[0041] The working principle of the utility model is as follows:
[0042] First, when metal is smelted, inert gas is introduced through the nitrogen blowing inlet 7 in the downward heating tube cover 5, so that the gas flows into the annular groove 6, and then diffuses into the small heating tube 4 fully and evenly through the six air guide holes 12 on the inner edge of the groove, so that the oxygen in the small heating tube 4 is exhausted to avoid the reaction between the smelted metal and oxygen, thereby achieving a highly efficient anti-oxidation function.
