The present invention relates to a magnet for lifting. The magnet for lifting comprises a magnet for applying magnetic force to an object to be lifted, heated at high temperatures, to lift the object; a protective member coupled to surround the outer circumference of the magnet; transmission members coupled to both sides of the protective member; a cover coupled to the outer circumference of one among the transmission members to isolate both sides of the protective member from the outside; and an upper cover having both sides of the underside coupled to the top surface of the transmission members and comprising multiple ventilation holes. Multiple discharge grooves are vertically formed on one inner surface of one of the transmission members while being separated at regular intervals in a longitudinal direction of the transmission members. The high temperature heat of the object heated at the high temperatures is discharged to the outside through the ventilation holes after moving upward along the discharge grooves; thereby preventing the loss of the magnetic force of the magnet due to high temperature. |
