The utility model discloses an it smelts with a center section of thick bamboo to erect jar magnesium, assembly use in being equipped with the erecting jar of suitable for reading and end opening, including section of thick bamboo body, section of thick bamboo body bottom compresses tightly in end opening department and seals the end opening, evenly is equipped with into array distribution's circular port or bar hole on the section of thick bamboo wall of section of thick bamboo body, the geometry in circular port and bar hole all is less than the diameter of magnesium reduction pellet, is equipped with the coat of nai high temperature oxidation resistance on section of thick bamboo body, through perhaps adopting the mode that is able to bear or endure the high temperature oxidation resistance ceramic material preparation with section of thick bamboo body itself because section of thick bamboo body is equipped with the coat of nai high temperature oxidation resistance to getting rid of the in -process of reducing slag, even have in a large amount of air admission erects jar, the oxidation can not take place for a section of thick bamboo body yet, thereby has solved the short -lived of a central section of thick bamboo, need often change, has still increased the problem of cost when influencing production efficiency.
