The setting of the heat-conducting column 202 is used to transfer heat to the metal in the middle of the furnace body 101, so that the metal in the middle and the metal outside the furnace body 101 are heated at the same time, so that the metal is heated more evenly and the heating efficiency of the metal is improved. The setting of the heat-conducting rod 203 increases the contact area between the heat-conducting column 202 and the metal, and improves the heating effect of the heat-conducting column 202 on the middle metal.
