PURPOSE: A ladle for aluminum melt which enables long distance transportation by preventing temperature deterioration of the melt, and which prevents cracking of a port to secure safety and enable long term use of the ladle. CONSTITUTION: The ladle(1) for aluminum melt comprises a body(2) on the bottom of which a heat reserving material is laid, and which is formed of a cylindrical metal; a thermal insulating material(5) which is constructed inside the body and consisted of silica board(6), HTB board(7) and a heat insulating material(8); an iron plate(9) which is installed between the thermal insulating materials to prevent leakage of the melt; a port(10) which is installed at the inner side of the thermal insulating material and consisted of a refractory material(12) containing the aluminum melt; a cover(3) which is consisted of ceramic wool(11) and refractory material(12) to cover the body; a packing which is installed on the contact surface between the cover and the body; and a ceramic cone(17) for preventing a melt outlet(16) of the port, wherein the iron plate which is installed between the thermal insulating materials is constructed between the heat insulating material constructed on the body and the HTB board, a heater built-in heater rod is installed at the center of the injection port installed at the cover in such a way that the heater rod is positioned inside the port, and the heater is installed inside the heater rod made of a ceramic based silicon nitride.
