The one-touch joint unit comprises a pipe rib, a tube rib, and a joint fixing ring. [Reference numerals] (AA) VIII-VIII cross-sectional diagram
